13 XR6/XR Troubleshooting Manual About safety All Nautel transmitters are designed to meet the requirements of EN605, Safety Requirements for Radio Transmitters. The philosophy of EN605 is that the removal of any cover or panel that can only be opened using a tool is a maintenance activity, and that any person performing a maintenance activity is expected to be trained for that activity. Under EN605, it is assumed that trained personnel will be knowledgeable and will take precautions such as removing all power to the transmitter before accessing its components. Electrical hazards To remove power from the transmitter, switch off and lock out the ac power. There are three amber LEDs at the bottom rear of the cabinet that glow to remind anyone who has not turned off the power that the system is live and serious danger is present. WARNING: It is not enough to remove RF power. The power line is still connected. Mount the transmitter ac power disconnect switch/breaker close to the transmitter so that it can be reached quickly in an emergency. Clearly label the disconnect switch/breaker (e.g., EMERGENCY SWITCH). After turning off the power, always perform a measurement to confirm that the power is off before touching anything within the transmitter. If the wrong breaker was opened, the equipment will be live. WARNING: Do not use an ordinary multimeter to check for voltage, since it may have been left inadvertently on the AMP (A) range, triggering a short and an arc blast that could result in severe burns and even death. Use only a non-contact voltage probe or a safety voltmeter (available from vendors such as Fluke, Ideal, and Teagam). Use a proper lockout procedure to ensure that another worker cannot accidentally reapply power while you are performing maintenance on any part of the transmitter or site. Issue Page xiii

14 XR6/XR Troubleshooting Manual Lightning hazards Before opening the transmitter and touching internal parts, remove and solidly ground the antenna connection. WARNING: It is not enough to ground the antenna terminal with the antenna still connected. Even a small impedance in the ground strap will result in lethal voltages during a lightning strike. RF hazards A serious RF hazard and very high voltages exist in the vicinity of the antenna and its networks during normal operations. Toxic hazards There are devices used in this equipment containing beryllium oxide ceramic, which is non-hazardous during normal device operation and under normal device failure conditions. These devices are specifically identified with (BeO) in the Description column of the Troubleshooting Manual s parts list(s). Do not cut, crush or grind devices because the resulting dust may be hazardous if inhaled. Unserviceable devices should be disposed of as harmful waste. Other hazards Ensure that appropriate fire alarms and fire extinguishers are available. Extinguishers must be suitable for use on electrical fires. Many other site safety risks exist. It is beyond the scope of this manual to identify all the risks and procedures. Page xiv Issue

15 XR6/XR Troubleshooting Manual Safety precautions This section provides very important information about protecting the safety of personnel and equipment: Personal safety - see page xv Site safety - see page xvi Equipment safety - see page xviii Personal safety Training The training of any personnel who will have physical access to the site or the transmitter is very important. Personnel must be familiar with the transmitter, so that they can avoid physical danger, and be aware of hazards to themselves and the equipment. Nautel offers a number of training courses covering the basic fundamentals of RF systems and transmitters, and the operation and maintenance of the transmitter. For more information about available courses and schedules, go to the Nautel website at or ask your Nautel sales representative. Site orientation When you give personnel access to the transmitter site (e.g., hiring new personnel, or giving access keys to personnel), perform a site orientation to ensure that they are familiar with the site, on-site procedures, and on-site hazards. Cover the following topics: Securing the site (locking doors and fences) to prevent unauthorized access How and when to call for technical support or emergency assistance Areas of the site and pieces of equipment that are off limits Issue Page xv

16 XR6/XR Troubleshooting Manual Voltage awareness Ensure that all personnel that are able to access areas with high voltage circuits or high field strengths are aware of the hazards associated with high voltage. Cover the following topics: High voltage or high field strength areas where caution is required Physical risks of electric shock Risks for personnel with pacemakers or other medical implants Induced voltages in high field strength areas On-site risks during thunderstorms and lightning strikes Operation of safety interlocks (if installed) First aid Nautel does not offer first aid training, since the hazards associated with high voltage and RF energy are not specific to the transmitter. However, the customer should provide first aid training to all personnel who have access to the transmitter site. First aid training should include CPR, care of burns, artificial respiration, and defibrillation if specific equipment is available on-site. Site safety Controlling access Transmitters and antennas generate and carry dangerous voltages that can be harmful or fatal. It is very important that you control access to the site and its equipment. To secure your transmitter site, use: Locking steel or security doors to prevent casual access A perimeter fence to keep trespassers away from the antenna system and feedline No Trespassing signs An alarm system Page xvi Issue

17 XR6/XR Troubleshooting Manual Marking hazards Place warning signs close to any hazardous areas or systems (e.g., the feedline or the antenna system). Make the signs large enough that they cannot be missed. Provide signage in all languages used in the region. These signs are intended not only for authorized personnel, but also for emergency responders or accidental trespassers. Qualifying site personnel Make sure that personnel who have access to the site are qualified to work around electronics and high voltage systems. Ac power protection You should take steps to protect equipment from surges (over-voltage spikes) on the ac power lines. Surges may occur during thunderstorms, or because of malfunctions in the electrical distribution grid. Surge suppressors and ac power conditioners can prevent serious damage to your on-site equipment, including the transmitter. RF protection Transmitters and their antenna systems create intense radio frequency fields at the transmitter site, particularly near the feedline, antenna and tower. At some sites, these fields may cause biological effects, including the heating of body tissues. Intense fields can also create dangerous high voltages on ungrounded, conductive surfaces and objects. At certain points where high voltage conductors come close to grounded conductors (e.g., at feedline junctions or on the tower), dangerous electrical arcing or flashovers can occur. It is very important that you take the following steps to prevent damage to equipment or personnel due to RF fields: Use safety interlocks to de-energize transmitters if personnel open doors or panels accessing high field areas Place warning signs in any locations where high fields can occur Train personnel about the short-term and long-term hazards of RF radiation Physically block access to the area around the antenna system, feedline and tower Ground all exposed conductive surfaces or objects in high field areas The RF connection to the transmitter output can be a serious safety hazard. Connect a 50 Ω test load during installation and commissioning. It is recommended that a switch be used to automatically connect the transmitter to the antenna system without human contact with the transmitting conductors. Issue Page xvii

18 XR6/XR Troubleshooting Manual Safety interlocks The transmitter contains an electrical interlock, which is an external circuit that turns off the RF output if any of its switches are opened. Ac disconnect switch Safe operation of the transmitter requires an ac disconnect switch. Lock the ac disconnect switch in the disconnected (open) position during the installation process. Equipment safety Electrostatic protection The transmitter s systems are very rugged and resistant to damage. However, it is possible for damage to occur because of high voltage electrostatic discharges during servicing. Train all service personnel to ground themselves to bleed off any static charge before opening the transmitter or touching any exposed components. Provide a grounding wand or known ground (e.g., a grounded metal table) that personnel can use to discharge themselves. Surge protection Surge protection is recommended for your entire site. However, even if you do not use a surge protector on the service entrance to the site, you should install a surge protector in the transmitter s ac power feed to prevent over-voltage from entering the transmitter. Lightning protection The transmitter is designed to resist lightning strike damage. However, intense or repeated strikes could damage the transmitter. We recommend that you install lightning suppression on the antenna, tower and feedline to reduce the effect of lightning strikes on the transmitter itself (and to protect the rest of your site equipment and your personnel). For detailed information about lightning protection, see the Nautel Site Preparation Manual, available from your Nautel sales agent, or online from the Nautel website. Physical protection Consider physical hazards to equipment at your site, including the transmitter. Ensure that equipment is protected from weather (e.g., rain or flooding), even during extreme weather events. Place equipment so that it is not in the path of swinging doors or high-traffic areas. Do not allow wheeled items like office chairs or tables with wheels in the transmitter room, as these may damage equipment if accidentally pushed or knocked over. Do not place the transmitter under water pipes, drains, or sprinklers. Keep any equipment that generates heat, like the transmitter, away from flammable materials like ceiling panels, cubicle dividers, and curtains. Page xviii Issue

19 XR6/XR Troubleshooting Manual Earthquake protection If the transmitter site is in a region that experiences any noticeable earthquake activity, take steps to prevent the transmitter from shifting or rocking during an earthquake. Even during minor earthquakes, rocking or movement of the transmitter is likely to damage the feedline connection, and could even cause a catastrophic failure of the ac power feed into the transmitter. During larger earthquakes, the weight of the transmitter chassis could be hazardous to nearby equipment or personnel. Issue Page xix

21 XR6/XR Troubleshooting Manual Responding to alarms Section : Responding to alarms This section provides instructions you need when performing troubleshooting on the XR6/XR transmitter. This section includes the following topics: Corrective maintenance Electrostatic protection - see page - Identifying an alarm - see page -4 Responding to alarms - see page -8 Troubleshooting RF power modules - see page -4 If none of the procedures and alarms described in this section address your problem, contact Nautel for assistance. See Technical support on page ix. Corrective maintenance Corrective maintenance procedures consist of identifying and correcting defects or deficiencies that arise during transmitter operation. Local and/or remote alarm signals are generated when a malfunction occurs. If an alarm condition is caused by a malfunction in the RF power stage, the transmitter may maintain operation at a reduced RF output level. The nature of the fault and station policy will dictate whether an immediate maintenance response is necessary. Fault analysis and rectification may be conducted from three different levels, with a different technical competence level required for each: on-air troubleshooting, remote or local, and off-air troubleshooting. CAUTION: The transmitter contains many solid state devices that may be damaged if subjected to excessive heat or high voltage transients. Every effort must be taken to ensure that circuits are not overdriven or disconnected from their loads while turned on. On-air troubleshooting On-air troubleshooting can be performed from a remote location, or locally at the transmitter site. Issue Page -

22 XR6/XR Troubleshooting Manual Responding to alarms Remote troubleshooting Remote on-air troubleshooting consists of monitoring the transmitter's radiated signal using an on-air monitor, and observing the status of each remote fault alarm indicator. Information obtained from these sources should enable an operator to decide whether an alarm response may be deferred to a more convenient time, an immediate corrective action must be taken, or if a standby transmitter must be enabled (if one is available). It is recommended that the significance of remote indications, and the appropriate responses, be incorporated into a station's standard operating procedures. Refer to Identifying an alarm on page -4 to determine the remedial action required for a given fault. Local troubleshooting Local on-air troubleshooting consists of monitoring the transmitter's integral meters and fault alarm indicators. Analysis of this data will normally identify the type of fault, and in most cases will determine what corrective action must be taken. Refer to Identifying an alarm on page -4 to determine the remedial action required for a given fault. The power amplifier stage contains an integral modular reserve (IMR) feature. This feature permits the transmitter to operate at full RF output power level, from a standby RF power module, if purchased. Replacement of the defective RF power module may be deferred to a convenient time. A defective RF power module may be removed from the transmitter for servicing, while the transmitter is operating, provided that the conditions in the removal instructions detailed in Removing an RF power module on page -0 are met. Off-air troubleshooting Off-air troubleshooting must be performed when the replacement of a defective RF power amplifier module, or routine on-air calibration adjustments, will not restore operation. It is recommended that the transmitter s output be connected to a precision 50 Ω resistive dummy load (rated for at least the maximum transmitter power rating) before starting off-air troubleshooting procedures. If an appropriate dummy load is not available, troubleshooting for a majority of faults can be performed with RF power stage turned off. The transmitter may remain connected to its antenna system for these procedures. NOTE: Reduce the RF output level to a minimal value when troubleshooting faults in the power amplifier stage while the transmitter s RF output is connected to the antenna system. Page - Issue

23 XR6/XR Troubleshooting Manual Responding to alarms Electrostatic protection The transmitter's assemblies contain semiconductor devices that are susceptible to damage from electrostatic discharge. The following precautions must be observed when handling an assembly which contains these devices. CAUTION: Electrostatic energy is produced when two insulating materials are rubbed together. A person wearing rubber-soled shoes, walking across a nylon carpet or a waxed floor, can generate an extremely large electrostatic charge. This effect is magnified during periods of low humidity. Semiconductor devices such as integrated circuits, field-effect transistors, thyristors and Schottky diodes may be damaged by this high voltage unless adequate precautions are taken. Electrical discharging of personnel Personnel should be electrically discharged by a suitable grounding system (e.g., anti-static mats, grounding straps) when removing an assembly from the transmitter, and while handling the assembly for maintenance procedures. Handling/Storage An assembly should be placed in an anti-static bag when it is not installed in a host transmitter, or when it is not undergoing maintenance. Electronic components should be stored in anti-static materials. Tools/Test equipment Testing and maintenance equipment including soldering and unsoldering tools should be suitable for contact with static sensitive semiconductor devices. Stress current protection Every precaution should be taken to ensure the static sensitive semiconductor devices are protected from unnecessary stress current. This is achieved by ensuring that current is not flowing when an electrical connection is broken, and that voltages are not present on external control/monitoring circuits when they are connected.

24 XR6/XR Troubleshooting Manual Responding to alarms Identifying an alarm The best way to identify an alarm is by viewing the transmitter s front panel. There are several ways to use the front panel to identify the occurrence and origin of a fault: The system diagram (Figure.) is a flow diagram that indicates the operational status of various sections of the transmitter. If a lamp is on (red), a fault is occurring in the associated section of the transmitter. Figure.: The diagnostic display's meter screen has real-time meter indications (e.g., forward power) to assist in fault analysis. If an alarm occurs, a Status option appear s on the diagnostic display. Press the Status soft key to display all active faults. The diagnostic display's Events Log (see page - of the Operating and Maintenance Manual) provides a chronological list of faults and events to assist in fault diagnosis.. Determine the origin of the fault by noting which of the system diagram's lamps has turned on.. Attempt to clear the alarm from the Status screen by pressing the Reset button. If the alarm persists, it will not be cleared from the display.. Refer to Table. on page -5 for troubleshooting tips on the offending alarm(s), which may also reference replacement and subsequent re-calibration procedures. 4. If the troubleshooting and subsequent replacement of a suspect PWB or RF power module does not remove the fault condition, contact Nautel. NOTE: Before undertaking any troubleshooting, record all GUI meter readings. Then press the STATUS button - if present - on the GUI to see if any other alarms have been registered on the STATUS page. Record all alarms. Page -4 Issue

Connect a digital multimeter (set to measure dc) between TB- (EXT INTLK) of the remote interface PWB and ground.. If 4 V is present on TB-, the external interlock circuit is intact and the probable cause of the alarm is a defective monitoring circuit. Suspect the remote interface PWB or the control/ display PWB. 4. If 4 V is not present on TB-, measure the voltage between TB-7 (EXT +4V OUT) of remote interface PWB and ground, then between TB- (EXT INTLK) and ground. 5. If 4 V is present on TB- and TB-7, the external interlock circuit is open (normally caused by an open interlock switch). Low B+ voltage A Low B+ Voltage alarm is triggered when the B+ voltage falls below its factory-set threshold of about 50 V (B+ = 5 V), 50 V (B+ = 90 V) or 9 V (B+ = 5 V) for -phase XR6; 77 V (B+ = 0 V) or 9 V (B+ = 5 V) for -phase XR; 50 V (B+ = 5 V), 55 V (B+ = 96 V), 9 V (B+ = 5 V) or 55 V (B+ = 69 V) for -phase XR6; or 75 V (B+ = 0 V), 55 V (B+ = 96 V), 9 V (B+ = 5 V) or 55 V (B+ = 69 V) for -phase XR. Besides being noted on the status screen and the System Diagram, this alarm causes a shutback, the Softstart relays to open, and the fan and RF drive power supplies to turn off. Page -0 Issue

31 XR6/XR Troubleshooting Manual Responding to alarms Recovery from a Low B+ Voltage alarm is automatic when the B+ voltage rises above 65 V (B+ = 5 V), 60 V (B+ = 90 V) or 97 V (B+ = 5 V) for -phase XR6; 87 V (B+ = 0 V) or 97 V (B+ = 5 V) for -phase XR; 65 V (B+ = 5 V), 65 V (B+ = 96 V), 97 V (B+ = 5 V) or 59 V (B+ = 69 V) for -phase XR6; or 85 V (B+ = 0 V), 65 V (B+ = 96 V), 97 V (B+ = 5 V) or 59 V (B+ = 69 V) for -phase XR. The recovery process is the same as the power on process. NOTE: While RF power is enabled, the transmitter will automatically switch B+ voltages, as required, to maintain low distortion. If transmitter does not automatically recover from this alarm, the low B+ voltage is normally caused by low ac input voltage, improper primary taps on the power transformer, or a faulty rectifier assembly. Troubleshoot a Low B+ Voltage alarm as follows. WARNING: Lethal voltages exist in the power supply section of the transmitter.. Check the B+ voltage on the transmitter's diagnostic display s Meters screen. If it is less than 90% of desired, the ac power source voltage or power transformer tap selection is suspect.. Measure the ac input voltage and verify the power transformer is tapped as shown in Section, Installing the power transformer on page - of the XR6/XR Installation Manual.. If the transformer taps are correct, the monitoring circuit is suspect. Contact Nautel for troubleshooting information. High B+ voltage A High B+ Voltage alarm is reported when the B+ voltage goes above 80 V, but no other action is taken automatically. The alarm is normally caused by high ac input voltage, or incorrect primary taps on the power transformer. Troubleshoot a High B+ Voltage alarm as follows.. Check the B+ voltage on the transmitter's front panel. If the voltage is greater than 0% of desired, continue to Step.. Measure the ac input voltage and verify the main power transformer is tapped as shown in Section, Installing the power transformer on page - of the XR6/XR Installation Manual. Issue Page -

32 XR6/XR Troubleshooting Manual Responding to alarms. If the transformer taps are correct, the monitoring circuit is suspect. Contact Nautel for troubleshooting information. Fan P/S fault The 48 V power supply used for the fans is monitored and will report a fault if the voltage is outside the range of 48 V ± 0%.. Check for accompanying alarms in the Status screen. If there is a LVPS Fault, troubleshoot it first (see LVPS fault).. Measure the voltage between R48-LHS and ground on the distribution PWB. If it is within the range of 48 V ± 0%, recalibrate the 48 V supply to read the measured voltage (see Calibrating meters on page -9 of the Operating and Maintenance Manual). Otherwise replace power supply U. RF drive P/S fault The 6 V dc power supply used for the RF drive is monitored and will report a fault if the voltage is outside the range of 6 V ± 0%. The alarm could result from a fault in the RF drive power supply PWB, or faulty detection circuitry on the RF drive power supply PWB. Troubleshoot an RF Drive P/S Fault alarm as follows.. Check for accompanying alarms in the Status screen. If there is a LVPS Fault or Fan P/S Fault, troubleshoot it first (see LVPS fault or Fan P/S fault).. Measure the voltage between R50-RHS and ground on the distribution PWB. If it is outside the range of 6 V ± 0%, adjust the RF drive power supply PWB s VOLTAGE CONTROL potentiometer R to restore the voltage within its acceptable range.. If the input voltages are satisfactory, and the output cannot be adjusted to the required level, suspect the RF drive power supply PWB. 4. If the output voltage is within 6 V ± 0%, and the alarm persists, recalibrate the RF drive power supply to read the measured voltage (see Calibrating meters on page - of the Operating and Maintenance Manual). LVPS fault The 4 V, 5 V, -5 V and 5 V power supplies are monitored and will report a fault if the voltage is outside the range of ± 0%. One or more of these faults will result in only one LVPS Fault message on the Status screen, though each one would be reported by the Events Log. Page - Issue

33 XR6/XR Troubleshooting Manual Responding to alarms The alarm may be caused by a failure of the power supply, a fault in the detection circuitry on the exciter interface PWB, or a fault in the alarm circuit on the control/display PWB. Troubleshoot a LVPS Fault as follows:. On the control/display PWB, measure the following. If any readings are outside ± 0%, suspect a problem in the low voltage power supply. 5 V on TP9 5 V on TP 4 V on TP8-5 V on TP0. If the voltages in Step are correct, recalibrate each of the voltages to read the measured voltages (see Calibrating meters on page - of the Operating and Maintenance Manual).. Measure the voltage between R46-RHS and ground on the distribution PWB. If it is outside the range of 5 V ± 0%, replace power supply U4. VSWR alarm An output networks VSWR alarm indicates the reflected power is higher than normal. When VSWR reaches.5:, the transmitter will shutback the RF output power to prevent damage. An output network VSWR alarm can be caused by excessive reflected power, a fault in the forward/ reflected power probe assembly or a fault in the system control PWB's alarm circuitry. Troubleshoot a VSWR alarm as follows. NOTE: A VSWR alarm will always cause a SHUTBACK. If the problem occurs three times within five seconds, the transmitter shall be in CUTBACK mode to reduce RF output power until the VSWR alarm no longer exists.. Read the forward and reflected power from the diagnostic display s Meters screen. If the forward power has been reduced and the reflected power meter indicates reflected power, there may be a matching problem between antenna and transmitter (de-tuned load, arcing or poor bandwidth.. Perform a visual inspection of the antenna feed line and antenna and correct any obvious problems that can cause excessive reflected power. Issue Page -

34 XR6/XR Troubleshooting Manual Responding to alarms. If there are no obvious problems between transmitter and antenna, measure the voltage at TP and TP of the control/display PWB. If the voltage at TP is greater than 0% of TP, suspect the forward/reflected power probe. Otherwise suspect the control/display PWB. Total power limit This fail is triggered when the product of the B+ (dc) voltage and the dc current is greater than the limit set in software. For the XR6 the threshold is kva. For the XR the threshold is 5.5 kva. This fail causes an immediate cutback (power reduction), but not a shutback. Mod driver fail A This alarm is reported to the microcontroller only if exciter A is selected. If the exciter transfer function is set to auto then the microcontroller will attempt a changeover to exciter B. If it cannot or if the exciter transfer function is set to manual, then this fault will cause a shutback. This alarm indicates the PDM duty cycle of exciter A s modulator drive is too high. Try to reset the alarm. If the alarm persists, proceed to the steps listed in PDM drive fail. Mod driver fail B This alarm is reported to the microcontroller only if exciter B is selected. If the exciter transfer function is set to auto then the microcontroller will attempt a changeover to exciter A. If it cannot or if the exciter transfer function is set to manual, then this fault will cause a shutback. This alarm indicates the PDM duty cycle of exciter B s modulator drive is too high. Try to reset the alarm. If the alarm persists, proceed to the steps listed in PDM drive fail. PDM drive fail This fault indicates that the PDM drive is inoperative. If the exciter transfer function is set to auto, then the microcontroller will attempt an exciter changeover to the other side. If it cannot complete an exciter changeover, or if the exciter transfer function is set to manual, then this fault will cause a shutback. A PDM Drive Fail alarm indicates that the PDM drive signal s duty cycle is too low (pulse width too narrow). It may be caused by a fault on the interphase PDM driver PWB or the control display PWB's alarm circuitry. Troubleshoot a PDM Drive Fail alarm as follows:. The PDM Drive Fail alarm initiates an automatic exciter changeover to the standby exciter. To troubleshoot a defective exciter circuit, set changeover to manual as detailed in Changing automation settings in the Operating and Maintenance Manual. Page -4 Issue

35 XR6/XR Troubleshooting Manual Responding to alarms. If the transmitter successfully switched to the standby exciter, suspect the main exciter's interphase PDM driver PWB.. Use an oscilloscope to measure the voltage at TP6 on the interphase PDM driver PWB. The indication should have a dc offset of.4 V ± 0%. If not suspect the remote interface PWB or the IBOC/DRM exciter if you are operating in all-digital (HD) mode. 4. Measure the dc voltage at TP of the interphase PDM driver PWB. If the voltage is either 0 V (and transmitter not shut back) or 5 V, suspect the control/display PWB. 5. Use an oscilloscope to measure TP of the interphase PDM driver PWB. The signal should be a square wave at the transmitter s f PDM frequency (nominal 0 khz). If not, suspect the RF synthesizer PWB. 6. Measure the dc voltage at TP on the interphase PDM driver PWB. The voltage should be the B+ voltage multipled by 0.0 ± 0%. If not, suspect the wiring to the B+ distribution PWB or the exciter interface PWB. 7. If no faults were found in the previous steps, suspect the control/display PWB. Auto changeover This event is caused by a fault in the active exciter with the Auto Changeover function enabled. Faults that cause exciter changeovers are: Mod Driver Fail A/B, RF Driver Fail and PDM Drive Fail. This event triggers the Changeover LED to light, and it will remain lit until manually cleared. No further auto changeovers are possible until the alarm is cleared. The alarm can be cleared remotely by re-selecting the active exciter. The alarm can be cleared locally by use of the Preset screen. An Auto Changeover alarm indicates that the standby exciter is operating and that the transmitter has switched from main exciter to standby exciter. The Auto Changeover alarm may be caused by a fault in the transmitter that initiated an automatic exciter changeover, or a fault in the control/display PWB's microprocessor or alarm circuit. Troubleshoot the Auto Changeover alarm as follows:. Check the Events Log to determine the possible cause of the exciter changeover.. Troubleshoot any alarms recorded in the Events Log to determine the cause of the exciter changeover. Issue Page -5

36 XR6/XR Troubleshooting Manual Responding to alarms RF driver fail This fault indicates a problem with the RF drive on the current exciter. If the exciter transfer function is set to auto then the microcontroller will attempt an exciter changeover to the standby exciter. If it cannot complete an exciter changeover, or if the exciter transfer function is set to manual, then this fault will cause a shutback. An RF Driver Fail alarm indicates an incorrect voltage waveform in the RF drive buffer PWB. The alarm could result from a failure in the RF drive buffer PWB, RF synthesizer PWB, or in the control/ display PWB's alarm circuitry. Troubleshoot an RF Driver Fail alarm as follows:. The RF Driver Fail alarm initiates an automatic exciter changeover to the standby exciter. To troubleshoot a defective exciter circuit, set changeover to manual as detailed in Changing automation settings in the Operating and Maintenance Manual.. Use an oscilloscope to measure TP7 of the RF synthesizer PWB. The signal should be a 5 volt peak-to-peak square wave at the carrier frequency. If the signal is present, suspect the RF drive buffer PWB. Otherwise suspect the RF synthesizer PWB.. Use an oscilloscope to measure TP of the RF drive buffer PWB. The signal should be a 5 volt peak-to-peak square wave at the carrier frequency. If the signal is present, suspect the RF drive buffer PWB. 4. Measure the dc voltage at TP of the RF drive buffer PWB. If the voltage is less than 0.6 V, suspect the control/display PWB or transistor Q on the RF drive buffer PWB. Cutback level (-8) Should there be three shutbacks within five seconds, the transmitter will enter a power reduction mode called a cutback. There are eight levels of cutbacks, the last being a reduction to no forward power whatsoever. At any given cutback level, there is a predefined time limit that must expire before the cutback level is reduced to the previous level. If there are no further cutbacks, this process continues until Level 0 (normal) is reached. The cutback recovery process can be overridden by adjusting the power (up or down), or by pressing Reset on the Status screen. Page -6 Issue

37 XR6/XR Troubleshooting Manual Responding to alarms A Cutback Level (-8) status indicates that several shutback alarms (at least three shutbacks in five seconds) have occurred. A cutback alarm may be triggered by a fault in the transmitter, large VSWR, or a fault in the control/display PWB's microprocessor or alarm circuitry. Troubleshoot a cutback alarm as follows:. Read the RF output power level on the RF KILOWATTS meter on the transmitter's front panel.. Press/release the Control - Power Increase switch to clear the cutback alarm and to restore the preset power level. If the fault persists, the output power will automatically cut back again. Observe the Events Log and note which alarm is causing shutback. Refer to the appropriate troubleshooting paragraph in this section. Ext. PDM inhibit The external PDM inhibit is wired to the remote interface PWB. An Ext. PDM Inhibit alarm indicates that an external PDM inhibit command is present. The alarm could be caused by an short circuit in the external wiring path to the remote control PWB, a fault in the switching circuitry on the remote interface PWB, or a fault in the alarm circuitry on the control/ display PWB. Troubleshoot an Ext. PDM Inhibit alarm as follows:. If E9 is between pins and, verify the dc voltage between TB-6 and ground on the remote interface PWB is approximately 4 V. This signifies there is no external PDM inhibit command.. If E9 is between pins and, verify the dc voltage between TB- and TB-6 on the remote interface PWB is 0 V. This signifies there is no external PDM inhibit command.. If the conditions in Step and Step are met, suspect the remote interface PWB or the control/display PWB. Int. serial fail This alarm indicates that there is no communication with the remote interface PWB. This alarm is triggered if two seconds go by without acknowledgement from the remote interface PWB of the control/display PWB's request for information. (The control/display PWB requests updates from the remote interface PWB every 00 ms).. Check the cable between connector P (mates with J of the control/display PWB) and connector P5 (mates with J of the remote interface PWB). If the cable and connections are intact, suspect a problem with the control/dispaly PWB or remote interface PWB. Issue Page -7

38 XR6/XR Troubleshooting Manual Responding to alarms Mod. protection This fail is reported from the remote interface PWB. The exciter monitors a sample of the RF output and conditions the modulator outputs if the RF drive current becomes great enough to damage the modulators. A Mod Protection alarm may occur from overdriving the transmitter (high output power, high modulation depth, or very low modulating frequency), a fault in the control/display PWB's alarm circuitry, or a fault in the remote interface PWB's circuitry. Troubleshoot a Mod Protection alarm as follows:. Examine the operating conditions under which the alarm occurred. A Mod Protection alarm may be initiated if the transmitter is running at rated power with high modulation at a low modulating frequency. If these conditions were present at the time of the alarm, adjust the modulating audio low frequency roll off to 0 Hz.. Use an oscilloscope to view TP6 on the interphase PDM driver PWB. If the transmitter is operating at rated power and the audio is clipped (see Figure.), complete Modulation Peak Limiting on page 5-5 of the XR6/XR Operating and Maintenance Manual. Figure.: Chopper Control Waveform Audio = 0Hz (AC Coupled) Softstart active The softstart relays are initially open for.6 seconds when the transmitter s power is first turned on. The software should close the relays after.6 seconds and clear this alarm. While active, this alarm causes a shutback and inhibits the RF drive and fan power supplies. The Softstart Active alarm should be accompanied by a B+ Relay Open alarm. Page -8 Issue

39 XR6/XR Troubleshooting Manual Responding to alarms SoftStart OverTemp The software keeps track of the calculated temperature of the softstart relays and triggers this fault if that value is greater than 50 C. While this fault is on, RF power is not available. The temperature is assumed to rise 0 C for each cold start and 0 C for each warm start. The temperature falls exponentially as calculated by the software. The temperature estimate decays over time. When the temperature falls below 50 C, the alarm clears on its own. CAUTION: Performing a warm or cold start while the SoftStart OverTemp fail is active is strongly discouraged. Low backup battery The voltage of the backup battery has fallen below an acceptable level. Replace the battery on XBT of the control/display PWB (AA). This battery should be replaced while ac power is on. Should ac power fail without adequate battery power, then the Events Log and Real Time Clock will be cleared. The fault may be caused by a weak battery, or a fault in the detection or alarm circuitry on the control/display PWB. If the alarm remains after the battery is replaced, suspect the control/display PWB circuitry. NOTE: Batteries should be replaced once a year or as soon as weak batteries cause the Low Backup Battery alarm to turn on. This helps prevent chemical dripping from an old battery, and to ensure adequate backup voltage for the control/display PWB's microcontroller when the ac power is turned off. Issue Page -9

44 XR6/XR Troubleshooting Manual Responding to alarms Troubleshooting RF power modules Maintenance philosophy Independent testing of an RF power module at the normal B+ voltage and RF power ratings requires specialized test equipment that is not available outside of the factory. Therefore, an optional RF power module test cable can be provided for testing and troubleshooting an RF power module outside of the transmitter. An RF power module may be connected to the transmitter's integral RF power module test circuitry via a test cable, and serviced outside of the transmitter on an external work surface. In this test setup, the B+ voltage is restricted to 48 V. This voltage is not considered hazardous to maintainers, but can produce minor skin burns. Also, the resultant, low-level, RF output is applied to a test load and does not contribute to the transmitter's RF output. NOTE: Host transmitters have a built-in RF power module test capability. If the transmitter has more than one RF power module, an RF power module may be tested without affecting the transmitter's on-air status. Special Tools and Test Equipment The following test equipment and cables are required to troubleshoot an RF power module. Power Module Test Kit The power module test kit (Nautel part # 0-505) is required to use the transmitter s integral test circuits. It is optionally provided by, or available from, Nautel. It contains: RF power module test cable (Nautel part # 0-500). RF power module test load (Nautel part # ). Test Equipment Minimum required test equipment: A digital multimeter. A dual-channel oscilloscope with two 0X probes. Page -4 Issue

45 XR6/XR Troubleshooting Manual Responding to alarms Special Tools Required special tools: NOTE: If the digital multimeter does not have diode checking capability, a dc voltage source (9 V dc battery) is required to turn on MOSFETs during troubleshooting procedures. A torque wrench with a torque range of 0.0 to.6 N-m (0-0 in.-lbs). Required for installing MOSFET attaching hardware. A 5 mm (97 in.), hex, thin-walled socket, with the same size drive as the torque wrench. The outside diameter of the socket must be less than 7 mm (0.75 in.). A 5 mm (97 in., hex nut driver. The diameter of the outside wall must be less than 7 mm (0.75 in.). A.5 mm (0.098 in.), hex screw driver (Nautel part # HAZ65), included in the ancillary kit. Electrostatic Precautions The RF power module contains semiconductor devices that are susceptible to damage from electrostatic discharge. Be sure to follow the electrostatic precautions in Electrostatic protection on page - at all times. Fault Alarm Response If possible, determine which LEDs on the front of the RF power module were turned on prior to its removal from the transmitter. If it is not known which front panel LEDs were on, or if none were on, proceed to Preparation for testing on page -6. If the RF Drive LED was on, connect the module to the test cable (see Test cable connection on page -9) and perform the RF drive tuning check on page -5. If the problem persists after tuning, suspect the module s RF drive control PWB. If the Temp/Inhibit LED was on, connect the module to the test cable (see Test cable connection on page -9) and perform the Temp/inhibit check on page -5. If one or more Block LEDs were on, proceed to Preparation for testing on page -6. Issue Page -5

46 XR6/XR Troubleshooting Manual Responding to alarms Preparation for testing. Follow the procedure in Removing an RF power module on page -0 to remove the power module from the transmitter.. Place the RF power module on a suitable work surface in close proximity to the transmitter's RF power module test circuit, so that the RF power module test cable can reach the power module.. Remove all seven screws from the RF power module's left and right covers. Remove covers. Resistance measurements Prior to connecting an RF power module to the test circuit, complete the following resistance measurements for each RF power block. Refer to Table. and Figures MD-4 and MD-5 in the Mechanical Drawings section to identify the assemblies associated with a specific RF power block. Table.: Assemblies Associated with Each RF Power Block RF Power Block B+ Fuse PDM Fuse Modulator Assembly Modulator Filter PA Input/Output PWB RF Amplifier A A4F A4F A5 A6 A8 A0/A B A4F4 A4F5 A4 A7 A9 A/A C A4F6 A4F7 A6 A7 A9 A/A D A4F8 A4F9 A5 A8 A0 A/A4. Remove fuse A4F from its holder and measure its resistance using the digital multimeter. A blown fuse will measure an open circuit.. Repeat Step for the remaining B+ fuses (A4F4, A4F6 and A4F8), PDM fuses (A4F, A4F5, A4F7 and A4F9) and the +5 V dc fuse (A4F), noting which fuses are good and which are blown. Blown fuses indicate a fault in the associated power block.. Also check the RF drive B+ fuse (F) on the RF drive control PWB (A). A blown AF fuse indicates a fault in the RF drive section of the RF drive control (PWB). Page -6 Issue

47 XR6/XR Troubleshooting Manual Responding to alarms PA volts to ground impedance Measure impedance between the PA volts and ground for each RF power block:. Measure resistance between terminal H (PA volts input) of each PA input/output PWB and ground, using a digital multimeter.. Each of the resistance measurements in Step should be a nominal 77 kω. If all measurements are satisfactory, proceed to PA volts to B+ impedance on page -8.. If any resistance measurement in Step is less than 77 kω, disconnect connector P from J of the RF drive control PWB and repeat the resistance measurement. 4. Each resistance measurement in Step should be open circuit. If they are now satisfactory, an impedance problem exists in the RF drive control PWB's PA volts circuit. CAUTION: The heat sinks of modulator assemblies and RF amplifiers are coated with a film of thermal compound. Use care to ensure the film does not become contaminated with foreign particles. When installing an assembly, visually inspect the mating surfaces of its heat sink and the module's chassis. Ensure both surfaces are coated with a thin film of thermal compound. Ensure foreign particles that may affect thermal transfer are not embedded in the compound. 5. If a resistance measurement in Step 4 is not satisfactory, sequentially remove the modulator assembly and both RF amplifiers associated with the suspect RF power block (see Table. on page -6) and note the resistance measurement as each assembly is removed. If a resistance measurement indicates an open circuit after the removal of an assembly, do not remove any additional assemblies. Assume the last assembly removed is defective. Reinstall other removed assemblies (if any) for the RF power block being tested and note the resistance measurement as each assembly is installed. If the resistance measurement is unacceptable after the installation of an assembly, assume the assembly is defective and replace it (see Modulator assembly replacement on page -46 or RF amplifier assembly replacement on page -47). 6. Reinstall removed assemblies, using repaired or serviceable replacement assemblies. If connector P was disconnected from J of the RF drive control PWB, reconnect it. Issue Page -7

48 XR6/XR Troubleshooting Manual Responding to alarms 7. Restart impedance checks at Step. PA volts to B+ impedance Measure impedance between the B+ volts input and the PA volts output for each RF power block:. Measure the resistance between terminal H (PA volts) of each PA input/output PWB and its associated B+ fuse.. Each resistance measurement in Step should be about 0 kω with the red meter lead on the H terminal, and about 400 kω with the black meter lead on the H terminal. If all measurements are satisfactory, proceed to Functional test procedures on page -8.. If any resistance measurement in Step is greater than.0 MΩ, assume the modulator assembly associated with the RF power block is defective (contains defective MOSFETs). Replace the suspect modulator assembly (see Modulator assembly replacement on page - 46). 4. Reinstall removed modulator assemblies, using serviceable replacement assemblies. 5. Restart impedance checks at Step. PA output to ground impedance Using a multimeter set to measure ohms, measure the resistance from the C terminal (+ or -) to ground, and the G terminal (+ or -) to ground, on all four PA input/output PWBs. If the module is cold, the resistance should measure about MΩ or more. If the reading is near 0 Ω, the PA being measured contains shorted FETs and must be replaced or repaired. Replace the suspect PA assembly (see RF amplifier assembly replacement on page -47). Functional test procedures Perform a functional test to verify the status of suspect or repaired RF power modules as follows:. Verify that all assemblies suspected of being defective based on the status of the front panel Alarms lamps, or by failing an impedance test given in Resistance measurements on page -6 have been replaced with a serviceable assembly.. Verify that all of the RF power module's electrical assemblies are properly installed, and all mating connectors are properly connected. Page -8 Issue

49 XR6/XR Troubleshooting Manual Responding to alarms Test cable connection Connect the RF power module to be tested to the transmitter's test circuit as follows: WARNING: Although the module under test is connected to low-level voltages, its rf output can still exceed 500 volts peak-to-peak. This voltage can cause painful rf burns. Avoid contact with the test load while the module is operating on the test circuit.. Connect the test load (Nautel part # ) to J of the RF power module. J is the upper connector on the rear of the power module (see Figure.4 on page -).. Connect P4 of the test cable (Nautel part # 0-500) to J of the RF power module to be tested, noting that J is the lower connector on the rear of the power module.. Connect P of the test cable to J5 (RF DRIVE/TEST) of the transmitter's RF drive buffer PWB (A5). 4. Connect P of the test cable to J on the transmitter s distribution PWB (A). NOTE: The test circuit's B+ supply (48 V) is protected by a thermistor (PTC). Measure the dc voltage on modulator fuse A4F once the test cable's P is connected to the module's J connector. If there is a shorted modulator installed in the module, the voltage reading will be near 0 V. Repeat all of the checks in Resistance measurements on page -6. The test circuit s RF drive supply is protected by a thermistor (PTC). Measure the dc voltage on RF drive control PWB fuse AF once the test cable s P is connected to the module s J connector. If there is a problem with the RF drive section of the RF drive control PWB, the voltage reading will be near 0 V. Repeat all of the checks in Resistance measurements on page Connect P of the test cable to the module's J connector, noting that J is located on the bottom of the module near its front. The module will have to be placed on a table to allow access to J. Ignore all alarm indications at this time. Issue Page -9

50 XR6/XR Troubleshooting Manual Responding to alarms NOTE: The RF power module may be connected to the transmitter s test circuit without turning the transmitter off or interrupting its on-air operation. The host transmitter must be turned on and its RF power stage must be enabled (its RF On LED must be on) for dc voltages to be applied to the RF power module. Sufficient output power must be provided to allow the PDM signals, generated by the transmitter, to drive the module under test. Use an oscilloscope to measure the duty cycle on TP7 of the interphase PDM driver PWB. Increase power until the duty cycle is above 0%. The RF power module's Block (A, B, C and D) alarm LEDs will be on when the module is connected to the test circuit. This is normal operation and does not mean the modulators have failed. This false alarm is an indication that the modulator failure detector circuit is functioning, since the reduced test B+ voltage (48 V dc) is seen to be a modulator failure. 6. Verify the test circuit is applying the dc voltages required by the RF power module. Use a multimeter to measure the dc voltages as tabulated in Table.4. Table.4: Dc Voltages Provided By Transmitter Test Point A4-F AL AL AL Voltage 48 V 4 V 5 V 5 V 7. Verify the alarm circuitry is operating properly by pressing Reset in the Status screen of the host transmitter s GUI. The Temp/Inhibit alarm should turn off, and the Block alarms should remain on. Then press the power module's Inhibit button and the Temp/Inhibit alarm should turn on. If the Temp/Inhibit alarm LED will not turn off and on as indicated, there is a fault with the alarm circuitry on the RF drive control PWB. This fault must be repaired before proceeding. If the RF Drive alarm LED remains on after Reset is pressed, proceed to RF drive tuning Page -0 Issue

51 XR6/XR Troubleshooting Manual Responding to alarms check on page -5 to attempt tuning of the RF drive. If the RF Drive LED remains on after tuning, suspect the RF drive control PWB. NOTE: If the test circuits B+ supply fails when the temporary jumper is installed in Step 8, suspect a failed power amplifier (NAA5A). Thermistor RT on the distribution PWB will limit the current available to the test circuit resulting in the 48 V going to near 0 V. Repeat the checks in PA output to ground impedance on page -8 to determine if there are any shorted PAs. 8. Temporarily latch all of the protection/alarm circuits in their reset state by connecting a jumper between ground (TP or TP4) and TP on the RF drive control PWB. 9. All of the alarm LEDs, including the Block (A, B, C and D) alarm LEDs, shall turn off. Modulator checks Measure the filtered PA volts output of each modulator, which is controlled by the on-time of the PDM input. The PA volts for each RF power block should be a percentage of the B+ (48 V) being applied to the associated modulator assembly. The output voltage of all four modulators should be within.5 V of each other. If one voltage measures low or high, suspect the associated modulator. NOTE: Sufficient output power must be provided to allow the PDM signals, generated by the transmitter, to drive the module under test. Use an oscilloscope to measure the duty cycle on TP7 of the interphase PDM driver PWB. Increase power until the duty cycle is above 0%. The PDM input is a square wave with nominally equal on and off times. If the on time is 50% of each cycle, the PA volts would be 4 V (50% of the 48 V test B+ voltage).. Measure the dc voltage between terminal H of each PA input/output PWB and ground, using a digital multimeter.. The voltage level depends on the PDM level being generated by the transmitter. If all measurements are satisfactory, proceed to RF amplifier checks on page -.. If any voltage measurement in Step is not satisfactory, assume the modulator assembly for the RF power block associated with the unsatisfactory measurement is defective. Replace the suspect modulator assembly (see Modulator assembly replacement on page -46). Issue Page -

The indication on the oscilloscope should be a ringing square wave at carrier frequency with a peak-to-peak voltage of about 400 volts. The indication on both traces (A and B) should be almost identical. If they are not almost identical, or the peak-to-peak voltage is not about 400 volts, suspect a problem with one or more PAs. CAUTION: DO NOT connect the oscilloscope test probes between the (+) terminations for the C and G outputs of a PA input/output PWB. If the oscilloscope probe's ground lead, which is usually referenced to ground, is connected to either the (+) or (-) C or G outputs, irreversible damage to the MOSFETs in the PAs can occur. The probe's ground lead MUST only be connected to the module's chassis.. To check the output of individual PAs, connect one scope probe to the C (+) and the probe's ground lead to chassis, connect the oscilloscope other probe to the C (-) and the probe's ground to chassis on the PA input/output PWB for the suspect PA. Both waveforms shall be a rectangular wave, 0 to 4 V dc (assuming 50% duty cycle; actual peak voltage is 48 V x duty cycle), with channel A phase shifted 80 0 from channel B. 4. Repeat this procedure for the G terminals on the PA input/output PWB. Connect one scope probe to the G (+) and the probe's ground lead to chassis. Connect the oscilloscope s other probe to the G (-) on the PA input/output PWB for the suspect PA. Both waveforms shall be a rectangular wave, 0 to 4 V dc (assuming 50% duty cycle; actual peak voltage is 48 V x duty cycle), with channel A phase shifted 80 0 from channel B. Page - Issue

If any C or G waveform is not satisfactory (rectangular wave, 0 to 4 V, assuming 50% duty cycle), the PA associated with the unsatisfactory waveform is defective and must be replaced (see RF amplifier assembly replacement on page -47). 6. Install a repaired or serviceable replacement PA in each vacant PA position, and then restart the tests at Step. WARNING: The power module must be removed from the transmitter's test circuit before any sub-assembly is installed or removed from the power module. Failure to do so can result in damage to the electronic components in the power module. It is important to remove the power module from the test circuit by following Step 7 through Step in the order they are listed to avoid personal injury and damage to the power module.

Control/display PWB (NAPC47D) See electrical schematics Figures SD-5 through SD-8. Carrier reference voltage The Carrier Ref (A) output (J7-8) is applied to the interphase PDM driver PWB of each exciter to generate the PDM drive pulse that ultimately controls the RF output of the transmitter. DAC U, in conjunction with microcontroller U, establishes a dc reference voltage for the Carrier Ref output. The voltage is buffered through operational amplifier U7B and associated components. Alarm threshold circuits Certain parameters that are monitored by the control/display PWB can initiate an alarm indication and appropriate transmitter control if an out of tolerance condition occurs.

70 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Ac supply voltage The Ac Power input (J4-) is an unregulated dc voltage that is proportional to the ac source. The input is filtered and compared to the low ac ref fault threshold on operational amplifier U4C. If the Ac Power voltage is below this threshold, the ac low signals switch to 0 V. The Carrier Ref (A) output clamps to 0 V and the Shutback (A) (J7-) and (B) (J7-) outputs switch to 0 V and inhibit the exciter's modulator drive. The transmitter's RF output turns off (shuts back) and remains off until the ac power returns to an acceptable voltage. The system diagram's AC Mains lamp displays a fault condition. An Ac Sample signal is applied to ADC U9 for application to the diagnostic display. Reflected power monitor The Refld Pwr Sample input (J-5) is a dc voltage that is proportional to the reflected power at the transmitter's output. The input is filtered and buffered by operational amplifier UB and associated components, and then applied to the remote interface PWB via the external serial interface (microcontroller U). The signal is also compared to a pre-determined refld pwr shtbk ref fault threshold on operational amplifier U4A. When the peak reflected power exceeds a.5: VSWR (based on rated forward power), the refld pwr sample input exceeds the fault threshold and the refld_pwr_shutback signal switches to 5 V. The Carrier Ref (A) output clamps to 0 V and the Shutback (A) (J7-) and (B) (J7 ) outputs switch to 0 V and inhibit the exciter's modulator drive. A clock pulse is also applied to an alarm count/cutback circuit in complex programmable logic device (CPLD) U8. The RF output is instantly shut back (turn off). The system diagram's Output Network lamp displays a fault condition. A Refld Pwr Sample signal is applied to ADC U9 for application to the front panel's diagnostic display. Turning off the RF output reduces the refld pwr sample input to 0 V. The Carrier Ref (A) output is restored to its pre-shutback levels, the Shutback A and B outputs return to open collector, and the RF output is restored at an exponential rate. If the fault threshold is exceeded before the pre-set power level is reached, the shutback cycle is repeated. If three or more shutback cycle clock pulses are applied within any five second period, the Carrier Ref (A) output is cut back (reduced) until the carrier level is cut back to a level that results in an acceptable reflected power. When the transmitter enters cutback mode, the system diagram's Output Network lamp flashes on and off. When the refld pwr sample input returns to or is maintained at a level which is less than the fault threshold, the Shutback outputs returns to open collector but the system diagram's Output Network lamp continues to display a fault as a maintenance aid. The lamp remains on until reset by the diagnostic display menu. Sample monitoring circuits Various parameters are applied to the control/display PWB for local (via the front panel's diagnostic display) and/or external (via the remote interface PWB) monitoring. In most cases, these parameters also have associated alarm detection circuitry, but it is not resident on the control/display PWB. Page - Issue

PDM drive The PDM (A) (J4-9) and PDM (B) (J4-7) inputs are pulses which represent the PDM signal applied to sides A and B of the RF power stage.

Forward power The Fwd Pwr Sample input (J-) is a dc voltage which represents the forward power at the transmitter's RF output. The input is filtered through operational amplifier UD and associated components. A fwd_pwr_sample signal is applied to ADC U9 for application to the front panel's diagnostic display. The fwd_pwr_sample input is also applied to the remote interface PWB via the external serial interface (microcontroller U). RF drive voltage sample The RF Dr Volts Sample input (J4-9) is a dc voltage which represents the voltage supplied by the RF drive power supply.

72 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Cabinet temperature Low voltage temperature sensor U5 provides a dc voltage (between 0 and 5 V) which represents the ambient cabinet temperature. This voltage is buffered by operational amplifier U8A and associated components and applied to ADC U for application to the front panel's diagnostic display. Microcontroller Microcontroller IC U interfaces between the diagnostic display and its associated soft-keys. It controls the level of the Carrier Ref signals (see Carrier reference voltage on page -), which ultimately determines the forward power level of the transmitter. It also acts as an internal and external serial interface for transmitter alarm and status signals. CPLD Complex programmable logic device (CPLD) U8 continuously reads digital inputs for all transmitter alarm events. It is programmed to perform root cause detection of a fault as well as high-speed fault protection. Depending on the nature of the fault, the CPLD generates transmitter Shutback outputs (J7- and J7-) or various digital control/inhibit signals via a parallel data bus. RF synthesizer PWB (NAPE70C) See electrical schematics Figures SD- and SD-. Microprocessor The microprocessor consists of an 87C5 integrated circuit (U4) which is clocked at the system oscillator frequency ( MHz). Firmware resides in U4's internal four kilobytes of EPROM memory. The microprocessor's functions are to generate control information for the DDS circuit, generate control information for the N divider circuit, and provide control signals to all power modules during transmitter tuning. DDS control information The RF carrier frequency is set using five binary coded decimal (BCD) switches (S through S5). When a current sink to ground is applied at the Reset DDS input, or during turn on, the microprocessor monitors these switches and outputs the appropriate 48-bit value to the DDS frequency tuning word # register. The 48-bit value is written in six consecutive bytes to the DDS's six internal registers. The WRB/SCLK signal is enabled on each write cycle. Page -4 Issue

73 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions N divider control information The 4f c /B frequency is divided by an 'N' factor, to provide f PDM output frequency between 6 khz and 4 khz (when E is set in LOW PDM mode) or between 45 khz and 76 khz (when E is set in HIGH PDM mode) (see N divider on page -7). E should be set to HIGH PDM mode when used in an XR6/XR transmitter. The microprocessor determines the value of N and outputs the information at pins,, 4, 5, 6 and 7. The N divider uses this information as the N dividing factor. Direct digital synthesizer The direct digital synthesizer consists of integrated circuit U5 (AD9855Q) and associated components. It generates a frequency of 4f c based on information provided by microprocessor U4 (see Microprocessor on page -4). Integrated circuit U5 is a CMOS, numerically controlled oscillator with a 48-bit phase accumulator and -bit digital-to-analog converter (DAC). The phase accumulator, responsible for generating an output frequency is presented with a 48-bit value from the Frequency Tuning Word registers whose contents determine the FTW as follows: FTW = (Desired Output Frequency x 48 )/SYSCLK The 0 MHz clock input, coupled with U5's internal programmable reference clock multiplier, results in a system clock of 50 MHz (i.e. SYSCLK = 50 MHz). The -bit output from the phase accumulator is input to the DAC, which outputs a stepped sine wave at a frequency of 4f c which is low-pass filtered to remove high frequency components. Low pass filter A low-pass filter comprised of C, L and C removes the high frequency images present in the DDS output signal. The output is a sine wave at a frequency of 4f c. Digitizer The output of the low-pass filter is connected to a digitizer circuit consisting of transistor Q4, inverter U0:B and associated components. U0:B's output is a square wave at frequency of 4f c which is applied to a divide-by-4 circuit and to the N divider circuit. IPM correction The incidental phase modulation IPM Correction circuit forms part of a dynamic loop that monitors the IPM compensation input and compensates for any incidental phase modulation caused by the host transmitter's RF power stages. Issue Page -5

74 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Virtual capacitor Complementary transistor pair U:A and U:B, capacitors C50 through C5 and associated components form a virtual capacitor, the value of which is determined by current flow through U:A. Amplitude and phase of the IPM compensation input controls gain of U:A, thereby controlling current flow in the transistor and ultimately the virtual capacitance of the IPM correction circuit. IPM BALance potentiometer (R4) is adjusted, when the RF synthesizer PWB is in a transmitter, for optimum correction of any incidental phase modulation. Switch elements S6:, S6: and S6: provide the proper capacitance depending on the carrier frequency. See the table below to determine the settings for the switch elements. f c (khz) Capacitance (pf) S6 Switch Settings = switch open; = switch closed IPM correction enable The position of switch element S6:4 determines when the IPM correction circuit is enabled or disabled. The IPM correction circuit should be disabled (switch S6:4 set to CLOSED position) when used in an XR6/XR transmitter. Note: It may be desirable to disable the IPM correction circuit for some testing purposes. Return the switch to its regular position during normal operation. Waveform symmetry RF DRIVE SYMMETRY potentiometer R - which allows for minimizing of second harmonic levels - is adjusted for an RF drive output waveform which is a symmetrical square wave (50% duty cycle), as measured at the RF DRIVE (TEST) output (J5) of the RF drive buffer PWB. The position of SYMMETRY ADJust shorting jumper E6 determines when the RF drive symmetry circuit is enabled or disabled. E6 should be installed in the ENABLE position (shorting pins and ) when used in an XR6/XR transmitter. Page -6 Issue

75 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Balanced drive The balanced drive buffer is a switching circuit that ensures the rise and fall times of its output square wave are minimal. The f c signal is a 5 V peak-to-peak square wave that is the low level RF drive signal for the RF power stage of the transmitter. Balanced drive matching Provision is made for several different values on the balanced drive output, depending on the host transmitter's requirements. The positioning of shorting shunt post E5 on seven-position header XE5 can be changed to choose between different capacitor and resistor values. E5 should be installed in the D position (shorting pins 7 and 8) for an XR6/XR transmitter. N divider The N divider circuit is a cascade counter made up of integrated circuits U6, U7, and inverters U8:A and U8:F. The 4f c /B signal is divided by N, to provide a f PDM frequency which is between 6 khz and 4 khz (when E is set in LOW PDM mode) or between 45 khz and 76 khz (when E is set in HIGH PDM mode). E should be set to HIGH PDM mode when used in an XR6/XR transmitter. The value of N is supplied by microprocessor U4 (see N divider control information on page -5). The f PDM output, which is nominal 0-4 V peak pulses, is applied to the transmitter's pulse duration modulation (PDM) generation circuit, and ultimately determines the PDM frequency. RF drive source selection The RF drive source may be provided by the integral numerically controlled oscillator, an external RF generator at f c or a 0 MHz reference. The positioning of shorting shunt posts E, E and E4 determines which RF drive source is selected. Internal f c source When the integral numerically controlled oscillator's output is to be used as the RF drive source, the shorting shunt posts must be configured as follows: - E in INT position (pins and shorted) - E in INT position (pins and shorted) - E4 in INT position (pins and shorted) External f c source When an externally generated carrier frequency is to be used as the RF drive source, the shorting shunt posts must be configured as follows: Issue Page -7

76 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions - E in INT position (pins and shorted) - E in INT position (pins and shorted) - E4 in EXT position (pins and shorted) The applied RF must be precisely the carrier frequency (f c ) and its peak-to-peak voltage (sine or square wave) must be between 5.0 V and.0 V. External 0 mhz source An external 0 MHz can be used for synchronization (i.e., GPS lock). When an external 0 MHz signal is to be used as the RF drive source, the shorting shunt posts must be configured as follows: - E in EXT position (pins and shorted) - E in EXT position (pins and shorted) - E4 in INT position (pins and shorted) The applied RF must be precisely 0.00 MHz and its peak-to-peak voltage (sine or square wave) must be between. V and 8.0 V Interphase PDM driver PWB (NAPM0B) See electrical schematic Figure SD-4. Carrier level control The carrier level control circuit consists of U6, UA, UD, UB, UD, and their associated components. U6 is a four-quadrant analog multiplier connected as a variable gain, wide-band, linear amplifier. The modulation reference (I) input is multiplied by a factor determined by the level of the carrier ref (I) and B+ ref (I4) inputs to determine the gain and, in turn, the I output. When there is no unbalanced audio input at J-5, UD's output (TP6), which is the modulation reference, will be a nominal.4 V. When a pure audio sine wave is present at a level that will produce 00% modulation, the output of UD will be a sine wave varying from 0 V to.8 V. The resulting current flow through R is U6's I input. Page -8 Issue

77 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions The carrier ref input at J- is a dc voltage directly proportional to the expected RF carrier level squared. When the transmitter is operating at its rated carrier level, the expected carrier ref input at the output of buffer UA (TP5) is a nominal 4.7 V. The resulting current flow through R is U6's I input. The B+ ref () input at J- and the voltage at the output of buffer UD (TP) is a dc voltage directly proportional to the B+ voltage being applied to the transmitter's RF power stage. When the B+ voltage is 50 V (for high power operation), the voltage at TP is a nominal 6. V. The resulting current flow through R0 is U6's I4 input. The gain of U6 and, in turn, the current flowing from its I output, is determined by the following formula: I = I x I/I4 When the carrier ref input (I) is 4.7 V (transmitter's rated output power) and the B+ ref () input (I4) is 6. V (B+ voltage of 50 V), the gain of U6 is 0.76 for the modulating reference applied to I. U6's I output current is 0.76 times its I input current. UB is connected as a less than unity amplifier and its gain is summed with U6's gain. The end result is the total voltage gain of the circuit, relative to the voltage at the output of UD (.4 V when no audio is present), is a nominal 0.67 when GAIN TRIM potentiometer R is set to the centre of its range. When there is no modulation present, the carrier ref + audio output of UB (TP8) is 0.94 V (.4 V x 0.67). The gain of U6 will change in direct proportion to changes in the carrier ref voltage. If the carrier ref voltage is set to 0 V, or it is clamped to ground because Q is on, U6's gain is zero. In turn, the modulating reference's multiplication factor is minimum (zero). The transmitter's RF output is set to 0 W. The gain of U6 will change in inverse proportion to changes in the B+ ref () input. This feature eliminates the need for sophisticated filtering of the transmitter's B+ power supply and maintains the transmitter's RF output at the original level for B+ voltage variations of ±0%. GAIN TRIM potentiometer R provides a nominal 0% adjustment in the carrier ref + audio output of UB. It is adjusted in dual exciter applications to compensate for tolerance differences in the PDM generators of exciter A and exciter B. When it is set properly, the transmitter's RF output level is the same when either exciter is selected, provided the same desired ouput level is being applied. PDM divider The PDM divider circuit divides the f PDM input frequency (J-7) by two. The resulting f PDM output (J-0) is a 0 V to 5 V square wave at half the f PDM frequency. See N divider on page -7. Issue Page -9

78 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Linear integrator The linear integrator circuit converts the f PDM square wave on its input to a triangular waveform at its output. The triangular waveform has negative and positive voltage excursions of equal amplitude and duration. The long R/C time constant formed by C7/R ensures a linear rise and fall time. Integrator peak detector The integrator peak detector circuit detects the positive going excursions of the linear integrator's triangular waveform. A portion of the resulting positive dc voltage (nominally.8 V) at U8A's output, is applied to the inverting input of differential amplifier UA. The carrier ref + audio output of UA is offset by this voltage which is proportional to the triangular waveform voltage peaks. This offset effectively sets the carrier ref + audio's zero power reference to the triangular waveform's peak voltage. This technique ensures no RF output is produced when the carrier ref input (J-) is 0 V. It also ensures the RF output is reduced to near 0 W at the 00% modulation envelope valleys when operating at the transmitter's rated carrier level. Interphase pdm generator The interphase PDM generator consists of two variable pulse duration generators (PDM and PDM). Both produce identical 0 V to +5 V rectangular waveforms at the PDM repetition rate, but they are 80 0 out of phase with each other. The waveform on/off ratio (duty cycle) is directly proportional to the carrier level and amplitude of the modulating audio. PDM generator The PDM generator consists of U0B, Q4, Q5, and their associated components. The compensated carrier ref + audio input from the integrator peak detector circuit is applied to differential amplifier U0B's non-inverting input, where it is compared to the triangular waveform from the linear integrator circuit. When the compensated carrier ref + audio is more positive than the triangular waveform, U0B's output is an open collector. +5 V is applied through R60 and R6 to the balanced drive formed by Q4/Q5. Q4 turns on and applies +5 V to K- as the PDM output (Q5 is off). For the remainder of the triangular waveform's period, the compensated carrier ref + audio is less positive than the triangular waveform. U0B's output is a current-sink-to -5 V and Q4 turns off. Q5 turns on and clamps the PDM output to ground. The minimum 'on time' (zero RF power) occurs at the negative peaks of the triangular waveform. See Figure. on page - for a timing diagram. Page -0 Issue

79 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Figure.: Timing Diagram for PDM Differential Amplifier Carrier Reference Level Ramp PDM Inverted Carrier Reference Level Ramp PDM PDM generator The PDM generator consists of UC, UB, Q6, Q7, and their associated components. It operates similar to the PDM generator except UC inverts the compensated carrier ref + audio input and applies it to differential comparator UB's inverting input. The result is a PDM 'on period' when the compensated carrier ref + audio is less positive than the triangular waveform and produces a minimum 'on time' at the positive peaks of the triangular waveform. The on/off ratio of the PDM and PDM outputs are the same, but the zero power reference change for the PDM output is offset, relative to the PDM output, by one half of the PDM repetition rate. PDM fault detector The PDM fault detector circuit contains two identical voltage controlled switches (one for each PDM output) that control the 'set/'reset' status of the shutback latch circuit and, in turn, controls the on/ off status of relay K. For explanation purposes, only the PDM fault detector is described. The PDM fault detector circuit consists of UA and its associated components. R67/C58 form an integrator with a long time constant, relative to the PDM frequency. C58's charge voltage is applied to UA's inverting input and compared to the 7. V reference voltage applied to its non-inverting input from voltage divider R70/R7/ R7. UA's output is an open collector and has no influence when C58's charge voltage is less positive than the reference voltage. UA's output will switch to a current-sink-to-ground when C58's charge voltage goes more positive than the reference voltage. Issue Page -

80 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions During normal operation, C58 will charge through R67 towards 5 V when the PDM output is 5 V (during its 'on time') and CR is reversed biased. It will instantly discharge to ground potential, through CR, when the PDM output switches to 0 V (during its 'off time'). The repetition rate of the PDM on/off periods ensures the charge on C58 will not exceed 7. V, provided each PDM cycle contains an 'off time'. If a PDM failure occurs that produces a continuous 'on time', C58 will charge more positively than 7. V. UA's output will switch to a current-sink-to-ground and toggle the shutback latch circuit to its 'set' state. Shutback latch The shutback latch circuit inhibits the 'on time' of the PDM outputs and, in turn, the RF output of the transmitter whenever a transmitter originated Inhibit PDM (J-6) command is applied. This circuit provides additional protection to the transmitter's RF power stages when faults are detected or actions are initiated that may cause RF stress current thresholds to be exceeded. Its function is to deenergize K and disconnect the PDM /PDM outputs from the transmitter circuits when the PDM fault detector output is a current-sink-to-ground (logic low). It also inhibits the PDM generators when relay K is de-energized or when a logic true inhibit PDM command is applied to J-6. U9A/U9B form a bistable flip/flop. The flip-flop's output, at U9-, will be 5 V (logic high) when in its 'reset' state, and a current-sink-to-ground (logic low) when in its 'set' state. Normally the inhibit PDM input and the output of the PDM fault detector circuit, which are the flipflop's controlling inputs, are open collector. 5 V (logic high) are applied to U9- and U9 5 through their pull-up resistors and the flip-flop is latched in its 'reset' state. Relay K is held energized and the PDM outputs are applied to the transmitter circuits. If a PDM fault is sensed, the PDM fault detector circuit applies a current-sink-to-ground (logic low) to U9-5 and causes the flip-flop to switch to and latch in its 'set' state. Relay K de-energizes and disconnects both PDM outputs from the transmitter circuits. The PDM latch output (J-) is activated (5 V). This condition is maintained until the flip-flop is reset by the removal of the logic low from U9-5 (no PDM fault) and the application of logic low to U9- (a logic true current-sink-toground reset PDM command is applied to J-). PDM inhibit The PDM inhibit circuit consists of U9D, Q, Q, and their associated circuits. Its function is to instantly clamp the output of both PDM generators to ground (zero carrier level) whenever a logic true (current-sink-to-ground) inhibit PDM input is applied to J-6, or when the PDM fault detector circuit senses a PDM fault and the shutback latch circuit's flip-flop is latched in its 'set' state. When neither of these conditions are true, the PDM inhibit circuit has no influence. Page - Issue

81 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Dump circuit The dump circuit, consisting of DUMP potentiometer, UC, UA and UB, is not used in this transmitter. Remote interface PWB (NAPI8/0A) See electrical schematics Figures SD-5 through SD-8. The remote interface PWB performs the following functions: Buffers all external remote control inputs and remote status/alarm outputs. Provides buffered, analog sample voltages proportional to the B+ supply voltage, total dc current, audio, forward power, and reflected power for external monitoring. Conditions the audio (analog or DAB) input's gain and provides filtering and modulation protection. Provides monitoring samples of the transmitter's RF output (both analog and DAB). The magnitude of the analog sample is automatically adjusted to ensure a relatively constant voltage, nominally V rms, regardless of RF output level. Provides the connection for the system's external interlock circuit between TB- and TB-. Remote inputs RFI filtering is provided on all control input lines to ensure transmitter operation is not interrupted due to RF pick up on control lines. Opto-couplers are provided to buffer/isolate the external circuits and prevent any unwanted transients from affecting transmitter operation. The position of shorting SINGLE/DIFF jumper E9 allows the control inputs to be configured to operate from a single-ended or differential input. Refer to Control and monitoring section of the XR6/XR Installation Manual for a detailed description on single-ended versus differential inputs. Issue Page -

82 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Remote outputs Remote alarm/status outputs are provided on pins of connectors J and J. A darlington transistor for each alarm/status output provides a negative logic (current-sink-to-ground) output when a logic 'true' (alarm condition or active status) exists. The switching circuit provides an open collector during logic 'false' conditions (non-alarm or non-active status condition) and has no influence on the external monitoring circuit. Each monitoring circuit must present impedance between the switching device and a positive dc voltage source that results in a current flow of not more than 50 ma. +4 V is available for use by the remote monitoring circuits on TB-7. Audio input Analog audio input is applied to the AUDIO terminals [+ (TB-), - (TB-) and SHIELD (TB-)]. The Magnitude component of the IBOC audio input, if used, is applied to RJ45 connector J0 [MAG (IN)] of the remote interface PWB. The Phase component is applied to J4 (RF PHASE) of the RF drive buffer PWB. The optional DCC inputs are applied to pins of D-sub connector J. When the DCC option is used, the analog audio is routed to the DCC PWB via relays K. The audio signal is then applied to the balance/unbalance circuit. The state of relay KC determines the amplitude modulating source - analog or IBOC program. Balance/unbalance circuits The balance/unbalance circuits, which converts the balanced audio input or IBOC magnitude input to an unbalanced signal, consists of U7A or U8A and its associated components. The output of differential amplifier U7A or U8A is an unbalanced audio that is a positive voltage for positive half cycles and a negative voltage for negative half cycles. Any unwanted noise transients that are induced on the audio input will be in-phase and of equal amplitude. Since the transients are in-phase and of equal amplitude, they have no influence on U7A's or U8A's output and they will not appear at U7A's or U8A's output. Zero crossing detector The zero crossing detector, for analog audio only, consists of UC, Q7, CR6, and associated components. This circuit is the +5 V charge voltage source for C7 during the negative audio halfcycles. During positive audio half-cycles it is effectively open circuit and has no influence on the charge state of C7. A small dc bias (0. V) is present on UC's non-inverting input. Page -4 Issue

83 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Modulation level detector The modulation level detector circuit monitors the on/off times of the Forward Power Sample input (J-) for excessive on times. It automatically inhibits a portion of any modulating audio's positive going half-cycle that would cause excessive 'on times' and results in the stress current threshold of the transmitter's RF power amplifier stages being exceeded. The circuit consists of comparators UA, UB, UC, UD, UA, UB and associated components. It provides a discharge path to -5 V for C7 when the 'on time' of the Forward Power Sample input will result in modulation peaks that exceed safe operating levels. The Forward Power Sample input, applied to the inverting inputs of each comparator, is a varying positive dc voltage directly proportional to the RF output's modulation envelope. The audio component is synchronized with the audio output of UC and is the most positive at the peak of the modulating audio's positive half-cycle. Each comparator has a reference voltage applied to its non-inverting input that represents the RF stress current threshold for a specific carrier level/audio amplitude/audio frequency combination (see Table.). MOD PROT THRESHOLD potentiometer R65 is adjusted to precisely set the threshold voltages, when the PWB is installed in a transmitter. When the voltage representing the modulation envelope exceeds the RF stress current threshold of a comparator, that comparator connects its output resistor to -5 V and provides a discharge path for C7. The time for C7 to discharge to a negative voltage is dictated by the number of resistors connected to -5 V (modulation amplitude) and the period of time they are connected (audio frequency). C7's discharge time (dictated by the R/C time constant) is progressively faster as the modulation depth increases (more comparator thresholds are exceeded) and it has a longer time to discharge as the audio frequency decreases. See Table. for the duration of a positive half-cycle at the lowest unaffected audio frequency for specific modulation depths. Table.: Peak Modulation Limit Threshold Mod Depth Peak % Lowest Unaffected Freq (Hz) Duration (ms) Issue Page -5

84 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Audio chopper The audio chopper circuit consists of UD, Q, and their associated components. It inhibits some portion of positive audio half-cycles that cause modulation peaks/durations that exceed the RF stress current threshold of the transmitter's RF power amplifiers. It accomplishes this by clamping the modulating audio to ground whenever the charge voltage on C7 switches from a positive value to a negative value and retains this state until C7's charge voltage returns to a positive value at the end of the positive audio half-cycle. When C7 has a positive voltage charge, UD's non-inverting input is more positive than its inverting input. UD's output is an open collector. Q is reverse biased and has no influence on the modulating audio. The Mod Protection output (J-) is open collector (logic negative state). When the modulation level detector circuit provides C7 a discharge path to -5 V (because one or more RF stress current thresholds have been exceeded) for a long enough period of time to achieve a negative voltage charge, UD's non-inverting input will go less positive than its inverting input. UD's output is a current-sink-to -5V and causes Q to be forward biased (turned on). The modulating audio is clamped to ground by Q until the start of the next negative audio half-cycle (for the balance of the current positive audio half-cycle), when the zero crossing detector circuit provides a low impedance source to +5 V and charges C7 to a positive value. The Mod Protection output is a current-sink-to-ground (logic true state) for each offending positive audio half-cycle. The system diagram's Exciter lamp will flash on and off when this circuit is active. Audio gain U9A is connected as a unity gain, buffer amplifier. AUDIO GAIN potentiometer R60 is adjusted for the desired modulation depth when the interphase PDM driver PWB is installed in its host transmitter. It has sufficient range to set the modulation depth at 00% when the audio input is between 0 dbm and + dbm. Audio filter The audio filter circuit is a low pass filter with a -.0 db, high frequency roll-off at one of four userselected frequencies. The AUDIO FILTER switch S has settings to select one of four roll-off frequencies (6.0 khz,.5 khz, 0.5 khz or 7.5 khz). The high frequency roll-off selection is normally dictated by complex factors, such as an antenna with sideband limitations, square wave overshoot, or the equipment that pre-processes the audio. The AUDIO FILTER switch and audio filter are bypassed when IBOC program input is used. Magnitude gain MAG GAIN potentiometer R7 is adjusted for the correct magnitude signal when connected to an NE IBOC exciter for IBOC operation. Page -6 Issue

85 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions RF monitor and gain setting A sample of the transmitter s RF output is applied from the RF output filter to the RF Sample input (J7). The front panel GUI, in conjunction with microcontroller U4 and variable gain amplifier U, provide a means to change the level at the RF MONITOR output (J8). This output (BNC connector) provides a true RF sample of the RF output voltage waveform and is intended for use by a modulation monitor. The BYPASS/GAIN switch (S) provides a means to multiply the RF monitor sample by five. When the BYPASS/GAIN switch is set to BYPASS, the RF monitor sample voltage is a nominal V rms. When the BYPASS/GAIN switch is set to GAIN, the RF monitor sample voltage increases to a nominal 5 V rms. Issue Page -7

86 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions RF drive power supply PWB (6 V) (NAPS0B) See electrical schematic Figure SD-. The RF drive power supply PWB is a boost type switching power supply which provides a regulated dc supply voltage for the transmitter's RF drive amplifiers. A nominal +48V supply is applied to the drain of switching FET Q through inductor L. The gate of FET Q is driven with pulses from pulse width modulation (PWM) switching power supply control U. This device is a fixed-frequency PWM control circuit, incorporating the functions required for the control of a switching power supply. Internal to the device is a sawtooth oscillator which is set to a nominal frequency of 00 khz by external components R6 and C6. The output, PWM control pulses to the gate of FET Q, is generated by the comparison of this sawtooth waveform with a feedback voltage sample from the junction of U-Cathode and the bias voltage created by VOLTAGE CONTROL potentiometer R. The resultant variable pulse width output (U-8) is applied to the gate of FET Q. Q turns on and off, ringing inductor L with the appropriate pulses to maintain the desired set dc output voltage. Diode pair U rectifies the signal and inductor L and capacitor C9 provide filtering for the RF Drive B+ output voltage. A sample of the dc output voltage level is applied through zener diode CR to the base of transistor Q which provides an alarm signal should the RF drive power supply fail. The RF Drive B+ Fail alarm output is normally at ground potential and switches to an open circuit condition should a failure occur in the RF drive power supply. Page -8 Issue

87 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions RF power module (NAP4A) See electrical schematics Figures SD-9 and SD-0. The RF power module is effectively two wideband RF amplifiers for the AM broadcast frequency band (50-70 khz). The RF power module consists of an RF drive control PWB, an RF drive tuning assembly, a modulator input/output PWB and duplicated assemblies for the two wideband amplifiers. Each wideband amplifier contains two power blocks (A/B or C/D) that share an RF output transformer. A power block consists of a modulator assembly, a modulator filter, a PA input/output PWB and two RF amplifier sections. RF drive control pwb See electrical schematics Figures SD- through SD-. The RF drive control PWB (A) performs a number of functions. They include: Buffering, amplifying and tuning the RF drive Monitoring RF drive level and tuned status Verifying PA volts is representative of the carrier level and modulation information contained in the PDM signals Splitting and distributing the PDM signals Monitoring the temperature of the RF amplifier's heat sinks Generating alarm signals for visual display of fault conditions when a failure occurs Inhibiting RF output when a failure occurs that would exceed the stress threshold of the MOSFETs in the RF amplifiers RF drive amplifier The RF drive amplifier is a class 'D' switching mode amplifier. It buffers and amplifies the low level RF drive applied between J4-5 and J4-. The resultant (0-6 V, approximately) square wave, at the carrier frequency (f c ), is applied to C8 and C9, which form the first pole of the RF drive tuning filter. The secondary of T provides an RF drive sample at TP5 that represents its current waveform. Issue Page -9

88 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions RF drive b+ current limiter The RF drive B+ current limiter is effectively a voltage controlled variable resistor in the RF drive amplifier's B+ voltage path. The magnitude of the control voltage applied to the base of the reference power transistor is determined by circuitry which monitors the RF drive signal's voltage and current. No Limiting: Under normal conditions, the reference power transistor will be turned on and operating in its saturation region due to the voltage across R. The reference transistor s emitter-collector voltage will be minimal (0. V) and unrestricted current from the RF drive volts supply will flow to the RF drive amplifier (see RF drive amplifier on page -9). If the RF load on the RF drive amplifier is not tuned properly, current will be limited by one of two out of tolerance parameters - excessive RF drive current or RF drive voltage. High RF Drive Current Limiting: Resistors R0, R9 and transistor Q, in conjunction with the reference power transistor, form a circuit which limits the current drawn by the RF drive amplifier to.0 A. When the RF drive current flowing through the parallel combination of R0/R9 exceeds.0 A, Q's base-emitter voltage will exceed 0.64 V. Q will turn on and conduct current, resulting in an increased voltage across resistor R. This voltage, proportional to the level of current flowing through R0/R9, is applied to the reference transistor's base. The reference transistor drops out of saturation and enters its linear region. The voltage across its emitter-collector junction will increase, limiting the current drawn by the RF drive amplifier. High RF Drive Voltage Limiting: Diode CR5, resistors R0, R and capacitor C9, in conjunction with the reference power transistor, form a circuit which acts to limit the tuned RF drive peak voltage to approximately 00 V. When the tuned RF drive voltage exceeds approximately 6 V, CR5 begins to conduct during the tuned RF drive signal's positive half-cycles. The current conducted through CR5 is low-pass filtered by R0 and C9, resulting in an increased voltage drop across resistor R. When the peak tuned RF drive voltage reaches 00 V, the voltage across R is sufficient to cause the reference transistor to enter its linear region. The voltage across its emitter-collector junction will increase and cause the current drawn by the RF drive amplifier to decrease, limiting the tuned RF drive voltage to approximately 00 V.

89 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Latching low rf drive detector Comparator UD and the peak detector formed by CR8/C7/R6 form the latching low RF drive detector circuit. The RF drive level applied to CR8, which is a sample of the tuned RF drive voltage waveform (from the secondary of T), is peak detected and applied to UD's inverting input. It is compared to a 4. V reference, from voltage divider R5/R7, which is applied to UD's non-inverting input as the low RF drive threshold. When the RF drive level is satisfactory, the peak detected dc voltage applied to UD's inverting input will be more positive than 4. V. UD's output will be a current-sink-to-ground, causing UE's output to be open collector. The latching low RF drive detector circuit will have no influence. When the RF drive level is not satisfactory, the peak detected dc voltage applied to UD's inverting input will be less positive than 4. V. UD's output will switch to an open collector. 4 V will be applied, through pull-up resistors R6/R5, to UE's input and through CR9 to UD's non-inverting input. UD will latch in its open collector output state and remain there until +4 V is removed from pullup resistor R5, by the application of a ground potential reset command to the junction of R6/R5, by the reset pulse generator circuit (see Reset pulse generator on page -4). UE's output will switch to a current-sink-to-ground. This current sink-to-ground will be applied to: RF DRIVE FAIL LED DS8, through R0. The RF DRIVE alarm lamp on the module's front panel will turn on. through CR, to the inverting input of UA. The output of UG, also a current-sink-toground, is applied to CR7, CR9, CR4 and CR4, as a logic true Pwr Mod Fail signal which clamps the PDM (A)/(B)/(C) and (D) outputs to ground. All four low PA volts detectors will be latched in their no-fault states (see Low PA volts detector on page -) and the modulators for all four power blocks will effectively be turned off. When a logic true (+5 V) Inh RF Dr Fault command is applied to J4-, indicating the automatic RF drive tuning feature has been enabled (normally after a repair or a frequency change), +5 V is applied to UD's inverting input through CR7. The latching low RF drive detector will be latched in the acceptable level state, as described previously, for as long as the +5 V Inh RF Dr Fault command is applied to J4-. Issue Page -

90 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions High temp detector Comparator UB in conjunction with two negative temperature coefficient thermistors mounted on the module's heat sinks, form the high temp detector circuit. The thermistors are connected in parallel and, with R, form a voltage divider to +5 V. The voltage output of the voltage divider is applied to the inverting input of UB. It is compared to a 4.8 V reference, from voltage divider R0/ R, which is applied to UB's non-inverting input as the high temperature fault threshold. When the temperature sensed by both thermistors is less than a nominal 85 C, the parallel impedance of the thermistors will be more than 6000 ohms and the dc voltage applied to UB's inverting input will be more positive than +4.8 V. UB's output will be a current-sink-to-ground, causing UC's output to be an open collector. The high temp detector circuit will have no influence. When the temperature sensed by one or both thermistors is greater than a nominal 85 C, the parallel impedance of the thermistors will be less than 6000 ohms. The dc voltage applied to UB's inverting input will be less positive than +4.8 V and cause UB's output to be an open collector. +4 V will be applied through pull-up resistors R6/R7 to UC's input and cause UC's output to switch to a current-sink-to-ground. This current-sink-to-ground will be applied to: UB's inverting input, through CR, and cause it to latch in the high temp fault state. This state will be maintained until +4 V is removed from R7, by the application of a ground potential reset command to the junction of R6/R7, by the reset pulse generator (see Reset pulse generator on page -4). HIGH TEMP LED DS7, through R0. The TEMP/INHIBIT alarm lamp on the module's front panel will turn on. through CR4, to the inverting input of UA. The output of UG, also a current-sink-toground, is applied to CR7, CR9, CR4 and CR4, as a logic true Pwr Mod Fail signal which clamps the PDM (A)/(B)/(C) and (D) outputs to ground. All four low PA volts detectors will be latched in their no-fault states (see Low PA volts detector ) and the modulators for all four power blocks will effectively be turned off. The high temp detector is also used to inhibit operation of the RF power module when it is to be removed from an on-air transmitter. The module's Inhibit switch applies a ground potential as the RF inhibit command to the RF Inhibit input (J4-) when it is pressed and released. This ground potential simulates an excessive temperature and causes the high temp detector to latch in its fault state as described previously. Low PA volts detector There are four identical low PA volts detectors, one for each power block. Since they are all identical, only the circuit for power block A is described. Page - Issue

91 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Comparator U6A, inverter U7A and their associated components form the low PA volts detector 'A' circuit. The PDM signal applied to J- is applied through R5 to an average detector formed by R58/C48. The average detector's output, which will be a positive dc voltage, is applied to U6A's non-inverting input. Since the PDM input is 0-5 V, varying pulse width, the magnitude of this voltage is dependent on the on/off ratio of the pulses. The carrier level component of the PDM information, will produce a mean voltage level between.5 V (minimum) and 6.0 V (maximum). Modulation components are filtered out by capacitors C46 and C48. The PA Volts (A) input applied to J-5 is a dc voltage which is a derivative of the same PDM information as the PDM signal, but it is referenced to the B+ (0 V) voltage. The carrier level component of the PDM information will produce a mean voltage level of V (minimum) to 0 V (maximum). A portion of the PA Volts (A) input is applied to U6A's inverting input by dual voltage divider R5/R56/R57. The voltage divider to +5 V formed by R56/R57, ensures a minimum of.0 V is applied to U6A's inverting input during initial turn on while the B+ power supplies are ramping up to full power. During normal operation, the PA volts sample applied to U6A's inverting input is more positive than the reference voltage applied to its non-inverting input. U6A's output is a current-sink-to-ground and cause U7A's output to be an open collector. 5 V is applied to J-, through pull-up resistor R68, BLOCK A LED DS and diode CR5, as the current source for the thyristor in the PA input/output PWB's RF amplifier failure circuit. The logic level of the RF Amp Fail (A) signal is dependent on the status of the RF amplifier failure detector circuit (see RF amplifier failure detector on page -7). 5 V is applied to the pwr module fail detector circuit, from pull-up resistor R68, as a logic false block fail (A) output to the power module failure detector circuit; provided a ground potential is not being applied to J- as a logic true RF Amp Fail (A) input. When a modulator malfunction occurs that results in the PA volts being less than the expected level, the PA volts sample applied to U6A's inverting input will be less positive than the reference voltage applied to its non-inverting input. U6A's output will switch to an open collector. 4 V will be applied through pull-up resistor R64/CR to U6A's non-inverting input and through R65 to U7A's input. U6A will latch in its fault (open collector) state and remain there until it is reset by the application of a ground potential reset command through CR6. Issue Page -

92 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions U7A's output will switch to a current-sink-to-ground. A ground potential will be applied to the junction of DS/CR5 through CR4. The 5 V current source will be removed from J-. The PA input/output PWB's RF amplifier fault detector circuit will be reset if it was activated. Its fault detection capability will be inhibited as long as the junction of DS/CR5 is a ground potential (see RF amplifier failure detector on page -7). Modulator short circuit detector There are four identical modulator short circuit detectors, one for each power block. Since they are all identical, only the circuit for power block A is described. Comparator U0A and its associated components form the modulator short circuit detector. A +5 V reference voltage is applied to U0A's non-inverting input. The PA Volts (A) input (J-5) is a dc voltage that is representative of the PDM signal. A portion of the PA Volts (A) input is applied to U0A's inverting input by dual voltage divider R5/R56/R57. During normal operation, the PA voltage sample applied to U0A's inverting input will be less positive than the reference voltage applied to its non-inverting input. U0A's output will be open collector. When a modulator malfunction occurs, which results in the PA voltage being the same as the B+ voltage (i.e., a shorted FET in the modulator), the PA voltage sample applied to U0A's inverting input will be more positive than the reference voltage applied to its non-inverting input. U0A's output will switch to a current-sink-to-ground, causing the MOD SHORT LED (DS9) to turn on. Reset pulse generator Transistor Q and inverter UA are connected as a one shot pulse generator. When a momentary ground potential is applied to J4-0 as a logic true Reset PM command, Q will turn on. 5 V will be applied to the input of UA and cause its output to switch to a current-sink-to-ground while Q is on. This current-sink-to-ground will: Remove the 4 V pull-up voltage from the junction of R6/R7 and effectively clamp UC's input to ground potential. UC's output will be clamped to its open collector state for the reset pulse period. If UB was latched in its high temp fault state, UC's open collector state will unlatch UB and reset the high temp detector. Remove the 4 V pull-up voltage from the junction of R6/R5 and effectively clamp UD's output to ground potential for the reset pulse period. If UD was latched in its low RF drive fault state, the removal of the 4 V pull-up voltage will unlatch it. The latching low RF drive detector will be reset. Page -4 Issue

93 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Be applied to the cathodes of CR6, CR8, CR40 and CR4 as a logic true reset command. The PDM input to all four low PA volts detectors will effectively be clamped to ground for the duration of the reset pulse. Any low PA volts detector which was latched in its fault state will be reset. Alarm indicators The RF drive control PWB contains lamps (LEDs) which are visible through the RF power module's front panel. The dc voltage for all alarm lamps is applied through transistor Q7's base-emitter resistor R98. When an alarm lamp is turned on, the resultant current flow through R98 will forward bias Q7 and turn it on. A nominal V will be applied to J- as a logic true PM Fault output. Manual rf drive tuning See electrical schematic Figure SD-9. The manual RF drive tuning assembly contains two variable inductors (L and L) which are connected to form two poles of the RF drive's tuned circuit. Their inductance is determined by the positioning of their moveable cores. When the RF drive screw is turned clockwise, the inductance of the inductors decreases. See RF drive tuning check on page -6 for information on manually tuning an RF power module. RF power blocks See electrical schematics Figures SD-9 and SD-0. There are four identical RF power blocks. Each utilizes one quarter of the modulator input/output PWB (A4), a modulator assembly, a modulator filter, PA input/output PWB and two RF amplifiers. The RF power blocks (A/B and C/D) are connected in parallel. See Figures SD-9 and SD-0 to determine which assemblies are associated with a specific RF power block. Modulator stage See electrical schematics Figures SD-9 and SD-0. The modulator stage contains the modulator input/output PWB, four modulators, and four modulator filters. The function of each modulator is to act as a voltage regulator between the B+ voltage and the power MOSFETs in its associated RF amplifiers. The voltage control is provided by the carrier level/modulation envelope information on the PDM inputs. Issue Page -5

94 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Modulator input/output pwb The modulator input/output PWB interfaces the B+ VDC, PDM, and gate bias drive inputs and the PDM (B+) outputs of the four modulator assemblies. The B+ voltage for each modulator is separately fused at 0 A. The PDM signal for each modulator and the 5 V input are separately fused at 0.5 A. Transient suppressors CR through CR5 limit transients from feeding back to the control circuitry during failures. Modulator assembly See electrical schematics Figures SD-0 and SD-4. Each modulator assembly is effectively a logic level converter that converts the low level (0-5 V) logic of the PDM input to a high level (0-B+) logic PDM (B+) output. V Power Supply: The 4 V ac Gate Bias Drive input, at the PDM frequency, is full-wave rectified by the bridge rectifier formed by CR through CR4. The resultant dc voltage is filtered by capacitor C4 and limited to V by zener diode CR5. The power supply's less positive output is referenced to the source terminal of power MOSFETs Q through Q6 through R4, therefore the positive output will always be V more positive than the voltage on the FET source terminals. The V output is applied to the VB (+) and VS (-) inputs of FET driver U as the switched gate drive for the power MOSFETs. FET Driver: FET driver U is an integrated circuit that is configured to produce outputs as follows: when the HIN input is high (5 V), the HO output is the dc voltage applied to VB input; when the HIN input is low (0 V), the HO output is the reference voltage applied to VS input. The HO output, which contains the PDM data, is applied to the gates of power MOSFETs Q through Q6 as their on/off control. B+ Switching MOSFETs: Power MOSFETs Q through Q6 are connected to switch the B+VDC on and off at the on/off ratio of the PDM data on U's HO output which is applied to their gates. The resultant PDM (B+) output contains the PDM data applied to J- at a high level (0 - B+) logic level. U is connected as a free wheel diode to prevent the PDM (B+) output from going negative as the current collapses when Q through Q6 are turned off. Page -6 Issue

95 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Modulator filter See electrical schematic Figure SD-0. An inductor, L/C components on the modulator filter and the input capacitance of two RF amplifiers form a low pass filter for the modulator's PDM (B+) output. The filter is connected as a multi-pole, tuned filter that shunts the PDM frequency component of the PDM (B+) input to ground. The filter output (PA Volts) will be a positive voltage that is the sum of a dc component (RF carrier level) and an ac component (modulating audio). The ratio of the PA Volts amplitude in relation to the B+ voltage is the same as the on/off ratio of the PDM (B+) input. When the on/off ratio is constant (carrier level only present), the PA Volts output will be a constant dc voltage. When the PDM (B+) on/off ratio is varying (carrier level plus modulation present), the PA Volts output will be a dc voltage that varies from the carrier level voltage at the modulating audio frequency. The amplitude of the variations is determined by the amount the PDM (B+) on/off ratio varies. B+ decoupling assembly See electrical schematic Figure SD-0. The B+ decoupling assembly provides decoupling and transient suppression for the B+ inputs on the modulator input/output PWB. PA input/output pwb See electrical schematic Figure SD-9. There are four identical PA input/output PWBs, one for each of RF power block. They: distribute PA volts to both RF amplifiers associated with the power block. split and apply the RF drive to both RF amplifiers associated with the power block. monitor RF drive current to both RF amplifiers and produce an RF amp fail output if they are not balanced (indicates a failure in one or both of the RF amplifiers). apply the RF output of both RF amplifiers to individual primary windings of an RF combining transformer. RF amplifier failure detector The RF drive is split and applied to the anti-phase wound primary windings of transformer T. The voltage transformed to T's secondary is directly proportional to the difference in the RF drive current flowing through its primary windings. Any voltage transformed to the secondary winding is half-wave rectified and applied to the gate of thyristor Q. Issue Page -7

96 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Normally, the RF drive currents will be balanced, there will be minimal voltage across T's secondary and the voltage applied to Q's gate will not be sufficient to forward bias it. Q will be turned off and the RF Amp Fail signal will be logic false since 4 V is being applied from a pull-up resistor in the RF drive control PWB's crowbar switch circuit. When the RF drive currents are significantly unbalanced, the voltage across T's secondary will be sufficient to forward bias Q and Q will turn on. A current-sink-to-ground applied to its cathode from the RF drive control PWB will be applied to the RF drive control PWB's crowbar switch circuit as a logic true RF Amp Fail signal. This status will be maintained until the RF power module is removed from the transmitter or the transmitter's ac power source is turned off. RF amplifiers See electrical schematics Figures SD-9 and SD-5. There are eight identical RF amplifiers in an RF power module. Refer to Figure SD-9 to determine which are associated with a specific RF power block and then to figure SD-5 for the electrical schematic of an RF amplifier. Each RF amplifier uses four parallel-connected pairs of MOSFETs (Q through Q8) to produce unfiltered, modulated RF output. The power transistors are connected as two parallel, high efficiency, push-pull, class D RF power amplifiers which switch the PA Volts at the RF drive frequency (Figure. on page -9). RF drive splitter transformers UT and UT split the RF drive signal and apply it to transistors Q through Q8 with the required phase relationship. Diodes CR through CR4 prevent the output of the RF amplifier from going negative. Page -8 Issue

97 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions Figure.: Simplified Principles of Class D Operation Simple Class 'D' Operation If the switch is opened and closed with a 50% duty cycle, a square wave at the switching frequency results at the filter input. If the filter passes the switching frequency, but attenuate its harmonics, a sine wave is applied to the load. Push Pull Class 'D' Operation If S and S are opened and closed with a 50% duty cycle, a square wave of current, at the switching frequency, is passed through the primary of the transformer and transformed to its secondary. If the filter passes the switching frequency, but attenuate its harmonics, a sine wave is applied to the load. Power MOSFET Class 'D' Operation Power MOSFETs can be used to replace the switches as depicted in the simple class 'D' operation and push-pull class 'D' operation examples. Note that the switch contacts are replaced by the phaseoriented secondaries of an RF drive transformer. Q corresponds to S-A, Q to S-B, Q to S-B and Q4 to S-A, as depicted in the push-pull class 'D' operation example. Q and Q4 turn on/ off together and Q and Q turn on/off together. Issue Page -9

98 XR6/XR Troubleshooting Manual Detailed Circuit Descriptions RF drive buffer PWB (NAPE77A/0) See electrical schematic Figure SD-0. The 0-5 V RF carrier frequency signals generated by the RF synthesizer PWBs are applied to the RF Drive A (J) and B (J) inputs. The active RF Drive signal, as selected by relay K, is applied to MOSFET drivers UA through U5A. The buffer amplified RF Drive and (B)signals are applied to the RF power modules. An identical test signal is provided on the RF DRIVE (TEST) output (J5). A sample of the active RF Drive input is peak detected by diode CR, resistor R5 and capacitor C and applied to the inverting input of operational amplifier UA. During normal operation, this dc voltage is greater than the threshold voltage (4. V) applied to UA s non-inverting input. UA s output is 0 V, which turns off transistor Q. The RF Drive Fail output (J-8) is open collector (nonalarm state). If the RF drive signal becomes too low or disappears, the voltage applied to UA s inverting inputs is below the 4. V on the non-inverting input. UA s output switches to 5 V, which turns on transistor Q. The RF Drive Fail output (J-8) switches to a current-sink-to-ground (alarm state). This alarm signal is applied to the control/display PWB via the distribution PWB and exciter interface PWB. A SENSITIVITY jumper (E) is provided to change the level required to cause an RF Drive Fail alarm. If the transmitter is configured for IBOC, this jumper should be set to LOW (shorting pins and ). The IBOC phase input, if used, is applied to the RF Phase In inputs [J4-5 (+) and J4-4 (-)]. The signal is applied through RF transformer T and inverters UA and U D, where it is connected to both RF Drive A and B signal paths. Shorting jumpers E and E must be set in the EXT position (shorting pins and ) for IBOC use. Page -0 Issue

195 XR6/XR Troubleshooting Manual Wiring/connector lists Section 4: Wiring/connector lists This section contains the wiring information for the hard-wired assemblies of the transmitter, and applicable connector mating information. Wiring lists provided Wiring lists are provided in tabular format. Table 4. on page 4- lists the tables containing wiring information. These tables provide non-printed wiring pattern, point-to-point (source and destination) interconnection information. Wiring lists not provided Separate wiring lists are not provided for some assemblies, including: Assemblies that have a separate maintenance manual. Refer to the appropriate maintenance manual for detailed wiring information for these assemblies, if provided. Assemblies that have their wiring information shown in tables on their assembly detail drawings. Refer to the Mechanical Drawings section of this manual for detailed wiring information for these assemblies. Connector mating information Where applicable, a connector mating table is provided after the corresponding wiring list. Table 4. on page 4- identifies all provided connector information. Wire colours Every effort is made to manufacture assemblies using the wire colour shown in the Colour column of the wiring list tables. Sometimes, a white wire will be substituted for the listed colour. In such cases, wires must be identified by their assigned numbers. Printed wiring board patterns Printed wiring pattern information for printed wiring boards (PWBs) is beyond the scope of this manual, and therefore not provided. Issue Page 4-

213 XR6/XR Troubleshooting Manual Reading Electrical Schematics Section 5: Reading Electrical Schematics This section contains electrical schematics and logic diagrams for the XR6/XR transmitter. Block diagrams, simplified electrical schematics, and logic diagrams may be included. Refer to Table 5. on page 5-5 for an itemized listing. Component values Unless otherwise specified on the logic or schematic diagram, the following defaults apply: Resistor values are shown in ohms (k =,000 and M =,000,000) Resistor power ratings are not shown when less than 0.5 W Capacitor values are shown in microfarads (uf) Unidentified diodes are part number N498 Graphic symbols The graphic symbols used on electrical schematics are in accordance with American National Standard ANSI Y Graphic Symbols for Electrical and Electronic Diagrams. Logic symbols The logic symbols used on electrical schematics and logic diagrams are in accordance with American National Standard ANSI Y Graphic Symbols for Logic Diagrams. Reference designations Referenced designations were assigned in accordance with American National Standard ANSI Y Reference Designations for Electrical and Electronic Parts and Equipment. Each electrical symbol is identified with its basic reference designation. To obtain the full reference designation for a specific part, prefix this basic identifier with the reference designation assigned to all higher assemblies. Issue Page 5-

214 XR6/XR Troubleshooting Manual Reading Electrical Schematics Unique symbols Nautel uses unique symbols on electrical schematics to describe logic (two-state) signals. These signals differ from single-state signals or analog signals that may have multiple values. Type of inputs and outputs On electrical schematics, names used to describe logic (two-state) input and output signals are prefixed with a # symbol. Logic level convention The # symbol prefix identifies an input or output signal that has two distinct states: high and low. The suffix on the signal name identifies the active (true) state of the signal. The high (+ suffix) is the more positive of the two levels used to represent the logic states. The low (- suffix) is the less positive of the two levels. Two types of logic, positive and negative, may be represented on a particular schematic. In positive logic, high represents the active (true) state and low represents the inactive (false) state. In negative logic, low represents the active (true) state and high represents the inactive (false) state. Identifying schematic diagrams Each illustration in this section is identified by a number that is both the figure number and the page number. The numbers are assigned sequentially and are prefixed by the letters SD. The electrical schematics and logic diagrams included in this section are listed in Table 5. on page 5-5. Page 5- Issue

215 XR6/XR Troubleshooting Manual Reading Electrical Schematics Structure of schematics The electrical schematics are structured in a hierarchical format that is based on function and signal flow. Wherever practical, the signal flow is from left to right. Normally, inputs originate on the lefthand side and outputs extend to the right-hand side. Exceptions are shown by an arrow indicating the direction of signal flow. Note: The physical location of a part or assembly was not necessarily a factor during creation of the schematic. The full reference designation assigned to a part or assembly, in conjunction with the family tree (see Section, Parts Lists on page -) and the assembly detail drawings (see Section 6, Mechanical Drawings on page 6-), will identify its location. Figures SD- through SD-4 identify each major stage and its detailed interconnection. Each stage contains cross-references that identify which block is the signal source for inputs or the destination for outputs. When a sub-function is treated as a block in Figures SD- through SD-4, its detailed circuit information is included in its own schematic drawing, which is also included in this section. Locating schematic diagram for a functional block The text inside a functional block provides the key to locating its schematic diagram. When a functional block is assigned a reference designation, refer to the family trees in Section, Parts Lists on page -, and follow the family tree branches to the block that contains the reference designation and associated Nautel nomenclature (e.g., NAP4A). Refer to Table 5. with the Nautel nomenclature number and the description to identify the appropriate figure number. Note: Schematics for some functional blocks may consist of more than one figure. Issue Page 5-

216 XR6/XR Troubleshooting Manual Reading Electrical Schematics Locating a part or assembly on a schematic The full reference designation assigned to a part or assembly is the key to physically locating that part or assembly. Note: Full reference designations contain the assembly hierarchical coding. When the end item is divided into units (cabinets), the first coding is a unit number (,,, etc.). When the end item is divided into assemblies, the first coding is an assembly number (A, A, A, etc.). If a unit or an assembly is divided into sub-assemblies, assembly coding that identifies assembly relationship (A, AA, AAA, etc.) is added. Refer to the family trees in Section, Parts Lists on page - with the full reference designation and follow the family tree branches to the appropriate block, noting the name and Nautel nomenclature number of all higher assemblies in the path. Note: The drawings in Section 6, Mechanical Drawings on page 6- depict the assembly detail of the transmitter and its modules and assemblies. Refer to Table 4. with the name and Nautel nomenclature number of each family tree block in the path, starting at the highest assembly (normally Figure MD-). Determine the figure number for that assembly. Refer to the referenced figure and locate the next lower-level assembly. Repeat this procedure until the desired part or assembly is found. Note: Mechanical drawings for some assemblies may consist of more than one figure. Page 5-4 Issue

252 XR6/XR Troubleshooting Manual Mechanical Drawings Section 6: Mechanical Drawings Introduction This section contains mechanical drawings for assemblies of the XR6/XR. Dimensional drawings may be included. Refer to Table 6. for an itemized list. Assembly detail drawings for assemblies and modules that have separate maintenance manuals are not included. Refer to the appropriate maintenance manual for the assembly detail of these assemblies. Locating assembly detail drawings Each illustration in this section is identified by a number that is both the figure number and the page number. The numbers are assigned sequentially and are prefixed by the letters MD. Drawings in this section are listed in Table 6.. Content of mechanical drawings Mechanical drawings are illustrations that depict the location of electrical components and show assembly outline detail. Dimensional information is included, where appropriate. When a module or assembly is the subject of its own assembly detail drawing, and it is also shown in a higher-level assembly, the detail depicted in the higher-level assembly may have minor differences from the module or assembly actually installed. In this case, always refer to the assembly detail drawing of the module or assembly for detailed information. Issue Page 6-
