9 VS2.5 Troubleshooting Manual Responding to alarms Section : Responding to alarms This section provides instructions you need when performing troubleshooting on the VS2.5 transmitter. This section includes the following topics: Corrective maintenance Electrostatic protection - see page -3 Identifying an alarm - see page -4 Troubleshooting tips - see page -26 AUI lockup - see page -26 Operating with defective PAs or cooling fans - see page -27 Replacing a suspect PWB, power supply or fan - see page -28 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 -

10 VS2.5 Troubleshooting Manual Responding to alarms Remote troubleshooting Remote on-air troubleshooting consists of monitoring the transmitter's radiated signal using an on-air monitor or via a LAN connection, 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 a reduced RF output level when a malfunction occurs in one of its power modules. Station operating procedures will dictate whether a reduced RF output level is acceptable. When a reduced RF output level can be tolerated, replacement of the defective RF components may be deferred to a convenient time. Off-air troubleshooting Off-air troubleshooting must be performed routine on-air calibration adjustments will not restore operation. It is recommended that the transmitter s output be connected to a precision 50 resistive dummy load (rated for at least the maximum transmitter power rating of 2500 W) before starting off-air troubleshooting procedures. If an appropriate dummy load is not available, troubleshooting for a majority of faults can be performed with the RF power stage turned off. The transmitter may remain connected to its antenna system for these procedures. CAUTION: Reduce the RF output level to a minimal value when troubleshooting faults in the transmitter. This is particularly important when the transmitter s cover is removed - where possible overheating could occur - or when the transmitter is connected to the antenna system. Page -2 Issue

11 VS2.5 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 (i.e., grounded tip) 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.

12 VS2.5 Troubleshooting Manual Responding to alarms Identifying an alarm You can identify an alarm locally by viewing the front panel (see Front panel alarm checks ) or remotely by viewing the AUI s Transmitter Status page (see AUI Transmitter status page checks on page -6). Front panel alarm checks There two ways to check for alarms on the front panel: Alarm/status LEDs View alarms screen - see page -5 Alarm/status LEDs There are four LEDs on the left-hand side of the LCD display that provide information about the operational status of various sections of the transmitter - Exciter, Power Amplifier, Output Network and Power Supply (see Figure.). The LEDs can glow green, amber or red. Typically, green indicates normal operation, amber indicates a warning, and red indicates a fault or error. Figure.: Alarm/Status LEDs Exciter Power Amplifier Output Network Power Supply When an LED is: green - transmitter is on, with no known faults. amber - a fault is present that may cause a reduction in RF power, but the transmitter is still producing RF power. red - a fault is present and the transmitter is not producing RF power. When a fault is present, the transmitter may still produce an RF output. In this case, or if the transmitter has shut down, you should schedule and commence more in-depth fault diagnosis. See View alarms screen on page -5. Page -4 Issue

13 VS2.5 Troubleshooting Manual Responding to alarms View alarms screen If an alarm exists and is currently being recognized by the transmitter system, it is displayed in the View Alarms screen (Main Menu -> View Status -> View Alarms) of the front panel Display (see Figure.2).

19 VS2.5 Troubleshooting Manual Responding to alarms Alarm Name AUI and (Front Panel) All Power Amplifiers Inactive (All PAs Inactive) Analog Left Low (Anlg Left Aud Low) Analog Right Low (Anlg Right Aud Low) Front Panel LED (color) PA (red) Exciter (amber) Exciter (amber) Description and Troubleshooting Action This alarm indicates that all of the PAs in the system or all of the power supply modules in the system have failed simultaneously; therefore PA failure alarms or power supply module related alarms should also be present. If there are power supply module related alarms present, or an IPA Output Low alarm, follow the associated troubleshooting procedure. If there are no power supply module related alarms, with RF turned on, use a digital multimeter to measure the voltage between pad V and pad W on any PA. If the voltage does not fall within an acceptable range (between 2.3 V and 3 V), suspect the exciter/control PWB (A). If the voltage does fall in the acceptable range, perform the PA resistance checks on page -3. If there is no problem found with any of the PAs, or the alarm still persists after replacing all of the damaged PAs, suspect the PS distribution PWB (A2). This alarm indicates the analog left audio input level is too low or is not applied. The VS2.5 takes no action on this alarm. This alarm indicates the analog right audio input level is too low or is not applied. The VS2.5 takes no action on this alarm. Audio Loss Exciter (red) This alarm, enabled by the user, indicates that the exciter s audio modulation level is below the level specified in the mod loss settings of the active preset [see page 2-72 (remote AUI) or Mod Loss on page 2-93 (front panel UI)] of the Operations and Maintenance Manuals to enable/disable this alarm and to configure the resulting action). Depending on the setting, this alarm could trigger a preset change, inhibit RF or have no effect (alarm only). Check the appropriate program input(s) and the mod loss setting for the preset. Audio Loss Summary Audio Processor Offline Exciter (red) Exciter (amber) Not displayed in AUI or UI status. This alarm occurs if there are any audio loss alarms present. Check for specific audio loss alarms and troubleshoot accordingly. Ensure the preset audio settings agree with the audio being applied to the exciter. This alarm occurs if the exciter is configured to include an Orban Inside audio processor, but it is not communicating with the processor on the internal serial bus. Check all connections to the Orban Inside audio processor card. Issue Page -

20 VS2.5 Troubleshooting Manual Responding to alarms Alarm Name AUI and (Front Panel) Audio Processor Output Fail Audio Shutdown Composite Low (MPX Aud Low) CPLD Version Mismatch (CPLD Ver Mismatch) Cutback Active Digital Low (Digital Aud Low) Front Panel LED (color) Exciter (amber) Exciter (red) Exciter (amber) Exciter (red) Output Network (amber) Exciter (amber) Description and Troubleshooting Action This alarm occurs if the exciter is configured to include an Orban Inside audio processor, but it is not detecting audio from the processor. Check all connections to the Orban Inside audio processor card. This alarm occurs if the exciter s audio processing and FM modulation code is shut down. Should display only during a software upgrade. This alarm indicates the composite audio input level is too low. The VS2.5 takes no action on this alarm. This alarm indicates that the CPLD version installed on the transmitter does not match the version expected to be seen by the version of code installed on the DSP. The VS2.5 will not be able to turn RF on. Contact Nautel for further assistance. This alarm occurs whenever the transmitter experiences a cutback. A cutback (reduction in power) occurs when repeated shutback alarms occur within a prescribed time period. Shutbacks occur when the transmitter's peak reflected power exceeds 2: due to a transient SWR condition (arc or lightning) within the output transmission line or antenna system. The transmitter shuts back and recovers to a series of cutback levels (depending on the severity of the alarm), with each level being a /8th reduction in power from the previous cutback level, starting from the preset setpoint. Inspect the output transmission line for punctures or damage. After repairing damage, or if no damage is found, attempt to reset the latched condition [using the remote AUI s Reset button (see Reset: on page 2-4 of the Operations and Maintenance Manual) or using the local front panel display (see Resetting alarms on page 2-67 of the Operations and Maintenance Manual)]. If no damage can be found, suspect a fault with the combiner interface PWB (A2) (see Combiner Interface PWB Replacement on page -44). This alarm indicates the corresponding digital input level is too low and is typically accompanied by a SRC Unlock alarm (see its description and troubleshooting action). If no accompanying SRC alarm exists, suspect a problem with the external audio processor or studio feed. The VS2.5 takes no action on this alarm. Page -2 Issue

21 VS2.5 Troubleshooting Manual Responding to alarms Alarm Name AUI and (Front Panel) Discharging PA Volts (Discharging PA V) Entered Firmware Upgrade (Exc Firmware Upgr) Front Panel LED (color) PS (red) Exciter (red) Description and Troubleshooting Action This alarm occurs when the transmitter has initiated a shutback sequence, and residual PA voltage energy stored in the capacitors in the power supplies and PAs is being discharged. During a shutback sequence, the RF drive to the PAs is turned off immediately after the event, and this occurs faster than the power supply modules can be inhibited. Therefore, PA voltage is still being applied to the capacitors with no drive to discharge the energy. To discharge the stored energy from the capacitors, the PA bias is increased to a discharge level after the power supplies have been inhibited. This causes the stored energy to be dissipated through dc current in the FET. This alarm should only occur with a Residual PA Volts Present alarm. See Residual PA Volts Present alarm for more information. This alarm occurs when the exciter is in firmware upgrade mode. It should only be displayed during a transmitter software upgrade. Exciter Offline Exciter (red) For use with VS-HD exciter only. This alarm occurs if the serial communication fails between the controller and the exciter, or a problem has occurred with the exciter. Check all connections to the exciter and make sure that its controller front panel power LED is on. Exciter Summary External Interlock Open (External Interlock) Exciter (amber) Exciter (red) Not displayed in AUI or UI status. This alarm occurs if there are any exciter related alarms present. Check for specific exciter related alarms. This alarm occurs when the external interlock input wired to the exciter/control PWB (A) is open. The VS2.5 will not be able to enable its RF output. Check the interlock connection between AJ2A-9 and AJ2A-20 on the rear of the transmitter. If the interlock connection is intact, check that all external interlock switches are closed. If no problem is found with the connection at the transmitter or any of the external interlock switches, suspect a problem with the interlock circuitry on the exciter/control PWB (A). External Summary - Not displayed in AUI or UI status. This alarm occurs if there are any external related alarms present. Check for specific external related alarms and troubleshoot accordingly.

22 VS2.5 Troubleshooting Manual Responding to alarms Alarm Name AUI and (Front Panel) Fan - 7 Fail Forward Power Limiting (Fwd Power Limiting) Forward Power Low (Fwd Power Low) Front Panel LED (color) Output Network (amber) Output Network (amber) Output Network (amber) Description and Troubleshooting Action This alarm occurs if the speed of one of the transmitter's cooling fans is below 3000 RPM (half of its nominal value of 6000 RPM). If any of fans 3 through 7 fail, the VS2.5 will reduce its maximum power setting based on the number of fan failures that have occurred (see Table.2 on page -27). If either fan or 2 fail, the VS2.5 takes no action (no effect on the RF output). If the alarm occurs for fans or 2, check the connection between the indicated fan and the PS distribution PWB (A2). If the alarm occurs for fans 3, 4, 5, 6 or 7, check the connection between the indicated fan and the splitter PWB (A4). If these connections look OK, replace the indicated fan (see Cooling fan replacement - fans 3 (B3) through 7 (B7) on page -36). If the alarm still occurs after the fan has been replaced, suspect the PS distribution PWB for fans or 2 and suspect the exciter/control PWB (A) for fans 3 through 7. When the High Forward Power alarm is active, the Forward Power Limiting alarm occurs if its associated threshold is exceeded (.063 times the maximum power setting; 2976 W). The transmitter will fold back the forward power each time the threshold is exceeded. This alarm occurs only if the exciter ALC cannot respond fast enough to transmitter load changes. Inspect the antenna network attached to the transmitter. If there are no major issues with the antenna network that would cause an impedance change (icing for example) suspect the combiner interface PWB (A2) (see Combiner Interface PWB Replacement on page -44). This alarm occurs if the transmitter's average forward power falls below the low forward power threshold (defaulted to 50% of the preset power level and is user adjustable) due to PA failures, fan failures, SWR foldback or a pre-amp/ipa failure. The VS2.5 takes no action on this alarm. Check for associated alarms, and follow the associated troubleshooting procedure if present. If no other alarms are being indicated, with RF turned on, use a digital multimeter to measure the voltage between pad V and pad W on any PA. If the voltage does not fall within an acceptable range (between 2.3 V and 3 V), suspect the exciter/control PWB (A). If the voltage is within this range, suspect the combiner interface PWB (A2) (see Combiner Interface PWB Replacement on page -44). Page -4 Issue

23 VS2.5 Troubleshooting Manual Responding to alarms Alarm Name AUI and (Front Panel) Forward Power Shutdown (Fwd Power Shutdown) Forward Power Very Low (Fwd Power Very Low) Front Panel LED (color) Output Network (red) Output Network (amber) Description and Troubleshooting Action This alarm occurs if the transmitter tries to reduce the forward power below minimum (64 W) due to repeated Forward Power Limiting alarms. The transmitter latches off. See Forward Power Limiting for troubleshooting tips. This alarm occurs if the transmitter's average forward power falls below the very low forward power threshold (defaulted to 2.5% of the preset power level and is user adjustable) due to PA failures, fan failures, or SWR foldback. The VS2.5 takes no action on this alarm. See Forward Power Low for troubleshooting tips. HD Summary - For use with VS-HD exciter only. Check for related HD alarms and troubleshoot accordingly. High Forward Power (High Fwd Power) High Reject Power High Reflected Power Output Network (amber) Output Network (amber) Output Network (amber) This alarm occurs if the transmitter's average forward power exceeds the high forward power threshold (.036 times the maximum power setting; 290 W). This alarm occurs only if the exciter ALC cannot respond fast enough to transmitter load changes. The VS2.5 takes no action on this alarm. Check for associated alarms and follow the associated troubleshooting procedure, if present. If no other alarms exist, inspect the antenna network attached to the transmitter. If there are no major issues with the antenna network that would cause an impedance change (icing for example) suspect the combiner interface PWB (A2) (see Combiner Interface PWB Replacement on page -44). This alarm occurs if the control system determines that the calculated power in any reject resistor exceeds the high reject power threshold (320 W). The VS2.5 takes no action on this alarm. Check for associated alarms, and follow the associated troubleshooting procedure if present. Typically, high reject power is the result of a PA failure or removal. If no other alarms are being indicated, contact Nautel for further support. This alarm occurs if the transmitter's average reflected power exceeds the high SWR threshold (72 W). The VS2.5 takes no action on this alarm. Inspect the antenna and transmission line system for damage or de-tuning. If there are no major issues with the antenna network that would cause an impedance change (icing for example), suspect the combiner interface PWB (A2) (see Combiner Interface PWB Replacement on page -44). Issue Page -5

24 VS2.5 Troubleshooting Manual Responding to alarms Alarm Name AUI and (Front Panel) High Reflected Summary High SWR Shutdown Front Panel LED (color) Output Network (amber) Output Network (red) Description and Troubleshooting Action Not displayed in AUI or UI status. This alarm occurs if thereare alarms present that are related to high reflected power on the transmitter s RF output. Check for specific reflected power related alarms and troubleshoot accordingly. This alarm occurs if the transmitter tries to reduce the forward power below a level that is equivalent to a 3: VSWR (forward power of 42 W) at the SWR Foldback threshold (reflected power of 03 W) due to a gradually degrading load match. This alarm causes the transmitter to latch off. Inspect the antenna and transmission line system for damage or de-tuning. If there are no major issues with the antenna network that would cause an impedance change (icing for example), suspect the combiner interface PWB (A2) (see Combiner Interface PWB Replacement on page -44). High Temperature Summary - Not displayed in AUI or UI status. This alarm occurs if there are high temperature related alarms occurring. Check for specific temperature related alarms and troubleshoot accordingly. Host Network Down Host Not Booted Exciter (amber) Exciter (amber) This alarm indicates that the microcontroller that runs the remote interfacing applications is unable to acquire an IP address. When this alarm is present, the communication between the LAN controller (server) and the transmitter server that was once established has now been lost. It will not be possible to access any of the remote AUI functionality. Check that the Ethernet cable is properly connected to AJ8A (LAN) on the rear of the transmitter.

26 VS2.5 Troubleshooting Manual Responding to alarms Alarm Name AUI and (Front Panel) IPA Output Low Front Panel LED (color) PA (red) Description and Troubleshooting Action This alarm occurs if the pre-amp/ipa PWB's (A5) forward power is less than the IPA Output Low threshold (4.4 W). This alarm causes the controller to limit the PA voltage to 30 V. Check for a +48V Supply Fail alarm and follow the associated troubleshooting procedure if present. IPA Fail and Pre-amp Fail alarms may also be present. If no associated alarms are present, turn RF off and run the bias routine in the front panel s Main Menu -> System Settings -> Calibration menu. If the alarm persists, enable RF and use a digital multimeter to measure the voltage between pad B on pre-amp/ipa PWB (pre-amp bias) and chassis (ground) and also between pad C on pre-amp/ipa PWB (IPA bias) and chassis (ground). If the voltage is less than V at either of these points, suspect the exciter/control PWB (A). If the voltage is greater than V at both of these points, use a digital multimeter to measure between pad E (IPA volts) on the pre-amp IPA PWB and chassis (ground). If the measured voltage is not within an acceptable range (between +43 V and +48 V), with ac power off, perform a continuity check across F of the PS distribution PWB (A2). If the measurement is greater than, replace the fuse (Nautel Part # FA57 in the ancillary kit). If the measurement is less than, or replacing the fuse does not clear the alarm, replace the pre-amp/ipa PWB (A5) (see Pre-amp/IPA PWB replacement on page -3). If the voltage on pad E is acceptable, use a digital multimeter to measure between pad D (pre-amp volts) on the preamp IPA PWB and chassis (ground). If the measured voltage is not within an acceptable range (between +43 V and +48 V), replace the pre-amp/ipa PWB (A5) (see Pre-amp/IPA PWB replacement on page -3). If the voltage is acceptable, or replacing the pre-amp/ipa PWB does not clear the alarm condition, suspect the combiner interface PWB (A2) (see Combiner Interface PWB Replacement on page -44) or the exciter/control PWB (A) (see Exciter/Control PWB Replacement on page -40). Low Battery Exciter (amber) This alarm occurs if the backup battery voltage falls below an acceptable level (2.7 V). The VS2.5 takes no action on this alarm.

PA - 4 Fail PA (amber) This alarm occurs if the dc input current for the indicated PA has fallen below a predetermined threshold (typically less than 50% of the average PA current of the operational PAs, or below 500 ma, whichever is lower). This may be caused by a cabling fault on the PA, loss of PA voltage or bias, or a defective FET. The transmitter's output power will be reduced (see Table.2 on page -27) and this condition could cause Per PA Foldback and Reject Foldback alarms. Check for an All Power Amplifiers Inactive alarm and follow the associated troubleshooting procedure if present. If the All Power Amplifiers Inactive alarm is not present, perform the PA resistance checks on page -3. If there is no problem found with the PAs, or the alarm still persists after replacing the PA, suspect the PS distribution PWB (A2). Page -20 Issue

The VS2.5 will reduce its maximum power if only one power supply module failed (see Table.2 on page -27). Check the ac voltage applied to the power supply module. If the ac voltage is acceptable, try replacing the indicated power supply module with a new module, or changing the position of the indicated power supply within the transmitter (see Power Supply Module Replacement on page -34). If the fault moves with the power supply module, replace the power supply module. If the fault does not move with the power supply module, or if replacing it with a new power supply module does not clear the fault, suspect the PS distribution PWB (A2). PS A (or B) Fail PS (amber) This alarm occurs if power supply module A (U) or B (U2) is reporting a PS failure, indicating its output voltage is outside of its acceptable range. The VS2.5 will reduce its maximum power if only one power supply module failed (see Table.2 on page - 27). Try replacing the indicated power supply module with a new module, or changing the position of the indicated power supply within the transmitter (see Power Supply Module Replacement on page -34). If the fault moves with the power supply module, replace the power supply module. If the fault does not move with the power supply module, or if replacing it with a new power supply module does not clear the fault, suspect the PS distribution PWB (A2) or the exciter/control PWB (A).

The VS2.5 will reduce its maximum power if only one power supply module failed (see Table.2 on page -27). If there is a power supply module in the position being indicated by the alarm, try replacing the indicated power supply module with a new module, or changing the position of the indicated power supply within the transmitter (see Power Supply Module Replacement on page -34). If the fault moves with the power supply module, replace the power supply module. If the fault does not move with the power supply module, or if replacing it with a new power supply module does not clear the fault, suspect the PS distribution PWB (A2). This alarm occurs if power supply module A (U) or B (U2) is reporting a high temperature alarm, indicating its operating temperature has exceeded its internal threshold. The VS2.5 will reduce its maximum power if only one power supply module failed (see Table.2 on page -27). This alarm is most likely caused by a module fan failure or blockage. Allow the module to cool and attempt to reset the alarm. Verify the module turns on and its fan is operational. If the fan is not operational, inspect it for possible blockage. If a problem is found, replace the power supply module (see Power Supply Module Replacement on page -34). If there is no problem found, inspect the transmitter s air filter and clean or replace as required (see Section 3, Routine maintenance of the Operations and Maintenance Manual). If the alarm persists, try replacing the indicated power supply module with a new module, or changing the position of the indicated power supply within the transmitter (see Power Supply Module Replacement on page - 34). If the fault moves with the power supply module, replace the power supply module. If the fault does not move with the power supply module, or if replacing it with a new power supply module does not clear the fault, suspect the PS distribution PWB (A2). This is an informational alarm only that is displayed when the watchdog timer reboots the transmitter s main microcontroller (DSP). Typically, this alarm will show up after an ac power interruption. This alarm indicates that exciter setup changes have been made, typically via the Hardware Configuration page of the AUI. Typically, the DSP will reboot itself automatically; however, if this alarm persists for more than five minutes, cycle the transmitter s ac power (off, then on) to store the changes. Issue Page -23

This alarm occurs if there are any alarms present that caused the transmitter s RF output power to be reduced. Check for associated alarms, and follow the associated troubleshooting procedure, if present. This alarm occurs if the control system determines that the calculated power in any reject resistor exceeds the reject power foldback threshold (400 W). The forward power of the transmitter will be limited to a level such that this threshold is not exceeded. This alarm should be accompanied by a High Reject alarm. Check for other associated alarms, and follow the associated troubleshooting procedure if present. Typically, high reject power is the result of a PA failure or removal. If no other alarms are being indicated, contact Nautel for further support. This alarm occurs if the control system determines that the calculated power in any reject resistor exceeds the reject power shutback threshold (480 W). This alarm will initiate an immediate shutdown of the transmitter's RF output. The transmitter will then attempt to turn RF on and increase the forward power of the transmitter to a level such that the reject foldback threshold is not exceeded. This alarm should be accompanied by a High Reject alarm and possibly a Reject Foldback alarm. Check for other associated alarms, and follow the associated troubleshooting procedure if present. Typically, a reject shutback is the result of a sudden PA failure. If no other alarms are being indicated, contact Nautel for further support. This alarm indicates that after the transmitter has turned off its RF output, it is unable to discharge the PA volts to a level that is below 3 V. This condition will not allow the transmitter to turn on its RF output; however the condition will be cleared once the PA volts reaches a level that is below 3 V. This condition will typically occur with a failed PA or power supply module. Check for associated alarms and follow the associated troubleshooting procedure, as applicable. If no associated alarms are present, suspect the PS distribution PWB (A2) or the exciter/control PWB (A).

SWR Foldback SWR Shutback Unsigned DSP Image (Exc Bad DSP Image) Output Network (amber) Output Network (red) Exciter (red) This alarm occurs if the transmitter's average reflected power exceeds the SWR foldback threshold (03 W) due to a gradually degrading load match. The forward power of the transmitter will be limited to a level such that this threshold is not exceeded. If the load match improves while the transmitter is producing RF output, the forward power will increase. If the transmitter folds back to a forward power that is equivalent to a 3: VSWR at the SWR Foldback threshold (forward power of 42 W), an SWR Shutdown alarm occurs. Inspect the antenna and transmission line system for damage or de-tuning. If there are no major issues with the antenna network that would cause an impedance change (icing for example), suspect the combiner interface PWB (A2) (see Combiner Interface PWB Replacement on page -44). This alarm occurs if the transmitter's reflected power suddenly exceeds the SWR shutback threshold, which is the reflected power that is equivalent to a 2: VSWR at max power (3 W) due to a transient SWR condition (arc or lightning) within the output transmission line or antenna system. Attempt to reset the latched condition by pressing Reset [using the remote AUI s Reset button (see Reset: on page 2-4 of the Operations and Maintenance Manual) or using the local front panel display (see Resetting alarms on page 2-67 of the Operations and Maintenance Manual)]. Inspect the output transmission line for punctures or damage. If no damage can be found, suspect the combiner interface PWB (A2) (see Combiner Interface PWB Replacement on page -44). See also Cutback Active alarm. This alarm indicates that the exciter is operating with unsigned code, but is otherwise operational. This alarm may only be displayed if the transmitter is operating with a beta version of factory software. Issue Page -25

54 VS2.5 Troubleshooting Manual Detailed Circuit Descriptions PS distribution PWB (NAPS53) See electrical schematic Figure SD-3. Interfacing The PS distribution PWB provides the interface between the VS2.5 s power supplies and the rest of the transmitter. It passes: ac voltage from the AC INPUT (U) to the power supply modules (U and U2). PA voltage from the power supply module U to power amplifier (PA) PWBs (A6 and A8). PA voltage from the power supply module U2 to power amplifier (PA) PWBs (A7 and A9). Pre-amp voltage (+48 V) from the +48 V power supply (U4) to the pre-amp/ipa PWB (A5) [pre-amp V delivered via the exciter/control PWB (A) and the interface PWB (A3)]. Power supply control voltage and power supply inhibit signal from the exciter/control PWB (A) to the power supply modules (U and U2). Power supply monitoring A 0-bit ADC IC U9 accepts several power supply related inputs (PA volts, PA current, pre-amp current, IPA current, +48 V, +5 V and +5 V) and converts them to a digital data stream on the MISO ADC output (J7-2). This output is applied to the exciter/control PWB for monitoring and protection purposes. Power supply module fault monitoring Two 8-bit shift register ICs, U4 and U5, accept the status and alarm signals from the power supply modules (U and U2) (PS present, PS ac fail, PS temp and PS fail) and converts them to a serial data stream on the MISO 65 output (J7-4). This output is applied to the exciter/control PWB for monitoring and protection purposes. If a power supply module fault occurs, the exciter/control PWB will inhibit the power supply module via the # 595 CS - input (J7-6). Fan enable Transistor Q3, FET Q2 and associated components form a fan enable circuit that controls the application of power supply voltage (+48 V) to the cooling fans (B through B7). When the transmitter s RF status is on, the Fan Enable input (J6-2) is logic high and transistor Q3 turns on. This causes FET Q2 to turn on, allowing +48 V to be applied to the Fan V (+) outputs (J6-, 2 and 3), enabling fans B3 through B7, and to the Fan V (+) (J4-3) and Fan 2 V (+) outputs (J5-3), enabling the power supply module fans. When the transmitter s RF status is off, transistor Q3 turns off. This causes FET Q2 to turn off, preventing +48 V from being applied to all Fan V (+) outputs; hence disabling the fans. Page 2-2 Issue

55 VS2.5 Troubleshooting Manual Detailed Circuit Descriptions Fan monitoring 8-bit shift register IC U5 accepts the fan tach signals from fans B and B2 and converts them to a serial data stream on the MISO 65 output (J7-4). This output is applied to the exciter/control PWB for monitoring purposes. LVPS Two +48 V to +5 V dc-dc converters (U6 and U7) and their associated components generate the +5 V rail that is applied to circuitry throughout the transmitter. A +48 V to +5 V converter (U) and its associated components generate the +5 V that is applied to the exciter/control PWB. Pre-amp/IPA PWB (NAPA28B) See electrical schematic Figure SD-4. The pre-amp/ipa PWB (A5) accepts the RF output of the exciter/control PWB (A), or external source, and amplifies it to an intermediate RF drive level for application to the PA PWBs (A6 through A9) via the splitter PWB (A4). The pre-amp/ipa PWB contains two N-channel FETs (Q and Q2) and associated components configured as a two-stage RF power amplifier. The RF output is generated by the Pre-amp V and IPA V levels provided by the PS distribution PWB (A2), and the Preamp Bias and IPA Bias outputs from the exciter/control PWB (A). The RF output level is controlled by the RF input level generated by the exciter/control PWB. Cooling air for the pre-amp PWB is provided by fan B. The RF Drive input is applied to the gate of FET Q through a series of micro-strip transmission line sections and capacitors C and C2 and inductor L, which provide impedance matching to transform the 50 ohm input to low impedance for application to Q. Additional micro-strip transmission line sections at the output of Q, as well as inductors L8 and L9 and capacitors C6 and C7, impedance match the Q output signal to 50 ohms. The impedance matched output of Q is applied to the gate of FET Q2 through a series of micro-strip transmission line sections and associated components, including capacitor C8 and inductor L0, which provide impedance matching to transform the 50 ohm input to low impedance for application to Q2. Additional micro-strip transmission line sections at the output of Q2, as well as inductors L6 and L7 and capacitors C25 through C27, impedance match the RF Output signal to 50 ohms.. The Pre-amp V input is applied to capacitors C29, C0, C and C2, which act as a broadband decoupling network. Capacitor C5 and inductors L5 and L7 provide low-pass filtering of the RF signal back to the ac-dc power stage. Issue Page 2-3

56 VS2.5 Troubleshooting Manual Detailed Circuit Descriptions The IPA V input is applied to capacitors C9, C2, C22 and C24, which act as a broadband decoupling network. Capacitor C23 and inductors L4 and L5 provide low-pass filtering of the RF signal back to the ac-dc power stage. The Pre-amp Bias input voltage is provided by the exciter/control PWB to establish a dc bias current for Q. The IPA Bias input voltage is provided by the exciter/control PWB to establish a dc bias current for Q2. Power amplifier PWB (NAPA3C) See electrical schematic Figure SD-5. Each power amplifier (PA) PWB (A6 through A9) accepts the RF output of the pre-amp/ipa PWB (A5), which has been split four ways by the splitter PWB (A4), and amplifies it to its RF output level. Each PA PWB is a push-pull, RF power amplifier that is capable of providing 850 W of RF power in the FM broadcast band (87.5 to 08.0 MHz). The RF output is controlled by the PA V level generated by the power supply modules, the PA Bias output from the exciter/control PWB (A), and the RF drive level generated by the IPA PWB. Cooling air for the PA PWBs is provided by fans B3 through B7. The RF Drive input is applied to transformer T3, which is connected as a balun to provide balanced, 80 out-of-phase, RF drive signals to the individual gates of dual N-channel power MOSFET (Q). Inductors L, L2 and L3, capacitor C8 and transformer T3 provide impedance matching, which transforms the 50 ohm input to low impedance for application to Q. The PA voltage is applied to the individual drains of Q via transformer T2, which, along with capacitors C4 and C5, cable T and inductor L4, transforms the impedance at the RF output, ensuring an optimum (low) impedance is presented at Q's output. Cable T converts the balanced RF signal to an unbalanced RF Output signal. Capacitors C8, C0, C2 and C9 are used as dc blocking capacitors. The PA V input is applied to capacitors C, C2, C3, C4, C5, C9, C, C3, C7, C2 and C22, which act as a broadband decoupling network. Capacitor C20 and resistors R4 and R5 provide low-pass filtering of the RF signal back to the ac-dc power stage. The PA Bias input voltage is provided by the exciter/control PWB to establish a dc bias current for Q. The bias current depends on the operating mode. The PA Bias voltage is applied to a low-pass filter circuit, formed by resistor R3 and capacitor C6, and is then applied to a voltage divider formed by resistors R3 and R. Diodes CR and CR2 prevent the bias voltage from dropping below -6 V and damaging the FET. Page 2-4 Issue

137 VS2.5 Troubleshooting Manual Reading Electrical Schematics Section 5: Reading Electrical Schematics This section contains electrical schematics and logic diagrams for the transmitter. Block diagrams, simplified electrical schematics, and logic diagrams may be included. Refer to Table 5. on page 5-4 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 N4938 (Nautel Part # QAP29) 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. For example, the complete designation for a resistor (R) on a printed wiring board (A), that is part of a larger board (A2), would be A2AR. Issue Page 5-

138 VS2.5 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 # prefix identifies an input or output signal that has two distinct states: high and low. The suffix on an input or output signal name identifies the active (true) state of the signal. The high suffix (+) indicates the more positive of the two levels used to represent the logic states. The low suffix (-) indicates 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 electrical schematic in this section is identified by a number that is both the figure number and the page number. The numbers are assigned sequentially are prefixed by the letters SD. The electrical schematics and logic diagrams included in this section are listed in Table 5. on page 5-4. 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 3, Parts Lists on page 3-) and the assembly detail drawings (see Section 6, Mechanical Drawings on page 6-), will identify its location. Page 5-2 Issue

139 VS2.5 Troubleshooting Manual Reading Electrical Schematics Figures SD- and SD-2 identify each major stage and its detailed interconnection. Each stage contains cross-references that identify which blocks are the signal sources for inputs, or the destinations for outputs. When a sub-function is treated as a block in figures SD- and SD-2, its detailed circuit information is included in its own schematic drawing(s), which is also included in this section. Locating schematic diagram(s) for a functional block The text inside a functional block provides the key to locating its schematic diagram(s).. When a functional block is assigned a reference designation (e.g., A2A), refer to the family trees in Section 3, Parts Lists on page 3-. Follow the family tree branches to the block that contains the desired reference designation, and associated Nautel nomenclature (e.g., NAPA3C PA PWB). Note the reference designations and Nautel nomenclatures of all higher assemblies in the path, if applicable. Example: A6 NAPA3C PA PWB. 2. Refer to Table 5. on page 5-4 and use the reference designation and Nautel nomenclature to identify the appropriate schematic diagram(s). Example: NAPA3C PA PWB is shown on schematic SD If necessary, refer to the referenced figure in the schematics at the end of this section and locate the next, lower-level assembly. Then, repeat this procedure until the desired schematic diagram is found. 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 (, 2, 3, etc.). When the end item is divided into assemblies, the first coding is an assembly number (A, A2, A3, etc.). If a unit or an assembly is divided into sub-assemblies, assembly coding that identifies assembly relationship (A, A2A, A2AA, etc.) is added.. Refer to the family trees in Section 3, Parts Lists on page 3-. Issue Page 5-3

140 VS2.5 Troubleshooting Manual Reading Electrical Schematics 2. Follow the family tree branches to the block that contains the desired reference designation, while noting the Nautel nomenclatures and names of all higher assemblies in the path, as applicable. Example: A5 NAPA3C PA PWB. Note: The drawings in the Mechanical Drawings section depict the assembly detail of the transmitter and its modules and assemblies. 3. Refer to Table 6. in Section 6, Mechanical Drawings on page 6-. Use the Nautel nomenclature and name of each family tree block in the path, starting at the highest assembly this is normally Figure MD- to determine the figure number(s) for that assembly.

148 VS2.5 Troubleshooting Manual Mechanical Drawings Section 6: Mechanical Drawings This section contains mechanical drawings for assemblies of the transmitter. Dimensional drawings may be included. Refer to Table 6. on page 6-2 for an itemized list. Assembly detail drawings for assemblies and modules that have separate manuals are not included. Refer to the appropriate maintenance manual for the assembly detail of these assemblies. Identifying mechanical drawings Each mechanical drawing 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. on page 6-2. 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. Locating a part or assembly on a mechanical drawing. When a part or assembly is assigned a reference designation (e.g., A2 or A2R), refer to the family trees in Section 3, Parts Lists on page 3-. Follow the family tree branches to the block that contains the desired reference designation and Nautel nomenclature (e.g., NAPA3C PA PWB). Note the reference designations and Nautel nomenclatures of all higher assemblies in the path, as applicable. Example: A6 NAPA3C PA PWB. 2. Refer to Table 6. on page 6-2. Use the reference designation and Nautel nomenclature to identify the appropriate mechanical drawing. Example: NAPA3C PA PWB is shown on schematic MD-7. Issue Page 6-

149 VS2.5 Troubleshooting Manual Mechanical Drawings 3. If necessary, refer to the referenced figure (e.g., MD-7) in the mechanical drawings at the end of this section and locate the next, lower-level assembly.
