Unpacking Relays must only be handled by qualified personnel and special care must be taken to protect all of their parts from any damage while they are being unpacked and installed. The use of good illumination is recommended to facilitate the equipment visual inspection. The facility must be clean and dry and relays should not be stored in places that are exposed to dust or humidity. Special care must be taken if construction work is taking place Reception of relays It is necessary to inspect the equipment at the time it is delivered to ensure that the relays have not been damaged during transport. If any defect is found, the transport company and FANOX should be informed immediately. If the relays are not for immediate use, they should be returned to their original packaging Handling electronic equipment Relays contain an electronic component that is sensitive to electrostatic discharges. Just by moving, a person can build up an electrostatic potential of several thousand volts. Discharging this energy into electronic components can cause serious damage to electronic circuits. It is possible that this damage may not be detected straight away, but the electronic circuit reliability and life will be reduced. This electronic component in the equipment is well protected by the plastic housing, which should not be removed as the equipment cannot be adjusted internally Installation, commissioning and service The personnel in charge of installing, commissioning and maintaining this equipment must be qualified and must be aware of the procedures for handling it. The product documentation should be read before installing, commissioning or carrying out maintenance work on the equipment. In order to guarantee safety, the crimp terminal and a suitable tool must be used to meet isolation requirements on the terminal strip. Crimped terminations must be used for the voltage and current connections. Before supplying the equipment the value of the rated voltage and its polarity must be checked. The equipment must be used within the stipulated electrical and environmental limits. NOTE: Current transformer circuits: Do not open a live CT secondary circuit. The high voltage produced as a result could damage the isolation and threaten lives. 6/128

7 1.5. Storage If the relays are not going to be installed immediately, they must be stored in a dust- and humidity free environment after the visual inspection has been performed Recycling All electrical power sources should be removed before performing this operation to avoid the risk of electrical discharge. This product must be disposed of in a safe way. It should not be incinerated or brought into contact with water sources like rivers, lakes, etc 7/128

15 3. DESCRIPTION 3.1. Introduction Industrial company management is gradually increasing its use of information technology and communication as the basis for predictive maintenance and monitoring of their facilities. This ever increasing technology implies a technological leap for industries, as it requires the handling of a larger amount of data, and in many occasions in real time. To implement these new technologies the industries require simple, flexible systems which adapt to the specific requirements of the same. These requirements include: Simple controls. Simple installation. Large volume of data Real time. Reasonable cost. System profitability, understood as maintenance and monitoring. The PBM is a motor control and protection system equipped with ModBus RTU communication in real time RS485. This makes up a platform which is specifically designed to cover all the maintenance and monitoring requirements of industrial plants with motors. The PBM devices structure is based on a base module which, according to the requirements, can be connected to various modules with specific functions. The PBM B base module (DIN rail EN ), with the following functions: Motor related current protections. Temperature protection. Earth protections. Trip and signalling. Communications with the scada. Fault reports. Statistics. The PBM H module, is an HMI module (panelable) to access the PBM B information. The system functions can be increased in the future with additional modules. 15/128

19 ACCESSORIES Toroidal transformer Current transformer PTC sensors Cables section PBM-B to PBM-H connection cable 3.2. Description The PBM is a three phase motor control and protection system. It includes the motor current and thermal protections, as well as the monitoring and diagnosis functions to perform predictive maintenance and to prevent system down times. The base module is the essential components of the PBM system. This must always be included and provide basic system protection on its own. The base module is a 78 mm item to be mounted on a DIN rail. The available protection functions are as follows: Overload protection and availability of a PTC sensor. Protection against imbalance, phase failure and phase reversal Protection against jam, locked rotor and undercurrent. Earth protection: Instantaneous neutral overcurrent, neutral inverse time overcurrent, instantaneous earth leakage overcurrent, earth leakage inverse time overcurrent. 19/128

20 To facilitate predictive maintenance there are surveillance algorithms of the status of the equipment, both regarding external connections and the internal operation of the equipment and of test functions to check the correct operation of the outputs and leds: Monitoring of the neutral toroidal transformer in open circuit. PTC sensor short circuit Self-diagnosis PBM-B base module leds and outputs test PBM-H module leds test This allows the installation motors to be started up in a staggered way, by means of an adjustable timer from 0 to 3600 s. The alarm and trip output relays are activated with positive safety. The following measurements are provided: Phase currents, neutral current (calculated as a digital sum of the phase currents), earth leakage current (measured by an external toroidal transformer), average phase current, negative sequence current, positive sequence current, thermal image and frequency. The algorithm used to measure the currents is the real RMS (real Root Mean Square real efficient value). 16 samples cycles sampling is performed. The sampling type is determined when the system frequency is adjusted. This is performed at a set time if the adjusted frequency is 50 or 60 Hz, and at variable time is it is adjusted at a variable frequency (45Hz to 65 Hz). The accuracy of the measurement is 2% over the whole range. The variable frequency sampling is only valid for models with alternating supply, as the alternating supply signal is taken as reference to calculate the line frequency. Up to four fault reports are stored in the non volatile memory. The fault reports contain information regarding the date, measurements and a subassembly of the status of the equipment which are sufficient to determine the cause of the incident (all the phase discriminated functions trips, the inputs and outputs). All the equipment information can be accessed from the PBM-H and from an RS485 communications port on terminals, which allows for the equipment to be included as part of a SCADA system. The RTU Modbus protocol is used. A communication session is established with a key that can be set by the user. The PBM-B is fitted with five signal leds and a reset button to reset the output and led latchs. The PBM-H module is equipped with an LCD with two rows and twenty columns and a six key membrane keyboard which can be used to access all the system information. It is also equipped with six adjustable signal leds. Each led can be assigned a 16 bit status OR and can be set as latched or not latched and/or as flashing or not flashing. It is also equipped with a start button and a stop button and a test/reset button which has the double function of testing the equipment leds (PBM-B and PBM-H) and resets the output and led interlocks. The PBM-B can operate normally without the PBM-H module. Once programmed, either by the mobile PBM-H or the communication, the PBM-B operates on its own, providing information via its leds or communication. Thanks to the available protection and monitoring functions, its easy to use HMI and its simple integration, the PBM provides a precise and practical solution for motor control central unit protection. The main features of the equipment are listed below, and these features will be explained in the rest of the manual. 20/128

25 4. PBM-B PROTECTION FUNCTIONS AND FEATURES 4.1. General settings The equipment's general adjustments are as follows: General settings Description Mínimum Maximum Step Unit Defect I B Rated motor current Model PBMB1* 0,8 6 0,01 A 0,8 Model PBMB5* ,01 A 4 Phase transformation ratio Frequency Hz/60Hz/var Hz 50 Motor start up threshold 1 8 0,01 xi B 1,5 Motor start up time s 60 Motor phases sequence - - ABC/ACB - ABC Time delayed equipment start up s 0 The first group adjustment is the motor rated current, which is referred to as I B in this manual. For model PBMB1*, the rated current range is 0.8 to 6 A. For model PBMB5*, the rated current range is 4 to 25 A. To protect the motor, the motor rated current (I B ), must be adjusted with the same value as the rated current that appears on the motor characteristics badge. In case to use a motor with nominal current below the minimum relay current setting value, pass through the hole of the relay n time. I B setting value will be I N xn, being I N nominal current shown on the motor plate. To protect a motor with nominal current greater than the maximum relay current setting value, current transformer will be used. I B setting value be nominal current shown on the motor plate divided by CTR which is phase transformation ratio. The motor start up threshold and "motor start up time" adjustments are used for the function which monitors the motor start up, to establish that the start up is excessively long. NOTE: It is necessary to select a value between 1 and 200 second for motor Start Up item in order to get a correct monitoring of the motor start. In case of wanting to deactivate this monitoring, it is possible to do it, under user responsibility, selecting 0 value. Nevertheless, it is recommende to maintain the monitoring of motor start activated to avoid unexpected damages in the motor. 25/128

26 The frequency can be adjusted to 50 HZ, 60 Hz and variable frequency (with the equipment maintaining measurement accuracy and time within the range of 45 Hz to 65 Hz). The variable frequency can only be applied to models with alternating supply voltage. The motor phase sequence adjustment is used for the reverse function to determine whether or not the wiring consistent with the adjustments. The time delayed equipment start up " adjustment is used for staggered installation motor start up Overload The overload function meets international standard IEC and IEC A physical model based mathematic model is used to simulate the motor's thermal condition. The mathematic model used combines two thermal images: A heating image and a cooling image. The heating image represents the thermal condition of the windings of the stator and rotor, and the cooling image represents the thermal condition of the casing. The fact that PBM-B is fitted with a heating and cooling thermal memory, it can define the margins at all times so that the motor operates in a safe mode. The thermal image is a measurement of the motor heating condition. Unlike the overcurrent relay, time is not counted as of when a fault is detected but rather this is continuously determining the thermal condition of the motor. The trip time depends on the trip class selected, the circulating current and the previous motor thermal condition. The thermal image is calculated based on the following equation: θ = 100 x (I/I t ) 2 x (1 e -t/ζ ) + θ 0 x e -t/ζ Where: I, maximum current of the three phases I t, trip threshold current ζ, thermal constant. θ 0, initial thermal condition The trip time comes from the equation: t = ζ x ln { [(I/I t ) 2 (θ 0 / 100) ] / [(I/I t ) 2-1] } The trip time accuracy is 5% above the theoretical time. The algorithm uses the maximum current of the three phase currents. If the maximum current is greater than 15% of the adjusted current I B, the heating thermal constant is applied. If the maximum current is less than 15% of the adjusted current I B, the cooling thermal constant is applied. The overload function trips when the thermal image reaches a value of 100%. This value is reached in the time when the circulating current is equal to the adjusted input in the thermal function (I t ). A thermal image adjustable level is established to generate an alarm. Should a trip occur, the overload function is reset when the thermal image drops below the set alarm level. 26/128

27 The thermal constant has the following values: ζ heating = 37 x trip class ζ cooling = 90 x trip class If there is independent mechanical ventilation, ζ cooling = (90 x trip class) / 4 This function settings are as follows: Overload Description Minimum Maximum Step Unit Defect Enable function - - Yes/No - Yes Tap 1 2 0,01 I B 1,15 Trip class - - 5,10,15,20,25,30,35,40,45-5 Independent mechanical ventilation - - Yes/No - No Alarm % 80 We allow the overload function tap adjustment in a range of between 1 and 2 times I B, so that the user can make the most of the motor capacity. However, it must be pointed out that standard IEC recommends the tap setting to be between 1.05 and 1.20 times I B. Trip classes 5, 10, 20, 30 and 40 are standard. The other class settings 15, 25, 35 and 45 permit adaptation to the various motor types Phase imbalance The imbalance function is applied on the three phase system made up of the three phase currents (IA, IB, IC). The average current of the three values is taken as reference. The function is operative if the average current is greater than 10% of the motor set current I B and becomes inoperative if the average current is less than 8%. A correct operation band is established based on the average current. Its upper and lower limits result from the % adjusted imbalance and 5% hysteresis is considered in resetting. 27/128

28 The imbalance resetting and activation limits are determined as follows, based on the % adjusted imbalance (value d1%): Upper limit activation I average * (100 + d1)% Upper limit resetting I average * (100 + d1 5)% Lower limit activation I average * (100 - d1)% Lower limit resetting I average * (100 - d1+ 5)% The criteria is applied to the three phases. If a phase current is greater than the upper limit or less than the lower limit the function start up is activated. Once the function has been activated, if the phase current drops below the upper reset limit or rises above the lower reset limit, the function is instantly reset. The function trip can be time delayed and two different times have been established: one applies when the motor is starting up, and the other when the motor is in operation. As a result, a possible phase failure can be detected in the motor start up and a fast trip can be executed. This function settings are as follows: Imbalance Description Minimum Maximum Step Unit Defect Enable function - - Yes/No - Si % Imbalance % 30 Motor start up time 0, ,001 s 0,6 Motor operation time 0, ,001 s 5 This function is similar to the phase failure function. In principle, this function must be used to detect small current imbalances. The use of the phase failure function is recommended to provide protection against large imbalances of the lower limit Phase failure The phase failure function is applied on the three phase system made up of the three phase currents (IA, IB, IC). The average current of the three values is taken as reference. The function is operative if the average current is greater than 10% of the adjusted current I B and becomes inoperative if the average current is less than 8%. Based on the average current, a lower limit is established resulting from the % adjusted imbalance and 5% resetting hysteresis. The phase failure resetting and activation limits are determined as follows, based on the % adjusted imbalance (value d2%): 28/128

29 Lower limit activation Iaverage* (100 d2)% Lower limit resetting Iaverage* (100 d2+ 5)% The criteria is applied to the three phases. If a phase current is less than the lower limit the function start up is activated. Once the function has been activated, if the phase current rises above the lower reset limit, the function is instantly reset. There is only on operating time, regardless of whether the motor is starting up or in operation. This function settings are as follows: Phase failure Description Minimum Maximum Step Unit Defect Enable function - - Yes/No - Yes % Imbalance % 30 Time 0, ,001 s Phase sequence The sequence function is activated when the phase sequence is detected to not be in accordance with the general phase sequence adjustment (ABC/ACB). The phase sequence function detection algorithm is based on the determination of the positive and negative sequence of the essential currents component. The function is operative if the positive sequence current or the negative sequence current is greater than 10% of the adjusted current I B and stops operating if the positive sequence current and the negative sequence current is less than 8%. This function settings are as follows: Phase sequence Description Minimum Maximum Step Unit Defect Enable function - - Yes/No - No Time 0,02 2 0,001 s 0, /128

30 4.6. PTC Function The PTC sensors provide accurate control of the temperature the motor is subjected to at various points of its structure. The sensor operation is based on an extremely fast increase in its resistance once its own temperature limit has been reached. PTC sensor protection is used in cases such as the following: Motors with high start up/stoppage frequencies Motor operating at speeds which are lower than the range it is designed for. When there is a restricted air supply. In intermittent operations and/or constant braking. High air temperatures. PTC sensor short circtui or open circuit and overtemperature are detected. Overtemperature activates the trip contact whilst sensor open circuit and short circuit activate the alarm contact. The PTC sensor protection thresholds cannot be set. They are predefined as follows: Activation resistance Reset resistance Overtemperature > 3600 Ω < 1800 Ω Short-circuit < 20 Ω > 30 Ω Open circuit > 4000 Ω < 3900 Ω The PTC function has the enable function adjustment: PTC Description Minimum Maximum Step Unit Defect Enable function - - Yes/No - No The trip time is 500 ms. The PTC sensors used shall have a maximum current of 1mA and a maximum voltage of 2.3 V. Maximum cold resistance Minimum cold resistance 1500 Ω 50 Ω 30/128

31 4.7. Jam function The motor is considered to be operating in jam conditions when the resistant torque of the motor is very close to the maximum torque the motor can provide, whereby motor rotation is slowing down. This function shall be disabled during motor start up. Following start up, the function shall be enabled whenever permitted by the user. This function settings are as follows: JAM Description Minimum Maximum Step Unit Defect Enable function - - Yes/No - No Tap 1 3,5 0,01 I B 2,5 Operating time 0, ,001 s 10 Operation time is independent of the operating current which flows through the equipment, whereby, should the phase current exceed the adjusted value during the preestablished time, the protection function is activated (trips). It is deactivated when the average phase current value falls below 95% of the adjusted tap Locked rotor This function detects a locked rotor. This function shall be disabled during motor start up. Following start up, the function shall be enabled whenever permitted by the user. This function settings are as follows: Locked rotor Description Minimum Maximum Step Unit Defect Enable function - - Yes/No - No Tap 3,5 6 0,01 I B 3,5 Operating time ,001 s 5 Operation time is independent of the operating current which flows through the equipment, whereby, should the phase current exceed the adjusted value during the preestablished time, the protection function is activated (trips). It is deactivated when the average phase current value falls below 95% of the adjusted tap. 31/128

This protection function can be set by using three parameters: Instantaneous neutral overcurrent Group Description Minimum Maximum Step Unit Defect I 0 >> Enable function - - Yes/No - No Tap 0,1 1 0,01 I B 0,1 Operating time 0,02 5 0,001 s 1 Operation time is independent of the operating current which flows through the equipment, whereby, should the neutral current (I0) exceed the adjusted value during the preestablished time, the protection function is activated (trips). It is deactivated when the average neutral current value falls below 95% of the adjusted tap Neutral inverse time overcurrent This protection function can be set by using five parameters: Neutral inverse time overcurrent Group Description Minimum Maximum Step Unit Defect I 0 > Enable function - - Yes/No - No Curve - - (1*) - Inverse Dial 0,05 1,25 0,01-1,25 Tap 0,1 1 0,01 I B 1,00 Operating time 0,02 5 0,001 s 0,2 (1*) Inverse, Very inverse, Extremely inverse, Defined time If the option "Defined time" is selected for the curve setting, the unit behaves like an instantaneous overcurrent unit. In this case, the unit operating time is adjusted by using the parameter "Operating time". If a curve (inverse, very inverse or extremely inverse) is selected for the curve setting, the operating time depends on the curve, dial and tap settings. If the unit operates as defined time, the function is activated at 100% of the set tap value, and it deactivates at 95%. If the unit operates with a curve, the function is activated at 110% of the set tap value, and it deactivates at 100%. 32/128

33 The reset is instantaneous in both cases. The activation time is accurate to ±5% or ±30ms, whichever is higher, of the theoretical activation time. The curves used are IEC , which are described in the "Curves" section Instantaneous earth leakage overcurrent. With external toroidal transformer. This protection function can be set by using three parameters: Instantaneous earth leakage overcurrent.

34 If the option "Defined time" is selected for the curve setting, the unit behaves like an instantaneous overcurrent unit. In this case, the unit operating time is adjusted by using the parameter "Operating time". If a curve (inverse, very inverse or extremely inverse) is selected for the curve setting, the operating time depends on the curve, dial and tap settings. If the unit operates as defined time, the function is activated at 100% of the set tap value, and it deactivates at 95%. If the unit operates with a curve, the function is activated at 110% of the set tap value, and it deactivates at 100%. The reset is instantaneous in both cases. The activation time is accurate to ±5% or ±30ms, whichever is higher, of the theoretical activation time. The curves used are IEC , which are described in the "Curves" section Undercurrent The undercurrent function is used to detect whether the motor operation current is less than the desired level, due to the operation of the motor in no load due to transmission breakage, transformer belt underload, no load pump, The undercurrent function is not enabled during motor start-up. This function settings are as follows: Undercurrent Group Description Minimum Maximum Step Unit Defect I < Enable function - - Yes/No - No Tap 0,3 1 0,01 I B 0,5 Operating time 0, ,001 s 1 Activation is at 100% of the adjusted value and resetting at 105%.

Motor start up monitoring The adjustments relating to motor start up monitoring are as follows, which as in the general settings group: Motor start up monitoring Description Minimum Maximum Step Unit Defect Motor start up threshold 1 8 0,01 I B 1,5 Motor start up time ,001 s 60 The following automaton describes the operation of this function: Iav erage < 8% IB tstart up ++ tstart up ++ Iav erage > 10% IB Iav erage < 8% IB Iaverage> Treshold Iaverage < 95% Treshold Motor Stand by Motor first step Motor second step Motor in operation t real start up > t real adjusted Iav erage < 8% IB Extended start up The motor is considered to be on standby when the average current is less than 8% of the adjusted current I B. When the average current is greater than 10% of the adjusted current we start monitoring start up and switch to Motor first step status. From Motor first step, when the average current is greater than the adjusted motor start up threshold, we switch to Motor second step". From Motor second step, when the average current is less than 95% of the adjusted start up threshold, we switch to Motor in operation". In Motor first step" and "Motor second step" we monitor the start up time. If the measured start up time is greater than the adjusted start up time, we switch to Extended start up. 35/128

36 Iav erage Treshold 95% Treshold 10% IB Stand by second step in operation first step t < Adjusted start up time There are two status bits in the miscellanous group, related to motor monitoring: Motor in operation and excessive start up time. The following statistics are related to motor start up: Number of start ups Maximum start up current: Maximum last start up current: Medium last start up current: Measured start up time (second step time) Number of operating hours (motor in operation) NOTE: To ensure proper working of undercurrent function (I<) it is absolutely necessary to adjust motor start up time to a value different to Overload curves The first graph shows the class 5, 10, 15, 20, 25, 30, 35, 40 and 45 trip curves starting from an initial thermal condition of 0% (cold). The following graphs show the class 5, 10, 15, 20, 25, 30, 35, 40 and 45 trip curves with initial thermal conditions of 0% (cold), 60% (hot 60%), 75% (hot 75%). The 60% hot thermal curves represents the trip time starting from an initial thermal condition of 60% which is reached with a thermal balance of I = 0.9 I B. The 75% hot thermal curves represents the trip time starting from an initial thermal condition of 75% which is reached with a thermal balance of I = I B.

50 5. MONITORING AND CONTROL 5.1. Measurements The three phase currents are provided (IA,IB,IC), as well as the neutral current (I0) calculated as a digital sum of the phase currents, the earth leakage current (IG) measured by mediums of an external toroidal transformer, the positive sequence current, the negative sequence current, the average current of the three phases, the thermal image measurement (%) and the line frequency. The earth current value is obtained in two ways: By mediums of an external toroidal transformer which covers the three phases (IG). Additionally, the PBM-B will check that the toroidal transformer is not in an open circuit. If the three phase motor is directly connected to earth of via a sufficiently low impedance, the earth current value can be obtained by adding the currents measured via the three transformers fitted on the PBM-B itself (I0). The currents measurement (IA,IB,IC,I0,IG) are R.M.S. values (real efficient value). The measurement accuracy is ±2% in the whole measurement range. 16 samples cycles sampling is performed. Sampling can be taken at line frequency (50 or 60Hz) or at a variable frequency, adjusting the equipment sampling to the real frequency. Using the sampling at a variable frequency, a measurement accuracy of ±2% is guaranteed in the 45HJz to 65 Hz range. The variable frequency sampling will be valid in the models which are supplied alternating voltage, as the supply voltage is taken as a reference to calculate the frequency. The frequency is measured using the zero cross algorithm. The supply voltage shall be taken as reference, whereby the frequency measurement shall be valid for models supplied with grid alternating voltage. Below are the residual neutral and phase measurement ranges of the PBM-B models: Model PBM1X PBM5X Range I B 0,8-6 A 4 25 A Residual neutral and phase measurement range with no external current transformers.

To exit the hmi test menu from any status, except the Key status, press the C key. To exit the hmi test menu from the Key status, hold the C key down. To obtain more detailed information, the method for navigating the menus is explained graphically in the LCD and keyboard section Power suppply The PBM.B equipment permits two different power supplies to be selected per model: Vac/dc 24/48 Vdc The equipment s maximum consumption is 5W. It generates 24 Vdc, which are available via RJ- 45 to supply the other modules. To protect the power supply against unstable power situations, the microproccessor of the equipment s power supply inhibits the possibility of successive and repetitive starts, being necessary to wait a minimum of 1 minute after each relay switch off, so that it may consider the following switch on as correct and stable powering Earth toroidal transformer monitoring The earth toroidal transformer connection is checked if the IG> function or the IG>> function, or both, are permitted. If it is detected that the transformer connection has opened during a period of 1 second, the "G toroidal transformer open" status bit is activated. This bit is reset instantly Time delayed equipment start An adjustable timer is fitted which delays output activation in the PBM power supply for the amount of time set in the Time delayed equipment start up parameter in the set of general settings. In this way all the installation's motors can be started up in a staggered way. The time delay can be adjusted within a range of 0 to 3600 seconds (1 hour). The "Miscellaneous" states group includes the Enable outputs " bit. During the equipment start up time delay this bit is at 0, thus preventing the physical outputs from being activated. Once the equipment start up time delay is complete, the bit switches to 1 and the physical outputs are enabled Equipment reset The three reset types considered on the PBM equipment are as follows: Automatic reset Time delayed automatic reset Manual reset 65/128

66 If automatic reset has been set, the equipment is reset when the trip condition has disappeared. If automatic time delayed reset has been set, the equipment is reset when the trip condition has disappeared and the set reset time has passed. If manual reset has been set, the equipment is reset when the reset order is received. This manual reset command can be recevied via three different routes: PBM-H, communication command or digital input. Each route may or may not be permitted by the settings Thermal image reset There are two thermal image reset commands. Reset of the thermal image to 75%, which can be accessed from the hmi and communication. Reset of the thermal image to 0%, which can be accessed from communication Reset/Test Button The Test/Reset button has two functions. A short press of the Test/Reset button tests the PBM-H and PBM-B leds simultaneously, with the following sequence: Lit for one second, off for one second, lit for one second and off permanently. Holding down the Test/Reset key (3 seconds) resets the leds and the latched outputs. This way, it is possible to restart the motor after a trip or after a manual stop generated by the user 66/128

74 7. COMMUNICATION AND HMI 7.1. RS485 Communication The PBM relay is fitted with an RS485 port for continuous communication with a remote computer or a SCADA system. The protocol that is used is Modbus RTU ( bit no parity 1 bit stop). The protocol map and documentation that are used are attached in an appendix to this manual. RS485 port output has two terminals (A and B). Up to 32 equipments can be connected to one bus; each equipment with a different modbus address. The equipment modbus address can be configured using the PBM-H. To minimise communication errors as a result of noise, the use of a stranded and shielded cable is recommended for the physical connection. All of the A terminals on one side, and all of the B terminals on the other must be connected together in order to make the connection. Resistors should be used at each end if very long cables are used. The best solution for avoiding reflection is to install resistors at both ends of the cable. The ohm value of these resistors must be equal to the cable impedance value. Fibre optics can be used in very aggressive environments, and they are connected by using the corresponding converters.

75 NOTE: The communication between PBM and HMI is Modbus and it uses this address 1, so all the relays are able to respond to this address.. This makes that, when there are more than one relay connected, the relay with this address 1 may have communication errors. Each relay must be configured with a different address and each one differet to 1. Reserve address 1 to the situation of local communication (only 1 relay) and use the rest of possibilities (from 2 to 255) to configure the relay s addresses Modbus RTU Protocol The protocol documentation and the modbus memory map are shown in the appendix to this manual LCD and keypad The module on the front is fitted with an alphanumeric liquid crystal (LCD) screen, measuring 2x20. This screen provides the user with access to read and write information about the settings parameters, measurements, states, fault reports. All of this information is arranged in a system of menus. A 6 key membrane keypad is fitted which can be used to access the information shown on the LCD screen and to navigate through the menu system. The and keys can be used to navigate through the different menus, the different options in each menu and the different values for the settings parameters. The OK key is used to access the menus and the different options, as well as to approve changes to values. The C key is used to delete and to go back through the menu levels. There is a Test/Reset key. Pressing this key once checks the correct operation of all the equipment leds (PBM-H leds and PBM-B leds). Holding this key down resets the outputs and leds latched. There are also I and O keys. Pressing the O key a trip occurs which results in the shutting down of the motor. By pressing the I key it is possible to control the commissioning of the motor but in order to do this the motor must be assigned an output contact (not available in the current model but it is available in the extension module) PBM-H LCD contrast Pressing the key increases the LCD contrast. Pressing the key reduces the LCD contrast. When the PBM-H is connected, the LCD contrast is reset to its default value. 75/128

76 7.3. PBCom communications programm The PBCom program, which works with the Windows 2000/XP and Windows 7 operating systems is provided, and can be used to gain access to all of the equipment information, to modify the settings and to save events using a graphic user interface. The following operations can be carried out using the SIcom program: Status reading Measurement reading Reading and changing settings Reading and deleting statistics Reading and downloading fault reports Changing the user passwords Loading settings files Date-time synchronisation Commands How to install PBCom Software To install the PBCom it is necessary the following link: The link will open the next screen, where key install must be pressed: The update of the software does not required any user s action, this is, if the computer is connected to Internet, PBCom updates itself when it is started User password The settings screen is restricted by means of a user password. The password consists of four digits. The equipment leaves the factory with the password "5555" which can later be changed by the user. From the PBM-H when a setting is to be modified, the equipment requests the user password and initiates a session if the password entered coincides with the equipment password. This session closes automatically if the keyboard is not used for five minutes. From the communication, in the settings confirmation sections, the user password field is added, and if this does not coincide with the equipment password the settings changes are rejected. 76/128

77 8. ACCESSORIES 8.1. Toroidal transformer The toroidal transformers measure the earth defect signal. To prevent sudden relay trips, a minimum leak current setting must be defined which depends on the diameter of the toroidal transformer. A fault current value of less than that specified in the following table is not recommended: Tyoe Ø CT Internal diameter (mm) Code Minimum tap (ma) CTD-1/ CT-1/ CT-1/ CT-1/ CT-1/ CT-1/ CT-1/ It is also recommended that the conductors be positioned as centrally as possible in the toroidal transformer to guarantee perfect differential relay operation. 77/128

82 8.6. PBM-B to PC connection cable To connect from the PBM-B to PC via RJ45 connector terminals without using RS485, you can use a cable with the following circuit diagram: Communication would remain as RS485 and would therefore require the use of a RS485-RS232 converter for connection to PC. 82/128

94 9. COMMISSIONING 9.1. Checklist for commissioning The commissioning sheets that are needed to record the commissioning process and the specific adjustments for each installed piece of equipment are found in the Appendix Inspection It is important to pay attention to the following aspects during the installation Visual inspection Make sure that the cabling has been installed as per the external connection diagrams Current transformers The high voltage that is generated in the secondary circuits of current transformers can cause death and could damage the facility. Therefore, the secondary circuits of current transformers should never be opened Commissioning It is recommended that the following safety measurements are taken before starting up the facility for the first time, or after a trip event: The "complete test" menu procedure should be applied. It is important to check that the measurements are correct once the facility has been powered up. Maintenance: FANOX recommends a minimum of one facility inspection per year, to at least go through the test menu and check the values of the measurements. 94/128

95 10. MODBUS RTU PROTOCOL This document describes the steps to follow to read and write data on the PBM, as per the ModBUS/RTU protocol. The memory map is described further on. The standard ModBUS/RTU protocol is used, so any program or PC can communicate easily with the equipment. The PBM-B always acts as a slave, which means that it never initiates communications. The master is always responsible for initiating communications. Only a subset of the ModBUS/RTU functions is implemented: Reading function 3. Writing function 16. The ModBUS/RTU protocol is independent from the hardware. Therefore, the physical layer can exist in different hardware configurations: RS232, RS385, fibre optic or Ethernet. Each byte of data is transmitted asynchronously and is made up of: 1 bit start, 8 data bits and 1 bit stop. The speed is bauds. The master must know the address of the slave that it is going to communicate with. No unit will act on requests from the master if the message is not addressed to them. The exception is when the 0 address, or broadcast address, is used, in which case the relay will act but will not send an answer of any type. Communications are made in packages or frames, which are groups of data that are sent asynchronously. The master transmits a frame to the slave, and the slave then replies with another frame (except in the case of broadcast messages). The end of the frame is marked by a dead time or silence time in the communication medium. The length of this time of silence varies depending on the transmission speed, as it is equivalent to 3 characters. The following table shows the generic package format that is valid for transmission and reception. However, each function has its own peculiarities, as will be described further on. 95/128

96 10.1. ModBus package format Customer address 1 byte Each device on a communications bus must have a unique address, as if this were not the case two units could reply to the same command at the same time. All the relay ports shall use this address which can be set at a value of between 1 and 247. When the master transmits a section with the slave address at 0 this indicates that it is a Broadcast. All the communications bus slaves shall perform the requested action, but none shall reply to the master. The Broadcast shall only be accepted for writing, as there is no sense in requesting Broadcast reading if no one will reply to this request. Function code 1 byte This is one of the function codes supported by the equipment. In this case, the only supported function codes shall be 3 for reading and 13 for writing. When the slave must reply with an exception to one of these sections, this is indicated by applying the largest bit of the corresponding function to 1. An exception for function 3 shall be indicated with 83 as a function code, and an exception for function 16 or 0x10 in hexadecimal, shall be indicated with 0x90. Data N bytes This consists of a variable number of bytes, depending of the function code. It can include: Addresses, data lengths, adjustments, exception codes or commands sent by the customer. CRC 2 bytes Two byte control code. ModBUS/RTU includes a 16 bit CRC in each section, for error detection. If the slave detects and erroneous section, based on an incorrect CRC, it shall not perform any actions, nor shall it reply to the master. The CRC layout is LSB- MSB. Dead time Time required to transmit 3.5 bytes A section is considered terminated when nothing is received on the line for a period of 3.5 bytes. i.e. 15 ms at 2400 bps 2 ms at bps etc Function codes HEX DEC CODE Modbus Name Definition Comments 0x03 3 Read Holding Registers Reading of any value This function allows the master to read 1 or more consecutive addresses of a relay.the records are always 16 bits, with the largest byte in first position.a maximum of 60 recordings can be read in a single package. 0x10 16 Preset Multiple Registers Writing This function allowsa one or more recordings to be written that represent one or more adjustments.the recordings have 2 byte length values, transmitted with the largest byte in first position.a maximum of 60 recordings can be written in a single package. 96/128

97 10.3. Error responses and exceptions The following error codes are defined by the ModBUS protocol: 01 ILLEGAL FUNCTION 02 ILLEGAL DATA ADDRESS 03 ILLEGAL DATA VALUE The slave does not support any functions with the function code received in this message.
