3 M60 UR Motor Management Relay Protection The M60 is a digital motor management relay designed for the protection of medium and large induction motors. The M60, part of the Universal Relay Family, offers advanced protection which includes: Motor Thermal Model This consists of six key elements: Overload curves Unbalance biasing Hot/cold motor compensation Motor cooling time constants biasing Start inhibit Emergency restart Overload Curves The M60 overload curve can take one of two formats: standard or Flexcurve. For all curve styles the algorithm retains thermal memory in a thermal capacity register. The user can create a custom curve, or use manufacturer s curves. The M60 standard overload curves consist of a curve shape with a multiplier value of one to 600. Unbalance Bias Unbalanced phase currents can cause rotor heating which is not shown in the motor thermal damage curve. Negative sequence current, which is generated by unbalanced phase currents, has a frequency that is approximately two times the line frequency.

A two part curve is constructed using three points: RTD bias minimum: if the minimum stator RTD is below this point no biasing occurs (typically 40 C) RTD bias maximum: if the maximum stator RTD temperature is above this setpoint the thermal memory is fully biased and thermal capacity is forced to 00% used (this is typically at the stator insulation rating) RTD bias center point: the center point temperature and thermal capacity used values are the rated running temperature and value determined by the hot/cold safe stall ratio respectively For values between the RTD bias maximum and minimum, the present thermal capacity used created by the overload curve is compared to the RTD bias thermal capacity. If the RTD bias thermal capacity used value is higher, it is used from that point forward. RTD bias curve. RTD Bias Maximum RTD Bias Center 0 RTD Bias Minimum Point Maximum Stator RTD Temperature ( C) A3M60.cdr Motor Cooling Time Constants The thermal capacity used value is reduced exponentially when the motor current is below the overload pickup setpoint. This reduction simulates motor cooling. The motor cooling time constants are programmed for both the stopped and running cases. The thermal model will track motor heating and cooling cycles accurately and always provide optimum protection.

4 M60 UR Motor Management Relay Emergency Restart This function resets the present Thermal Capacity Used to 0% to facilitate an immediate emergency Hot start that would otherwise be subject to a cooling time. An overload trip will still occur when the Thermal Capacity Used reaches 00%. Stator Differential When used on the stator windings of rotating machinery, this element automatically compensates for a mismatch up to a factor of ten between current transformer ratios. External fault restraint is provided by a dual slope percent differential approach with a smooth transition between the two slope regions. Overcurrent Protection IOC functions are available for phase, ground and neutral currents. TOC function is available for the ground current. A variety of standard time curves are provided plus two userprogrammable curves. Sensitive Directional Power This two-stage function is suitable for sensitive reverse and low-forward power detection. The element measures threephase power and accepts delta and wye connected VTs.

7 469 SR Motor Management Relay Protection The 469 is a motor management relay designed to protect and manage medium and large motors and driven equipment. The 469 offers extensive protection features such as: Motor Thermal Model The primary protective function of the 469 is the thermal model with four key elements: Overload curves Unbalance biasing Hot/cold motor compensation Motor cooling time constants Overload Curves The curve can take one of three formats: standard, custom, or voltage dependent. For all curve styles the 469 retains thermal memory in a thermal capacity Functional Block Diagram used register which is updated every 0. second. The overload pickup determines where the running overload curve begins. The 469 standard overload curves are a standard shape with a multiplier value of one to 5. The 469 also allows the user to create their own custom curve for special applications. The thermal limit curve must be provided by the motor vendor when starting high inertia loads because the motor acceleration time can actually exceed the safe stall time. The voltage dependent overload curve feature protects motors by monitoring voltage. During motor starting and acceleration, the thermal limit curve is adjusted accordingly. An acceleration curve is created for both minimum line voltage and 00% line voltage. TIME TO TRIP IN SECONDS The line voltage is monitored and the acceleration protection curve is adjusted between the minimum and maximum line voltage. Changes in impedance are reflected by motor terminal voltage and line current Typical custom overload curve.

8 469 SR Motor Management Relay Unbalance (Negative Sequence Current) Bias Negative sequence current, which causes rotor heating, is not accounted for in the thermal limit curves supplied by the motor manufacturer. The 469 measures unbalance as the ratio of negative to positive sequence current. The thermal model is biased to reflect the additional heating. Motor derating due to current unbalance can be selected via the setpoint unbalance bias k factor. RTD Bias curve. RTD Thermal Capacity Used (%) RTD Bias Minimum RTD Bias Maximum RTD Bias Center Point Maximum Stator RTD Temperature ( C) A4.cdr Additional Features Torque metering and protection, pulsed outputs, analog input differential for dual motor drives and cyclic load averaging for reciprocating motors have all been added to the 469 features. Special Features Upon request the 469 can also be programmed with the following modifications: undervoltage autorestart and an experimental broken rotor bar detection system. Medium motor derating factor due to unbalanced voltage. Note that the k=8 curve is almost identical to the NEMA derating curve k= k= k= k=8 0.5 k= PERCENT VOLTAGE UNBALANCE derafacta2.ai DERATING FACTOR Hot/Cold Motor Compensation The 469 has a unique feature for protecting the motor based on the hot/cold thermal damage information provided by the motor manufacturer. A two-part curve is constructed using three points: RTD bias minimum: if the minimum stator RTD is below this point no biasing occurs (typically 40 C) RTD bias maximum: if the maximum stator RTD temperature is above this setpoint the thermal memory is fully biased and thermal capacity is forced to 00% used (this is typically at the stator insulation rating) RTD bias center point: the center point temperature and thermal capacity used values are the rated running temperature and value determined by the hot/cold safe stall ratio respectively For values between the RTD bias maximum and minimum, the present thermal capacity used (created by the overload curve) is compared to the RTD bias thermal capacity. If the RTD bias thermal capacity used value is higher, it is used from that point forward. Motor Cooling Time Constants The 469 thermal capacity used value is reduced exponentially when the motor current is below the overload pickup setpoint. This reduction simulates motor cooling. The motor cooling time constants are programmed for both the stopped and running cases as a stopped motor will normally cool slower than a running motor. Since actual motor cooling is exponential the thermal model will track motor heating and cooling cycles accurately and always provide optimum protection. Exponential cooldown (hot/cold curve ratio 60%). 00 Thermal Capacity Used % FLA 50% FLA Time in Minutes 80680A3.cdr Protection and Control The 469 contains a full range of selectively enabled, self contained protection and control elements as detailed in the Applicability of 469 Features table. The 469 also has the ability to learn motor acceleration time, starting current and thermal capacity. Inputs and Outputs Current and Voltage Inputs The 469 has three-phase CT inputs for phase differential protection, and a ground CT for sensitive detection of ground faults or earth leakage. Voltage transformer inputs allow for numerous protection features based on voltage and power quantities. RTD Inputs The 469 has 2 field programmable RTDs that are normally used for temperature monitoring. The 469 circuitry compensates for lead resistance for leads of equal length. Digital Inputs The 469 has five pre-defined and four assignable digital inputs which can be configured to any one of 4 different functions or turned off. Analog Inputs The 469 has four analog inputs that can be used to monitor any external quantity. Output Relays Four output relays are assigned to trip, alarm, start block and service. Two auxiliary relays may be programmed for extra functions, in addition to a forced output relay feature. 49

9 469 SR Motor Management Relay Analog Outputs If analog outputs are connected to a PLC, real time process control is possible based on any of the four parameters that the 469 measures. If the motor is about to trip on overload or hot rotor stator for example, the PLC could reduce the load, preventing any downtime. Monitoring and Metering The 469 provides impressive monitoring and metering functions in one compact unit: Metering The 469 provides accurate metering of: A V W var VA PF Hz Wh varh, torque Demand: A W var VA peak Temperature (RTDs) Speed (if tachometer function is assigned to one of the digital inputs) Analog inputs Event Recording The event recorder stores motor and system information with a date and time stamp each time an event occurs up to 40 events. Oscillography The 469 records up to 64 cycles with 2 samples per cycle of waveform data for 0 waveforms (I a, I b, I c, I g, Diff a, Diff b, Diff c, V a, V b, V c ) each time a trip occurs. The record is date and time stamped.

10 469 SR Motor Management Relay User Interfaces Keypad and Display The 469 has a keypad and 40 character display for local control and programming without a computer. Up to 20 user-selected default messages can be displayed when inactive. In the event of a trip, alarm, or start block, the display will automatically default to the pertinent message and the Message LED indicator will flash. LED Indicators The 469 has 22 LED indicators on the front panel. These give a quick indication of 469 status, motor status, and output relay status. Communications The 469 is equipped with three communications ports. A front panel RS232 port allows easy local computer access. Two rear RS485 ports provide remote communications or connection to a DCS, SCADA, or PLC. The three ports support ModBus RTU protocol. The RS232 baud rate is fixed at 9600, while the RS485 ports are variable from 300 to 9,200 bps. All communications ports may be active simultaneously. Software The relay comes with the Windows -based 469PC software which can be used to manipulate and display 469 data. A simple point and click interface allows setpoint files for each motor to be stored, printed for verification, and downloaded to the 469 for error-free setpoint entry. The entire 469 manual is included as a help file for quick local access. URPC Program The Windows -based URPC program allows the creation of single line diagrams for substation and system monitoring schemes. Annunciator panel viewing, metering, and simple settings changes can also be performed using the program. The URPC program allows the user to access multiple 469s or different devices for metering in real time. The program may be used locally through the RS232 serial port or remotely through the other ports on the device.

15 369 Motor Management Relay Protection The 369 is a digital relay that provides protection and monitoring for three-phase motors and their associated mechanical systems. The 369 offers optimum protection including: Fifteen standard overload curves. 0,000,000 using FlexCurve. This curve can be used to protect motors with different rotor damage and stator damage curves, thus allowing total motor design capacity with complete protection. Typical FlexCurve TM HP, 3800 Volt INDUCED DRAFT FAN Start and Running The motor is protected under both acceleration and running conditions. An alarm or trip can occur based on the acceleration time, the number of starts per hour, the time between starts, or motor over-load conditions. Overload Curves One of fifteen standard overload curves may be programmed based on motor manufacturer specifications. Alternatively the user may program in a custom curve using the built-in FlexCurve function. The motor s service factor value is entered as the overload pickup level.

16 369 Motor Management Relay Undercurrent (Minimum Load) The undercurrent function is used to detect a decrease in motor current caused by a decrease in motor load. This is especially useful for indication of such conditions as loss of suction for pumps, loss of airflow for fans, or a broken belt for conveyors. A separate undercurrent alarm level may be set to provide early warning. Ground Overcurrent For ground overcurrent protection, all three of the motor conductors must pass through a separate ground CT. CTs may be selected to detect either high-impedance zero sequence ground or residual ground currents. The ground fault trip can be instantaneous or time delayed by up to 255 seconds. A low level of ground fault pickup is desirable to protect as much of the stator winding as possible. A 50:0.025 A CT, A or 5 A CT may be used for ground fault detection. Rapid Trip/Mechanical Jam Quick motor shut down can reduce damage to gears, bearings, and other mechanical parts associated with the drive combination. A current surge will cause the relay assigned to the rapid trip/mechanical jam function to become active. The user may set the pickup level, trip time delay and an alarm for early warning. Stator Overtemperature (Option R) Optional stator winding overtemperature protection can monitor up to 2 optional stator RTDs. If less than 2 RTDs are used for stator monitoring, the remaining RTDs may be used for any other temperature monitoring function desired. Temperature Monitor (Option R) Twelve optional RTD inputs are available. Any RTD inputs not used for stator RTD protection can be used for other temperature monitoring functions. Separate alarm and trip level temperatures can be selected for each RTD. Alternatively, a remote RRTD module can also be used with the 369 for temperature monitoring. Back-Spin Detection (Option B) The BSD option is used to detect flow reversal of a pump motor when check valves are not functioning or are non-existent. Once the pump has stopped rotating, the BSD will allow the pump to safely restart, minimizing downtime and preventing motor damage. The BSD uses sensitive circuits to detect the voltage produced by the back-spinning motor. Digital signal processing techniques determine the direction of rotation and predict the pump stop time. An underpower element trips the motor in case of loss of fluid to the pump (which also cools the motor). The metering option (M) is included in the BSD (B) option. Thermal Modeling The thermal model calculates the motor I 2 t value, based on actual motor load current, in terms of thermal capacity used. RTD Hot Motor Compensation (Option R) Optional hot motor compensation allows the RTDs measuring the stator temperature to act as a thermal capacity check by confirming the value calculated by the thermal model. The thermal capacity used is updated to reflect the higher of the two values. This accounts for both heat due to I 2 t and motor heating due to loss of cooling or extreme ambient temperatures. Additionally, the 369 allows the user to match the motor thermal characteristics with a dual slope RTD bias curve. The two part curve allows for easy integration of hot and cold motor damage curves to the RTD bias feature. RTD bias curve sample.

VALUE Monitoring and Metering The 369 offers a choice of optional monitoring and metering functions including: Metering (Option M) The 369 metering option provides monitoring of quantities such as PF, kw, frequency, etc. Several protection functions can be performed based on these parameters, including: Voltage Watts ( kw, MW ) Vars ( kvar, MVar) Power factor Frequency MWh Analog Outputs (Option M) Three optional isolated analog outputs are provided (in addition to the one analog output available in the base model) that can be field selected as 0 to, 0 to 20 or 4 to 20 ma outputs.

This information helps facilitate troubleshooting. An event record of the last 250 trips helps identify persistent problems. 5

17 369 Motor Management Relay Alarm functions include immediate overload warning, unbalance, undercurrent, and internal selfcheck fault. An alarm can allow corrective action to be taken before a trip occurs. Testing A simulation mode enables simulated currents to be used without the need for a relay test set. This is ideal for verification of settings and training. The simulation mode can be run from the front panel display or a PC. Software The relay comes with the Windows -based 369PC software to help manipulate and display 369 data. A simple interface allows setpoint files to be created, stored and downloaded to the 369 for error free setpoint entry. The 369PC program can also be used to generate graphical trend reports. Maximize production throughput and improve preventative maintenance with trend analysis. communications and control. Setpoints can be manipulated using the keypad and display. To help prevent tampering, a setpoint access input must be shorted before changes can be made. The display module can be separated from the relay and mounted remotely. Self explanatory messages make programming and monitoring easy. PHASE CT PRIMARY: 586 A LEARNED ACCELERATION TIME = 0.05 LED Indicators Ten LED indicators on the front panel provide quick visual indication of status. User Interfaces A variety of communication interfaces are available in the 369: Communications A front RS232 port is provided for downloading setpoints and interrogating the relay using the Windows -based 369PC program. Three independent rear RS485 ports offer the customer flexibility and performance for their communication network. The 369 can communicate at baud rates up to 9,200 bps using the industry standard ModBus RTU protocol. Both fiber optic (option F) and profibus interface (option P) ports are also available. Future Expansion An open architecture protocol and hardware interface allow different GE Multilin relays or devices by other manufacturers to be mixed on the same communication link. The 369 can be integrated into a plant control system, or operate alone. Internal flash memory allows easy upgrades by simply loading new program code via the front serial port. Read the trip record and pretrip values for quick fault diagnosis. URPC Program The Windows -based URPC program allows the user to create single line diagrams for substation and system monitoring schemes. Additionally, annunciator panel viewing, metering, and simple changes can also be performed using the program. With the URPC program the user can access multiple 369s or different devices for metering in real time. The URPC program may be run on a PC with the Windows 95/98/NT operating systems. The program may be used locally through the RS232 serial port or remotely through the other ports on the device. Display and Keypad The 40 character display and keypad provide convenient local Digital Inputs The 369 has six dry contact inputs. Setpoint access: these terminals must be shorted together in order to locally store new setpoints Emergency restart: momentarily shorting these terminals together when the motor is stopped will cause the thermal memory to discharge to 0% used, allowing for an immediate restart after an overload trip; this may compromise the thermal protection functions of the 369, making it possible for the motor to be damaged Reset: this input can be used for remote or automatic reset Speed switch: this connection allows the 369 to utilize an external speed device for locked rotor protection Differential relay: an external differential relay can be connected so that a contact closure on this input will cause an immediate differential trip Spare input: this can be set to provide an alarm or trip after a programmable time delay when a contact closure is sensed on these terminals All digital inputs other than setpoint access are fully programmable as general switch inputs. 58

25 MPM Motor Protection Meter DESCRIPTION The MPM provides additional metering capabilities such as three phase voltage, pf, real power, reactive power, Wh, and frequency for the GE Power Management 269 or 269 Plus Motor Management Relay. All setpoint programming for the MPM is accomplished via the 269 over the serial communications link. Due to the compact size of the MPM, it is especially practical for applications where mounting space is limited. The MPM is a black box unit which uses serial communications to transmit / receive data to and from the 269. Therefore, it can be mounted inside the switchgear or in a location where there is more room available. A single twisted pair communication wire is routed to the 269. To obtain optimum accuracy metering class CTs should be employed. But in applications where mounting space and/or cost is an issue, the relaying class CTs used with the 269 can be connected in series with the MPM. The MPM comes complete with four isolated 4-20 ma (A20 option) or 0- ma (A option) analog outputs which are permanently configured to provide an output based average current, real power (kw), reactive power (kvar), and power factor respectively. The MPM also comes complete with a powered form-c failsafe output relay. This relay can be used to indicate if the MPM is on or off. The relay will also change state if a self diagnostic failure is detected on the MPM.

29 0 SPM Synchronous Motor Protection and Control Protection The SPM controls starting, synchronizing and protection of collector-ring or brushless-type synchronous motors. Stall Protection An important protection function is preventing cage winding overheating during both starting and running out of synchronization conditions. For brushless motors, stall/acceleration protection is derived from the stator current inputs. Stall protection activates when an operating motor is stopped with power factor protection enabled. Protection characteristics are shown in the following graph. Typical cage heating protection for brushless motors. Trip Time (seconds) A B C Stall Time - 30 Sec Locked Rotor - 6XFLC Stall Time - 0 Sec Locked Rotor - 6XFLC Stall Time - 2 Sec Locked Rotor - 6XFLC Trip Current (Multiples of Programmed Full Load Current) 062A6.cdr A B C For collector ring motors, speed is determined from the frequency of the induced field current. At less than synchronous speed the following typical cage heating protection characteristics are used: Typical cage heating protection characteristics for collector ring motors.

DC Field Current Loss Protection This feature trips the motor when field current drops below the programmed setpoint after the motor has synchronized. To utilize this feature a separate accessory package must be ordered. Reduced Voltage Starting The SPM can temporarily extend the stall time during a reduced voltage start. This allows motor acceleration to synchronous speed in a longer time period than with a full voltage start. Incomplete Sequence Protection If the motor does not synchronize within the programmed time setpoint, the relay will trip the motor. 2 26F SPM 06A9.cdr ANSI DEVICE NUMBERS 26F Field overtemperature Undervoltage Undercurrent or underpower Incomplete sequence Instantaneous overcurrent Power factor Field application Lock out Tripping Reluctance torque sync. / resync.

This is used on equipment with exciters energized prior to motor startup. in time delay to prevent inadvertent tripping on transients. Two modes of pull-out protection are available, re-sync mode and ride-thru mode. These modes will be initiated if the lagging power factor drops below the programmed set point, or if a line current surge occurs which is above four times the motor full load current. Re-sync mode operation will cause the Field Application Relay (FAR) to remove the motor field excitation. The motor will continue to run with the field removed for the programmed power factor delay time. If re-synchronization does not occur within this time the trip relay will operate and the motor will stop. In ride-thru mode the motor field excitation is not removed immediately. Instead, the SPM allows the motor to run for the power factor delay time. If the power factor dip or line current surge persists the trip relay will operate and the motor will stop. Power Factor Regulation Power factor regulation is a DC control signal output used to control a variable SCR exciter output. This replaces the standard power factor analog signal output. This option is not recommended for brushless applications. The regulator has five set-points that can be adjusted while the motor is running to facilitate regulator tune-up. They are: PF setpoint range from 0.9 lagging, through.0 to 0.0 leading Reg output upper limit of the control voltage output signal Reg gain adjusted for optimum regulator performance Reg stability time adjustment to help compensate for instability Reg floor lower limit of the control voltage output signal Power factor regulation functional block diagram. A B C Main Contactor Field DC Supply to Motor Field Field Contactor Field Winding Overtemperature This function emulates a resistance temperature device (RTD) on the field windings. An RTD device s resistance is temperature dependent. As the temperature increases, the resistance of the RTD increases. To utilize this feature a separate PG2SPM or PG4SPM accessory must be ordered. Control Features The SPM offers users advanced control features such as: Power Factor (Pull-Out) Protection The SPM provides pull-out protection for synchronous motors operating in either generating or motoring modes. The SPM provides power factor settings and also displays the measured leading/lagging power factor. The power factor regulation option enables field forcing in advance of a pull-out condition. Motor pull-out protection is provided by a circuit which monitors the power factor and has a built Starting and Synchronizing For collector ring motors, the SPM detects the proper rotor speed and angle and determines the correct time to close the field application relay based on the percent synchronous slip setpoint. This applies excitation to the motor field and opens up the field discharge resistor loop. For brushless motors, the voltage is applied to the exciter after a preset programmable time elapses. Power factor pullout protection is then enabled. A contact (FCX) is also provided to signal automatic motor loading. Reluctance Torque Synchronizing When a lightly loaded synchronous motor pulls into synchronization before the rotor poles are externally magnetized, this is known as reluctance torque synchronizing. The SPM s field application control responds by properly applying excitation if a motor synchronizes on reluctance torque.

Self-Tests and Diagnostics The SPM has built-in test diagnostics to indicate that the relay is operating properly prior to start-up. The SPM's separate test mode allows the user to verify the following: Trip relay contacts System test Squirrel cage protection test Synchronization Power factor test Upon entering the test mode the SPM de-energizes the trip contact and upon exiting the test mode the trip contact is re-energized. System test performs a complete check on internal memory, input-output devices and other system functions. Inputs and Outputs The SPM offers the user a variety of input and output solutions: Field Voltage Input: The induced field voltages VF+ and VF- are monitored through their connection to the external discharge resistor via the VDN, providing instantaneous value of motor slip. Exciter Voltage Input: VE+ and VE- terminals are connected to the exciter via the VDN to monitor DC exciter voltage. Exciter Current Input: The field current IE+ and IE- terminals are connected to the DC field via a DCCT and a calibration module (ordered separately) to detect field loss. Motor Line Current: Two input terminals, plus two for brushless, are connected to the system current transformers. Motor 'On' Input: Accepts a normally closed dry electrical interlock that opens when the motor is energized and closes when the motor is de-energized. Reduced Voltage Starting Input: Accepts a normally open dry electrical interlock that closes when the motor reaches full voltage during a reduced inrush start. Control Power: The SPM has an AC power supply with a range from 85 to 265 VAC. If control voltage excursions occur outside this range, an external stabilizing transformer should be used in conjunction with optional separate power factor reference voltage inputs. Power Factor Reference Voltage: PF reference voltage derives from control power, V and V2. The SPM also has optional inputs for separately powered PF reference voltage, VEXT and V2EXT. Effective range 85 to 265 VAC. Power Factor Analog Signal Output: A zero to ten volts DC signal corresponds to motor power factor. Zero volts represents zero lagging power factor, five volts represents unity power factor, and ten volts represents zero leading power factor. A one volt change corresponds to an 8 degree phase shift. If power factor regulation is provided, this analog signal output is replaced with the PF regulation output. Power Factor Control Signal: This option uses the PF analog output to supply a 0 to 0 V control signal to a variable SCR exciter. Trip Relay: Two trip terminals are connected to a failsafe normally open contact. This contact closes on relay power up and opens on a trip condition to de-energize the motor. FAR Relay: Two field application relay terminal points are a normally open contact. This contact closes to apply DC to the PERSONAL COMPUTER GEPM RS485 CONVERTER OR EQUIVALENT 20 Ohm Inf TERMINATING TERMINATING RESISTOR CAPACITOR COM PORT RS232 DB9 GND A3 + A2 motor field to pull motor into synchronization. FCX Relay: The FCX (field contactor auxiliary) relay picks up a setpoint time delay after the FAR relay picks up and is used to signal external systems to auto load/unload the motor. Communications The SPM is equipped with a rear RS485 port that could be used for remote communications, or for connection to a DCS, SCADA, or PLC. The port supports ModBus RTU protocol. The RS485 port is variable from 300-5,000 bps. The communication port may be active simultaneously without adversely affecting response time. Software The Windows -based SPMPC software allows the user to manipulate and display SPM data on a PC. A simple point and click interface allows setpoint files for each motor to be stored, printed for verification, and downloaded to the SPM for error free setpoint entry. In addition, the complete SPM manual is included as a help file for quick local access. RS485 connection for a reliable communication system that is immune to system transients.

37 239 Motor Protection Relay TRIP TIME (sec) Protection The 239 is a digital motor protection relay designed for threephase AC motors and associated mechanical equipment. Advanced protection features include: Motor Starting During acceleration, the motor is protected by an I 2 t overcurrent curve which passes through the setpoints Locked Rotor Current and cold Safe Stall Time. The running overload curve is not active during acceleration, therefore providing starting protection independent of running protection. Separate start and run modeling provides optimum rotor and stator protection. SEPARATE START AND RUN PROTECTION SAFE STALL TIME x FLC RUN CURVE LOCKED ROTOR CURRENT CURRENT START CURVE 8969A5.CDR Motor Running To protect the motor while it is running, one of 5 different curves can be selected to accurately match the motor overload characteristic. Curves automatically adjust for hot motor compensation to ensure correct thermal modeling. A user-programmable overload lockout time allows sufficient cooling after an overload trip. An Auto Reset feature resets the overload trip once the thermal capacity has decreased to 5% or less. An immediate overload alarm alerts the operator. This may be useful for systems that do not normally experience overloads. An immediate overload pickup setpoint is also available. Trip time overload curves, data and formulae are provided for protection and co-ordination. TRIP TIME (seconds) 0,000, CURVE PHASE CURRENT (multiples of full load) 8965A8.CDR Overheating To detect the effects of motor overheating due to such things as blocked ventilation or high ambient temperature, direct temperature sensing is necessary. Temperature rise under these types of conditions is usually slow enough to allow the accurate sensing of the actual motor temperature. A motor temperature input for a thermistor is standard on the 239. Additionally, three RTDs located in the stator and/or bearings can be connected to the 239 with the RTD temperature sensing option. This provides displayed temperatures as well as alarm and trip settings for both bearing and stator RTDs. The RTD temperature sensing option gives more precise protection from overheating. BEARING RTD 239 OVERLOAD CURVES Full Load Setpoint STATOR THERMISTOR OR RTDs BEARING RTD 8968AK.CDR Locked Rotor A mechanical jam pickup and time delay can help prevent damage to a locked rotor during running. Thermal Capacity A thermal capacity used alarm is triggered when the user s setpoint has been exceeded. Single-Phase (Unbalance) The unbalance protection function has an unbalance pickup level and time delay that can trigger a trip or an alarm. Ground Fault Aging and thermal cycling can cause the stator insulation to break down, resulting in ground faults. Ground faults can also occur in motors because of environmental conditions such as moisture or conductive dust. The 239 can trigger a trip or an alarm if the ground pickup level is exceeded. A time delay may be entered for time coordination of systems with several levels of ground fault detection. Phase Short Circuit Complete protection from phaseto-phase and phase-to-ground faults is provided. This function can trip or activate an auxiliary relay either instantaneously or delayed by up to 60 seconds. Undercurrent This function is typically used to protect pumps from loss of suction, fans from loss of airflow due to a closed damper, or conveyor systems from a broken belt. This function can be used as an alarm or as a trip, or disabled if not required. Alternatively this feature can be used as a preoverload warning by setting the undercurrent pickup above the normal operating current but below the rated full load current. 84

38 239 Motor Protection Relay Monitoring and Metering The 239 provides users with advanced monitoring and metering functions that include: Metering Measured values include: Phase current Ground current Unbalance Current % of full load (how close to overload) Motor thermal capacity used (how close to trip) Stator temperature (RTD option) Bearing temperature (RTD option) Multi-Speed Motors Optional switches allow alternate parameters to be activated for protection of multi-speed motors. This allows for additional setpoint groups for: Phase CT primary Full load current Overload curve Short circuit trip settings Analog Output Option The analog output option provides an isolated 0 to, 0 to 20, or 4 to 20 ma signal for interface to a PLC. The single output that is continuously monitored can be THERMAL CAPACITY selected as: average USED % phase current, motor full load %, 92546A3.cdr thermal capacity used, or RTD temperature. For local operator monitoring, a thermal capacity meter can be used with this output. Information such as process loading and proximity to tripping or overheating can be obtained with this output. Fault Diagnosis The cause of a trip along with measured values of current, unbalance and temperature at the time of trip are displayed. This information facilitates troubleshooting. A trip record of the last five causes of trip helps identify a persistent problem. Alarm functions include immediate overload warning, unbalance, undercurrent and internal self check fault. Often an alarm can be generated soon enough to enable corrective action to be taken before a trip occurs. Testing While periodic calibration is not required, the PICKUP LED is useful during commissioning or routine verification to indicate the pickup point for phase overload or ground. A simulation mode is also available that enables simulated currents to be used without the need for a relay test set. This is ideal for verification of settings and training.

39 TRIP ALARM AUXILIARY SERVICE PICKUP COMMUNICATE 239 Motor Protection Relay The simulation mode can be run from the front panel display or a PC. User Interfaces The 239 offers a variety of user interfaces: Communications The 239 features an RS485 connection with ModBus RTU protocol to communicate with most types of PLCs and computers. This allows any monitored value, status and setpoints to be remotely accessed by a PLC or SCADA system. Correct operation of the communication port is verified by a front panel LED. Future Expansion GE Multilin relays communicate using an open architecture protocol and hardware interface, allowing different relays or other devices to be mixed on the same communication link. Due to its standard communication platform, the 239 can operate alone or be integrated into a plant control system. With a standard platform, product upgrades are easily installed in the non-volatile flash memory by simply loading new program code via the serial port. Product update from GE Multilin on CD. Transfer new product enhancements to existing 239 relays via the serial port. Software For quick and accurate entry of all relay setpoints, the Windows - based 239PC software can be used instead of the front panel keypad and display. A PC can connect to the 239 via the serial port and a RS232/RS485 convertor (available as an accessory). All setpoints are stored in a file and can be printed easily. When new relays are added, a complete file of settings can be downloaded for error-free setpoint entry. Enter setpoints directly to the 239 or copy/save relay settings to a file. All information that can be accessed from the relay can also be displayed on a PC. This includes actual values, setpoints, status and trip records. View motor current, temperature, statistics and status. Install the latest product enhancements in existing relays via the serial port. 239 Motor Protection Relay CAUSE OF LAST TRIP: MECHANICAL JAM URPC Program COMING SOON The URPC program allows the creation of single line diagrams for substation and system monitoring schemes. Additionally, annunciator panel viewing, metering, and simple device settings changes can also be performed using the program. With the URPC program the user can access multiple 239s or different devices for metering in real time. The Windows -based URPC program may be used remotely through ports on the device. Display and Keypad The 40 character LCD and keypad provide convenient local communications and control. Setpoints can be modified locally using the keypad and display. To help prevent unauthorized setpoint changes, a setpoint access input must be shorted before changes can be made. LED Indicators Six LED indicators on the front panel provide quick visual indication of status. Switch Inputs The 239 has three fixed and two user defined switch inputs: Setpoint access: these terminals must be shorted together for keypad setpoint configuration Emergency restart: momentarily shorting these terminals together when the motor is stopped will reset the thermal capacity used to 0%, allowing for an immediate restart after an overload trip. This will compromise the thermal protection functions of the 239, making it possible to damage the motor External reset: this input allows remote or automatic reset Option switch and 2: these inputs can be monitored by the serial port for process signalling; they can also be programmed to provide an alarm or trip after a programmable time delay 896A8.CDR 86

45 MM2 Intelligent MCC Controller Protection and Control The MM2 is available with a variety of advanced protection and control features depending on the model ordered. This is outlined in the Model Table on page 98. Overload An overload trip occurs when the thermal capacity value equals 00%. Thermal capacity used is calculated from accumulated I 2 t value and chosen overload curves. True RMS current sensing ensures correct response to the heating effect of harmonics. One of 2 different I 2 t time overcurrent overload curves may be selected from eight standard curves and four NEMA compatible curves. Of the 2 overload curves available, four are NEMA compatible time/current overload curves Locked/Stalled Rotor To help prevent damage to mechanical equipment such as pumps or fans, the MM2 will trip when the running current exceeds the stalled rotor trip level after the programmed time delay. This feature may be set to OFF if desired, and it is disabled during the inrush of motor starting. Ground Fault The ground fault level is measured as a percentage of the CT primary. Ground overcurrent can be detected either from the residual connection of the phase CTs or from the zero sequence CT. A delay time is set to prevent false alarms from momentary surges. Both a ground fault alarm and trip are provided. The alarm can be set below the trip level to provide an early warning of insulation breakdown. Overtemperature An input from motor winding thermistors is available. The MM2 can accept both positive temperature coefficient (PTC) and negative temperature coefficient (NTC) sensors. A thermistor level can be selected for both alarm and trip. Cooling Time After an overload trip, the thermal capacity value decreases exponentially to model the motor cooling characteristic. An overload trip can be reset when the thermal capacity value decreases to 5%. A stopped motor cooling time can be set to determine how long it takes for a stopped motor to reach steady state ambient temperature from its maximum allowable temperature. Undercurrent/Underpower Both undercurrent and underpower alarms and trips are provided with time delays. Protection against failed shearpin or loss of pump flow, which may result in only a small change in current, is provided by the underpower alarm. Contactor Failure The MM2 monitors the contactor while performing start and stop commands. If the contactor does TIME IN SECONDS Phase Unbalance The MM2 monitors the percentage unbalance in the motor phase currents. If a phase current unbalance of greater than 5% exists for more than five seconds an alarm is generated. If a phase current unbalance of greater than 30% exists for more than five seconds a trip occurs. 92 CURVE # CLASS 30 CLASS 20 CLASS 5 CLASS MULTIPLE OF PICKUP CURRENT (PER UNIT) 80903D4.cdr Functional Block Diagram 480 VOLT BUS FUSE CONTACTOR PHASE PT PHASE CT GROUND CT THERMISTOR 52 WINDING THERMISTOR LOAD G 49 CONTACTOR A (FORWARD/WYE) CONTACTOR B (REVERSE/DELTA) 3 46 MANAGER 2 AUX RELAY AUX 2 RELAY CONTROL INPUTS 4-20mA INPUT RS485 REMOTE COMMUNICATION 200-9K2 BAUD DEVICE PROTECTION Standard Protection 49/5 overload 46 phase unbalance (single-phase) welded/open contactor Option 2 Enhancement 50G/5G ground fault 48 locked rotor/stalled rotor 49 hot winding (thermistor) 3 undercurrent/underpower 2 undervoltage 59 overvoltage PROCESS PLC OR TRANSDUCER 8062B9.dwg

Additional Alarms The MM2 has programmable alarms to warn of a number of abnormal conditions. These include: acceleration time exceeded, abnormal inverter starter, incomplete start, motor greasing, contactor inspection, motor stop time, analog input, and process interlock switch open. Starters The MM2 can control a variety of starter types using the contactor outputs. Contactor A is used for full voltage, non-reversing starters. Contactor A and B are used for reversing, two-speed, autotransformer, inverter, wye-delta open transition, slip ring, and part winding starters. Contactors A, B, and one auxiliary output are used for the reduced voltage wye-delta closed transition starter. Undervoltage Auto Restart MM2 can initiate timers to restart selected drives upon the return of supply voltage. If control voltage is restored within the programmed restart time, the motor will be restarted immediately. If the control voltage takes longer to be restored, the MM2 can be programmed to attempt a restart after a programmed time delay. Outputs The MM2 has one or two contactors (A and B). There are also two auxiliary programmable output relays available on the MM2, which can be assigned to any one of 3 functions. Switched Inputs The MM2 has up to six fixed control inputs. These are used for start A and B, stop, local isolator, and contactor A and B status. The MM2 also has up to 0 programmable switch inputs. Each input can have one of 33 interlock functions assigned to it. A function can be assigned to one interlock input only. Monitoring and Metering The MM2 offers advanced monitoring and metering which includes: Metering The MM2 meters and displays: RMS current of each phase Ground fault leakage current Motor load as a % of full load current Thermal capacity used (%) according to I 2 t history and chosen overload curve; hot/cold ratio is used to model heating when running below full motor current % unbalance Power (kw) Energy (kwh) Voltage Analog input Trip Record When the MM2 issues a trip command a record is generated which includes the cause and pre-trip actual values. The motor can be automatically restarted after a momentary power loss when this feature is enabled. When the control voltage drops below the dropout voltage the contactors are de-energized. The Analog Input The analog input can be scaled to user defined values. High and low alarm and trip setpoints are recorded with time delays. Statistics and Maintenance The MM2 records statistical data about relay and motor operation, allowing the user to set the interval at which routine maintenance Cost Effective MCC Wiring with MM2. One MM2 is typically mounted in each starter of a motor control center.

47 MM2 Intelligent MCC Controller tasks should be performed. When the times are exceeded an alarm is generated. These include: Motor greasing interval: number of hours between bearing lubrication Contactor inspection: number of starts after which contactor contacts must be inspected for wear Maximum motor stopped time: the maximum number of hours the motor can be left shut down User Interfaces The user can communicate with the MM2 through a variety of interfaces: Display and Control Keys The panel mount model has a large user STOP key which stops the motor. When both options are ordered with the MM2, the panel mount model may be ordered with a two-line 40 character display and additional control keys. The display and keypad can be used for local programming, showing information on alarms and trips, and displaying monitoring and metering values. Indicator LEDs The panel mount MM2 has nine status LEDs. The display model has two additional LEDs which indicate auto mode or manual control mode. Communications The MM2 uses a ModBus RTU RS485 connection for communication. Up to 32 MM2s can be daisy-chained together on a single communication channel. The MM2 supports operation at 200 to 9,200 bps. A RS232/485 converter module may be used to connect a personal computer to the MM2. Software The MM2 is provided with a Windows -based communications program called MM2PC. It allows access to all the features of the MM2 with easy to use, pull-down menus. Using this program it is possible to: Program or modify setpoints Load or save setpoints from or to a disk Read actual values from the MM2 Monitor status Read pre-trip data and trip record Display dynamic trending of actual values Get help on any topic Print the instruction manual from disk URPC Program The URPC program allows the user to create single line diagrams for substation and system monitoring schemes. Additionally, annunciator panel viewing, metering, and simple settings changes can also be performed using the program. With the URPC program the user can access multiple MM2s or different devices for metering in real time. Models Mounting Configurations The MM2 can be ordered in either chassis mount or panel mount with display. The chassis mount model is the black box version of the MM2. It is mounted inside the motor control center (MCC). The chassis mount and panel mount without display models come with all the standard features and may be ordered with one or both of the option packages. Setpoints are loaded through the RS485 port.
