Page 9: Introduction
The 469 Motor Management Relay is a microprocessor based relay designed for the protection and manage- ment of medium and large horsepower motors and driven equipment. The 469 is equipped with six output relays for trips, alarms, and start blocks. Motor protection, fault diagnostics, power metering, and RTU func- tions are integrated into one economical drawout package.
Page 10 Ground faults or earth leakage as low as 0.25 A may be detected using the GE Power Management 50:0.025 Ground CT. CT inputs for phase differential protection are also provided. The 12 RTD inputs provided may be individually field programmed for different RTD types. Volt- age transformer inputs allow for numerous protection features based on voltage and power quantities.
Page 11 LAST TRIP DATA actual values. The 469 event recorder stores up to 40 time and date stamped events including the pre-trip data. Each time a trip occurs, the 469 stores a trace of 8 cycles pre-trip and 8 cycles post-trip for all measured AC quantities.
Page 12: Order Information
All 469 features are standard; there are no options. The phase CT secondaries, control power, and analog out- put range must be specified at the time of order. The 469 differential CT inputs are field programmable for CTs with 1 A or 5 A secondaries. There are two ground CT inputs, one for the GE Power Management 50:0.025 core balance CT and one for a ground CT with a 1 A or 5 A secondary, also field programmable.

Page 19: Installation
2 INSTALLATION 2.1 MECHANICAL 2.1.1 DESCRIPTION The 469 is packaged in the standard GE Power Management SR series arrangement, which consists of a dra- wout unit and a companion fixed case. The case provides mechanical protection to the unit and is used to make permanent connections to all external equipment.
Page 20: Product Identification
2.1.2 PRODUCT IDENTIFICATION Each 469 unit and case are equipped with a permanent label. This label is installed on the left side (when fac- ing the front of the relay) of both unit and case. The case label details which units can be installed.
Page 21 2.1.3 INSTALLATION The 469 case, alone or adjacent to another SR series unit, can be installed in the panel of a standard 19-inch rack (see the diagram below for panel cutout dimensions). Provision must be made when mounting for the front door to swing open without interference to, or from, adjacent equipment.

Page 27: Typical Wiring
2.2 ELECTRICAL 2.2.2 TYPICAL WIRING A broad range of 469 applications are available. Although it is not possible to present typical connections for all possible schemes, this section will cover the interconnections of instrument transformer inputs, other inputs, outputs, communications, and grounding. See Figure 2–9: TERMINAL LAYOUT on page 2–6 and Table 2–1: 469 TERMINAL LIST on page 2–7 for terminal arrangement.
Page 28: Phase Current Inputs
If the unit is withdrawn, each phase CT circuit is shorted by auto- matic mechanisms on the 469 case. The phase CTs should be chosen so the FLA is no less than 50% of the rated phase CT primary.
Page 29 2.2 ELECTRICAL The 469 measures up to 5 A secondary current if the 1 A / 5 A tap is used. Since the conversion range is rela- tively small, the 1 A or 5 A option is field programmable. Proper selection of this setpoint ensures proper read- ing of primary ground current.
Page 30: Differential Current Inputs
469 case if the unit is withdrawn. The maximum differential CT primary current is 5000 A. The 469 measures up to 5 A secondary current for the differential CT inputs. Since the conversion range is rel- atively small, the 1 A or 5 A option is field programmable. Proper selection of this setpoint ensures proper read- ing of primary phase differential current.
Page 31: Voltage Inputs
2.2 ELECTRICAL 2.2.7 VOLTAGE INPUTS The 469 has three channels for AC voltage inputs, each with an isolating transformer. There are no internal fuses or ground connections on the voltage inputs. The maximum VT ratio is 150.00:1. The two VT connec- tions are open delta (see Figure 2–10: TYPICAL WIRING DIAGRAM on page 2–8) or wye (see below).
Page 32: Analog Inputs
2.2.9 ANALOG INPUTS The 469 provides terminals for four 0 to 1mA, 0 to 20mA, or 4 to 20mA current input signals (field programma- ble). This current signal can be used to monitor external quantities such as vibration, pressure, or flow. The four inputs share one common return.
Page 33: Rtd Sensor Connections
DESCRIPTION The 469 monitors up to 12 RTD inputs for Stator, Bearing, Ambient, or Other temperature monitoring. The type of each RTD is field programmable as 100 Ω Platinum (DIN 43760), 100 Ω Nickel, 120 Ω Nickel, or 10 Ω Cop- per.
Page 34: Reduced Rtd Lead Number Application
1. There will be an error in temperature readings due to lead and connection resistances. This technique is NOT recommended for 10 Ω Copper RTDs. 2. If the RTD Return lead to the 469 or any of the jumpers break, all RTDs from the point of the break will read open.
Page 35: Two Wire Rtd Lead Compensation
GROUNDING OF RTDs Grounding of one lead of the RTDs is done at either the 469 or at the motor. Grounding should not be done in both places as it could cause a circulating current to flow. Only RTD Return leads may be grounded.
Page 36: Output Relays
This will provide failsafe operation of the motor; that is, the motor will be tripped off line in the event that the 469 is not protecting it. If however, the process is critical, annun- ciation of such a failure will allow the operator or the operation computer to either continue, or do a sequenced shutdown.
Page 37: Drawout Indicator
2.2.13 DRAWOUT INDICATOR The Drawout Indicator is simply a jumper from terminals E12 to F12. When the 469 is withdrawn from the case, terminals E12 and F12 are open. This may be useful for differentiating between loss of control power as indi- cated by the R6 SERVICE relay and withdrawal of the unit.
Page 38: Rs485 Communications Ports
The last device at each end of the daisy chain should be terminated with a 120 Ω ¼-watt resistor in series with a 1 nF capacitor across the ‘+’ and ‘–’ terminals.

Page 40: Dielectric Strength Testing
It may be required to test a complete motor starter for dielectric strength (“flash” or “hipot”) with the 469 installed. The 469 is rated for 2000 V DC isolation between relay contacts, CT inputs, VT inputs, trip coil super- vision, and the safety ground terminal G12. Some precautions are required to prevent damage to the 469 dur- ing these tests.

BLOCK START An 469 Block Start is a feature that prevents or inhibits the start of the motor based on some logic or algorithm. An 469 Block Start feature is always assigned to the Block Start relay. In addition to the Trip relay(s), a trip will always operate Block Start relay.
Page 48: Relay Assignment Practices
There are six output relays. Five of the relays are always non-failsafe, the other (Service) is failsafe and dedi- cated to enunciate internal 469 faults (these faults include Setpoint Corruption, failed hardware components, loss of control power, etc.). One of the output relays is dedicated as the Block Start relay; it is dedicated to fea- tures that are intended to block motor starting.

Page 52: Serial Ports
If the RS485 serial communication link is used, then all the relays can keep synchronized time. A new clock time is pre-loaded into the 469 memory via the RS485 port by a remote computer to each relay connected on the communications channel. After the computer broadcasts (address 0) a "set clock" command, all relays in the system begin timing at the same instant.
Page 53: Default Messages
Management Relay MESSAGE After a period of inactivity, the 469 displays default messages. Between 1 to 20 default messages can be selected. Multiple default messages automatically scan in sequence at a rate determined by S1 469 SETUP \PREFERENCES\DEFAULT MESSAGE CYCLE TIME. Any actual value can be selected for default display; in addition, up to five user programmable messages can be created and displayed (Message Scratchpad).

ESCAPE INFORMATION: No MESSAGE These commands clear various informative and historical data when the 469 is first applied on a new installa- tion. RESET MOTOR INFORMATION: Counters for number of motor starts and number of emergency restarts can be viewed in actual values. The 469 also learns various motor characteristics through motor operation. These learned parameters include acceleration time, starting current, and starting thermal capacity.
Page 57: S2 System Setup
As a safeguard, PHASE CT PRIMARY and MOTOR FULL LOAD AMPS are defaulted to "Not Programmed" when shipped from the factory. A block start indicates that the 469 was never programmed. Once PHASE CT PRIMARY and MOTOR FULL LOAD AMPS are entered, the alarm resets itself. The phase CT should be chosen so the FLA is no less than 50% of the rated phase CT primary.

The 469 may be used on variable frequency drives when the NOMINAL SYSTEM FREQUENCY is set to "Variable". All of the elements function in the same manner with the following exceptions: the ratio of negative to positive sequence current is calculated from 0 to 30%, not 40%, and the voltage and power elements will work properly if the voltage waveform is approximately sinusoidal.
Page 60: Reduced Voltage
START TIMER: 200 s MESSAGE The 469 can control the transition of a reduced voltage starter from reduced to full voltage. That transition may be based on "Current Only", "Current and Timer", or "Current or Timer" (whichever comes first). When the 469 mea- sures the transition of no motor current to some value of motor current, a 'Start' is assumed to be occurring (typically current will rise quickly to a value in excess of FLA, e.g.
Page 61 ‘b’ contacts from the reduced voltage contactor and the full voltage contactor. Once transition NOTE is initiated, the 469 assumes the motor is still running for at least 2 seconds. This prevents the 469 from recognizing an additional start if motor current goes to zero during an open transi- tion.

ALARM EVENTS: Off MESSAGE The primary protective function of the 469 is the thermal model. It consists of five key elements: the overload curve and overload pickup level, the unbalance biasing of the motor current while the motor is running, the motor cooling time constants, and the biasing of the thermal model based on Hot/Cold motor information and measured stator temperature.

Page 85 The 469 takes the information provided and create protection curves for any voltage between the minimum and 100%. For values above the voltage in question, the 469 extrapolates the safe stall protection curve to 110% voltage. This current level is calculated by taking the locked rotor current @ 100% voltage and multiply- ing by 1.10.
Page 86 The following two figures illustrate the resultant overload protection curves for 80% and 100% line voltage, respectively. For voltages in between, the 469 will shift the acceleration curve linearly and constantly based on measured line voltage during a motor start.

The 469 measures the ratio of negative to positive-sequence current. The thermal model may be biased to reflect the additional heating that is caused by negative sequence current when the motor is running. This bias- ing is accomplished by creating an equivalent motor heating current rather than simply using average current ).

A 20 ms block of the ground fault elements when the motor starts enables the 469 to ride through this momentary ground current signal.

The running differential delay can then be fine tuned to an application such that it responds very fast to sensitive (low) differential current levels. 4-52 469 Motor Management Relay GE Power Management...
Page 99: S7 Motor Starting
Some motor softstarters may allow current to ramp up slowly while others may limit current to less than FLA throughout the start. Since the 469 is a generic relay for protection of all motors, it cannot differentiate between a motor that has a slow ramp up time and one that has completed a start and NOTE gone into an overload condition.

If the STARTER FAILURE ALARM is set to "Latched" or "Unlatched", then the Starter Status input and motor current are monitored when the 469 initiates a trip. If the starter status contacts do not change state or motor current does not drop to zero after the programmed time delay, an alarm occurs. The time delay should be slightly longer than the breaker or contactor operating time.

6.1.3 DATA FRAME FORMAT AND DATA RATE One data frame of an asynchronous transmission to or from an 469 is default to 1 start bit, 8 data bits, and 1 stop bit. This produces a 10 bit data frame. This is important for transmission through modems at high bit rates (11-bit data frames are not supported by Hayes modems at bit rates of greater than 300 bps).
Page 170: Data Packet Format
If an 469 Modbus slave device receives a transmission in which an error is indicated by the CRC-16 calcu- lation, the slave device will not respond to the transmission. A CRC-16 error indicates than one or more bytes of the transmission were received incorrectly and thus the entire transmission should be ignored in order to avoid the 469 performing any incorrect operation.
Page 171: Algorithm
(i.e. all slaves start listening for a new transmission from the master). Thus at 9600 baud a delay of greater than 3.5 × 1 / 9600 × 10 = 3.65 ms will cause the communication link to be reset. GE Power Management 469 Motor Management Relay...

Actual Value ("input registers"). Holding and input registers are 16 bit (two byte) values transmitted high order byte first. Thus all 469 Setpoints and Actual Values are sent as two bytes. The maximum number of registers that can be read in one transmission is 125. Function codes 03 and 04 are configured to read set- points or actual values interchangeably because some PLCs do not support both function codes.

Modbus allows up to a maximum of 60 holding registers to be stored. The 469 response to this function code is to echo the slave address, function code, starting address, the number of Setpoints stored, and the CRC.
Page 182: Function Code 16: Performing Commands
16. To perform this operation using function code 16 (10H), a certain sequence of commands must be written at the same time to the 469. The sequence consists of: command function register, command operation register and command data (if required). The command function register must be written with the value of 5 indicating an execute operation is requested.
Page 183: Error Responses
6.3.1 DESCRIPTION When an 469 detects an error other than a CRC error, a response will be sent to the master. The MSbit of the FUNCTION CODE byte will be set to 1 (i.e. the function code sent from the slave will be equal to the function code sent from the master plus 128).
Page 184: Memory Map
6.4.1 MEMORY MAP INFORMATION The data stored in the 469 is grouped as Setpoints and Actual Values. Setpoints can be read and written by a master computer. Actual Values are read only. All Setpoints and Actual Values are stored as two-byte values.
Page 185: Event Recorder
6.4.4 WAVEFORM CAPTURE The 469 stores a number of cycles of A/D samples each time a trip occurs in a trace buffer, determined by the setpoint in S1 Preferences, Trace Memory Buffers. The Trace Memory Trigger is set up in S1 Preferences and this determines how many pre-trip and post-trip cycles are stored.
