Page 47: Overview
The 469 Motor Management Relay is a microprocessor based relay designed for the protection and management of medium and large horsepower motors and driven equipment. The 469 is equipped with six (6) output relays for trips, alarms, and start blocks. Motor protection, fault diagnostics, power metering, and RTU functions are integrated into one economical drawout package.
Page 48 A second overload curve is provided for two-speed motors. Ground faults or earth leakage as low as 0.25 A may be detected using the GE Multilin 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.
Page 49 Fault diagnostics are provided through pretrip data, event record, trace memory, and statistics. Prior to issuing a trip, the 469 takes a snapshot of the measured parameters and stores them with the cause of the trip. This pre-trip data may be viewed using the...
Page 50 CT inputs are field programmable for CTs with 1 A or 5 A secondaries. There are two ground CT inputs, one for the GE Multilin 50:0.025 core balance CT and one for a ground CT with a 1 A or 5 A secondary, also field programmable. The VT inputs will accommodate VTs in either a delta or wye configuration.

Page 63: Mechanical Installation
3.1.1 Description The 469 is packaged in the standard GE Multilin SR-series arrangement, which consists of a drawout 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. The only electrical components mounted in the case are those required to connect the unit to the external wiring.
Page 64 3.1.2 Product Identification Each 469 unit and case are equipped with a permanent label. This label is installed on the left side (when facing the front of the relay) of both unit and case. The case label details which units can be installed.
Page 65 3.1.3 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 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.

The ground CT circuits are shorted by automatic mechanisms on the 469 case if the unit is withdrawn. The 1 A / 5 A tap is used either for zero-sequence / core balance applications or residual ground connections where the summation of the three phase current CTs is passed through the ground current input (see the figure below).
Page 76 FIGURE 3–14: Residual Ground CT Connection The 469 measures up to 5 A secondary current if the 1 A / 5 A tap is used. Since the conversion range is relatively small, the 1 A or 5 A option is field programmable. Proper selection of this settings ensures proper reading of primary ground current.

469 relay and the long digital input cable. This will help prevent the relay falsely sensing the digital input as "closed" due to induced voltage on the cables as a result of the capacitive effect.
Page 81: Analog Input
3.2.7 Analog Inputs The 469 provides terminals for four 0 to 1mA, 0 to 20mA, or 4 to 20mA current input signals (field programmable). This current signal can be used to monitor external quantities such as vibration, pressure, or flow. The four inputs share one common return. Polarity of these inputs must be observed for proper operation The analog input circuitry is isolated as a group with the analog output circuitry and the RTD circuitry.
Page 82 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 Copper. RTDs must be three wire type. Every two RTDs shares a common return.
Page 83 There will be an error in temperature readings due to lead and connection resistances. This technique is NOT recommended for 10 Ω Copper RTDs. 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 84: Output Relay
RTD Grounding 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. Only RTD Return leads may be grounded.
Page 85 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, annunciation of such a failure will allow the operator or the operation computer to either continue, or do a sequenced shutdown.
Page 86: D Rawout I Ndicator
FIGURE 3–26: Alternate Wiring for Contactors 3.2.11 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 indicated by the 6 SERVICE relay and withdrawal of the unit.
Page 87: D Ielectric S Trength
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 1.9 kV AC for 1 second, or 1.6 kV AC for 1 minute (per UL 508) isolation between relay contacts, CT inputs, VT inputs, trip coil supervision, and the safety ground terminal G12.

Page 163 MESSAGE START TIMER: 200 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 measures 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 164 Auxiliary ‘b’ contacts from the reduced voltage contactor and the full voltage contactor. Once transition 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 transition.

Starter Auxiliary B STARTER This input is necessary for all motors. The 469 determines that a motor has stopped when the phase current falls below the level that the relay can measure (5% of CT primary).

Page 178: S5 Thermal Model
The motor manufacturer should provide a safe stall time or thermal limit curves for any motor they sell. To program the 469 for maximum protection, it is necessary to ask for these items when the motor is out for bid. These thermal limits are intended to be used as guidelines and their definition is not always precise.

Page 180: Thermal Model
MESSAGE ALARM EVENTS: Off 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 181 The 469 overload curve can take one of three formats: Standard, Custom Curve, or Voltage Dependent. Regardless of the selected curve style, thermal memory is retained in the register.
Page 182 If the motor starting times are well within the safe stall times, it is recommended that the 469 Standard Overload Curve be used. The standard overload curves are a series of 15 curves with a common curve shape based on typical motor thermal limit curves (see the figure and table below).

Page 194 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 at 100% voltage and multiplying by 1.10.
Page 195 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 thermal model adapts for these conditions if the settings HOT/COLD SAFE STALL RATIO is programmed. This settings value dictates the level of thermal capacity used the relay will settle at for current levels below the .

By convention, an induction motor consumes Watts and vars. This condition is displayed on the 469 as +Watts and +vars. A synchronous motor can consume Watts and vars or consume Watts and generate vars. These conditions are displayed on the 469 as +Watts, +vars, and +Watts, –vars respectively (see the figure below).
