The function will be active only if there is voltage in the line feeding the motor, to avoid nuisance trips due to the lack of voltage. The 469 will consider the bus energized only if the measured voltage is greater than 20% of nominal voltage.
Page 37: Introduction
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 38 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 39: Ordering Information
256 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. Trip counters record the number of occurrences of each type of trip.

Page 47: Installation
Any 469 can be installed in any 469 case, except for custom manufactured units that are clearly identified as such on both case and unit, and are equipped with an index pin keying mechanism to prevent incorrect pairings.
Page 48: Product Identification
FIGURE 3–2: Seal on Drawout Unit 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 49: Installation
FIGURE 3–4: Single 469 Cutout Panel FIGURE 3–5: Double 469 Cutout Panel After the mounting hole in the panel has been prepared, slide the 469 case into the panel from the front. Applying firm pressure on the front to ensure the front bezel fits snugly against the front of the panel, bend out the pair of retaining tabs (to a horizontal position) from each side of the case as shown below.
Page 50: Unit Withdrawal And Insertion
Once the handle is released from the locking mechanism, the unit can freely slide out of the case when pulled by the handle. It may sometimes be necessary to adjust the handle position slightly to free the unit. FIGURE 3–9: Slide Unit out of Case GE Multilin 3–4 http://www.GEindustrial.com/multilin...
Page 51: Ethernet Connection
The unit does not require cleaning. CAUTION Ethernet Connection If using the 469 with the Ethernet 10Base-T option, ensure that the network cable is disconnected from the rear RJ45 connector before removing the unit from the case. This prevents any damage to the connector.

Page 56: Description
CT circuit is shorted by automatic 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. Ideally, the phase CT primary should be chosen such that the FLA is 100% of the phase CT primary or slightly less, never more.
Page 57 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.

Page 61: Voltage Inputs
B input and the 469 neutral terminal, must be installed for open delta VTs. Polarity of the VTs is critical for correct power measurement and voltage phase reversal operation.
Page 62: Digital Inputs
CAUTION 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.
Page 63: Analog Outputs
FIGURE 3–21: Loop Powered Transducer Connection Analog Outputs The 469 provides 4 analog output channels which may be ordered to provide a full- scale range of either 0 to 1 mA (into a maximum 10 kΩ impedance) or 4 to 20 mA (into a maximum 1200 Ω...
Page 64 ±36 V with respect to the 469 safety ground. b) Reduced RTD Lead Number Application The 469 requires three leads to be brought back from each RTD: Hot, Return and Compensation. This can be quite expensive. It is however possible to reduce the number of leads required to 3 for the first RTD and 1 for each successive RTD.
Page 65 There will be an error in temperature readings due to lead and connection resis- tances. 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 66: Output Relays
6 SERVICE relay is normally energized and de-energizes when called upon to operate. It also de-energizes when 469 control power is lost and will be in its operated state. All other relays, being non-failsafe, will normally be de-energized and energize when called upon to operate.
Page 67: Drawout Indicator
FIGURE 3–26: Alternate Wiring for Contactors 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 68: Dielectric Strength
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 supervision, and the safety ground terminal G12.

Page 123: Reduced Voltage
MESSAGE START TIMER: 200 s 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 124 NOTE 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.

Page 136 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 137: 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 138 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...
Page 139: Overload Curve Setup
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 140 S5 Thermal Model Motor Management Relay Table 5–1: 469 Standard Overload Curve Multipliers PICKUP STANDARD CURVE MULTIPLIERS (× FLA) × 1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 × 9 × 10 × 11 ×...

Page 142 The distinct parts of the thermal limit curves now become more critical. For these conditions, it is recommended that the 469 custom curve thermal model be used. The custom overload curve feature allows the user to program their own curve by entering trip times for 30 pre-determined current levels.

Page 149 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 150 Motor Management Relay 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.
Page 151 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.
Page 152 0.167, voltage unbalances of 1, 2, 3, 4, and 5% equal current unbalances of 6, 12, 18, 24, and 30% respectively. Based on this assumption, the GE Multilin curve illustrates the motor derating for different values of k entered for the setpoint.

Page 154 Motor Management Relay h) RTD Bias The 469 thermal replica operates as a complete and independent model. However, the thermal overload curves are based solely on measured current, assuming normal 40°C ambient and normal motor cooling. If the ambient temperature is unusually high, or motor cooling is blocked, the motor temperature will increase.
Page 155: S6 Current Elements
This allows the motor to start without nuisance tripping. The overreach filter removes the DC component from the asymmetrical current present at the moment of fault. This eliminates overreach; however, the response time slows slightly (10 to 15 ms) but remains within specification. GE Multilin 5–49 http://www.GEindustrial.com/multilin...

Range: 1 to 60 s in steps of 1 CURRENT UNBALANCE MESSAGE TRIP DELAY: 1 s For the 469 relay, unbalance is defined as the ratio of negative-sequence to positive-sequence current, I , if the motor is operating at a load (I ) greater than FLA.
Page 159: Ground Fault
Various situations (e.g. contactor bounce) may cause transient ground currents during motor starting that may exceed the Ground Fault pickup levels for a very short period of time. The Ground Fault time delays are adjustable in 10 ms GE Multilin 5–53 http://www.GEindustrial.com/multilin...
Page 160: Phase Differential
This momentary DC component will cause each of the phase CTs to react differently and the net current into the ground input of the 469 will not be negligible. A 20 ms block of the ground fault elements when the motor starts enables the 469 to ride through this momentary ground current signal.
Page 161: S7 Motor Starting Acceleration Timer
Some motor soft-starters allow current to ramp up slowly while others limit current to less than FLA throughout the start. Since the 469 is a generic motor relay, it cannot differentiate between a motor with a slow ramp up time and one that has completed a start and gone into overload.
