  • Page 36: Installation

    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.

    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.

    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.

    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.
