  • Page 7: The Lm10 Relay

    1.1.1 The LM10 Relay The GE Multilin LM10 Motor Protection System is a modular device designed to protect motors from various fault conditions. This device interfaces with a DeviceNet network. The network will monitor and control the relay status and functions. The relay also has the capability of operating in a standalone mode.

  • Page 8: Overview

    The two control relays are labeled “RUN 1” and “RUN 2”. These relays are enabled on command from the control logic. If the LM10 detects a fault condition the relays will be de- energize, causing the motors to shut down.

  • Page 9: Power Supply

    1.2.4 Power Supply The LM10 Motor Protection System has an on-board power supply with a fuse that converts the AC input to the levels necessary to operate this device. The operating range is 96 to 140 V AC, nominal 120 V control power (80% to 117%). The supply has programmable auto-restart capability of up to 4 seconds.

  • Page 10: Features

    The main task of the programming and display unit (PDU) is to provide status information to a local user. The PDU can display the requested parameter(s) on the LCD in either English or Spanish. Additionally, the PDU can be used to configure the LM10 via the RS232 serial communications port.

    FIGURE 4–3: Trip Curve with Jam and Stall Enabled The LM10 will trip on a jam or stall condition if these faults are enabled (see Run 1 and Run 2 Setup on page 4–32). The overcurrent curve cannot be disabled. Therefore, if the jam or stall values are set greater than the time allowed by the standard trip curve, the LM10 will trip before a jam or stall condition can be reached.

    AuxSns1 AuxSns2 (auxiliary sense failure): Should the LM10 detect that a contactor did not open/close according to its command, an auxiliary sense (AuxSns) trip failure will be recorded in the fault record and shut down the run relay. This fault is factory preset at 0.4 seconds.
  • Page 41 No seal in contact is required. In the maintained mode a run switch must stay closed if opened the LM10 will stop the motor. The stop switch input for safety reasons will interrupt the run relay in maintained or momentary mode. If the run switch is on when the stop command is given, it will need to be turned off and back on to get the motor running again.
