Features:
- Handles two separate current-sensor feedback channels at the LS2100 load bridge.
- Separates sensor supply, current inputs, and the control-side signal connection.
- Provides dedicated terminal positions for ground and both CT polarities.
DS200FCSAG1A is assigned to the FCSA-L position, where load-bridge current measurements are organized before they continue into the static-starter control.
Independent LEM1 and LEM2 paths let a single missing current signal be compared against a working channel without immediately treating the entire feedback board as failed.
The three-position LEMPS plug establishes the sensor-supply rails, while CSPL carries the separate control connection and the TB bank preserves field-conductor polarity.
The General Electric DS200FCSAG1A Current Feedback Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Verifying the independent current-sensor supply
- Positive rail: Pin 1 of the DS200FCSAG1A LEMPS plug is identified as P15.
- Reference: Pin 2 is ACOM and provides the documented common point.
- Negative rail: Pin 3 is N15, completing the three-wire sensor-power connection.
- Measurement sequence: Disconnect LEMPS only with the equipment isolated, verify the three points, and reconnect the plug before operation.
Using the paired LEM channels to narrow a fault
- First channel: LEM1 receives one load-current sensor path on DS200FCSAG1A.
- Second channel: LEM2 provides a separate input for the other load-current measurement.
- Single loss: One absent reading directs inspection toward its LEM input and corresponding CT pair.
- Dual loss: When both readings disappear together, compare the shared supply and control interfaces before changing both sensors.
Keeping the CT conductors on their assigned terminals
- Ground point: TB1 is the designated ground terminal on the FCSA-L board.
- CT1 pair: TB2 carries CT1P and TB3 carries CT1N.
- Second loop: Current transformer channel two uses positive terminal TB4, with its negative conductor assigned to TB5.
- Polarity check: Label both positive and negative conductors before removal so the two feedback channels are not reversed during reconnection.
Confirming the load-bridge board position
- Functional location: DS200FCSAG1A occupies the FCSA-L position assigned to the load bridge.
- Orientation: The manufacturer drawing shows the board rotated 90 degrees in the cabinet assembly.
- Control connector: CSPL is the separate 12-position interface rather than the three-position sensor-supply plug.
- Fit check: Board position, orientation, terminal bank, and both connector types should agree before power is restored.
