4.9 ECM Interface Block Diagram and Connectors
The Generator Remote Interface provides power conditioning to the ECM PCB, and
connection between cabinet sensors and the APU control. The interface supplies all
necessary signals, alarms, logic power, and analog voltages required for telemetry at the
central office or relevant monitoring station, and allows the ECM to start and stop the engine
alternator as part of the network controlled periodic test sequence.
