2.4.1Resetting Controller after a Fault Shutdown
Always identify and correct the cause of a fault shutdown before resetting the controller. Use the following procedure to reset the generator set controller after a fault shutdown.
1.Move the generator set master switch to OFF/RESET.
7.Move the generator set master switch to the AUTO position for startup by remote transfer switch or remote start/stop switch.
Note: The controller’s LED display remains off until an engine start command is received.
Opening and closing a remote start/stop contact also resets the controller.
2.5 Continuous Power Mode
2.Disconnect the generator set from the load using the line circuit breaker or ATS. See the safety precautions at the beginning of this section before proceeding.
3.Identify and correct the cause of the fault shutdown. See the safety precautions at the beginning of this section before proceeding. Refer to Section 4, Troubleshooting.
4.Start the generator set by moving the generator set master switch to RUN. Test operate the generator set to verify that the cause of the shutdown has been corrected.
5.Move the generator set master switch to OFF/RESET.
6.Reconnect the generator set to the load using the line circuit breaker or ATS.
The ADC 2100 is powered by the generator set engine starting battery. A jumper on the back of the controller maintains power to the controller at all times. Controllers are shipped with the jumper connected.
Note: The 8.5 and 12 RES generator sets are equipped with
Disconnecting the jumper allows the controller to power down automatically 48 hours after the generator set shuts down if the generator set master switch is in the AUTO position. A remote start signal (from a transfer switch or a remote start/stop switch connected to controller leads 3 and 4) or moving the generator set master switch to the RUN position turns the controller back on.
Contact an authorized distributor/dealer to disconnect the jumper, if necessary.
