2.3.5 Resetting 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 the
OFF/RESET position.
2. Disconnect the generator set from the load using
the line circuit breaker or ATS. See the safety
precautions at the beginning of this manual before
proceeding.
3. Identify and correct the cause of the fault
shutdown. See the safety precautions at the
beginning of this manual 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. Shut the generator off by moving the generator set
master switch to the OFF/RESET position.
6. Reconnect the generator set to the load using the
line circuit breaker or ATS.
7. Move the generator set master switch to the AUTO
position for startup by remote transfer switch,
remote start/stop switch, or remote digital gauge.
Note: Opening and closing the remote start/stop
contact also resets the controller. Always identify
and correct the cause of the fault shutdown
before restarting the generator set.
2.3.6 Controller Power Down
The ADC 2100 is powered by the generator set engine
starting battery.
When the generator set master switch is in the AUTO
position, the controller automatically powers down 48
hours after the generator set stops if not configured for
CANbus communication with a remote gauge. A remote
start signal (from a transfer switch or a remote start/stop
switch connected to P21 connector, leads 3 and 4) or
moving the generator set master switch to the RUN
position turns the controller back on.
If the ADC 2100 is configured for CANbus
communication (e.g. for the remote digital gauge, see
the Installation Manual for controller configuration
information), the controller will not power down when in
AUTO. Remote communications require an active
(powered-up) controller.
Note: The ADC 2100 draws 250 mA when the master
switch is in the AUTO position and the unit is
configured for CANbus communication.
Exercise the generator set regularly as
recommended in Section 2.2 and use a battery
charger to maintain the engine starting battery.
