2.6.5 Resetting the 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 c ircuit 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.
Opening and closing the remote start/stop contact
also resets the controller.
2.6.6 Continuous Power Mode
The controller 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: Remote communications require an active
(powered-up) controller. Be advised that the
ADC consumes 250 mA when the master switch
is in the AUTO position with the jumper
connected. If you do not plan to use your
generator set for a long period of time, Kohler
recommends moving the master switch to the
OFF/RESET position (0 mA draw).
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 P21
connector, leads 3 and 4) or moving the generator set
master switch to the RUN position turns the controller
back on. See the Installation Manual for instructions to
disconnect the jumper.
2.7 Circuit Protection
If the generator set circuit breaker trips or the fuses blow
repeatedly, see Section 4, Troubleshooting, for possible
causes.
2.7.1 Line Circuit Breaker
A line circuit breaker interrupts the generator output in
the event of a fault in the wiring between the generator
and the load. The line circuit breaker location is shown
in Figure 1-1. If the circuit breaker trips, reduce the load
and switch the breaker back to the ON position.
