2.5.6 Resetting the Controller after a
Fault Shutdown
Always identify and correct the cause of a fault
shutdown before resetting the controller.
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 or
remote start/stop switch.
Note: The controller's LED display remains off
until an engine start command is received.
Opening and closing the remote start/stop contact
also resets the controller.

2.6 Circuit Protection

If the generator set circuit breaker trips or the fuses blow
repeatedly, see Section 4, Troubleshooting, for possible
causes.
2.6.1

Line Circuit Breaker

A 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.
18 Section 2 Operation
2.6.2
The junction box contains three inline fuses.
Use the Figure 1-1 for locations. Always identify and correct the
cause of a blown fuse before restarting the generator
set. Refer to section 4, Troubleshooting, for conditions
that may indicate a blown fuse. Obtain service from an
authorized distributor/dealer.
Controller Fuse. A replaceable 10-amp fuse protects
the controller circuitry. If the controller display is dark,
check the battery and battery connections and then
check the controller fuse. Replace the fuse if it is blown.
Relay Fuse. A replaceable 10-amp fuse protects the
engine relays. If the generator set does not crank, check
the battery and battery connections and then check the
relay fuse. Replace the fuse if it is blown.
Auxiliary Winding Fuse. A replaceable 10-amp fuse
for 4 lead generator sets (20 amp fuse for 12 lead
generator sets) protects the alternator.
2.6.3
The junction box contains the fuse block.
Figure 1-1 for locations. Always identify and correct the
cause of a blown fuse before restarting the generator
set. Refer to section 4, Troubleshooting, for conditions
that may indicate a blown fuse. Obtain service from an
authorized distributor/dealer. See Figure 2-7.
