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.

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.
