Test Shutdown(s) Procedure

The installer will test the system to verify that diagnostic
messages are correctly shown on the system control panel
digital display, as follows:
FC_1 - Low Battery
No test procedure required for this fault.
FC_2 - Low Oil Pressure
Locate wire #85 (A) connected to the oil pressure switch.
Connect an installer-supplied jumper wire to wire #85.
With the system switch in AUTO position, push and hold
MANUAL OVER-RIDE to start the generator. With the
generator running, connect other end of jumper to a good
ground location such as the engine block. The generator will
shut down and FC_2 will be displayed on the system control
panel. Remove the jumper wire. Turn the system switch to
OFF for 30 seconds to clear the fault.
FC_3 - Low Voltage
With the system switch in AUTO position, push and hold
MANUAL OVER-RIDE to start the generator. With the
generator running at no load, turn the generator circuit
breaker to OFF. The generator should shut down and
FC_3 will be displayed on the system control panel. Turn the
system switch to OFF for 30 seconds to clear the fault. Turn
the circuit breaker to ON position.
FC_4 - Engine Fails to Start
With the generator not running, turn the installer supplied
manual fuel valve to the OFF position. With the system
switch in AUTO, turn off utility power. The engine will crank,
attempting to start. After approximately a two-minute start
attempt (10 seconds of crank, 10 seconds of rest) the
generator should terminate the start attempt and FC_4 will
be displayed on the system control panel. Turn the system
switch to OFF for 30 seconds to clear the fault. Turn the
installer supplied fuel valve to the ON position.

FC_5 - Low Frequency
No test procedure required for this fault.
FC_6 - Engine Overspeed
No test procedure required for this fault.
FC_7 - High Temperature
Locate wire #95 (B) connected to the temperature switch.
Connect an installer-supplied jumper wire to wire #95.
With the system switch in AUTO position, push and hold
MANUAL OVER-RIDE to start the generator. With the
generator running, connect other end of jumper to a good
ground location such as the engine block. The generator
should shut down and display FC_7 on the system control
panel. Remove the jumper wire. Turn the system switch to
OFF for 30 seconds to clear the fault.
FC_8 - Transfer Switch Fault
(Units with ACCM II or later transfer switch only)
Verify that utility power is present at the automatic transfer
switch. With the system switch in AUTO position, carefully
remove one of the 2 Amp fuses from the transfer switch.
FC_8 will display on the system control panel. Carefully
reinstall the fuse in the transfer switch, then turn the system
switch to OFF for 30 seconds to clear the fault.
Analyze Test Results
If any test procedure above does not cause the generator
to shut down and display the indicated fault, repair the fault
condition before putting the unit into service.
