Briggs & Stratton Home Generator System Installation & Start-Up Manual page 18

FC_4 - Engine Does Not 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
With the system switch in AUTO position, push
MANUAL OVER-RIDE to start the generator. Locate the
governor lever and SLOWLY lower engine speed. Do NOT
change engine speed using the governor adjustment. When
the generator reaches a speed slower than 55 Hz for three
seconds the generator will shut down and FC_5 will be
displayed on the system control panel. Turn the system
switch to OFF for 30 seconds to clear the fault.
FC_6 - Engine Overspeed
With the system switch in AUTO position, push
MANUAL OVER-RIDE to start the generator. Locate the
governor lever and SLOWLY raise engine speed. Do NOT
change engine speed using the governor adjustment.
When the generator output frequency is 65-70 Hz after
three seconds the generator will shut down and FC_6 will
be displayed on the system control panel. If the generator
output frequency is greater than 70 Hz the generator will
shut down immediately. Turn the system switch to OFF for
30 seconds to clear the fault.
FC_7 - High Temperature
Locate wire #95 connected to the temperature switch.
Shown here is the temperature switch (A) and the oil filter

Shown here is the temperature switch (A) and the oil filter
location (B) for the 15kW generator:
Connect an installer-supplied jumper wire to wire
#95. With the system switch in AUTO position, push
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
