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 connected to the oil pressure switch (
a
):
Connect an installer-supplied jumper wire to wire #85.
With the system switch in
auto
position, push the manual
over-ride switch 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 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 and hold
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 and hold
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 (
B
):
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
Verify that utility power is present at the Automatic Transfer
Switch. With the system switch in
auto
position, remove
one of the 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.
