Reset Fault Detection System
The operator must reset the fault detection system each
time it activates. To do so, place the control panel system
switch in the OFF position for 30 seconds or more. Remedy
the fault condition, then return the generator to service by
placing the system switch in the AUTO position, installing
the 15 Amp fuse, and resetting the exercise timer. See
Setting Exercise Timer in Operation.
A description of each fault and suggested remedies are
asfollows:
No LED - Discharged Battery
If there is a detected fault condition but the optional remote
LED indicator is not blinking, this is because the battery is
completely discharged. To remedy the problem, remove the
15 Amp fuse and disconnect the battery from the generator.
Take the battery to a local battery store for analysis. Reinstall
battery after it has been fully recharged, connecting the
NEGATIVE cable last. Then reset the fault detection system,
as described earlier.
Low Battery Voltage (FC_1)
This fault is indicated by fault code FC_1 and one blink
on the remote LED indicator. This condition occurs if the
generator cannot start because the starting battery output
power is below that needed to crank the engine. Causes for
this problem may be a faulty battery or battery charge circuit.
To remedy the problem, contact your local service center to
check the battery charge output. Remove the 15 Amp fuse
and disconnect the battery from the generator. Take the
battery to a local battery store for analysis.
Reinstall the battery (replace if necessary - see Battery in
Final Installation Considerations in the installation manual).
Then reset the fault detection system, as described earlier.
Low Oil Pressure (FC_2)
This fault is indicated by fault code FC_2 and two blinks on
the remote LED indicator. The unit is equipped with an oil
pressure switch that uses normally closed contacts held
open by engine oil pressure during operation. Should oil
pressure drop below the 8 psi range, switch contacts close
and the engine is shut down.
To remedy the low oil pressure condition, add the
recommended oil to the FULL mark on the dipstick.
If the low oil pressure condition still exists, the engine will
start, then shut down again. The fault code will appear and
the LED will flash. In this case, contact an authorized dealer.
Low Voltage (Generator, FC_3)
This fault is indicated by fault code FC_3 and three blinks
on the remote LED indicator. This condition is caused by a
restriction in the fuel flow, a broken or disconnected signal
lead, a failed alternator winding, the control panel circuit
breaker is open, or the generator is overloaded.
To remedy the problem, contact your installer or an
authorized dealer.
Engine Does Not Start (FC_4)
This fault is indicated by fault code FC_4 and four blinks on
the remote LED indicator. This feature prevents the generator
from damaging itself if it continually attempts to start in
spite of another problem, such as no fuel supply. Each
time the system is directed to start, the unit will crank for
10 seconds, pause for 10 seconds, and repeat. If the system
does not begin producing electricity after approximately
2minutes, the unit will stop cranking and the LED will blink.
Check to make sure the generator’s circuit breaker is in the
ON position in order for the sensing leads to verify that the
unit is running.
The most likely cause of this problem is no fuel supply.
Check the internal and external fuel shut off valves to
ensure they are fully open. Other causes could be failed
spark plug(s), failed engine ignition, or the engine air filter
is clogged. You may need to contact your installer for
assistance if you can’t remedy these problems.
Low Frequency (FC_5)
This fault is indicated by fault code FC_5 and five blinks
on the remote LED indicator. This feature protects devices
connected to the transfer switch by shutting the generator
down if the engine runs slower than 55 Hz for three seconds.
This condition is caused by a failed engine component or by
excessive loads on the generator. To remedy the problem,
contact your installer or an authorized dealer.
Engine Overspeed (FC_6)
This fault is indicated by fault code FC_6 and six blinks
on the remote LED indicator. This feature protects devices
connected to the transfer switch by shutting the generator
down if the engine happens to run faster than the preset
limit. The overspeed fault is detected as follows:
t *GUIFHFOFSBUPSPVUQVUGSFRVFODZJT)[BGUFS
three seconds, the generator will shut down.
t *GUIFHFOFSBUPSPVUQVUGSFRVFODZJTHSFBUFSUIBO)[
the generator will shut down immediately.
This condition is caused by a failed engine component.
To remedy the problem, contact your installer or an
authorizeddealer.
