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 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 Fail To Start (FC_4)
This fault is indicated by fault code FC_4 and four blinks on
the 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 2 minutes,
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 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
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:
• If the generator output frequency is 65-70 Hz, after
three seconds, the generator will shut down.
• If the generator output frequency is greater than
70 Hz, the generator will shut down immediately.
This condition is caused by a failed engine component.
To remedy the problem, contact your installer or an
authorized dealer.
High Temperature (FC_7)
This fault is indicated by fault code FC_7 and seven blinks on
the LED indicator. The contacts of the temperature switch
are normally open. If the engine temperature exceeds
approximately 149°C (300°F), the fault is detected and the
engine shuts down.
Common causes for this condition include running the unit
with access panels removed, obstructed air inlet or exhaust
port, low oil level, or debris in the engine cylinder cooling fins.
To resolve the problem, let the engine cool down and remove
any accumulated debris and obstructions. Ensure that all
access panels are installed whenever the unit is running.
Transfer Switch Fault (FC_8)
This fault is indicated by fault code FC_8 and eight blinks
on the LED indicator (if transfer switch is equipped with
fault detection).
The most likely cause of this fault is a blown fuse in the
transfer switch. To remedy the problem, contact your
installer or an authorized dealer.
