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 Does Not 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 doors 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 doors 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.
Generator Maintenance
The generator warranty does not cover items that have been
subjected to operator abuse or neglect. To receive full value
from the warranty, the operator must maintain the system as
instructed in the engine operator’s manual.
All adjustments should be made at least once each season.
Follow the requirements in the engine operator’s manual.
Generator maintenance consists of keeping the unit
clean. Operate the unit in an environment where it will
not be exposed to excessive dust, dirt, moisture or any
corrosive vapors. Cooling air louvers on the enclosure
must not become clogged with snow, leaves, or any other
foreign material. To prevent generator damage caused by
overheating, keep the enclosure cooling inlets and outlets
clean and unobstructed at all times.
Check the cleanliness of the unit frequently and clean when
dust, dirt, oil, moisture or other foreign substances are
visible on its exterior/interior surface. Inspect the air inlet
and outlet openings inside and outside the enclosure to
ensure air flow is not blocked.
DO NOT use direct spray from a garden hose to clean
generator. Water can enter the engine and generator and
cause problems.
