Low Voltage (Generator)
This fault is indicated by three blinks.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 Home Standby
Generator is overloaded.
To remedy the problem, contact your local service center.
Engine Fail To Start
This fault is indicated by four blinks.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 15 seconds, pause for 15 seconds, crank for
15 seconds, pause for 15 seconds, and repeat. If the system
does not begin producing electricity after approximately
90 seconds, the unit will stop cranking and the LED will
blink.
The most likely cause of this problem is no fuel supply.
Check the inside and outside 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
This fault is indicated by 5 blinks.This feature protects
devices connected to the transfer switch by shutting the
generator down if the engine runs slower than the preset
limit.
This condition is caused by a failed engine governor or by
excessive loads on the generator.To remedy the problem,
you may need to contact your installer or local service
center for assistance.
Engine Overspeed
This fault is indicated by 6 blinks.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 runs at 72 Hz for five
seconds, the generator will shut down.
• If the generator output frequency reaches 75 Hz, the
generator will shut down instantly.
This condition is caused by a failed engine governor.To
remedy the problem, you should contact your installer or
local service center for assistance.
Oil Temperature High
This fault is indicated by seven blinks.The contacts of the
temperature switch (Figure 4) are normally open. If the
engine oil temperature exceeds approximately 140°C
(284°F), the fault is detected and the engine shuts down.
Common causes for this condition include running the unit
with all access doors removed, obstructed air inlet or
exhaust port, low oil level, or debris in the engine cylinder
cooling fins.
To resolve the problem, remove any accumulated debris
and obstructions and let the engine cool down. Ensure that
the Oil Service door and/or the Control Panel door is
installed whenever the unit is running.
