Over Voltage
This service code is indicated by
Over Voltage
scrolling
across the digital display. This feature protects devices
connected to the transfer switch by shutting the generator
down if the generator output voltage happens to increase
above the preset limit.
This condition is most likely caused by a failed voltage
regulator, alternator excitation circuit or a load imbalance. To
remedy the problem, contact your installer or an
authorized dealer.
Engine Does Not Start
This service code is indicated by
Engine Does Not Start
scrolling across the digital display. 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.
The most likely cause of this problem is no fuel supply or
incorrect fuel setting. See
Fuel Conversion
in the installation
manual. Check the internal and external fuel shut off valves
to ensure they are fully open. Other causes could be failed
spark plug(s), a 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 service code is indicated by
Low Frequency
scrolling
across the digital display. 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 resolve the problem,
contact your installer or an authorized dealer.
Engine Overspeed
This service code is indicated by
Engine Overspeed
scrolling
across the digital display. To resolve the problem, contact
your installer or an authorized dealer.

Common causes for this condition include running the unit
with access panels removed, obstructed air inlet or exhaust
port, or debris in the engine compartment or running unit
with roof open.
To resolve the problem, let the engine cool down and remove
any accumulated debris and obstructions. Ensure that the
access panels are installed and the roof is closed whenever
the unit is running.
If problem persists, contact your installer
or authorized dealer.
Transfer Switch Service code
This service code is indicated by

code
scrolling across the digital display (if transfer switch is
equipped with service code detection).
The most likely cause of this service code is a blown fuse
in the transfer switch. To remedy the problem, contact your
installer or an authorized dealer.

This service code is indicated by No Monitor Communication
scrolling across the digital display. The SERVICE NEEDED red
LED on the wireless monitor will flash 20 fast pulses, pause
5 seconds, and repeat if there is a loss in communication
between the wireless monitor and the generator.
To resolve the problem, move the wireless monitor closer to
generator. Re-link if necessary.
