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 generating set down if the generating set
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 generating set 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 generating set 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 generating set. 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.
High Oil Temperature
This service code is indicated by High Oil Temperature
scrolling across the digital display. The contacts
of the temperature switch are normally open. If the
engine temperature increases past a determinded
temperature, the service code 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, 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 Transfer Switch
Service 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.
Battery Charge Circuit
This service code is indicated by Battery Charge
Circuit scrolling across the digital display. The most
likely cause is an electrical problem with the control
panel. To remedy the problem, contact your installer or
an authorized dealer.
