Low oil Pressure
This service code is indicated by
Low Oil Pressure
scrolling
across the digital display and two flashes on the wireless
monitor. 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 will
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 service code code will
appear. In this case, contact an authorized dealer.
Under Voltage
This service code is indicated by Under Voltage scrolling
across the digital display and three flashes on the wireless
monitor. This condition is caused by a restriction in the
fuel flow, the electronic governing system not functioning
properly, a broken or disconnected signal lead, a failed
alternator winding, the control board circuit breaker is open,
or the generator is overloaded.
To remedy the problem, contact your installer or an
authorized dealer.
over Voltage
This service code is indicated by
Over Voltage
scrolling across
the digital display and three flashes on the wireless monitor.
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 and four flashes on the
wireless monitor. 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 selector setting. See Fuel Selection Switch 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 loose electronic governor
connection, 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 and five flashes on the wireless
monitor. 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, electronic govenor
system, 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 and six flashes on the wireless
monitor. This condition can be caused by a problem within
the electronic govenor system.
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 and seven flashes on the
wireless monitor. The contacts of the temperature switch
are normally open. If the engine temperature exceeds a
predetermind temperature, the service code is detected and
the engine shuts down.
Common causes for this condition include running the
unit with an access doors 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 doors are installed and the roof is closed whenever
the unit is running. If problem persists, contact your installer
or an 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) and eight flashes on
the wireless monitor.
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.
no Wireless communication
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.
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.
