Status indicator LED’s relay conditions of generator

function for user or service technician convenience.
Illumination of these indicator LED’s communicate
conditions that require generator service but are not
severe enough to cause damage if the generator is
allowed to operate. Contact a qualified service technician
immediately for service if any of the listed LED’s are lit,
even if the generator appears to function normally.

LOW BATTERY

The Low Battery LED is will illuminate Red when
the cranking battery voltage falls below 11.0
volts. At this level, the battery begins to lose the
ability to consistently start the engine. Causes of
low battery voltage may include a failing battery,
failed battery charger or failed engine alternator.

ENGINE RUN

The Engine Run LED illuminates Green when
the generators engine is running. This is the only
light lit when the generator is supplying power as
intended.

Fault lights relay conditions that may cause damage

to the generator and/or loads connected to the output of
the generator. When any of the listed situations occur
while the generator is running, the generator is shut
down and the fault light associated with the shutdown
cause is lit. Once the light is lit, it remains on until it is
cleared by pressing the OFF button on the control panel.
If a fault light is lit, determine and correct the cause of the
problem before restarting the generator. During
generator starting, the controller ignores fault conditions
until 15 seconds after the generator starts, then
uncleared faults will once again cause the generator to
shut off. To determine possible fault causes, refer to the
troubleshooting section of this manual or contact a
qualified service technician for assistance.

HIGH TEMPERATURE

The High Temperature LED illuminates Red if
the temperature of the engine becomes too high.
Engine oil temperature is monitored while the
engine is active and the engine is shut off to
avoid damage if the oil temperature becomes too
high. When operating the generator in
temperatures above the maximum listed on the
nameplate, it is necessary to reduce the load
connected to the generator to avoid overheating.
If high ambient temperatures or excessive loads
are eliminated as possible causes of High
Temperature shutdown, check to insure cabinet
openings are not restricted by debris.

LOW OIL

The Low Oil LED illuminates Red and the
engine is shut off if the engine oil pressure falls

too low. To avoid engine damage, engine oil
pressure is monitored to determine the amount
of oil in the engine. When pressure falls below a
preset level, a Low Oil fault occurs. Check for
proper oil level if the generator shuts down due
to a Low Oil alarm.

OVERCRANK

The Overcrank LED is illuminated Red if all three
10 second cyclic crank attempts are
unsuccessful in starting the engine. Once the
light is on, the generator does not attempt to start
until the fault is reset. When the Overcrank LED
is lit, verify fuel is available at the inlet to the unit,
then check the condition of the cranking battery.

OVERSPEED

The Overspeed LED is illuminated Red if the
generator engine is running too fast. Electrical
output of the generator at high speeds may
damage loads connected to the generator output
and/or engine failure may occur at excessive
speeds. If the generator shuts down on an
Overspeed error, seek assistance from a
qualified generator service technician.

LOSS SPEED

The Loss Speed LED is illuminated Red if the
generator engine is running too slow. Electrical
output of the generator at low speeds can
damage loads connected to the generator output
and/or generator failure may occur due to
excessive heating in the generator head. If the
generator turns off due to an Loss Speed error,
check to see that the connected loads do not
exceed the nameplate rating of the generator.

AUX 1

This is a common alarm, it flashes when there is
a failure or alarm. A signal is sent to the transfer
switch and illuminates the generator failure LED
located on the transfer switch.
