FAULT DETECTION
SYSTEM
The generator may have to run for long periods of time
with no operator present. For that reason, the system is
equipped with sensors that automatically shut down the
generator in the event of potentially damaging conditions,
such as low oil pressure, high oil temperature, over speed,
and other conditions.
A light on the generator's control panel is called the
Diagnostic LED.A similar LED indicator is installed at a
convenient inside location. Both LED's will turn on and off
in the same series of blinks if certain problems are
detected in your HSG.The blink pattern is repeated with a
brief pause between each series.The number of blinks in
the series indicates the detected fault, as listed near the
control panel, on the mounting plate and as follows:
Number of LED Flashes Fault Description
I Low battery voltage
2 Low oil pressure
3 Low voltage
4 Engine fail to start
5 Low frequency
6 Engine overspeed
7 Oil temperature high
_I ........... _ [o_1 I_'_I_IL_ F_I"- _ _
Reset Fault Detection System
The operator must reset the fault detection system each
time it activates.To do so, place the AUTO/OFF/MANUAL
switch in the OFF position for 30 seconds or more.
Return the Home Standby Generator to service after
correcting the problem by placing the
AUTO/OFF/MANUAL switch in the AUTO position.
A description of each fault and suggested remedies are as
follows:
No LED - Discharged Battery
This condition is caused by a completely discharged
battery.To remedy the problem, remove the 15 Amp fuse
and disconnect the battery from the generator.Take the
battery to a local battery store for analysis.
Replace the battery after it has been fully recharged,
connecting the NEGATIVE cable last. Install the 15 Amp
fuse.
Low Battery Voltage
This fault is indicated by one blink.This condition occurs if
the generator cannot start because the starting battery
output power is below that needed to crank the engine.
Causes for this problem may be a faulty battery or trickle
charger circuit.
To remedy the problem, contact your local service center
to check the battery trickle charge output. Remove the
15 Amp fuse and disconnect the battery from the generator.
Take the battery to a local battery store for analysis.
Replace the battery after it has been fully recharged,
connecting the NEGATIVE cable last. Install the 15 Amp fuse.
Low Oil Pressure
This fault is indicated by two blinks.The unit is equipped
with an oil pressure switch (Figure 4) using normally closed
contacts that are held open by engine oil pressure during
operation. Should oil pressure drop below the 8 psi range,
switch contacts close and the engine is shut down.
To remedy the low oil pressure condition, add the
recommended oil to the FULL mark on the dipstick.

If low oil pressure condition still exists, engine will start,
then shut down after about 10 seconds and diagnostic LED
will flash. In this case, contact an authorized service facility.
