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.
The generator's control panel has a digital display to show
fault codes. An extra LED indicator is installed at a
convenient inside location.The LED will turn on and off in a
series of blinks if certain problems are detected in your
HGS.The blink pattern is repeated with a brief pause
between each series.The fault code as shown on the
control panel, and the number of blinks on the mounting
plate, indicates the detected fault and as follows:
Fault Codes / LED Flashes
FC_1 / 1
FC_2 / 2
FC_3 / 3
FC_4 / 4
FC_5 / 5
FC_6 / 6
FC_7 / 7
FC_8 / 8

Reset Fault Detection System

The operator must reset the fault detection system each
time it activates.To do so, place the system switch in the
OFF position for 5 seconds or more. Return the Home
Generator System to service after correcting the problem
by placing the system 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.
MAINTENANCE
Fault Description

Low battery voltage

Low oil pressure

Low voltage
Engine fail to start
Low frequency
Engine overspeed
Oil temperature high
Transfer switch fault
Low Battery Voltage
This fault is indicated by fault code FC_1 and one blink on
the LED indicator.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 fault code FC_2 and two blinks on
the LED indicator.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 20 seconds and diagnostic LED
will flash. In this case, contact an authorized service facility.
