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 HGS.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 belo_

A description of each fault and suggested remedies are as
follows:
No Blinks -'Dead'
Unit
This condition is caused by a completely dead starting
battery.To remedy the problem, remove the 15Amp fuse
and disconnect the battery from the generator.Take the
battery to a local battery store for analysis.
Replace the battery in the battery compartment
after it has
been fully recharged, connecting the NEGATIVE cable last.
Install the IS Amp fuse. Reset the Fault Detection system
as described above,
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 'turn-over' the
engine. Causes for this problem may be a failed battery or a
failed trickle charger circuit
To remedy the problem, remove the 15Amp fuse and
disconnect the battery from the generator.Take the battery
to a local battery store for analysis.
Replace the battery
in the battery
compartment
after it has
been fully recharged, connecting
the NEGATIVE
cable last.
Install the I S Amp fuse. Reset the Fault Detection
system
as described
above. Check

charge output_
Low Oil Pressure
This fault is indicated by two blinks.The unit is equipped
with an oil pressure switch (Figure 5) 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, fix any obvious
oil leak and/or add the recommended oil to the FULL mark
on the dipstick. Reset the Fault Detection system as
described above.
If low oil pressure condition still exists, engine will start,
then shut down after about 10 seconds and diagnosticLED
will flash, In this case, contact an authorized service facility.
