Maintenance; Fault Detection System - GE HOME GENERATOR SYSTEMS Operator's Manual

Maintenance

Servicing the System
Before performing any generator maintenance, always
perform the following steps:
1. Set generator's circuit breaker to its OFF position.
2. Set control panel system switch to OFF.
3. Remove 15 Amp fuse from control panel.

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 temperature, over speed, and
other conditions.
The generator's control panel has a digital display that
shows fault codes, like "FC_1". The table below lists the
detected fault, the fault code as displayed on the control
panel.
Fault Description
Low battery voltage
Low oil pressure
Low voltage
Engine does not start
Low frequency
Engine overspeed
High temperature
Transfer switch fault

Reset Fault Detection System
The operator must reset the fault detection system each time
it activates. To do so, place the control panel system switch
in the OFF position for 30 seconds or more. Remedy the
fault condition, then return the home generator to service
by placing the system switch in the AUTO position, installing
the 15 Amp fuse, and resetting the exercise timer. See Setting
Exercise Timer in Operation.
Low Battery Voltage (FC_1)
This fault is indicated by fault code FC_1. This condition
Fault Codes
occurs if the generator cannot start because the starting
FC_1
battery output power is below that needed to crank the
engine. Causes for this problem may be a faulty battery or
FC_2
battery charge circuit.
FC_3
To remedy the problem, contact your local service center to
FC_4
check the battery charge output. Remove the 15 Amp fuse
FC_5
and disconnect the battery from the generator. Take the
FC_6
battery to a local battery store for analysis.
FC_7
Reinstall the battery (replace if necessary - see Battery in
FC_8
Final Installation Considerations in the installation manual).
Then reset the fault detection system, as described earlier.
4. Utility voltage is present at generator control panel.
Disconnect power before servicing control panel by
removing the fuses from the transfer switch.
5. After all servicing has been completed, replace fuses
in transfer switch, replace 15 Amp fuse in control
panel, set system switch and circuit breaker ON
and reset exercise timer. See Setting Exercise Timer
in Operation.
