Maintenance
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.
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.
Servicing the 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.

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 (if removed), 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
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
battery charge circuit.
Remove the 15 Amp fuse and disconnect the battery from
the generator. Take the battery to a local battery store for
analysis. Or contact your local service center for assistance.
Reinstall the battery (replace if necessary - see Battery in
Final Installation Considerations
in the installation manual).
Then reset the fault detection system, as described earlier.
