Maintenance

Servicing the System

To service system:
1. Remove 15 Amp fuse from control panel.
. Set the system switch to OFF.
3. Set the generator's main circuit breaker to its
OFF position.
4. Utility voltage is present. Disconnect power before
servicing by removing the two fuses from the
transfer switch.

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, and
the number of LED flashes (also described as 'blinks') seen
on the remote LED indicator.
Fault Description
Low battery voltage FC_1
Low oil pressure FC_
Low voltage FC_3
Engine fails to start FC_4
Low frequency FC_5
Engine overspeed FC_6
High temperature FC_7
Transfer switch fault FC_8
The remote LED indicator is installed at a convenient inside
location. The LED will remain lit when the generator is in
AUTO. The LED will turn on and off in a series of blinks that
correspond to the fault detected in your residential generator.
The blink pattern is repeated with a brief pause between each
series of blinks.
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. Remedy the fault condition,
then return the residential generator to service by placing the
system switch in the AUTO position.

A description of each fault and suggested remedies are
as follows:
No LED - Discharged Battery
If there is a detected fault condition but the LED is not
blinking, this is because the battery is completely discharged.
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 ONLY with same
type battery as described in Battery in Operation. Replace
the battery after it has been fully recharged, connecting the
NEGATIVE cable last. Then install the 15 Amp fuse in the
control panel.
NOTE: With the battery installed, all wiring to transfer
switch and residential generator completed, utility power
supplied to the automatic transfer switch, and the unit in
AUTO mode, the battery receives a trickle charge while
the engine is not running. The trickle charge is not able
to recharge a battery that is completely discharged. See
Battery in Maintenance.
Low Battery Voltage (FC_1)
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 battery charge circuit.
To remedy the problem, contact your local service center
to check the battery 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
ONLY with same type battery as described in Battery
in Operation.
Replace the battery after it has been fully recharged,
connecting the NEGATIVE cable last. Then install the 15 Amp
fuse in control panel and reset exercise timer. See Setting
Exercise Timer in Operation.
Low Oil Pressure (FC_2)
This fault is indicated by fault code FC_ and two blinks on
the remote LED indicator. The unit is equipped with an oil
pressure switch (A).
