Setting Exercise Timer

The home generator is equipped with an exercise timer that
will start and exercise the system once every seven days.
During this exercise period, the unit runs for approximately
20 minutes and then shuts down. Electrical load transfer
DOES NOT occur during the exercise cycle (unless an utility
power outage occurs).
A button on the control panel is labeled "Set Exercise" (see
System Control Panel). The specific day and the specific
time of day this button is pressed is programmed into the
control board memory. This date and time is then used
to automatically initiate the system exercise cycle. The
"SET EXERCISE" legend on the control panel will flash until
the set exercise cycle is set.
To perform the Set Exercise procedure:
1. Choose the day and time you want your home generator
to exercise.
2. On that day and time, press and hold down the
"Set Exercise" button for three seconds.
NOTE: "SET EXERCISE" will flash until the button is pressed
for three seconds, then "SET EXERCISE" will illuminate for
5 seconds, and finally turn off.
For example, if you press the "Set Exercise" button on
Sunday morning at 10:00 AM, the unit will run an exercise
cycle the following Sunday at 10:00 AM (+/- 1/2 hour).
NOTE: "Set Exercise" will only work if the unit is in the
Automatic mode and this exact procedure is followed. The
exerciser will need to be re-set if the 15 Amp fuse is removed
or changed, or if the 12 Volt DC battery is disconnected.
If you want to change the day and time the unit exercises,
simply perform the "Set Exercise" procedure at the exact
weekday and time you want it to take place.

Maintenance

Servicing the System

To service system:
1. Set the system switch to OFF.
2. Set the generator's main circuit breaker to its OFF
position.
3. Utility voltage is present. Disconnect power before
servicing by removing the two 2 Amp 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 oil 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 blinks seen on the remote LED indicator.
Fault Description
Low battery voltage
Low oil pressure
Low voltage
Engine fails to start
Low frequency
Engine overspeed
Oil temperature high
Transfer switch fault
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 home 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 home generator to service by placing the
system switch in the AUTO position.
