Setting Exercise Timer

The 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 generator to
exercise.
2. On that day and time, press and hold "SET EXERCISE"
for three seconds.
The "Set Exercise" display will illuminate then turn off
to confirm that the exercise timer has been set. Then
release the button.
The unit will crank and run the exercise cycle. During
the cycle, "Set Exercise" will illuminate.
Once the exercise cycle is complete, the unit will turn
off and "Set Exercise" will no longer be displayed.
The exercise cycle may be discontinued at anytime by
turning the System Switch to OFF.
3. The unit will then start and run it's 20 minute exercise
cycle weekly.
For example, if you press SET EXERCISE on Sunday morning
at 10:00 AM, the unit will run an immediate exercise cycle n an imm n an imme
and an exercise cycle every following Sunday at 10:00 AM
(+/- 1/2 hour).
"Set Exercise" will only work if the unit is in the AUTO 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 starting battery is disconnected.
If your 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.
Generator will not exercise if timer is not set.

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.
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.

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 control pane control pane
fault codes, like "FC_1". The table below lists the detected ke "FC_1". T e "FC_1".

The remote LED indicator can be installed at a convenient
inside location. The LED will remain lit when the generator
is in AUTO. Should a system fault be detected, the LED will
turn on and off in a series of blinks that identify the problem.
The blink pattern is repeated with a brief pause between each
series of blinks.
