Operation
Automatic Operation Sequence
The generator’s control panel houses a logic control circuit
board. This control board constantly monitors utility power
source voltage. Should that voltage drop below a preset
level, control board action will signal the engine to crank
and start.
When utility source voltage is restored above a preset
voltage level, the engine is signaled to shut down.
The actual system operation is not adjustable and is
sequenced by sensors and timers on the control board,
as follows:

of the nominal supply voltage, the sensor energizes

brown-outs.

Utility Voltage Pickup Sensor
This sensor monitors utility power supply voltage. When that
voltage is restored above 80 percent of the nominal source
voltage, a time delay starts timing and the engine will go to
engine cool-down.

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).

(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

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 the

to confirm that the exercise timer has been set. Then
release the button.
The unit will crank and run the exercise cycle. During

The exercise cycle may be discontinued at anytime by
turning the System Switch to OFF.
3. The unit will then start and run its 20 minute
exercise cycle.
For example, if you press SET EXERCISE on Sunday morning
at 10:00 AM, the unit is set to run an exercise cycle every
Sunday at 10:00 AM (+/- 1/2 hour).

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.

Generator will not exercise if timer is not set.
Installation Inspection
Before placing the generator system into service, inspect the
entire installation carefully.
This completes the installation and start-up instructions.
