Automatic Generator Exerciser
The automatic generator exerciser comes preset with
a 28-day exerciser schedule (the customer unit’s preset day
cycle may vary due to specifications from the generator supplier).
The exerciser, when enabled, will automatically start the
generator every twenty-eighth day and run the unit loaded
or unloaded for 10 minutes. The exerciser interval is
selectable through (JP) jumper selection on the con-
troller board. The selections are 7, 14, 21 or 28 day.
Selecting Exerciser Without Transfer
To start the automatic exerciser without transfer, depress
the Exerciser Start/Stop button. The generator will start
and run for 10 minutes.
* Once this first exercise is com-
plete, the generator
LED will flash at a 1-second interval
indicating the exerciser is enabled. Once the exerciser
times out (7, 14, 21 or 28 day interval), the generator
will start and run again for 10 minutes. This will repeat
until the exerciser is disabled. To stop the exerciser mode,
depress the exerciser Start/Stop again and the generator
light will stop flashing, indicating the exerciser mode
has been canceled.
Selecting Exerciser With Transfer
To enable the automatic exerciser with transfer, depress
the Exerciser Start/Stop button and the transfer button.
The generator will start and the load will be transferred to
the generator. After 10 minutes
*, the load will be transferred
back to the utility. Once this first exercise is complete, the
generator
LED and the Generator position LED will flash
at a 1-second interval indicating the exerciser is enabled.
Once the exerciser has timed out (7, 14, 21 or 28 day
interval), the generator will start and transfer the load
to Generator power for 10 minutes. At the end of this
10-minute period, the unit will transfer the load back to
the utility and the generator will shut off. This will repeat
until the exerciser is disabled. To stop the exerciser
mode, depress the exerciser Start/Stop again and the
generator light will stop flashing, indicating the exerciser
mode has been canceled.
