5. About 5 seconds after the generator (alter-
nate source) acceptable light comes on, the auto-
matic transfer switch should transfer the load from
the utility to the generator. At that time the Transfer
Switch on generator light should come on.
6. The generator will stay connected to the load
for about 5 minutes at which time the transfer switch
will transfer the load back to the utility. At the time it
transfers back to utility the Transfer Switch on Utility
light should come on and the Transfer Switch on
generator light should go out. To bypass this five
minute time delay you can press and release the
Push to Test button again at any time.
7. After the load retransfer to the utility, the gen-
erator will continue to run for about minute (without
a load) and then shut down. The Generator ac-
ceptable light will go off indicating the generator set
has shut down. This completes the functional test
of the transfer switch and the generator set. If you
want to leave the generator in the Automatic Start
mode you can leave the engine control module in
the auto mode. If you have additional work to do or
don’t want to leave the engine generator set in the
automatic position start mode press and release the
stop/reset button In the off mode the engine genera-
tor set will not start or run.
GENERATOR EXERCISER CIRCUIT
The automatic generator exerciser is configured to
automatically exercise the generator for 20 minutes
once every 4 days.
In order to set and test the exercise circuit the
engine control module must be set in the auto

SETTING THE EXERCISER CIRCUIT
Press and release the Automatic Generator Exer-
ciser button. After about 8 seconds the exerciser
light flashes 4 times to indicate that the exerciser
circuit has been set. The number of flashes indi-
cates the number of days until the next exercise
period. This 20 minute period will occur at approxi-
mately the same time of the day the button was
pressed.
DISABLING THE EXERCISER CIRCUIT
Press and hold the Automatic Generator Exerciser
button until the light goes off, the light flashes then
goes off.
ENABLING THE EXERCISER CIRCUIT
