AUTOMATIC GENERATOR EXERCISER
The automatic generator exerciser automatically exercises
the generator for 20 minutes once every 14 days.
TO SET EXERCISER
Press and release the Automatic Generator Exerciser but-
ton. After about 8 seconds the exerciser light flashes 14 times
to indicate that the exerciser has been set. The number of
flashes indicates the number of days until the next exercise pe-
riod (at approximately the same time the button was pressed).
TO DISABLE EXERCISER
Press and hold the Automatic Generator Exerciser button
until the light above the button goes off (light flashes then
goes off). The exerciser is now disabled and the light is off.
TO ENABLE EXERCISER
Press and hold the Automatic Generator Exerciser button
until the light goes off (light flashes then goes off). Exerciser
is now enabled. After about 8 seconds exerciser light flashes 14
times to indicate that the exerciser has been re–enabled.
Note: With a total power failure (utility failure and generator
fails to start) the exerciser must be reset after power is
restored.

MANUAL GENERATOR TESTING
GENERATOR TEST WITH LOAD TRANSFER
During this test a utility failure is simulated. The generator
starts and the load transfers to the generator. Then the load
retransfers back to the utility and generator stops.
1. Press and hold the
Push to Test button until the
GENERATOR acceptable light comes on and stays on
(the generator cranks and starts).
2. The automatic transfer switch waits 15 seconds to allow the
generator to warm up. Then it transfers the load to the
generator. The TRANSFER
SWITCH on generator
(alternate source) light
comes on.
3. After 5 minutes the auto–
matic transfer switch re–
transfers the load back to
the utility. To bypass the
time delay, press and
release the Push to Test
button again. The TRANS–
FER SWITCH on utility
(preferred source) light
comes on.
4. After load retransfer the
generator will continue to
run unloaded for one min-
ute for engine cooldown.
Then it is stopped. The
GENERATOR acceptable
light goes off.
GENERATOR TEST WITHOUT LOAD TRANSFER
During the test the generator cranks and starts and the
GENERATOR light comes on (if it is acceptable). After
running for 20 minutes it stops. Throughout the test the load
remains connected to the utility (the automatic transfer
switch does not transfer the load to the generator).
1. Press and release (do not hold) the
Push to Test button.
The generator cranks and starts, and the GENERATOR
acceptable light comes on and stays on.
2. The generator runs for 20
minutes. The automatic
transfer switch does not
transfer the load to the
generator. The TRANS-
FER SWITCH on utility
(preferred source) light
stays on.
3. To bypass the time delay or
cancel the test, press and
release the
Push to Test
button again.
4. The generator stops and
the GENERATOR accept-
able light goes off.
