ferred 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 set stops and the Generator
acceptacle light goes off.
WITH Load Transfer
. Press and hold the Push to Test button until
the generator (alternate source) acceptable light
comes on and stays on. Then release the button.
This will start up your generator set.
This light indicates that the generator is running and
the output voltage and frequency are within accept-
able limits. Under normal conditions this light should
come on in 5 to 0 seconds. If the light does not
come on and stay on a malfunction has occurred.
Either the unit didn’t start or the voltage or frequency
is incorrect. Correct the problem before continuing.
2. 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.
3. 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.
4. After the load retransfers to the utility, the gen-
erator will continue to run for about  minute (without
a load) and then shut down. The generator accept-
able 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 left hand toggle switch on the generator in
the ON position. If you have additional work to do
or don’t want to leave the engine generator set in
the automatic position start mode move the toggle
switch to the OFF position. In the OFF postion the
alarm light will come on and the generator 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
left hand toggle switch on the generator control
panel must be in the ON position.
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
Press and hold the Automatic Generator Exerciser
button until the light goes off, the light flashes then

flashes fourteen times to indicate that the exerciser
circuit has be re-enabled.

CLEARING AN “ERROR” CODE
An error codes occurs on the ASCO control board if
the generator set fails to start or there is some other
malfunction. BOTH Transfer Switch lights will be
blinking together. The Automatic Generator Exer-
