PERSONAL INJURY HAZARD - Install front cover in
transfer switch before operation. An electrical system
fault could cause a flash and severe personal injury
2. Turn on the preferred source (utility) circuit breaker.
The utility source acceptable light should now come on
as well as the transfer switch on utility light. If these
lights fail to come on recheck your incoming power to
insure you have 240 volts nominal. If not, troubleshoot
your utility source before continuing.
3. Turn on the alternate source (generator) circuit
breaker.
4. 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 acceptable
limits. Under normal conditions this light should come
on in 5 to 10 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.
5. About 15 seconds after the generator (alternate
source) acceptable light comes on , the automatic
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 retransfers to the utility the generator
will continue to run for about 1 minute (without a load)
and then shut down. The Generator acceptable 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 right hand
toggle switch on the generator in the normal position. If
you have additional work to do or don’t want to leave the
engine generator set in the automatic start mode move
the toggle switch to the stop position. In the stop position
the alarm light will come on and the engine generator set
will not start or run.
GENERATOR EXERCISER CIRCUIT
The automatic generator exerciser is configured to
automatically exercise to generator for 20 minutes once
every fourteen days .
In order to set and test the exercise circuit the right
hand toggle switch on the generator control panel
must be in the normal position.
SETTING THE EXERCISER CIRCUIT
Press and release the Automatic Generator Exerciser
button. After about 8 seconds the exerciser light flashes
14 times to indicate that the exerciser circuit has been set.
The number of flashes indicates the number of days until
the next exercise period. This 20 minute period will occur
at approximately 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 above the button goes off, the light
flashes and then goes off.
ENABLING THE EXERCISER CIRCUIT
Press and hold the Automatic Generator Exerciser
button until the light goes off, the light flashes then goes
off. After about 8 seconds the exerciser light flashes
fourteen times to indicate that the exerciser circuit has
been re-enabled.

***** WARNING *****
*************
WITH A TOTAL POWER FAILURE (UTILITY POWER
FAILS AND THE GENERATOR FAILS TO START AND
RUN) THE EXERCISER MUST BE RESET AFTER THE
POWER IS RESTORED.
This completes your installation and unit testing.
ALWAYS leave the system in automatic mode unless
servicing the unit. For automatic operation, the right hand
toggle switch on the generator control panel must be left
in the “NORMAL” position.
