Operation

To select automatic operation, do the following:
1. Set the service disconnect or main distribution panel
circuit breaker that sends utility voltage to the transfer
switch to ON.
2. Set the generator's main circuit breaker to its ON
position.
3. Set the system switch to AUTO.
CAUTION
With the switch set to AUTO, the engine may
crank and start at any time without warning. Such
automatic starting normally occurs when utility
source voltage drops below a preset level or
during the normal exercise cycle.
• To prevent possible injury that might be caused by such sudden
starts, always set the system switch to OFF.
• Remove the 15 Amp fuse before working on or around the
generator or transfer switch.

Checking Automatic Operation

To check the system for proper automatic operation, proceed
as follows:
1. Turn OFF the service disconnect or main distribution
panel circuit breaker sending power to the automatic
transfer switch.
The engine will crank and start when the utility voltage drops
out and the sensor has timed out. Let the system go through
its entire automatic operation sequence.
2. With the generator output supplying its loads, turn ON
the service disconnect or main distribution panel circuit
breaker that supplies utility power to the Automatic
Transfer Switch.
3. The automatic transfer switch will transfer loads back
to the utility power after 5 minute minimum run time
and utility is restored.
4. The generator will run for an additional one minute for
engine cool down, then shut down.
NOTE: If utility is restored and generator does not shut down
after 10 minutes, set system switch to OFF and contact your
installer or local service center.
This completes the test procedures for automatic operation.
The Home Generator System will now start automatically
when utility power is lost and will supply power to the
transfer switch.

Servicing the System

To service system:
1. Set the system switch to OFF.
2. Set the generator's main circuit breaker to its OFF
position.
3. Utility voltage is present. Disconnect power before
servicing by removing the two 2 Amp fuses from the
transfer switch.

Setting Exercise Timer

The Home Generator System is equipped with an exercise
timer that will start and exercise the system once every
seven days. During this exercise period, the unit runs for
approximately 20 minutes and then shuts down. Electrical
load transfer DOES NOT occur during the exercise cycle
(unless an utility power outage occurs).
A switch on the control panel is labeled "Set Exercise" (see
page 11). The specific day and the specific time of day this
switch is pressed is programmed into the control board
memory. This date and time is then used to automatically
initiate the system exercise cycle. The LED on the control
panel will flash until the set exercise is set.
To perform the Set Exercise procedure:
1. Choose the day and time you want your Home
Generator System to exercise.
2. On that day and time, press and hold down the "Set
Exercise" switch for three seconds.
NOTE: The LED will flash until the switch is pressed for three
seconds, then the LED will illuminate for 5 seconds and turn
off.
For example, if you press the "Set Exercise" switch on
Sunday morning at 10:00 AM, the unit will run an exercise
cycle the following Sunday at 10:00 AM (+/- 1/2 hour).
NOTE: "Set Exercise" will only work if the unit is in the
Automatic mode and this exact procedure is followed. The
exerciser will need to be re-set if the 15 Amp fuse is
removed or changed, or if the 12 Volt DC battery is
disconnected.
If you want to change the day and time the unit exercises,
simply perform the "Set Exercise" procedure at the exact
weekday and time you want it to take place.
