15 Amp Fuse
The generator’s 15 Amp fuse is critical to correct system
operation. The 15 Amp fuse was removed at the factory to
prevent the unit from starting during shipping. Your installer
will ensure the fuse is properly installed upon completion of
the installation.
Automatic Operation
To select automatic operation, do the following:
1. Confirm 15 Amp fuse is installed in control panel.
2. Set the main distribution panel circuit breaker that
sends utility voltage to the transfer switch to
ON
.
3. Set the generator’s circuit breaker to its
ON
position.
4. Set the control panel system switch to
AUTO
.
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.
When utility voltage is lost and the sensor has timed
out, the engine will crank and start. 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 utility power after a 5 minute minimum run time and
utility power is available.
4. The generator will run for an additional one minute for
engine cool down, then shut down.
If utility power 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 residential generator will now start automatically and
will supply power to the transfer switch when utility power
is lost.
Setting Exercise Timer
The residential generator 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 during the cycle).
A button on the control panel is labeled “SET EXERCISE”
(see
System Control Panel
). The specific day and the
specific time of day this button is pressed is programmed
into the control board memory. This date and time is then
used to automatically initiate the system exercise cycle. The
“SET EXERCISE” legend on the control panel will flash until
the set exercise cycle is set.
To perform the Set Exercise procedure:
1. Choose the day and time you want your residential
generator to exercise.
2. On that day and time, press and hold down
“SET EXERCISE” for three seconds.
“SET EXERCISE” will flash until the button is pressed
for three seconds, then “SET EXERCISE” will illuminate
for 5 seconds, and finally turn off. The SET EXERCISE
date and time are now ‘locked-in’ (registered in
system memory).
3. Certain models will immediately start and run their
20 minute exercise cycle. Other models will initiate
the 20 minute exercise cycle seven days after the
SET EXERCISE date and time is ‘locked-in’.
For example, if you press SET EXERCISE on Sunday morning
at 10:00 AM, the unit is set to run an exercise cycle every
Sunday at 10:00 AM (+/- 1/2 hour).
“Set Exercise” will only work if the unit is in the
AUTO
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 starting 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.
CAUTION
With the system switch set to
AUTO
,
the engine may crank and start at any time
without warning.
To prevent possible injury that may be caused by such
•
sudden starts, always set the system switch to
OFF
if
performing maintenance on the system.
Remove the 15 Amp fuse before working on or around
•
the generator or transfer switch.
