AUTO-OFF-MANUAL SWITCH:
Use this switch to (a) select fully automatic operation,
(b) to crank and start the engine manually, and (c) to
shut the unit down or to prevent automatic startup.
1. AUTO position:
a. Select AUTO for fully automatic operation.
b. When AUTO is selected, circuit board will moni-
tor utility power source voltage.
c. Should utility voltage drop below a preset level
and remain at such a low level for a preset time,
circuit board action will initiate engine cranking
and startup.
d. Following engine startup, circuit board action
will initiate transfer of electrical loads to the
“Standby” source side.
e. On restoration of utility source voltage above
a preset level, circuit board action will initiate
retransfer back to the “Utility Source” side.
f. Following retransfer, circuit board will shut the
engine down and will then continue to monitor
utility source voltage.
2. OFF Position:
a. Set the switch to OFF to stop an operating engine.
b. To prevent an automatic startup from occurring,
set the switch to OFF.
3. MANUAL Position:
a. Set switch to MANUAL to crank and start unit
manually.
b. Engine will crank cyclically and start (same as
automatic startup, but without transfer). The unit
will transfer if utility voltage is not available.

7.5 AMP FUSE:
This fuse protects the DC control circuit (including the
circuit board) against overload. If the fuse element
has melted open due to an overload, engine cranking
or running will not be possible. Should fuse replace-
ment become necessary, use only an identical 7.5
amp replacement fuse.
SETTING THE EXERCISE TIMER:
This generator is equipped with an exercise timer.
Once it is set, the generator will start and exercise
every seven days, on the day of the week and at the
time of day specified. During this exercise period,
the unit runs for approximately 12 minutes and then
shuts down. Transfer of loads to the generator output
does not occur during the exercise cycle unless utility
power is lost.
8kW:
A switch on the control panel (see Figure1) permits
selection of the day and time for the system to exercise.
At the chosen time, perform the following sequence to
select the desired day and time of day the system will
exercise. Remember seasonal time changes affect the
exercise settings.
1. Verify that the AUTO-OFF-MANUAL switch is set to AUTO.
2. Press and hold the “Set Exercise” switch for several
seconds. All the red LED’s will stop flashing immediately
and the generator will start.
3. The generator will start and run for approximately 12
minutes and then shut down. The exerciser is now set to
run at this time of day each week.
Example: If the “Set Exercise” pressed on Saturday
afternoon at 2:00 p.m., the generator will start and
exercise for approximately 12 minutes every Saturday
at 2:00 p.m.
note: the exerciser will only work in the auto
mode and will not work unless this procedure
is performed. the exerciser will need to be reset
every time the 12 Volt battery is disconnected and
then reconnected, and when the fuse is removed
and/or replaced.
