3.10 SETTING THE EXERCISE TIMER
3.10.1 6 KW, 8 KW AND 10 KW UNITS (NON-SA)
Your generator is equipped with an exercise timer.
Once it is set, the generator will start and exercise
once every seven days, on the day of the week and at
the time of day you complete the following sequence.
During this exercise period, the unit runs for approx-
imately 12 minutes and then shuts down. Transfer of
loads to the generator output does not occur during
the exercise cycle.
A switch on the control panel (see Figure 2.1, Page
18) allows you to select the day and time for system
exercise. To select the desired day and time of day,
proceed as follows:
1. Verify that the Auto/Off/Manual switch is set
to AUTO.
2. Hold down the Set Exercise Timer switch until
the generator starts (approximately 10 seconds)
and then release.
3. The generator will start and run for approximate-
ly 12 minutes and then shut down on its own.
The exerciser will then be set to run at that time
of day every week.
NOTE:
The exerciser will only work in the AUTO mode
and will not work unless this procedure is per-
formed. The exerciser will need to be reset every
time the 12-volt battery is disconnected and then
reconnected. The exerciser WILL NOT work if dip
switch 2 (Remote Not Auto) is ON.
3.10.2 SOUND ATTENUATED UNITS
The generator will start and exercise once every
seven days. During this weekly exercise, the unit
runs for about 20 minutes and shuts down.
Transfer of loads to generator output does not occur
during the exercise.
A switch on the control panel (see Figure 2.2, Page
18) permits the day and time of day for system exer-
cise to be selected. To select the desired day and time
of day, proceed as follows:
1. Set the Auto/Off/Manual switch to OFF.
2. Set the generator’s main circuit breaker to its
OFF (or open) position.
3. On the control panel, locate the rocker switch
identified with the words “Set Exercise Time.”
4. Hold the “Set Exercise Time” switch in the ON
(downward) position for 20 to 30 seconds. The
switch springs back into its original position
when released.
5. Wait about 30 seconds before setting the
Auto/Off/Manual switch to AUTO.
If you reset the Auto/Off/Manual switch too
soon, the engine may start. If engine does
start, it shuts off automatically in two minutes.
6. Set the generator’s main circuit breaker to
its ON (or closed) position. The generator will
start and exercise every seven days thereafter,
on the day and at the time of day you pressed
the switch.
