2.6 ENGINE GOVERNOR
ADJUSTMENT
If both AC frequency and voltage are correspondingly high or low,
adjust the engine governor as follows:
The engine must be OFF to perform steps 1

and 2.
1. Loosen the governor clamp bolt (Figure 2.1).
2. Hold the governor lever at its wide open throttle position
(clockwise), and rotate the governor shaft clockwise as far
as it will go. Then, tighten the governor lever clamp bolt to 70
inch-pounds (8 N-m).
3. Start the generator; let it stabilize and warm up at no-load.
4. Connect a frequency meter across the generators AC output
leads.
5. Turn the adjust screw to obtain a frequency reading of 62.5
Hz.

CONTROL PANEL INTERFACE

3.1.1 USING THE AUTO/OFF/MANUAL SWITCH
(FIGURE 3.1)
With the switch set to AUTO, the engine may

crank and start at any time without warning.
Such automatic starting occurs when utility
power source voltage droops 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 switch
to OFF and remove the fuses before work-
ing on or around the generator or transfer
switch. Then, place a "DO NOT OPERATE"
tag on the generator panel and on the trans-
fer switch.
1. "AUTO" Position – Selecting this switch activates fully auto-
matic system operation. It also allows the unit to automatically
start and exercise the engine every seven days with the setting
of the exercise timer (see the Setting the Exercise Timer sec-
tion).
2. "OFF" Position – This switch position shuts down the engine.
This position also prevents automatic operation.
3. "MANUAL" Position – Set the switch to MANUAL to crank
and start the engine. Transfer to standby power will not occur
unless there is a utility failure.
3.1.2 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.
A switch on the control panel (see Figure 3.1) 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 gen-
erator 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.
