3.1.2 FAULT INDICATOR LAMP
The lamp goes ON when one or more of the following
engine faults occurs and when engine shuts down.
• Low oil pressure • Overcrank
• High coolant temperature • Overspeed
• Low coolant level
3.1.3 15 AMP FUSE
The fuse protects the control console’s DC control
circuit against electrical overload. If the fuse has
melted open because of an overload, engine cranking
and startup cannot occur. If replacement of the fuse
is necessary, use only an identical 15-amp fuse. (Type
AGC, part number 022676).
3.1.4 7.5 AMP INLINE FUSE
This inline fuse is connected in the 15A line that runs
between the AUTO/OFF/MANUAL switch and position
10 of the 76009A PCB. This fuse protects the start,
fuel, field boost, and transfer outputs from the PCB
and will open if there is excessive current draw on
any one of these outputs.
NOTE:
This fuse will not remove the positive (+) battery
input power from the PCB when it opens. This
means the exercise timer will not be reset. If this
fuse does open, carefully check the wiring to the
start, fuel, field boost and transfer outputs before
replacing the fuse.
3.1.5 SET EXERCISE TIME SWITCH
This switch allows for programming the generator to
start and exercise automatically. See “Weekly
Exercise Cycle” (Section 3.5).
3.2 MANUAL TRANSFER AND
START-UP
To transfer electrical loads to the STANDBY (GEN-
ERATOR) power source side and start the engine
manually, refer to the Owner’s Manual of the particu-
lar transfer switch.
3.3 AUTOMATIC OPERATION
To set the system for fully automatic operation, pro-
ceed as follows:
• Check that load circuits are connected to the
utility power supply.
• Set the AUTO/OFF/MANUAL switch to its AUTO
position.
• Set the generator main circuit breaker to its ON or
CLOSED position.
3.4 WEEKLY EXERCISE CYCLE
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 exer-
cise.
To select day and time for exercising, proceed as
follows:
• Set the AUTO/OFF/MANUAL switch to OFF.
• Set generator main circuit breaker to OFF or
OPEN.
• Locate the rocker switch on the control panel iden-
tified with the words “Set Exercise Time” (Figure
3.2).
• Push “Set Exercise Time” switch to ON position for
20 to 30 seconds and then release. Switch will
spring back into its original position when
released.
• Wait 30 seconds before setting the AUTO/OFF/
MANUAL switch to AUTO position.
If the AUTO/OFF/MANUAL switch is switched
too soon, the engine may start. If engine does
start, it will shut down automatically in about
two (2) minutes.
• Set the generator main circuit breaker to its ON or
CLOSED position.
• Generator is now programmed to start and exer-
cise every seven days thereafter, on day and time of
day the switch was actuated.
• Place a sign on the generator control panel and the
transfer switch, indicating the day and time the
generator will be exercising.
NOTE:
If battery terminals are disconnected, the exercise
timer needs to be reset for correct automatic exer-
cise operation.
