SWITCH
Use this three-position switch as follows:
• Set the switch to AUTO for fully automatic opera-
tion. See “Automatic Operation” (Section 3.6).
• Set switch to MANUAL position to crank and start
the generator engine.
• Set switch to OFF position to shut down an operat-
ing engine. With OFF selected, operation will not
be possible.

DANGER
With switch set to AUTO, engine can crank and
start suddenly without warning. Such automatic
start up normally occurs when utility source
voltage drops below a pre-set level. To prevent
possible injury that might be caused by such
sudden starts, set AUTO/OFF/MANUAL switch
to OFF before working on or around the unit.
Then, place a “DO NOT OPERATE” tag on control
console.

3.2.2 FAULT INDICATOR LED
This LED goes ON when one or more of the following
engine faults occurs and when engine shuts down.

• Low Oil Pressure
• Overcrank
• Low Battery
• Overspeed/RPM Sensor Loss
• High Coolant Temperature/Low Coolant Level
See Section 1.7 for further explanation of engine pro-

3.2.3 15 AMP FUSE
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 the fuse needs to be replaced,
use only an identical 15-amp replacement fuse. (Type
AGC)

NOTE:
This fuse will not remove the + battery input
power from the PCB when it opens. This means
the exercise timer will not be reset.
