OFF — The generator will not start and run in this
MANUAL — The control board will start and run the
generator whenever the switch is in the manual posi-
AUTO — The control board will monitor the two-wire
start circuit. When a two-wire start is issued, the con-
trol board will immediately start and run the genera-
tor. When the two-wire start is removed the control
board will immediately stop the generator.
If the generator is installed in conjunction with an
engineered GTS type transfer switch, refer to the
applicable transfer switch manual for exact oper-
ating parameters and timing sequences.
For proper battery charger operation, it will be nec-
essary to supply a fused 240VAC utility fed supply to
terminals N1 and N2 in the control panel.
The components of a home standby generator control
console (Figure 3.1) are as follows:

Use this three-position switch as follows:
• Set the switch to AUTO for fully automatic opera-
tion. See "Automatic Operation" (Section 3.5).
• Set switch to MANUAL position to crank and start
the generator engine.
• Set switch to OFF position to shut down an oper-
ating engine. With OFF selected, operation will not

With switch set to AUTO, engine can crank and
start suddenly without warning. Such automat-
ic 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 con-
3.2.2 FAULT INDICATOR LEDS
(SEE CHART ON PAGE 14)
These LEDs turn ON when one or more of the follow-
ing engine faults occurs and the engine shuts down.
• Low Oil Pressure
• Low Battery
• Overspeed/Engine Speed Signal Fault
• High Coolant Temperature/Low Coolant Level

3.2.3 15 AMP FUSE
This fuse protects the control console's DC control
circuit against electrical overload and is located
inside the control panel. 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
3.2.4 5 AMP FUSE
This fuse protects the battery charger against electri-
cal overload and is located inside the control panel. If
the fuse needs to be replaced, use only an identical 5-
amp replacement fuse (type ATO).
This fuse will not remove the + battery input
power from the PCB when it opens. This means
the exercise timer will not be reset.
3.2.5 SET EXERCISE TIME SWITCH
This switch allows programming the generator to
start and exercise automatically. "See Weekly
