• The control board will NOT activate the transfer

output.

• The control board WILL monitor all engine condi-

tions and shut down on all the faults listed in this
document.

Pos2 OFF — ATS Application

• The control board will perform all of the automat-

ic features listed in this document.

• The two-wire start connections should NOT be

used.

GTS Mode Operation

When in GTS mode, the control board will respond
as follows based on the AUTO/OFF/MANUAL switch
position.

OFF — The generator will not start and run in this
position.

MANUAL — The control board will start and run the
generator whenever the switch is in the manual posi-
tion.

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. Whe the two-wire start is removed the control
board will immediately stop the generator.

NOTE:

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.

CONTROL CONSOLE
COMPONENTS

The components of a home standby generator control
console (Figure 3.1) are as follows:

Figure 3.1 - Home Standby Generator Panel

3.2.1 AUTO/OFF/MANUAL SWITCH

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
be possible.

With switch set to AUTO, engine can crank
and start suddenly without warning. Such
automatic start up normally occurs when utili-
ty 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-
tection functions.

3.2.3 15 AMP FUSE

This 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)

3.2.4 4 AMP INLINE FUSE

This fuse protects the battery charger against electri-
cal overload. If the fuse needs to be replaced, use only
an identical 4 amp replacement fuse (type AG).

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.

3.2.5 SET EXERCISE TIME SWITCH

This switch allows programming the generator to
start and exercise automatically. “See Weekly
Exercise Cycle.”
