Make sure the generator battery is fully charged, prop-
erly installed and interconnected, and ready for use.
Check to ensure that there are no loose electrical con-
nections. Restrain any loose wires to keep them clear
of any moving generator set components.

3.1 USING AN ENGINEERED “GTS”

TRANSFER SWITCH

When required, the pre-packaged standby generator
can be installed with an engineered “GTS” type auto-
matic transfer switch.
In this application, the GTS is responsible for utility
sensing, weekly exercising, and load transferring.
Position two of the four-position dip switch is used to
turn over this control to the GTS.

Pos2 ON — GTS Application

• The control board will NOT monitor utility.
• The control board will NOT perform a weekly
exercise. (The five red LEDs will not flash in this
mode.)
• 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 — Prepackaged ATS Application

• The control board will perform all of the automatic
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
position.
AUTO — The control board will monitor the two-wire
start circuit. When a two-wire start is sent, 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.
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.

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”.
• 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 "Engine Protective Devices" for further explana-
tion of engine protection functions.
