pre-set value, transfer switch circuits signal the

transfer switch main contacts to actuate to the

“Standby” power source side. Generator AC output

then powers load circuits.

• When the utility power source voltage is restored

above a pre-set level, transfer switch circuits signal

the switch main contacts to move back to their util-

ity power source side.

• Following re-transfer back to the utility power

source side, transfer switch circuit board action

signals the generator to stop. Engine then shuts

down.

When in GTS mode, the control board will respond as follows based on the generator 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 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.

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.

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.

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 3.6).

•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.
