QUIETSOURCELiquid-cooled 30 kW Generators

‹ 2.11.7 ELECTRICAL SYSTEM

NOTE:

Make sure the generator is properly connected to an approved earth ground and/or ground rod.

Make sure the generator battery is fully charged, properly 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.

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.

3.2CONTROL CONSOLE

COMPONENTS

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

3.1USING A STANDARD “GTS”

TRANSFER SWITCH

Figure 3.1 - Home Standby Generator Panel

When required, the pre-packaged standby generator can be installed with an engineered Generac “GTS” type automatic 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 exer-

cise. (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 — 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.

‹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.

DANGER

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- trol console.
