Section 3 - Operation

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.

3.2CONTROL CONSOLE

COMPONENTS

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

3.1USING AN ENGINEERED “GTS”

TRANSFER SWITCH

Figure 3.1 - Home Standby Generator Panel

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.

5 FLASHING RED LED'S = EXERCISER NOT SET

(IN AUTO MODE ONLY) SOLID GREEN LED = SYSTEM READY, UTILITY POWER ON RED LED'S = INDIVIDUAL FAULT

•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 (Included switch)

•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.

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.

3.2.2 FAULT INDICATOR LEDS

These LEDs turn ON when one of the following engine faults occurs and the 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.
