Section 3 - Operation

QUIETSOURCE™ Liquid-cooled 30 kW Generators

•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.

3.2CONTROL 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.

DANGER

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)

SET EXECISER TIME SWITCH

LED INDICATORS:

FLASHING GREEN LED = NO UTILITY SENSE

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

‹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.
