Guardian Technologies 004988-4 Control Console Components, ‹ 3.2.1 AUTO/OFF/MANUAL Switch

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 control board will immediately start and run the gen- erator. 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:

‹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.

Section 3 - Operation

Liquid-cooled 30 kW Generators

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 Section 1.7 for further explanation of engine pro- tection functions.

‹3.2.3 15 AMP FUSE

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)

‹3.2.4 4.0 AMP INLINE FUSE

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

(SEE OWNER'S MANUAL FOR COMPLETE LED DETAILS)

TIME

1) PLACE AUTO/OFF/MANUAL SWITCH TO AUTO POSITION.

0E7194

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.

‹3.2.5 SET EXERCISE TIME SWITCH

This switch allows programming the generator to start and exercise automatically. “See Weekly Exercise Cycle.”

‹3.2.6 SYSTEM READY LED

The System Ready LED (green) has two main pro- poses. First, the LED will be ON when the AUTO/ OFF/MANUAL switch is in the AUTO position, utility is present, and there are no system alarms. This ON state indicates the system is fully ready for automatic operation.
