Section 3 - Operation

Guardian Liquid-cooled 25 kW Generator

GTS Mode Operation

When in GTS mode, the control board will respond as follows based on the generator AUTO/OFF/MANU- AL 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.

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.

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 LEDS

(SEE CHART ON PAGE 14)

These LEDs turn ON when one or more of the follow- ing engine faults occurs and the engine shuts down.

•Low Oil Pressure

•Overcrank

•Low Battery

•Overspeed/Engine Speed Signal Fault

•High Coolant Temperature/Low Coolant Level

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

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

‹3.2.3 15 AMP FUSE

This fuse protects the control console’s DC control circuit against electrical overload and is located inside the control panel. 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 ATO).

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

2)HOLD "SET EXERCISE TIME" SWITCH IN "ON" POSITION FOR

THREE SECONDS AND RELEASE. THE EXERCISER IS NOW SET. ALL FIVE RED LED'S WILL FLASH FOR

10 SECONDS. THEN THE UNIT WILL START, RUN THROUGH THE EXERCISE CYCLE AND SHUTDOWN.

‹3.2.4 5 AMP FUSE

This fuse protects the battery charger against electri- cal overload and is located inside the control panel. If the fuse needs to be replaced, use only an identical 5- amp replacement fuse (type ATO).

NOTE:

power from the PCB when it opens. This means the exercise timer will not be reset.

‹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.

‹3.2.5 SET EXERCISE TIME SWITCH

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