‹3.1.7 FAULT INDICATOR LAMP

This lamp goes ON when one or more of the following engine faults occurs and when engine shuts down.

•

Low oil pressure

•

High coolant temperature

•

Low coolant level

•

Overcrank

•Overspeed

‹3.1.8 15-AMP FUSE

This fuse protects the control console’s DC control cir- cuit against electrical overload. If the fuse has melted open because of an overload, engine cranking and start- up cannot occur. Replace the fuse with an identical AGC 15-amp replacement fuse.

‹3.1.1 AC VOLTMETER

The voltmeter displays generator AC output voltage dur- ing operation. Voltage is regulated by a solid-state volt- age regulator and is proportional to AC frequency. Refer to the unit’s DATA PLATE for rated AC voltage.

‹3.1.2 AC AMMETER

This indicates current draw of connected electrical loads during operation. DO NOT EXCEED THE UNIT’S RATED MAXIMUM CONTINUOUS CURRENT. Refer to the unit DATA PLATE.

‹3.1.3 AC FREQUENCY METER

This indicates generator AC output frequency in Hertz (cycles per second). Frequency is proportional to engine speed. Units with a four-pole rotor, supply 60 Hertz at 1,800 rpm. The frequency reading with no electrical loads connected (no-load condition) should be between 60-62 Hertz.

‹3.1.4 DC VOLTMETER

The generator is equipped with a belt-driven DC alter- nator, which maintains battery state of charge when the engine operates. The control module assembly (CMA) also incorporates a trickle charge circuit that maintains battery state of charge during nonoperating periods. Battery voltage should read approximately12.5 to 14.5 volts DC. A low battery voltage indicates the battery is discharging.

‹3.1.9 7.5 AMP INLINE FUSE (NOT SHOWN)

This inline fuse is connected in the 15A line that runs between the Auto/Off/Manual switch and position 10 of the 76009A PCB. This fuse protects the start, fuel, field boost, and transfer outputs from the PCB and will open if there is excessive current draw on any one of these outputs.

‹3.1.10 VOLTAGE-PHASE SELECTOR SWITCH

This switch permits selection between either line-to-line or line-to-neutral voltage and amperage readings on the console AC voltmeter and AC ammeter.

‹3.1.11 SET EXERCISE TIME SWITCH

This switch allows to program the generator to start and exercise automatically. (See Section 3.6)

3.2USING THE AUTO/OFF/MANUAL SWITCH

‹3.2.1 “AUTO” POSITION

Selecting this switch position activates fully automatic system operation. It also allows the unit to start and exercise the engine every seven days with the setting of the exercise timer.

‹3.1.5 HOURMETER

This indicates the time the engine-generator has operat- ed, in hours and tenths of hours. Use the hourmeter along with the periodic maintenance schedule for your generator set.
