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 |

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
3.1.1 AC VOLTMETER
The voltmeter displays generator AC output voltage dur- ing operation. Voltage is regulated by a
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
3.1.4 DC VOLTMETER
The generator is equipped with a
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
3.1.11 SET EXERCISE TIME SWITCH
This switch allows to program the generator to start and exercise automatically. (See Section 3.6, page 14)
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.
