Manual Transfer START-UP Automatic Operation

Section 3 - Operation

Bryant Liquid-cooled 15 kW Generators

3.1.2 FAULT INDICATOR LAMP

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

•	Low oil pressure	•	Overcrank
•	High coolant temperature	•	Overspeed

•Low coolant level

3.1.3 15 AMP FUSE

The 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 replacement of the fuse is necessary, use only an identical 15-amp fuse. (Type AGC, part number 022676).

3.1.4 7.5 AMP INLINE FUSE

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.

NOTE:

This fuse will not remove the positive (+) battery input power from the PCB when it opens. This means the exercise timer will not be reset. If this fuse does open, carefully check the wiring to the start, fuel, field boost and transfer outputs before replacing the fuse.

3.1.5 SET EXERCISE TIME SWITCH

This switch allows for programming the generator to start and exercise automatically. See “Weekly Exercise Cycle” (Section 3.5).

3.2MANUAL TRANSFER AND

START-UP

To transfer electrical loads to the STANDBY (GEN- ERATOR) power source side and start the engine manually, refer to the Owner’s Manual of the particu- lar transfer switch.

3.3AUTOMATIC OPERATION

To set the system for fully automatic operation, pro- ceed as follows:

•Check that load circuits are connected to the utility power supply.

•Set the AUTO/OFF/MANUAL switch to its AUTO position.

•Set the generator main circuit breaker to its ON or CLOSED position.

3.4WEEKLY EXERCISE CYCLE

The generator will start and exercise once every seven days. During this weekly exercise, the unit runs for about 20 minutes and shuts down. Transfer of loads to generator output does not occur during the exer- cise.

To select day and time for exercising, proceed as follows:

•Set the AUTO/OFF/MANUAL switch to OFF.

•Set generator main circuit breaker to OFF or OPEN.

•Locate the rocker switch on the control panel iden- tified with the words “Set Exercise Time” (Figure 3.2).

•Push “Set Exercise Time” switch to ON position for 20 to 30 seconds and then release. Switch will spring back into its original position when released.

•Wait 30 seconds before setting the AUTO/OFF/ MANUAL switch to AUTO position.

If the AUTO/OFF/MANUAL switch is switched

!too soon, the engine may start. If engine does start, it will shut down automatically in about two (2) minutes.

•Set the generator main circuit breaker to its ON or CLOSED position.

•Generator is now programmed to start and exer- cise every seven days thereafter, on day and time of day the switch was actuated.

•Place a sign on the generator control panel and the transfer switch, indicating the day and time the generator will be exercising.

NOTE:

If battery terminals are disconnected, the exercise timer needs to be reset for correct automatic exer- cise operation.
