Briggs & Stratton 45000 Controls, Automatic Operation Sequence, Setting Exercise Timer

Controls

See the Operator’s Manual for complete description of the home generator controls.

Operation

Automatic Operation Sequence

The generator’s control panel houses a logic control circuit board. This control board constantly monitors utility power source voltage. Should that voltage drop below a preset level, control board action will signal the engine to crank and start.

When utility source voltage is restored above a preset voltage level, the engine is signaled to shut down.

The actual system operation is not adjustable and is sequenced by sensors and timers on the control board, as follows:

Utility Voltage Dropout Sensor

•This sensor monitors utility source voltage.

•If utility source voltage drops below about 70 percent of the nominal supply voltage, the sensor energizes a 10 second timer. The timer is used to ‘sense’ brown- outs.

•Once the timer has expired, the engine will crank and start.

Utility Voltage Pickup Sensor

This sensor monitors utility power supply voltage. When that voltage is restored above 80 percent of the nominal source voltage, a time delay starts timing and the engine will go to engine cool-down.

Engine Cool-down Timer

•When the load is transferred back to the utility power source, the engine cool-down timer starts timing.

•The timer will run for about one minute, then the generator will stop.

•Minimum engine run time is 5 minutes.

Setting Exercise Timer

The home generator is equipped with an exercise timer that will start and exercise the system once every seven days. During this exercise period, the unit runs for approximately 20 minutes and then shuts down. Electrical load transfer DOES NOT occur during the exercise cycle (unless an utility power outage occurs).

A button on the control panel is labeled “Set Exercise” (see System Control Panel). The specific day and the specific time of day this button is pressed is programmed into the control board memory. This date and time is then used to automatically initiate the system exercise cycle. The “SET EXERCISE” legend on the control panel will flash until the set exercise cycle is set.

To perform the Set Exercise procedure:

1.Choose the day and time you want your home generator to exercise.

2.On that day and time, press and hold down the “Set Exercise” button for three seconds.

NOTE: “SET EXERCISE” will flash until the button is pressed for three seconds, then “SET EXERCISE” will illuminate for 5 seconds, and finally turn off.

3.The unit will then start and run it’s 20 minute exercise cycle.

For example, if you press the “Set Exercise” button on Sunday morning at 10:00 AM, the unit will run an immediate exercise cycle and an exercise cycle every following Sunday at 10:00 AM (+/- 1/2 hour).

NOTE: “Set Exercise” will only work if the unit is in the Automatic mode and this exact procedure is followed. The exerciser will need to be re-set if the 15 Amp fuse is removed or changed, or if the 12 Volt DC battery is disconnected.

If you want to change the day and time the unit exercises, simply perform the “Set Exercise” procedure at the exact weekday and time you want it to take place.

Installation Inspection

Complete the ”Installation Checklist” as you make the inspection. Ensure all items have been filled-in and all signatures have been obtained. Mail the white copy (and emissions statement, if completed) to:
