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:

Setting Exercise Timer

The 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).
