Automatic Operation Sequence
The generator’s control board monitors utility voltage. If the
utility voltage drops below a preset level, the control board
will signal the engine to crank and start. When the utility
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 the utility source voltage.
• If the utility source voltage dropsbelowapproximately70
percent of the nominal supply voltage, the sensor initiates
a 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 the utility voltage. When the utility
voltage is restoredaboveapproximately80 percent of the
nominal source voltage, a shut-down timer is initiated and the
engine will go to engine cool-down.
Engine Cool-down Timer
When the utility power is sensed, the load transfers to the
utility source and the engine will go into a 5 minute cool down
period.
