Power fail message
Whenever the AC power line voltage dips below the minimum specified, this message is
displayed and the generator’s microprocessor is halted.
If you see this message during normal operation, it probably indicates that a power sag or
short duration drop-out has occurred. To clear this condition, cycle the power going to the
generator. If the power is good, the generator should resume normal operation. If you still

the power inlet) is set correctly for the power being fed into the generator.
