Troubleshooting - Generac Power Systems PWRcell Reference Manual

Generator/PWRcell Inverter Test with
Switch Enabled (perform if Lockout Switch
Enabled on any loads)
1. Enable Islanding and verify load shed settings.
2. Simulate a utility loss by turning MLCB (service
disconnect) to OFF.
3. All modules will lose power and LEDs will disable.
4. Generator should power on after preset delay.
Inverter will transfer to Island mode.
NOTE: The inverter will lower it's frequency output for
approximately one second at one minute intervals to
maintain the SMM lockout setting.
NOTE: For modules with lockout switch enabled, LEDs
will flash at six second intervals and load will remain
disabled while in generator/inverter power.
Return to Utility Test
1. Return utility power by setting the MLCB (service
disconnect) to ON.
NOTE: All modules should begin flashing at one second
intervals. All modules will recover in five minutes
(including units with lockout switch enabled).
