Possible Causes

Incorrect date/time or schedule settings, disabled exercise mode, controller firmware glitch, weak internal backup battery (if equipped)

How to Fix / Troubleshooting

Safety first: Ensure the generator is in a safe state. Controller can remain powered for programming.

  • Verify date and time: Enter the controller setup menu and confirm the current date and time are correct.
  • Check exercise settings: Ensure the exercise function is enabled and scheduled for the desired day and time. Save changes.
  • Test exercise manually: Use the controller's test function to initiate an exercise run and confirm operation.
  • Power cycle controller: If settings appear correct but exercise still does not run, power-cycle the controller by disconnecting the battery for several minutes, then reprogram.
