Generator fails to perform its scheduled weekly exercise run; no codes are displayed.

Safety first: Ensure the generator is in AUTO mode and that utility power is present before programming.

• Check controller settings: Access the All Power America controller menu and verify the current time, date, and exercise schedule. Correct any errors.
• Enable exercise: Confirm that the exercise function is turned ON and set to the desired day and time.
• Manual test: Start the generator manually to confirm it can run. If manual start works but exercise does not, the controller's scheduler may be faulty.
• Controller replacement: Replace the control board if the internal clock or scheduler cannot be corrected.
