Automatic weekly exercise test does not run even though the generator works in manual mode.

Safety first: Ensure the generator is in a safe state and not needed for immediate backup while adjusting settings.

• Verify AUTO mode: Confirm the WEN controller is set to AUTO, not OFF or MANUAL.
• Check date and time: Enter the controller menu and set the correct date and time. An incorrect clock can prevent the exercise from running.
• Review exercise settings: Ensure the exercise function is enabled and scheduled for the desired day and time. Save settings properly.
• Simulate exercise: Some controllers allow a manual exercise start. Use this to confirm the function works.
• Controller replacement: If settings are correct but the exercise never runs, the internal timer circuit may be faulty and the control board may need replacement.
