Possible Causes

ATS not signaling return of utility, Stuck ATS contactor, Faulty stop control circuit, Controller configuration error

How to Fix / Troubleshooting

Safety first: Ensure that both utility and generator sources are properly coordinated to avoid backfeeding. Only qualified personnel should operate the ATS manually.

  • Verify utility presence: Confirm that utility power is stable at the ATS.
  • Check ATS indicators: Ensure the ATS recognizes utility as available and has transferred load back to utility.
  • Inspect stop control wiring: Verify continuity of the stop signal wiring between ATS and generator controller.
  • Controller settings: Confirm that cool-down and stop parameters are correctly set in the A-iPower controller.
