How to Fix / Troubleshooting

Safety first: Be aware that the generator may start automatically during testing. Keep clear of moving parts.

  • Check controller mode: Ensure the A-iPower controller is set to AUTO, not OFF or MANUAL.
  • Inspect ATS control wiring: Verify that the start/stop control wires between the ATS and generator are intact and properly landed.
  • Simulate outage: With a qualified electrician, simulate a utility outage at the ATS and observe whether a start signal is sent.
  • Clear stored faults: Some controllers inhibit auto-start until previous faults are acknowledged and cleared.
