Possible Causes

Controller in OFF or MANUAL mode instead of AUTO, Disabled auto‑start setting, Faulty ATS start signal contacts, Broken remote start wiring

How to Fix / Troubleshooting

Safety first: Ensure the generator is safe to run and that automatic starting will not endanger personnel working on the system.

  • Check controller mode: Verify the Genergy controller is set to AUTO. If in OFF or MANUAL, switch to AUTO.
  • Review auto‑start settings: In the controller menu, confirm that automatic start on mains failure is enabled and that delay timers are set appropriately.
  • Test ATS start signal: Simulate a mains failure and measure the start signal at the generator control terminals. If no signal is present, inspect ATS auxiliary contacts and wiring.
  • Repair wiring: Replace damaged remote start cables and tighten terminal screws.
