What does 'Need RTU Start or Stopped' message mean on Ampcontrol IPD?
If an Ampcontrol Relay shows 'Need RTU Start or Stopped - RTU or Stopped - RTU PTC', the relay is waiting for the RTU digital inputs to be closed. Ensure all three RTU digital inputs are closed.
What to do if Ampcontrol Relay remote display is blank but RDM Healthy LED flashes?
If the remote display of your Ampcontrol Relay is blank and the RDM Healthy LED flashes at 1 Hz, it means power to the RDM is healthy, but there's no data. Check the data connection between the relay and the RDM.
