Why is the HMI on my E-Series Relay dark?

Press any of the keys on the faceplate of the relay.  If the HMI remains dark, please check the following issues.

  • Is the supply voltage connected? (Is the Operational LED on?)
  • Is the environmental temperature within the allowed range?
  • Try to adjust the contrast of the display by using PowerPort-E (increase/decrease).
If the problem persists, contact our support team.  What is the technical support number for Meters and Relays?
