Problem description

Corrective action

Failure of the display. After selecting any key, the whole display remains dark or the display is defective.

Check the following issues:

  • Is the supply voltage connected? This is the case when the System-LED is illuminated.
  • Is the environmental temperature within the allowed range?
  • Try to adjust the contrast of the display by using PowerPort-E (increase/ decrease).

If these checks do not show any results, send the relay back to the manufacturer.

Failure of a relay output.

(Also refer to: ”relay outputs do not react“).

The physical status does not match the reported state. Check the reported state of the relay output with the HMI or PowerPort-E.

Check the following issues:

  • Is the relay output in the latched state? Acknowledge the state if necessary.
  • Is <Inverting> parameter of the relay output set?
  • Check the wiring.
  • Unplug the wiring from the relay output and measure its output. Set the state of the relay output by using the test functions.

Force/Disarm.

If these checks do not show any results, send the relay back to the manufacturer.

Failure of a digital input. The physical status of a digital input does not match its reported state. Check the reported state of the digital input with the HMI or PowerPort-E.

Check the following issues:

  • Is the configured voltage level set correctly?
  • Is the voltage level of the digital input (signal level) correct?
  • Is the parameter <Inverting> set?
  • Check the wiring.

If these checks do not show any results, send the relay back to the manufacturer.

Wrong setting of the device´s clock after a shortage of the supply voltage. The internal battery for powering the clock is empty or defect. The relay is also working properly with an empty clock battery. The device´s time can be synchronized. Please contact the service team.
Failure of a key.   Send the relay back to the manufacturer.
