What does it mean if '8Err78' appears with a lit LED 'd' on ZIEHL UFR1001E?

  If '8Err78' appears on the display of your ZIEHL Relays and the LED 'd' of the faulty output circuit is lit, it indicates an issue with the feedback contacts. If feedback contacts are not connected, set 'trel.8' to 'off'. If they are connected, check the connection. Also, adjust the turn-on time of the section switch under 'trel.8'. Perform a reset by interrupting the control supply voltage for more than 5 seconds.

Why are implausible voltage values displayed on ZIEHL Relays?

  Jason MillerAug 26, 2025
  If you are getting implausible voltage values on your ZIEHL Relays, it might be because 'Pr' is selected with 'N', but 'N' is not connected. To fix this, either select 'Pr' without 'N' or connect 'N'.

What to do if '8Err88' appears on the display of ZIEHL Relays?

  Sergio MitchellAug 25, 2025
  If '8Err88' appears on the display of your ZIEHL Relays, it indicates a hysteresis error due to overlapping release points. To resolve this, ensure that the upper threshold value is set higher than the lower threshold value. Check and adjust the threshold values accordingly.
