What to do if Endress+Hauser Cubemass DCI Measuring Instruments display is not visible and there are no output signals?
- R
  Robert GriffithAug 4, 2025
  If the display is not visible and there are no output signals, first, check the supply voltage at terminal 1 and 2. Next, check the device fuse. For 81 to 260 V AC, the fuse should be 0.8 A slow-blow / 250 V. For 20 to 55 V AC and 16 to 62 V DC, it should be 2 A slow-blow / 250 V. If these steps don't resolve the issue, the measuring electronics may be defective and require a spare part.

  Christopher MorrisAug 12, 2025
  If the display is not visible but the output signals are present, check whether the ribbon-cable connector of the display module is correctly plugged into the amplifier board. If the connection is correct, the display module may be defective, and you may need to order spare parts. Another possibility is that the measuring electronics are defective, requiring spare parts.
