How to troubleshoot no display and no output signals on Endress+Hauser Measuring Instruments?
- R
  Rebecca SchultzSep 8, 2025
  If your Endress+Hauser Measuring Instruments display is not visible and there are no output signals, first, check the supply voltage at terminals 1 and 2. Then, inspect the power line fuse. For 85 to 260 V AC, it should be a 0.8 A slow-blow / 250 V fuse. For 20 to 55 V AC / 16 to 62 V DC, it should be a 2 A slow-blow / 250 V fuse. If these steps don't resolve the issue, the measuring electronics may be defective, and you may need to order spare parts.

  If your Endress+Hauser Measuring Instruments has no visible display but the output signals are present, first, check if the ribbon-cable connector of the display module is correctly plugged into the amplifier board. If it is, the display module may be defective, requiring you to order spare parts. Alternatively, the measuring electronics could be defective, also requiring you to order spare parts.
