How to troubleshoot no display and no output signals on Endress+Hauser Measuring Instruments?
- RRebecca 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.
