Why is the 4 … 20 mA signal missing on my Siemens SITRANS LR100?
- D
  David TuckerSep 9, 2025
  If you observe that the 4 … 20 mA signal is missing on your Siemens Transmitter, it could be due to several reasons: a faulty electrical connection, a missing voltage supply, or an operating voltage that's too low with a load resistance that's too high. First, check the connection and correct if necessary. Next, inspect the cables for breaks and repair if needed. Finally, check and adapt the operating voltage and load resistance if necessary.
