Yes, if current actual value is lower than 4 mA. |

Have checked your connection properly for the module in terms of Current? |

To check the same input with some other current (4-20 mA) configured channel has been told by me and also by Madhava. Just give it a try

Hello Hike, I have no direct answer to your question. I'd say, make sure your hardware configuration is done right and uploaded into the device. If your module contains a switchblock at the side of the card make sure that block is in the right position. Make sure you have no SF or that the card/sensor is defect. If all above is okay I could only explain the negative reading because in some way you are creating an overflow or underflow at the analog input of your card. I'd advice you to read up on how the analog input modules react when exceeding or deceeding ranges. Check out following links, they might be useful:
I hope I was able to help. Kind regards, Jens |
Keep it simple and on-topic. |

If the problem exist after changing sensors, then you may consider:- *sensor sheilding connection with panel earthing connections |
