Why is HART communication not functioning on my Endress+Hauser Radar?
- AArthur PatelSep 12, 2025
If HART communication does not function on your Endress+Hauser Radar, consider the following: 1. Install the communication resistor (250 ?) correctly if it is missing or incorrectly installed. 2. Connect the Commubox correctly. 3. Set the selection switch of the Commubox to the HART position.
