Hi All,
I have a question about the input wiring on a HMISCU8B5. I am so close to having what I am after yet it seems so far away. I have attached a picture of what I am doing and it works fine as long as I hook only one of the 4-20ma inputs at a time. I want the HMISCU8B5 to take the place of the Kele LPI-1C's. I have to be missing something on the attached wiring diagram. How can terminal (D12) C2 be the same for both 4-20ma feedbacks? Like I said either or works fine by itself, meaning my JCI controller sees the same thing the HMI sees when either input is hooked up by itself. I just don't understand how this wiring schematic could work for two different 4-20ma signals. If anyone has any information or suggestions please let me know. Thanks.
