Hi, Good day! I would like to ask regarding my project, I'm using V350 35 R22 and having a modulating valve as a controlled instrument using plc analog output. My problem is that I can't control the valve on below 50% openning (below ~11mA output) however, I can actuate the valve or command on 50% - 100% opening (12mA - 20mA output). I've tried to isolate the plc output to verify the output current and it seems fine (4mA - 20mA) Also, I've tried to insert a ammeter to check the loop current while the plc's injecting current to instrument, 12mA-20mA was OK but when the plc's inject belo
