In this System your primary element is sending 1v - 5v to your controller and our controller is sending 4mA - 20mA to your final Element. 1) The Primary Element is sending 2.8v. Your controller is reading 2.8v. The Controller sends 5.2mA to the Final Element but nothing changes in your Process Variable. What is wrong? Controller Final Element Transmitter Wire 2) The Primary Element is sending 12v. Your controller is reading 12v. The Controller sends 0mA to the Final Element. What is wrong? Controller Final Element Transmitter Wire
