DVC6200 positioner is only giving output to close and open valve no midrange control. eg. 50% input, it open 100%. it is a new positioner. at the end the positioner quit altogether, no output regardless of the input. I did not install it, I was just tasked to test it.
what could be the reason for this problem? pls help.
