I have two fisher DVC 6030 positioners installed on two valve actuators whose valves have a common suction and discharge. I need to split range them.
One of the actuators is pre-existing, its controller has been fully configured, actuator type etc., however in order to split range these valves I need to change the controller's analog high range input from 20 mA to 12 mA. When I go online with the Hart Communicator I am able to view the analog high range input, but am unable to change it. Do I need to remove protection somehow? Do I need to install a jumper on the aux contacts? The fisher representative I talked to said that in order to change these input values I had to drive the positioner with 6mA plus, I did this and it didn't change anything. Please Help!!!
