Information:
DVC 6200 Valve.
Condition:
The valve is not operating.

MOG’s Solutions:
Removed the positioner for inspection; based on the screen not displaying anything when powered, identified the cause as a faulty main circuit board.
Tested by replacing the main circuit board with another of the same type.
Installed the positioner on the valve and checked operation; the valve functioned normally.
Proceeded to order and fully replace the main circuit board to restore normal DVC operation
