Integral Mounted Fisher Actuators
1. Isolate the control valve from the process line pressure and release pressure from both sides of the valve body. Shut
off all pressure lines to the actuator, releasing all pressure from the actuator. Use lock‐out procedures to be sure
that the above measures stay in effect while you work on the equipment.
2. The DVC6200 digital valve controller mounts directly to an integral mounted Fisher actuator without the need for a
mounting bracket. Make sure you have the correct DVC6200 housing for your actuator, as shown in figure 1.
3. For GX actuators, identify the yoke side to mount the DVC6200 digital valve controller based on the actuator fail
mode. Refer to the GX Control Valve and Actuator System instruction manual (D103175X012
).
4. Loosely attach the feedback pieces and magnet assembly to the valve stem connector. Do not tighten the fasteners
because fine adjustment is required.
CAUTION
Do not install a magnet assembly that is shorter than the physical travel of the actuator. Loss of control will result from the
magnet assembly moving outside the range of the index mark in the feedback slot of the DVC6200 housing.
5. Using the alignment template (supplied with the mounting kit), position the feedback assembly inside the retaining
slot.
6. Continue on with the appropriate procedure below to align the magnet assembly.
