The DVC6215 feedback unit uses a cam (designed for linear response) and roller as the feedback mechanism. See
figures 2‐12 and 2‐13.

All cams supplied with FIELDVUE mounting kits are characterized to provide a linear response.
There are three different mounting adaptions, based on the actuator design (see figure 2‐14).
Fisher Rotary Actuators
Refer to the following guidelines when mounting on rotary 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 pneumatic actuator, releasing all pressure from the actuator. Use lock‐out procedures to
be sure that the above measures stay in effect while working on the equipment.
