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.
2. If a cam is not already installed on the actuator,
install the cam as described in the instructions
included with the mounting kit. For sliding-stem
actuators, the cam is installed on the stem connector.
3. If a mounting plate is required, fasten the mounting
plate to the actuator.
4. For applications that require remote venting, a
pipe-away bracket kit is available. Follow the
instructions included with the kit to replace the existing
mounting bracket on the digital valve controller with
the pipe-away bracket and to transfer the feedback
parts from the existing mounting bracket to the
pipe-away bracket.
5. Larger size actuators may require a follower arm
extension, as shown in figure 2-6. If required, the
follower arm extension is included in the mounting kit.
Follow the instructions included with the mounting kit
to install the follower arm extension.
6. Apply anti-seize (key 64) to the arm assembly pin
as shown in figure 2-8.
7. Mount the DVC6020f on the actuator as follows:
If required, a mounting adaptor is included in the
mounting kit. Attach the adaptor to the actuator as
shown in figure 2-5. Then attach the digital valve
controller assembly to the adaptor. The roller on the
digital valve controller feedback arm will contact the
actuator cam as it is being attached.

If no mounting adaptor is required, attach the
digital valve controller assembly to the actuator or
mounting plate. The roller on the digital valve
controller feedback arm will contact the actuator cam
as it is being attached.
8. For long-stroke sliding-stem actuators, after the
mounting is complete, check to be sure the roller
aligns with the position mark on the cam (see
figure 2-4). If necessary, reposition the cam to attain
alignment.
