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 pin of the
adjustment arm as shown in figure 2-7.
7. Mount the DVC6020 SIS 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.
DVC6030 SIS on Quarter-Turn Actuators
If ordered as part of a control valve assembly, the
factory mounts the digital valve controller on the
actuator, makes pneumatic connections to the
actuator, sets up, and calibrates the instrument. If you
purchased the digital valve controller separately, you
will need a mounting kit to mount the digital valve
controller on the actuator. See the instructions that
come with the mounting kit for detailed information on
mounting the digital valve controller to a specific
actuator model.
Figure 2-8 shows the DVC6030 SIS digital valve
controller mounted on a quarter-turn actuator. Refer to
figure 2-8 for parts locations. Refer to the following
guidelines when mounting on quarter-turn actuators:
Note
Due to NAMUR mounting limitations,
do not use the stainless steel
DVC6030S SIS in high vibration service.
