figure 2-4). If necessary, reposition the cam to attain
alignment.
DVC6035 on Quarter-Turn Actuators
If ordered as part of a control valve assembly, the
factory mounts the remote feedback unit on the
actuator, makes pneumatic connections to the
actuator, sets up, and calibrates the instrument. If you
purchased the remote feedback unit separately, you
will need a mounting kit to mount the remote feedback
unit on the actuator. See the instructions that come
with the mounting kit for detailed information on
mounting the remote feedback unit to a specific
actuator model.
Note
Refer to the DVC6005 Base Unit
mounting instructions on page 2-13 for
off-actuator mounting instructions.
Figure 2-8 shows an example of mounting 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
While the housing differs on the
DVC6035 and the DVC6030, feedback
parts are the same.
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.
2. If necessary, remove the existing hub from the
actuator shaft.
3. If a positioner plate is required, attach the
positioner plate to the actuator as described in the
mounting kit instructions.

4. If required, attach the spacer to the actuator shaft.
Refer to figure 2-14. The travel indicator assembly can
have a starting position of 7:30 or 10:30. Determine
the desired starting position then proceed with the next
step. Considering the top of the remote travel sensor
as the 12 o’clock position, in the next step attach the
travel indicator, so that the pin is positioned as follows:
If increasing pressure from the base unit
output A rotates the remote feedback units
potentiometer shaft counterclockwise (as viewed
from the back of the instrument), mount the travel
indicator assembly such that the arrow is in the 7:30
position, as shown in figures 2-10 and 2-14.
If increasing pressure from the base unit
output A rotates the remote feedback units
potentiometer shaft clockwise (as viewed from the
back of the instrument), mount the travel indicator
assembly such that the arrow is in the 10:30 position,
as shown in figures 2-9 and 2-14.
