Note
When performing the following steps,
ensure there is enough clearance
between the adjustment arm and the
feedback arm to prevent interference
with the bias spring.
7. Apply anti-seize (key 64) to the pin of the
adjustment arm. As shown in figure 2-3, place the pin
into the slot of the feedback arm or feedback arm
extension so that the bias spring loads the pin against
the side of the arm with the valve travel markings.
8. Install the external lock washer on the adjustment
arm. Position the adjustment arm in the slot of the
connector arm and loosely install the flanged hex nut.
9. Slide the adjustment arm pin in the slot of the
connector arm until the pin is in line with the desired
valve travel marking. Tighten the flanged hex nut.
10. Remove the alignment pin (key 46) and store it in
the module base next to the I/P assembly.
11. After calibrating the instrument, attach the shield
with two machine screws.
DVC6020f on Long-Stroke (4 to 24 Inch
Travel) Sliding-Stem Actuators and
Rotary 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.
Note
All cams supplied with FIELDVUE
mounting kits are characterized to
provide a linear response.
