Use these instructions to mount a Fisherr FIELDVUEt
DVC6200 digital valve controller on Fisher 585C size
68 actuator with 2.01 to 4.00 inch travel.

4.00 Inch Travel (Linear Roller Cam)

WARNING

Avoid personal injury or property
damage from sudden release of process
pressure or bursting of parts. Before
performing any maintenance operations:

D Always wear protective clothing,

gloves, and eyewear.

D Do not remove the actuator from
the valve while the valve is still
pressurized.

D Disconnect any operating lines
providing air pressure, electric power, or
a control signal to the actuator. Be sure
the actuator cannot suddenly open or
close the control valve.

D Use bypass valves or completely
shut off the process to isolate the
control valve from process pressure.
Relieve process pressure from both
sides of the control valve.

D Vent the pneumatic actuator
loading pressure and relieve any
actuator spring precompression.

D Use lock-out procedures to be sure
that the above measures stay in effect
while you work on the equipment.

D Check with your process or safety
engineer for any additional measures
that must be taken to protect against
process media.

Refer to figure 3 and the parts list for mounting parts
identification. Refer to the DVC6200 digital valve
controller instruction manual for digital valve controller
parts identification. Refer to the appropriate actuator
instruction manual for actuator installation, operation,
maintenance, and parts identification. Figure 1 shows
the arced feedback assembly (RShaft Window #1).

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 actuator,
releasing all pressure from actuator. Use lock-out
procedures to be sure that the above measures stay in
effect while you work on the equipment.

2. During the attachment of the cam bracket (key 2) to
the valve stem connector it will be necessary to remove
the stem connector cap screws. Consult the
appropriate actuator instruction manual for proper
actuator disassembly and reassembly.

3. Attach the cam bracket (key 2) to the stem
connector using two stud bolts (key 1), two plain
washers (key 4), two lock washers (key 3) and four hex
nuts (key 5).

4. Attach the cam (key 7) to the cam bracket using two
plain washers (key 4), two lock washers (key 3), two
hex head screws (key 8), and two hex nuts (key 5).
Use spacers (key 6) in between cam and cam bracket.
Ensure that the cam is oriented as per the mounting
assembly drawing.

5. Attach the mounting plate (key 9) to the actuator
yoke top mounting face using two lock washers
(key 10) and two hex head screws (key 11).
Additionaly, use the spacer (key 12) in between the
mounting plate and the yoke mounting face, as shown
in figure 3. Similarly, attach the mounting plate to the
bottom yoke mounting by using a spacer (key 14), stud
(key 13), plain washer (key 15), lock washer (key 10)
and hex nut (key 16).

6. Attach the digital valve controller to the arced
feedback assembly (key17) using the four metric hex
socket cap screws (key 19).

7. Attach the arced feedback assembly along with the
digital valve controller to the mounting plate using the
four imperial hex socket cap screws (key 18) as shown
in figure 3. Ensure that the roller of the arced feedback
assembly is centered and resting on the cam surface
as shown in figure 2.

8. Ensure that the cam is positioned so that when the
actuator stem is fully extended, the roller lines up with
the mark on the cam.

9. Make pneumatic and electrical connections to the
digital valve controller as described in the digital valve
controller instruction manual.

10. It may be necessary to fine tune the placement of
the cam so that the digital valve controller receives the
proper feedback.

11. Setup and calibrate the digital valve controller as
described in instruction manual or quick start guide.

For additional information concerning mounting, setup,
calibration, and maintenance of the DVC6200 digital
valve controller, refer to the appropriate instruction
manual.
