Use these instructions to mount a Fisher® FIELDVUETM
DVC6200 digital valve controller on Fisher 585C and
471 Size 60 -130 actuators, with 0.56 to 4 inch travel,
except 585C Size 68.

Avoid personal injury or property damage from
sudden re
of parts. Before performing any installation
operations:

lease of process pressure or bursting

 Always wear protective clothing, gloves,

and eyewear.

 Do not remove the actuator from the valve

while the valve is still pressurized.

 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.

 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.

 Vent the pneumatic actuator loading

pressure and relieve any actuator spring
precompression.

 Use lock-out procedures to be sure that

the above measures stay in effect while you
work on the equipment.

 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.

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 cam (key 2) to the valve
stem connector it will be necessary to remove the stem
connector cap screws. Consult the appropriate actuator

and 471 Size 60-130 with 0.56 to 4 Inch Travel

Except 585C Size 68 (Linear Roller Cam)

instruction manual for proper actuator disassembly and
reassembly.

3. Attach the cam (key 2) to the stem connector using
two stud bolts (key 1), four plain washers (key 3) and
four hex nuts (key 4). In addition to this, use spacers
(key 5) to attach the cam to stem connector, if provided,
as shown in figure 4.

4. Attach plate
mounting face
hex head screws (key 8). Similarly, attach the mounting
plate to bottom yoke mounting by using a spacer (key 9),
stud (key 10), plain washer (key 11) and hex nut
(key 12).

5. Attach the digital valve controller to the arced
feedback assembly (key 15) using the four metric hex
socket cap screws (key 14).

6. Attach the arced feedback assembly along with the
digital valve controller to the mounting plate using the
four imperial hex socket cap screws (key 13) as shown
in figure 3. Ensure that the roller of arced feedback
assembly is centered and resting on the cam surface as
shown in figure 2.

7. Ensure that the cam is positioned so that when the
actuator stem is fully retracted the roller lines up with the
mark on the cam.

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

9. It may be necessary to fine tune the placement of the
cam so that the digital valve controllers receives the
proper feedback, by lining up as shown in figure 2.

10. Setup and
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.
