DVC6200 Digital Valve Controller

ounting Instructions

D103452X012
May 2010

Use these instructions to mount a Fisher® FIELDVUE™
DVC6200 digital valve
80-100 actuator.

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

 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 for mounting parts identification for
1061 Size 80-100. Refer to the DVC6200 digital valve
controller instruction manual for parts identification.
Refer to the appropriate actuator instruction manual for
actuator installation, operation, maintenance, and parts
identification.

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. Remove the cover plate screws and cover plate from
the actuator, if present.

3. Install the cam (key 1) on to the lever of the actuator. It
is necessary for use of arced feedback mechanism.
Consult with the appropriate actuator instruction manual
for proper actuator disassembly and reassembly.

4. Attach the cam (key 1) to the lever arm of the actuator
using hex head cap screws (key 2).
Ensure that th

5. Detach the roller assembly from the arced feedback
arm.

6. Refer to figure 2, attach the follower arm extension
(key 3) to the arc feedback arm using hex head cap
screws (key 4), lock spring washers (key 5) and hex nuts
(key 6).

7. Attach the roller assembly to the follower arm
extension (key 3) as shown in figure 2.

8. Attach the digital valve controller to the arced feedback
assembly (key 7) as per the actuator requirement using
hex socket cap screws (key 8).

9. Attach the arced feedback assembly (key 3), along with
the digital valve controller to the yoke of actuator using
hex socket cap screws (key 9) as shown in figure 3.

10. Ensure that the roller of arced feedback assembly is
centered and resting on the cam surface.

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

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

13. Setup and calibrate the digital valve controller as
described in the digital valve controller 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.

e cam is oriented as show

n in figure 3.
