Size 20 and 33 ActuatorV (Window Mount)

Use these instructions to mount a Fisher® FIELDVUETM
DVC6200 or DVC2000 digital valve controller on Fisher
1051 Size 33 and 1052 Size 20 and 33 actuators.

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 2 and the parts list for mounting parts
identification. Refer to the DVC6200 or DVC2000 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. Remove the cover plate screws and cover plate from
the actuator, if present.

3. Install the cam (key 1) on to the lever of actuator using
hex head mach screws (key
use of arced feedback mechanism. Consult the
appropriate actuator instruction manual for proper
actuator disassembly and reassembly. Ensure that the
cam is oriented as shown in figure 2.

4. Attach the mounting adaptor (key 3) to the yoke using
the four hex socket cap screws (key 4).

5. Attach the digital valve controller to the arced
feedback assembly (key 5) and tighten the hex socket
cap screws (key 6).

6. Install the arced feedback assembly (key 5), along
with the digital valve controller, to the mounting adaptor
(key 3) using hex socket cap screws (key 7) as shown in
figure 2. Ensure that the roller of arced feedback
assembly is centered and resting on the cam surface.

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

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

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

For additional information concerning mounting, setup,
calibration, and maintenance of the DVC6200 or
DVC2000 digital valve controller, refer to the appropriate
instruction manual.
