Use these instructions to mount a Fisherr FIELDVUEt
DVC6200 or DVC2000 digital valve controller on Fisher
1051 and 1052, size 40 through 70 actuators.

Size 40−70 Actuators (End Mount)

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

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 2 and the parts list for mounting parts
identification. Refer to the DVC6200 or DVC2000
instruction manual for instrument 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 the actuator. Use lock-out
procedures to be sure that the above measures stay in
effect while you work on the equipment.

2. The instrument can be mounted in four different
orientations on the 1051 or 1052. Figure 1 shows the
instrument mounted upright rela tive to the actuator spring
barrel.

3. Attach the coupler (key 1) to the actuator shaft using
the hex head machine screws (key 2) and tighten. For
best visibility, the coupler should be oriented on the shaft
so that the pointer will rotate in the quadrant above or
below the instrument as shown in figure 2.

4. Remove the four actuator cap screws attaching the
actuator cover, but leave the cover in place.

5. Attach the mounting bracket (key 3) to the actuator
cover, but do not tighten the cap screws.

6. Place the pointer (key 4) before attaching the magnet
assembly (key 5) to the coupler using pan head screws
(key 6) and tighten.

The magnet assembly must be oriented per figure 1, so
that the flats are approximately as shown relative to the
channel in the instrument housing when at the
mid-travel position.

7. Adjust the mounting bracket so that the magnet
assembly is visually centered in the mounting bracket
center hole and tighten the four cover cap screws.

8. Attach the mounting posts (key 7) to the mounting
bracket and tighten.

9. Attach the travel indicator scale (key 8) to the
mounting post using two plain washers (key 9) and pan
head machine screws (key 10). Refer to figure 2.

10. Attach the digital valve controller to the mounting
bracket using four hex head cap screws (key 11) but do
not tighten the screws. Visually adjust the digital valve
controller so that the magnet assembly is centered in the
housing channel and then tighten the fasteners. Recheck
the magnet assembly position again after tightening.

11. Connect and calibrate the instrument as described
in the appropriate instruction manual.

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