Use these instructions to mount a FisherR FIELDVUEt
DVC6200 or DVC2000 digital valve controller on an
IEC60534-6-1 (old NAMUR) sliding stem actuator.

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 figures 3, 4 and 5 for mounting parts
identification. Refer to the DVC6200 or DVC2000
digital valve controller instruction manual for digital
controller 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. Two connector arms are provided (see figure 1),
one suitable for use with small actuators and one for
use with large actuators; select the appropriate one for

NAMUR) Sliding Stem Actuator

the actuator being used (figures 3, 4 and 5 show the
size for small actuators).

3. Ensure the actuator/valve stem connector mounting
face is visually square with the actuator yoke legs.

Attach the connector arm (key 7) to the stem connector
using the two hex head cap screws (key 3) and plain
washers (key 4), but do not tighten (see figures 3, 4
and 5).

4. Attach the mounting bracket (key 5) to the yoke leg
using the appropriate hardware for the actuator
mounting style.

a. Figure 3 shows pillar style mounting. For rough
alignment of pillar style actuators, center the
primary hole in the bracket with the approximate
mid-travel position of the stem connector. Visually
square up the bracket relative to the actuator yoke
legs, then tighten the fasteners.

b. Figure 4 shows rib style mounting. For rib style
mounting, select the primary hole for most
actuators. The alternate hole may be required for
small actuators.

c. Figure 5 shows plane surface style mounting.

5. Attach the magnet assembly (key 2) to the
extension arm (key 1) with two pan head machine
screws (key 6) but do not tighten.

6. Attach the extension arm and the magnet assembly
to the connector arm using two pan head machine
screws, (key 6) but do not tighten. The next step will
ensure that the connector arm selected is suitable.

7. Attach the black plastic alignment template to the
mounting bracket assembly by inserting the two
protruding posts into the two mounting holes in the
bracket and simultaneously position the magnet
assembly so that it can slide into the channel in the
alignment bracket. The magnet assembly should be
fully in the alignment template channel so that the
extension arm is contacting the back of the alignment
template but not bending it. Tighten the hex head cap
screws (key 3) at the stem connector and pan head
machine screws (key 6) attaching the extension arm to
the connector arm but do not yet tighten the pan head
machine screws attaching the magnet assembly.

8. For an air-to-extend actuator, slide the magnet
assembly (key 2) so that the bottom marking aligns
with the sensor index mark on the alignment template
(see figure 2). The top marking of the magnet assembly
is used for air-to-retract. The mounting bracket may
require vertical repositioning to get the magnet
assembly in the correct location. When the magnet
assembly is properly positioned, remove the alignment
template and tighten the two pan head machine screws
(key 6).

9. Attach the digital valve controller to the mounting
bracket assembly and tighten the three hex head cap
screws (key 9).

10. Check the position of the magnet assembly (key 2)
in the channel of the digital valve controller housing
and ensure that it is visually centered between the
channel walls and has adequate clearance with the
backside of the channel (approximately 3 mm).

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

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