WARNING

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

D Always wear protective clothing,

gloves, and eyewear.

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 1 and the parts list for mounting parts
identification. Refer to the FIELDVUE
Series Digital Valve Controller Instruction Manual,
Form 5647, or the FIELDVUE
Digital Valve Controller Instruction Manual, Form 5774
for digital valve 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.

WARNING

To avoid personal injury due to the
sudden, uncontrolled movement of
parts, do not loosen the stem connector
cap screws when the stem connector
has spring force applied to it.

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

3. During the attachment of the cam (key 1) to the
valve stem connector it will be necessary to loosen the
stem connector cap screws. Consult the appropriate
actuator instruction manual for proper actuator
disassembly and reassembly.

4. Attach the cam to the stem block using hex head
cap screws (key 2). Ensure that the cam is oriented as
shown in figure 1.

5. Attach the mounting adapter (key 7) to the yoke
using the four spacers (key 9) and the four cap screws
(key 6).

6. Remove the roller from the digital valve controller by
removing the screw, lockwasher and nut (key 87, 89,
and 90; refer to the appropriate digital valve controller
instruction manual for parts identification, if necessary).
Retain the screw, lockwasher, and nut.

7. In place of the roller, install the follower arm
extension (key 12) on the digital valve controller, using
two machine screws (key 3), lockwashers (key 4), and
machine screw hex nut (key 5), as shown in figure 2.

8. Install the roller (key 13) on the follower arm
extension (key 12) as shown in figure 2, using the
retained screw, lockwasher and nut (key 87, 89,
and 90)

9. Install the vent adapter (key 10) and vent (key 11)
on the digital valve controller pressure outlet.

10. Mount the digital valve controller on the mounting
adapter (key 7) using four hex socket cap screws
(key 8).

11. Ensure that the roller is centered and resting on
the cam surface.

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

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

14. Re-attach actuator cover plate, if necessary.
