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 2 and the parts list for mounting parts
identification. Refer to the FIELDVUER DVC6000
Series Digital Valve Controller Instruction Manual,
Form 5647, or the FIELDVUER DVC6000f Series
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.

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 bracket
(key 11) 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 bracket (key 11) to the stem block
using plain washers (key 1) and hex head cap
screws (key 2).

5. Attach the cam (key 3) to the cam bracket using
plain washers (key 12), lock washers (key 13), and
hex head cap screws (key 14). Ensure that the cam
is oriented as shown in figure 2.

6. Attach the mounting adapter (key 4) to the yoke
using the four spacers (key 9) and four hex socket
cap screws (key 5).

7. 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.

8. In place of the roller, install the follower arm
extension (key 10) on the digital valve controller,
using two lockwashers (key 15), hex nuts (key 17),
and machine screws (key 16), as shown in figure 1.

9. Install the roller on the follower arm extension as
shown in figure 1, using the retained screw,
lockwasher and nut (key 87, 89, and 90).

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

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

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

13. Ensure that the cam is positioned so that when
the actuator stem is fully extended, the roller lines up
with either the lower mark on the cam (if valve travel
is 2 inches) or the upper mark on the cam (if valve
travel is 3 inches). See figure 2 for cam markings.

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

15. It may be necessary to fine tune the placement
of the cam so that the digital valve controller
receives the proper feedback. An easy way to do
this is to place the valve/actuator at mid travel and
adjust the cam while monitoring the feedback count
values using a HART host. Refer to appropriate
digital valve controller instruction manual to obtain
the target count values for a DVC6020.

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