Use these instructions to mount a Fisher
R
FIELDVUE
t
DVC6200 or DVC2000 digital valve controller on Fisher
585C/585CR size 50 actutaors with or without
handjack.
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 figure 2 and the parts list 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.
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 stem connector cap screws and use
the longer cap screws (key 9) to attach the connector
arm (key 3) to the valve stem connector. Reassemble
the valve stem connector using the spacers (key 10)
and two hex nuts (key 7). Install the connector arm (key
3) using the plain washer (key 8) and the two remaining
hex nuts (key 7) when reassembling the valve stem
connector.
3. Attach the extension arm (key 6) to the connector
arm using two pan head machine screws (key 4) but do
not tighten. See figure 2 for extension arm orientation.
4. Attach the magnet assembly (key 5) to the
extension arm with two pan head machine screws
(key 4) but do not tighten (the magnet assembly can be
inverted 180
_
without effect).
5. Attach the mounting bracket assembly (key 1) to the
yoke using the two socket head screws (key 2).
6. Push the cap screws and the O-ring in the mounting
bracket groove and then attach the black plastic
alignment template to the mounting bracket by inserting
the two protruding posts into the mounting holes in the
bracket and simultaneously positioning the magnet
assembly so that it can slide into the channel in the
alignment template. 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 pan head machine
screws (key 4), attaching the extension arm to the
connector arm but do not yet tighten the pan head
machine screws attaching the magnet assembly.
7. For an air-to-extend actuator, slide the magnet
assembly (key 5) so that the bottom marking aligns with
the sensor index mark on the alignment template (see
figure 1). The magnet assembly’s top marking 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 4).
