Emerson Fisher DVC6200 Mounting Instructions

Mounting Instructions
D103439X012
May 2010
Use these instructions to mount a Fisher
DVC6200 or DVC2000 digital valve controller on Fisher
585C/585CR size 25 actuators with or without handjack
actuators.
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

effect while you work on the equipment.
2. During the attachment of the connector arm (key 3)
to the valve stem connector it will be necessary to
remove the stem connector cap screws and use the
longer cap screws (key 9). To reassemble the valve
stem connector use plain washer (key 8) and hex nut
(key 7). Install the connector arm (key 3) 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
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).
8. Attach the digital valve controller to the mounting
bracket and tighten the three hex head cap screws
(key 1b).
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.
