b. Apply sealant to the threads of the quick
connector.
c. Insert the wire pigtail into the desired conduit
opening on the terminal box. Tighten the quick
connector in the conduit opening.
d. Cut and trim the wire ends.
e. The instrument is not polarity sensitive. Refer to
figure 2-8. Connect the blue wire to one of the
LOOP terminals in the terminal box. Connect the
brown wire to the other LOOP terminal. Cut the
green/yellow wire off inside of the DVC6200f, and
ensure that the shield is totally isolated at the
instrument end.
Note
The green/yellow wire is cut off inside
the DVC6200f to help prevent ground
loop issues. The only wires that
should be installed and left on the
connector are the two signal wires.
f. Replace the terminal box cap on the terminal
box.
3. Connect the field wiring connector to the installed
quick connector.
Communication Connections
WARNING
Personal injury or property damage
caused by fire or explosion may occur
if this connection is attempted in a
potentially explosive atmosphere or in
an area that has been classified as
hazardous. Confirm that area
classification and atmosphere
conditions permit the safe removal of
the terminal box cap before
proceeding.

OUNDATION
fieldbus communicating device, such
as a Field Communicator or a personal computer
running ValveLink software, interfaces with the
DVC6200f digital valve controller from any wiring
termination point in the segment. If you choose to
connect the fieldbus communicating device directly to
the instrument, attach the device to the LOCAL
connections inside the terminal box to provide local
communications with the instrument.
Simulate Enable Jumper
WARNING
Personal injury or property damage
caused by fire or explosion may occur
if this connection is attempted in a
potentially explosive atmosphere or in
an area that has been classified as
hazardous. Confirm that area
classification and atmosphere
conditions permit the safe removal of
the terminal box cap before
proceeding.
Install a jumper across the SIMULATE ENABLE
terminals to enable the instrument to accept a
simulate command. (These terminals are marked AUX
on the terminal board, see figure 2-8). With the jumper
in place and the simulate parameter in the AO or DO
block set to enabled, the transducer block ignores the
output of the AO or DO block. The simulate value and
status become the readback value and status to the
AO or DO block and the transducer block is ignored.
For more information on running simulations, see the
Detailed Setup section of this manual, the

OUNDATION
fieldbus specifications, and the host
documentation.
WARNING
Removing the jumper will disable the
simulate, which may cause the valve
to move. To avoid personal injury and
property damage caused by the
release of pressure or process fluid,
provide some temporary means of
control for the process.
