Feedback Unit Connections For Remote Mounting - Emerson Fisher Fieldvue DVC6030f Instruction Manual

Refer to figures 11-1, 11-2, 11-4 and 11-6 for
identification of parts.
WARNING
Personal injury or property damage,
caused by fire or explosion, can result
from the discharge of static electricity.
Connect a 14 AWG (2.08 mm
strap between the digital valve
controller and earth ground when
flammable or hazardous gases are
present. Refer to national and local
codes and standards for grounding
requirements.
To avoid static discharge from the
plastic cover, do not rub or clean the
cover with solvents. Clean with a mild
detergent and water only.
To avoid personal injury or property
damage, do not use the Quick
Connect option on instruments in
explosion-proof installations.
1. The quick connect cable entry should be installed
on the digital valve controller at the factory. If it is,
proceed to step 3. If not continue with step 2.
2. To install the Quick Connect:
a. Remove the terminal box cap (key 4) from the
terminal box (key 3).
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 ends of the wires.

e. The instrument is not polarity sensitive. Refer to
figure 2-17. Connect the blue wire to one of the
LOOP terminals in the terminal box. Connect the
brown wire to the other LOOP terminal. Connect
the green/yellow wire to the Safety Ground
terminal.
f. Replace the terminal box cap on the terminal
box.
3. Connect the field wiring connector to the installed
quick connector.

Feedback Unit Connections for Remote
Mounting
The DVC6005f base unit is designed to receive travel
information via a remote sensor. The remote can be
any of the following:
D Fisher supplied DVC6015, DVC6025 or
DVC6035 feedback unit
D An under-traveled 10 kOhm potentiometer used
in conjunction with onboard 30 kOhm resistor
(potentiometer travel is greater than actuator travel)
D A potentiometer used in conjunction with two
fixed resistors (potentiometer travel is the same as
actuator travel)
Using the DVC6015, DVC6025 & DVC6035
Feedback Unit as a Remote Travel Sensor
The feedback unit mounts on the actuator and is
connected to the base unit, mounted on a pipestand or
wall, with a 3-conductor shielded cable.
Connect the feedback unit to the base unit as follows,
refer to figure 2-19:
1. On the feedback unit, remove the housing cap.
2. On the base unit, remove the feedback
connections terminal box cap (see figure 2-15).
Installation
WARNING
Personal injury or property damage,
caused by wiring failure, can result if
the feedback wiring connecting the
base unit with the remote feedback
unit shares a conduit with any other
power or signal wiring.
Do not place feedback wiring in the
same conduit as other power or
signal wiring.
