DVC6000f Digital Valve Controllers
December 2009 2-24
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
2
) ground
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 wire ends.
e. The instrument is not polarity sensitive. Refer to
figure 2-19. 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 DVC6000, and
ensure that the shield is totally isolated at the
instrument end.

Note
The green/yellow wire is cut off inside
the DVC6000f 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.
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:
Emerson Process Management supplied
DVC6015, DVC6025 or DVC6035 feedback unit
An under-traveled 10 kOhm potentiometer used
in conjunction with onboard 30 kOhm resistor
(potentiometer travel is greater than actuator travel)
A potentiometer used in conjunction with two
fixed resistors (potentiometer travel is the same as
actuator travel)
