Wiring and Electrical Connections

Fieldbus Connections

The digital valve controller is normally powered over
the bus from a fieldbus power supply. Refer to the site
planning guide for proper wire types, termination,
length, etc. for a fieldbus loop.
Note
As shipped from the factory, the
DVC6200f digital valve controller will
not move the valve when power is
applied to the instrument. To avoid the
valve going to an unknown position
when power is applied, the unit is
shipped from the factory with the
transducer block mode Out of Service.
See the Basic Setup section for
information on setup and calibration
and placing the instrument in service.
WARNING
To avoid personal injury resulting
from electrical shock, do not exceed
the maximum input voltage specified
in table 1-1 of this quick start guide,
or on the product nameplate. If the
input voltage specified differs, do not
exceed the lowest specified maximum
input voltage.
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 cover before
proceeding.

Making Fieldbus Connections with
Twisted Shielded Pair
Refer to figure 8-2 for identification of parts.
Wire the digital valve controller as follows, refer to
figure 2-8:
1. Remove the wiring terminal box cap.
2. Bring the field wiring into the terminal box. When
applicable, install conduit using local and national
electrical codes which apply to the application.
3. The instrument is not polarity sensitive. Connect
one wire from the control system output card to one of
