DVC2000 Digital Valve Controller
The local user interface is available on all DVC2000
digital valve controllers. The interface consists of a
liquid crystal display, four pushbuttons, and a switch
for position transmitter configuration. The DVC2000 is
supplied with one of three different language packs
preinstalled, depending on the firmware revision and
ordering option. Language pack options are shown in
table 3-1. To configure the language, follow the
procedure outlined in the Basic Setup section. The
instrument must be powered with at least 8.5 volts and
3.5 mA to operate the local interface. Certain
procedures require up to 20 mA of current.

CAUTION
When accessing the terminals or
pushbuttons, proper means of
electrostatic discharge protection is
required. Failure to provide appropriate
protection can cause the valve to
move, resulting in valve/actuator
instability.
