Linear - Fisher FIELDVUE DVC2000 Quick Start Manual

DVC2000 Digital Valve Controller
July 2017
The factory default characteristic is LINEAR. You can also use a QUICK OPEN, EQUAL %, or CUSTOM function. However,
the custom function is initially configured linear, unless you use a HART based host to reconfigure the custom points.
Custom configuration can be selected, but the curve cannot be modified with the local interface.

Transmitter—This configures the relationship between the valve travel and the position transmitter output signal. If
you select CLOSED, the transmitter will send 4 mA when the valve is closed. If you select OPEN, the transmitter will
send 4 mA when the valve is open.
A switch is located on the options board to select the transmitter fail signal (high+ or low-). High+ will result in a
current output of > 22.5 mA upon transmitter failure. Low- will result in a current output of < 3.6 mA. Refer to figure
21 for location and switch selection.
