Valve And Actuator - Fisher FIELDVUE DVC6200 Instruction Manual

Configuration
February 2017
is configurable from 0% to 2%, corresponding to a symmetric window from 0% to +/-2% around the Primary
Setpoint. Default value is 0.25%.
D Integrator Limit—The Integrator Limit provides an upper limit to the integrator output. The high limit is configurable
from 0 to 100% of the I/P drive signal.

Valve and Actuator

Field Communicator Configure > Manual Setup > Valve and Actuator (2‐2‐5)
Valve Style—Enter the valve style, rotary or sliding‐stem
Actuator Style—Enter the actuator style, spring and diaphragm, piston double‐acting without spring, piston
single‐acting with spring, or piston double‐acting with spring.
Feedback Connection—Refer to table 3‐6 for Feedback Connection options. Choose the assembly that matches the
actuator travel range.
Note
As a general rule, do not use less than 60% of the magnet assembly travel range for full travel measurement. Performance will
decrease as the assembly is increasingly subranged.
The linear magnet assemblies have a valid travel range indicated by arrows molded into the piece. This means that the hall sensor
(on the back of the DVC6200 housing) has to remain within this range throughout the entire valve travel. The linear magnet
assemblies are symmetrical. Either end may be up.

Relay Type—There are three categories of relays that result in combinations from which to select.
Relay Type: The relay type is printed on the label affixed to the relay body.
A = double‐acting or single‐acting
B = single‐acting, reverse
C= single‐acting, direct
Special App: This is used in single‐acting applications where the "unused" output port is configured to read the
pressure downstream of a solenoid valve.
Lo Bleed: The label affixed to the relay body indicates whether it is a low bleed version.
