DVC6200f Digital Valve Controller
Basic Setup
February 2017
Typically Device Setup determines the required setup information based upon the actuator manufacturer and model
specified. However, if you enter OTHER for the actuator manufacturer or the actuator model, then you will be
prompted for setup parameters such as:
D Actuator Style—Select spring & diaphragm, piston double‐acting without spring, piston single‐acting with spring,
piston double‐acting with spring.
D Valve Style—Select the valve style, rotary or sliding‐stem.
D Zero Power Condition—this identifies whether the valve is fully open or fully closed when the input is 0%. If you are
unsure how to set this parameter, disconnect the instrument from the segment. (With double‐acting and
single‐acting direct digital valve controllers, disconnecting the instrument from the segment is the same as setting
the output A pressure to zero. For single‐acting reverse digital valve controllers, disconnecting the instrument from
the segment is the same as setting the output B pressure to supply.)
WARNING
If you answer YES to the prompt for permission to move the valve when setting the Travel Sensor Motion, the instrument
will move the valve through its full travel range. To avoid personal injury and property damage caused by the release of
pressure or process fluid, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the
process fluid.
D Travel Sensor Motion—Device Setup asks if it can move the valve to determine travel sensor motion. If you answer
Yes, the instrument will stroke the valve the full travel span to determine travel sensor motion. If you answer No,
then you must specify the direction of travel movement. For quarter‐turn actuators determine rotation by viewing
the rotation of the magnet assembly from the back of the instrument.
Note
Travel Sensor Motion in this instance refers to the motion of the magnet assembly. Note that the magnet assembly may be
referred to as a magnetic array in user interface tools.
For instruments with relay A or C If increasing air pressure at output A causes the magnet assembly to move up, or
the actuator shaft to rotate counterclockwise, enter "Towards Top of Instrument/CCW." If it causes the magnet
assembly to move down, or the actuator shaft to rotate clockwise, enter "Away From Top of Instrument/CW." For
instruments with relay B.
For instruments with relay B If decreasing air pressure at output B causes the magnet assembly to move up, or the
actuator shaft to rotate counterclockwise, enter "Towards Top of Instrument/CCW." If it causes the magnet
assembly to move down, or the actuator shaft to rotate clockwise, enter "Away From Top of Instrument/CW."
Note
Relay A adjustment may be required before Device Setup can determine travel sensor motion. Follow the prompts on the Field
Communicator display if relay adjustment is necessary.
Table 3‐2 lists the required Travel Sensor Motion selections for Fisher and Baumann actuators.
