DVC6000f Digital Valve Controllers
December 2009 3-2
Basic Setup
WARNING
Changes to the instrument setup may
cause changes in the output pressure
or valve travel. Depending on the
application, these changes may upset
process control, which may result in
personal injury or property damage.
When the DVC6000f digital valve controller is ordered
as part of a control valve assembly, the factory
mounts the digital valve controller and sets up the
instrument as specified on the order. When mounting
to a valve in the field, the instrument needs to be
setup to match the instrument to the valve and
actuator.
Before beginning basic setup, be sure the instrument
is correctly mounted as described in the Installation
section.
Basic Setup includes the following procedures:
Device Setup
Auto Travel Calibrate
Performance Tuner (Optional)
Note
The DVC6000f may keep the
Transducer Block Mode
Out-of-Service if the instrument is
not properly mounted.
To setup and calibrate the
instrument, the Transducer Block
Mode must be Manual, and the
Protection must be None.
When using DD methods the
method will request that you
change the mode, but make
changes in Protection
automatically.

If you have a host system that
overrides transducer block
parameters ensure that the Protection
setting is not left as None. Doing so
will result in transducer block
parameters being overwritten.
