DVC6000 Digital Valve Controllers
September 2013 4-4
Note
If the Auxiliary Terminal Action is
configured for Auto Travel Calibration,
be sure the jumper remains across the
auxiliary terminals until the Field
Communicator prompts you to remove
it. Removing the jumper too soon will
cause the instrument to begin auto
travel calibration.
WARNING
If the jumper is removed too soon,
and auto travel calibration begins, the
valve will move full stroke. To avoid
personal injury and property damage
caused by the release of pressure or
process fluid, provide some
temporary means of control for the
process.
Two levels of protection are available:
Config & Calib—Both setup and calibration are
protected. Prohibits changing calibration and protected
setup parameters.
None—Neither setup nor calibration is protected.
Allows changing calibration and setup parameters.
Table 4-3 lists configurable parameters in the
instrument and the requirements for modifying these
parameters, in terms of instrument mode and
protection.
To change an instrument’s protection, press the Hot
key on the Field Communicator and select Protection
or from the Online menu, select Configure, Detailed
Setup, Mode and Protection, and Protection. Select
the desired level of protection. Follow the prompts on
the Field Communicator display to set the protection
level. If necessary, temporarily attach the jumper to
the AUX + and AUX
−
terminals in the instrument
terminal box when prompted by the Field
Communicator.
Response Control (1-2-2)
Select Configure, Detailed Setup, and Response
Control. Follow the prompts on the Field
Communicator display to configure the following
response control parameters: Tuning, Travel/Pressure
Control, Input Characterization, Custom
Characterization Table, and Dynamic Response.
Tuning
Travel Tuning (1-2-2-1-1)
WARNING
Changes to the tuning set may cause
the valve/actuator assembly to stroke.
To avoid personal injury and property
damage caused by moving parts,
keep hands, tools, and other objects
away from the valve/actuator
assembly.
Travel Tuning Set— There are eleven tuning sets to
choose from. Each tuning set provides a preselected
value for the digital valve controller gain settings.
Tuning set C provides the slowest response and M
provides the fastest response. Table 4-2 lists the
proportional gain, velocity gain and minor loop
feedback gain values for preselected tuning sets.
