Instrument Description
The DVC2000 digital valve controller is a communicating, microprocessor-based current-to-pneumatic valve
positioner. It is designed to replace standard pneumatic and electro-pneumatic valve positioners.
In addition to the traditional function of converting an input current signal (4-20 mA) to a pneumatic output pressure,
the DVC2000 digital valve controller communicates via a local display panel and/or via the HART® protocol. An option
is available which provides isolated circuitry for two (2) integrated limit switches (for open/close valve indication) and a
valve position transmitter (for separate valve position feedback).

Terminology
Instrument Level— There are four (4) levels of functionality available: AC, HC, AD and PD.
AC—This level provides the capability to setup and calibrate the positioner through the local user interface or the Field
Communicator.
HC—This level provides additional capability for advanced configuration of the positioner (such as travel limits/cutoffs,
custom characterization, and minimum open/closing time). Also, information is available through the HART protocol
for diagnostic alerts such as travel deviation, cycle count, and travel accumulation.
AD—This level provides advanced diagnostic capabilities for performance testing. When used with ValveLink software,
instrument health can be evaluated with tests such as Valve Signature, step response and dynamic error band. The
software program provides detailed analysis with graphics.
PD—This level provides automated, non-intrusive testing of the operating performance of the control valve assembly.
When used with ValveLink
affecting the process.
software, tests to isolate component degradation can be run on the valve assembly without
Local Interface— The DVC2000 comes standard with a Liquid Crystal Display (LCD) and four (4) pushbuttons. The local
interface provides the capability to setup and calibrate the positioner and view basic diagnostic messages.
Magnet Assembly—This is the feedback component that is mounted directly to the valve stem. It supplies a magnetic
field that is sensed by the digital valve controller.
Options Board—The DVC2000 digital valve controller is available with two (2) limit switches and a valve position
transmitter. The options board includes the additional circuitry and terminations that are required to support these
output signals.
Pole Piece—Inserted into the DVC2000 housing and protruding through the back of the instrument is a two-pronged
fork that houses the magnetic sensor for position feedback.

Detailed Setup and Calibration

Section 2 Detailed Configuration and Calibration via HART
Communication
2‐2‐
Detailed Setup
The DVC2000 digital valve controller has the capability to communicate via the HART protocol. This section describes
the advanced features that can be accessed with the Field Communicator. Table 2‐1 lists the default settings for a
standard factory configuration. Table 2‐2 provides the actuator information required to setup and calibrate the
instrument.
Setting Modes
Field Communicator Setup & Diag > Detailed Setup > Mode (1-2-1)
Instrument Mode
You can change the instrument mode by selecting Instrument Mode from the Mode menu, or press the Hot Key and
select Instrument Mode.
Instrument Mode allows you to either take the instrument Out Of Service or place it In Service. Taking the instrument
Out Of Service allows you to perform instrument calibration and also allows you to change setup variables that affect
control, provided the calibration/configuration protection is properly set. See Setting Protection.
Note
Some changes that require the instrument to be taken Out Of Service will not take effect until the instrument is placed back In
Service or the instrument is restarted.
Control Mode
You can change the control mode by selecting Control Mode from the Mode menu, or press the Hot Key and select
Control Mode.
Control Mode lets you define where the instrument receives its set point. Follow the prompts on the Field
Communicator display to choose one of the following control modes: Analog or Digital.
Choose Analog if the instrument is to receive its set point over the 4-20 mA loop. Normally the instrument control
mode is Analog.
Choose Digital if the instrument is to receive its set point digitally, via the HART communications link.
A third mode, Test, is also displayed. Normally the instrument should not be in the Test mode. The Field
Communicator automatically switches to this mode whenever it needs to stroke the valve, for example during

calibration or stroke valve. However, if you abort from a procedure where the instrument is in the Test mode, it may
remain in this mode. To take the instrument out of the Test mode, select Control Mode then select either Analog or
Digital.
Restart Control Mode
Restart Control Mode (Restart Cont Mode) lets you choose which operating mode you want the instrument to be in
after a restart. Follow the prompts on the Field Communicator display to define the restart control mode as Resume
Last, Analog, or Digital.
Restarting the Instrument
Restart resets the instrument in the same manner as when power to the instrument is interrupted. When Restart is
issued, all of the newly entered configuration variables become active. Otherwise, they may not take effect until the
instrument is placed In Service.
Burst Mode
Enabling burst mode provides continuous communication from the digital valve controller. Burst mode applies only to
the transmission of burst mode data (analog input, travel target, pressure, and travel) and does not affect the way
other data is accessed.
Access to information in the instrument is normally obtained through the poll/response of HART communication. The
Field Communicator or the control system may request any of the information that is normally available, even while
the instrument is in burst mode. Between each burst mode transmission sent by the instrument, a short pause allows
the Field Communicator or control system to initiate a request. The instrument receives the request, processes the
response message, and then continues “bursting” the burst mode data.
There are four burst mode commands. Command 3 is recommended for use with the Rosemount
Tri-Loop
™
HART-to-analog signal converter. The other three are not used at this time.
™
333 HART
Command 3 provides the following variables:
D Primary variable—analog input in % or mA,
D Secondary variable—travel target (valve set point) in % of ranged travel,
D Tertiary variable—output pressure in psig, bar, or kPa,
D Quaternary variable—travel in % of ranged travel.
To enable burst mode select Mode > Burst > Burst Enable. To send a burst mode command, select Burst Command.
Burst mode must be enabled before you can change the burst mode command.

General Information
Field Communicator Setup & Diag > Detailed Setup > General (1-2-3)
Follow the prompts on the Field Communicator to enter or view information in the following fields:
D HART Tag—Enter an up to 8 character HART tag for the instrument. The HART tag is the easiest way to distinguish
between instruments in a multi-instrument environment. Use the HART tag to label instruments electronically
according to the requirements of your application. The tag you assign is automatically displayed when the Field
Communicator establishes contact with the digital valve controller at power-up.
D Message—Enter any message with up to 32 characters. Message provides the most specific user-defined means for
identifying individual instruments in multi-instrument environments.
D Descriptor—Enter a descriptor for the application with up to 16 characters. The descriptor provides a longer
user-defined electronic label to assist with more specific instrument identification than is available with the HART
tag.
D Date—Enter a date with the format MM/DD/YY. Date is a user-defined variable that provides a place to save the date
of the last revision of configuration or calibration information.
D Valve Serial Num—Enter the serial number for the valve in the application with up to 12 characters.
D Inst Serial Num—Enter the serial number on the instrument nameplate, up to 12 characters.
D Polling Address—If the digital valve controller is used in point-to-point operation, the Polling Address is 0. When
several devices are connected in the same loop, such as for split ranging, each device must be assigned a unique
polling address. The Polling Address is set to a value between 0 and 15. To change the polling address the
instrument must be Out Of Service.
For the Field Communicator to be able to communicate with a device whose polling address is not 0, it must be
configured to automatically search for all or specific connected devices.

Follow the prompts on the Field Communicator to define the following measured variables units and ranges:
D Analog In Units—Permits defining the Analog Input Units in mA or percent of 4-20 mA range.
D Input Range Hi—Permits setting the Input Range High value. Input Range High should correspond to Travel Range
High, if the Zero Control Signal is configured as closed. If the Zero Control Signal is configured as open, Input Range
High corresponds to Travel Range Low. See figure 2‐1.
D Input Range Lo—Permits setting the Input Range Low value. Input Range Low should correspond to Travel Range
Low, if the Zero Control Signal is configured as closed. If the Zero Control Signal is configured as open, Input Range
Low corresponds to Travel Range High. See figure 2‐1.
D Pressure Units—Defines the output and supply pressure units in either psi, bar, or kPa.
D LUI Pressure Units—Enter the pressure units displayed on the local user interface; psi, bar, or kPa.
D Temp Units—Degrees Fahrenheit or Celsius. The temperature measured is from a sensor mounted on the digital

Actuator and Valve Information
Field Communicator Setup & Diag > Detailed Setup > Actuator & Valve (1-2-5)
Follow the prompts on the Field Communicator to edit or view information in the following fields:
D Max Supply Press—Enter the maximum supply pressure in psi, bar, or kPa, depending on what was selected for
pressure units.
Note
If the actual measured pressure exceeds this setting by 25%, the Output A pressure measurement will not be displayed.
D 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.
D Valve Style—Enter the valve style, rotary or sliding-stem
D Zero Control Signal—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 current source to the instrument. The resulting valve travel is the Zero
Control Signal. (With direct-acting digital valve controllers, disconnecting the current source is the same as setting
the output pressure to zero.)
Setting Response
Field Communicator Setup & Diag > Detailed Setup > Response Control (1-2-6)
Follow the prompts on the Field Communicator to configure the following response control parameters:
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.
D 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 2‐4 lists the proportional gain, velocity gain, and minor loop feedback gain values for preselected tuning sets.

Minor Loop Feedback
Gain
D Damping Factor—If after selecting a tuning set the valve travel overshoot is excessive or unsatisfactory, the damping
factor allows you to either decrease damping to allow more overshoot, or increase damping to decrease the
overshoot.
D Expert Tuning Gains—With Expert Tuning, you can specify the proportional gain, velocity gain, and minor loop
feedback gain.
D Input Char—Defines the relationship between the travel target and ranged set point. Ranged set point is the input to
the characterization function. If the zero control signal equals closed, then a set point of 0% corresponds to a ranged
input of 0%. If the zero control signal equals open, a set point of 0% corresponds to a ranged input of 100%. Travel
target is the output from the characterization function.
You can select from the three fixed input characteristics shown in figure 2‐2 or you can select a custom
characteristic. Figure 2‐2 shows the relationship between the travel target and ranged set point for the fixed input
characteristics, assuming the Zero Control Signal is configured as closed.
You can specify 21 points on a custom characteristic curve. Each point defines a travel target, in % of ranged travel,
for a corresponding set point, in % of ranged set point. Set point values range from -6.25% to 106.25%. Before
modification, the custom characteristic is linear.
With input characterization you can modify the overall characteristic of the valve and instrument combination.
Selecting an equal percentage, quick opening, or custom (other than the default of linear) input characteristic
modifies the overall valve and instrument characteristic. However, if you select the linear input characteristic, the
overall valve and instrument characteristic is the characteristic of the valve, which is determined by the valve trim
(i.e., the plug or cage).
D Custom Char Table—To define a custom input characteristic, s
elect Custom Char Table. Select the point you wish to
define (1 to 21), then enter the desired set point value. Press Enter then enter the desired travel target for the
corresponding set point. When finished, select point 0 to return to the Response Control menu.

D Setpt Filter Time—Time constant for the set point filter, in seconds. The set point filter slows the response of the
digital valve controller and is typically used with noisy or fast processes. The filter provides improved closed loop
process control. To disable the filter, set the time constant to 0 seconds.
D Limits and Cutoff
Travel Limit Hi—Defines the high limit for the travel in percent (%) of ranged travel. It is the maximum allowable
travel (in percent of ranged travel) for the valve. During operation, the travel target will not exceed this limit. When
a Travel Limit High is set, the Travel Cutoff High is deactivated, since only one of these parameters can be active.
Travel Limit High is deactivated by setting it to 125.0%.

Travel Limit Lo—Defines the low limit for the travel in percent (%) of ranged travel. It is the minimum allowable travel
(in percent of ranged travel) for the valve. During operation, the travel target will not exceed this limit. When a
Travel Limit Low is set, the Travel Cutoff Low is deactivated, since only one of these parameters can be active. Travel
Limit Low is deactivated by setting it to -25.0%.
Travel Cutoff Hi—Defines the high cutoff point for the travel in percent (%) of ranged travel. Above this cutoff, the
travel target is set to 123.0% of the ranged travel. When a Travel Cutoff High is set, the Travel Limit High is
deactivated, since only one of these parameters can be active. Travel Cutoff High is deactivated by setting it to
125.0%.
Travel Cutoff Lo—Defines the low cutoff point for the travel. Travel Cutoff Low can be used to ensure proper seat load
is applied to the valve. When below the travel cutoff low, the output is set to zero or to full supply pressure,
depending upon the zero control signal. A Travel Cutoff Low of 0.5% is recommended to help ensure maximum
shutoff seat loading.
When a Travel Cutoff Low is set, the Travel Limit Low is deactivated, since only one of these parameters can be
active. Travel Cutoff Low is deactivated by setting it to -25.0%.
D Min Open/Close
Min Opening Time—Minimum Opening Time is configured in seconds and defines the minimum time for the travel to
increase the entire ranged travel. This rate is applied to any travel increases. A value of 0.0 seconds deactivates this
feature and allows the valve to stroke open as fast as possible. This parameter should be set to 0 in firmware 1, 2, 3,
and 4.
Min Closing Time—Minimum Closing Time is configured in seconds and defines the minimum time for the travel to
decrease the entire ranged travel. This rate is applied to any travel decreases. A value of 0.0 seconds deactivates this
feature and allows the valve to stroke closed as fast as possible. This parameter should be set to 0 in firmware 1, 2,
3, and 4.
D Integral Settings
Enab Int Control—Select Yes or No
Integral Gain—By setting this value to 0.0 the positioner integrator is disabled. Any other value will provide reset
action to improve static performance.
Integral Dead Zone—When the travel target and actual target deviate by less than this amount, the integrator is
automatically disabled. This prevents the positioner integrator from fighting with the process controller integrator
which may result in valve oscillation.
Setting Alerts
Field Communicator Setup & Diag > Detailed Setup > Alerts (1-2-7)
The following menus are available for configuring Alerts. Items on the menus may be changed with the instrument In
Service. Protection does not need to be removed (no need to set to None). Alerts are not processed when a Diagnostic
