The FIELDVUE DVC6200 SIS Digital Valve Controller is a core component of the PlantWeb™ digital
plant architecture. The digital valve controller powers PlantWeb by capturing and delivering valve
diagnostic data. Coupled with ValveLink™ software, the DVC6200 SIS provides users with an accurate
picture of valve performance, including actual stem position, instrument input signal, and pneumatic
pressure to the actuator. Using this information, the digital valve controller diagnoses not only itself,
but also the valve and actuator to which it is mounted.

Description
DVC6200 SIS digital valve controllers (figure 1‐1) are HART communicating, microprocessorbased
currenttopneumatic instruments. The DVC6200 SIS digital valve controller has three fundamental functions.
1. Modulate a pneumatic output to a valve actuator in response to a demand signal from a logic solver to move the
valve to a safe state.
2. Perform periodic tests on a valve assembly to exercise the mechanical components that are prone to sticking.
3. Continuously monitor the health of the valve and report alerts.

Logic Solver or Control System Requirements
There are several parameters that should be checked to ensure the logic solver or control system is compatible with
the DVC6200 SIS digital valve controller.
HART Filter / Line Conditioner
Depending on the logic solver or control system and operational mode of the DVC6200 SIS digital valve controller, a
line conditioner or HART filter may be required.

Line Conditioner
Required?
The HF340 HART filter and LC340 Line Conditioner are passive devices that are inserted in the field wiring of the HART
loop. A filter or line conditioner is normally installed near the field wiring terminals of the system I/O (see figure 2‐1).
Its purpose is to effectively isolate the system output from modulated HART communication signals and raise the
impedance of the system to allow HART communication. For more information, refer to the HF340 HART filter
(D102796X012) or LC340 Line Conditioner (D102797X012) instruction manual.
Voltage Available
The voltage available at the DVC6200 SIS digital valve controller must be at least 10 VDC. The voltage available at the
instrument is not the actual voltage measured at the instrument when the instrument is connected. The voltage
measured at the instrument is limited by the instrument and is typically less than the voltage available.
As shown in figure 2‐1, the voltage available at the instrument depends upon:
D The logic solver or control system compliance voltage
D if a line conditioner filter or intrinsic safety barrier is used, and
D the wire type and length.
The compliance voltage is the maximum voltage at the logic solver or control system output terminals at which the
system can produce maximum loop current.
The voltage available at the instrument may be calculated from the following equation:
Voltage Available = [Compliance Voltage (at maximum current)] - [line conditioner/filter voltage drop] - [total cable
resistance maximum current] - [barrier resistance x maximum current].
The calculated voltage available should be greater than or equal to 10 volts DC.

Example Calculation
18.5 volts (at 21.05 mA for Honeywell TDC2000)
– 2 volts
– Intrinsic safety barrier resistance (if used) x maximum loop current – 2.55 volts (121 ohms x 0.02105 amps)
– Total loop cable resistance x maximum loop current
= Voltage available at the instrument
2
– 1.01 volts (48 ohms x 0.02105 amps for
1000 feet of Belden 9501 cable)
= 15.49 volts, available—if safety barrier (2.55 volts)
is not used
NOTES:
Obtain filter voltage drop. The measured drop will be different than this value. The measured filter voltage drop
1
depends upon control system output voltage, the intrinsic safety barrier (if used), and the instrument. See note 2.
The voltage available at the instrument is not the voltage measured at the instrument terminals. Once the instrument is
2
connected, the instrument limits the measured voltage to approximately 8.0 to 9.5 volts.
Compliance Voltage
If the compliance voltage of the logic solver or control system is not known, perform the following compliance voltage
test.
1. Disconnect the field wiring from the system and connect equipment as shown in figure 2‐2 to the system terminals.

Maximum Cable Capacitance
The maximum cable length for HART communication is limited by the characteristic capacitance of the cable.
Maximum length due to capacitance can be calculated using the following formulas:

Auxiliary Terminal Wiring Length Guidelines
The Auxiliary Input Terminals of a DVC6200 SIS can be used with an LCP100 local control panel or a locally‐mounted
switch for initiating a partial stroke test. Some applications require that the switch or local control panel be installed
remotely from the DVC6200 SIS.
The length for wiring connected to the Auxiliary Input Terminals is limited by capacitance. For proper operation of the
Auxiliary Input Terminals capacitance should not exceed 100,000 pF. As with all control signal wiring, good wiring
practices should be observed to minimize adverse effect of electrical noise on the Aux Switch function.
Example Calculation: Capacitance per foot or per meter is required to calculate the length of wire that may be
connected to the Aux switch input. The wire should not exceed the capacitance limit of 100,000 pF. Typically the wire
manufacturer supplies a data sheet which provides all of the electrical properties of the wire. The pertinent parameter
is the highest possible capacitance. If shielded wire is used, the appropriate number is the “Conductor to Other
Conductor & Shield” value.
Example — 18AWG Unshielded Audio, Control and Instrumentation Cable
Manufacturer's specifications include:
Nom. Capacitance Conductor to Conductor @ 1 KHz: 26 pF/ft
Nom. Conductor DC Resistance @ 20 Deg. C: 5.96 Ohms/1000 ft
Max. Operating Voltage - UL 200 V RMS (PLTC, CMG),150 V RMS (ITC)
Allowable Length with this cable = 100,000pF /(26pF/ft) =3846 ft
Example — 18AWG Shielded Audio, Control and Instrumentation Cable
Manufacturer's specifications include:
Nom. Characteristic Impedance: 29 Ohms
Nom. Inductance: .15 μH/ft
Nom. Capacitance Conductor to Conductor @ 1 KHz: 51 pF/ft
Nom. Cap. Cond. to other Cond. & Shield @ 1 KHz 97 pF/ft
Allowable Length with this cable = 100,000pF /(97pF/ft) = 1030 ft
The AUX switch input passes less than 1 mA through the switch contacts, and uses less than 5 V, therefore, neither the
resistance nor the voltage rating of the cable are critical. Ensure that switch contact corrosion is prevented. It is
generally advisable that the switch have gold‐plated or sealed contacts.

Guided Setup
Field Communicator Configure > Guided Setup (2‐1)
To quickly setup the instrument, the following procedures will guide you through the process.
D Device Setup—This procedure is used to configure actuator and valve information, calibrate the valve assembly, and
assign the tuning set for the valve assembly.
D Performance Tuner—This procedure executes a simple step response test and then calculates a recommended set of
gain values based on the response of the control valve. See page 22 for additional information.
Manual Setup33
Manual Setup allows you to configure the digital valve controller to your application. Table 3‐1 lists the default settings
for a standard factory configuration. You can adjust actuator response, set the various modes, alerts, ranges, travel
cutoffs and limits. You can also restart the instrument and set the protection.
Refer to table 3‐2 for possible configurations for a digital valve controller operated by a 4‐20 mA input current
(point‐to‐point mode), and table 3‐3 for possible configurations for a digital valve controller operated by a 0‐24 VDC

Mode and Protection
Field Communicator Configure > Manual Setup > Mode and Protection (2‐2‐1)
Instrument Mode
There are two instrument modes for the DVC6200 SIS; In Service or Out of Service. In Service is the normal operating
mode such that the instrument follows the 420 mA or 24 VDC control signal. Out of Service is required in some cases
to modify configuration parameters or to run diagnostics.
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.
Write Protection
There are two Write Protection modes for the DVC6200 SIS: Not Protected or Protected. Protected prevents
configuration and calibration changes to the instrument. The default setting is Not Protected. Write Protection can be
changed to Protected remotely. However, to change Write Protection to Not Protected, you must have physical access
to the instrument. The procedure will require you to press a button ( ) on the terminal box as a security measure.
Instrument
Field Communicator Configure > Manual Setup > Instrument (2‐2‐2)
Follow the prompts on the Field Communicator display to configure the following Instrument parameters:
Identification
D HART Tag—A tag name up to 8 characters is available 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 HART Long Tag (HART Universal Revision 7 only)—A tag name up to 32 characters is available for the instrument.
D Description—Enter a description for the application with up to 16 characters. The description provides a longer
user‐defined electronic label to assist with more specific instrument identification than is available with the HART
tag.
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 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 63 for HART 7 and 0 and 15 for HART 5. To
change the polling address the instrument must be Out Of Service.
17
Configuration
April 2016
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.
Instruction Manual
D103557X012
Serial Numbers
D Instrument Serial Number—Enter the serial number on the instrument nameplate, up to 12 characters.
D Valve Serial Number—Enter the serial number for the valve in the application with up to 12 characters.
Units
D Pressure Units—Defines the output and supply pressure units in either psi, bar, kPa, or kg/cm2.
D Temperature Units—Degrees Fahrenheit or Celsius. The temperature measured is from a sensor mounted on the
digital valve controller's printed wiring board.
D Analog Input Units—Permits defining the Analog Input Units in mA or percent of 4-20 mA range.
Terminal Box
D Calibration (CAL) Button—This button is near the wiring terminals in the terminal box and provides a quick means to
autocalibrate the instrument. The button must be pressed for 3 to 10 seconds. Autocalibration will move the valve
through the full range of travel whether the Instrument Mode is In Service or Out of Service. However, if the Write
Protection is Protected, this button will not be active. To abort, press the button again for 1 second. The calibration
button is disabled by default.
D Auxiliary Terminal Action—These wire terminals can be configured to initiate a partial stroke test upon detection of
a short across the (+) and (-) terminals. The terminals must be shorted for 3 to 10 seconds. Alternatively, the
auxiliary terminals can be configured to support the local control panel.
Spec Sheet
The Spec Sheet provides a means to store the entire control valve specifications on board the DVC6200 SIS.
Edit Instrument Time
Permits setting the instrument clock. When alerts are stored in the alert record, the record includes the time and date.
The instrument clock uses a 24‐hour format.

Travel/Pressure Control
Field Communicator Configure > Manual Setup > Travel/Pressure Control (2‐2-3)
End Point Pressure Control (EPPC)
D EPPC Enable—Select Yes or No. End Point Pressure Control allows the digital valve controller to pull back from
saturation of the pneumatic output after reaching the travel extreme. Rather than having the instrument provide
full supply pressure (saturation) continuously at the travel extreme, the digital valve controller switches to an End
Point Pressure Control where the output pressure (pressure controller set point) to the actuator is maintained at a
certain value. This value is configured through the Upper Operating Pressure feature. Because the digital valve
controller is constantly in control and not allowed to reach a dormant or saturated state, it is constantly testing its
own pneumatic system. If there is an output pressure deviation, for example, the instrument will issue an alert. To
ensure there is an alert when an output pressure deviation occurs, setup the alert as described under Pressure
Deviation Alert.
D EPPC Set Point—Used in conjunction with End Point Pressure Control, End Point Pressure Control Set Point allows
the user to select a pressure to be delivered by the instrument at the travel extreme. For a fail‐closed valve, this
pressure must be sufficient to maintain the fully open position. For a fail‐open valve, this pressure (which is
automatically set to supply pressure) must be sufficient to fully close the valve and maintain its rated shutoff
classification. For double‐acting spring return actuators, this is the differential pressure required to either maintain
the fully open or fully closed position, depending on the valve and actuator configuration. For a double‐acting
actuator without springs with a fail‐close valve, this is 95% of the supply pressure. If the valve is fail‐open, the upper
operating pressure for all actuator is set to the supply pressure.
D EPPC Saturation Time—End Point Pressure Control Saturation Time is the time the digital valve controller stays in
hard cutoff before switching to pressure control. Default is 45 seconds.
Characterization
D Input Characterization
Input Characterization defines the relationship between the travel target and ranged set point. Ranged set point is the
input to the characterization function. If the zero power condition equals closed, then a set point of 0% corresponds to
a ranged input of 0%. If the zero power condition equals open, a set point of 0% corresponds to a ranged input of 100%.
Travel target is the output from the characterization function.
To select an input characterization, select Input Characterization from the Characterization menu. You can select from
the three fixed input characteristics shown in figure 3‐1 or you can select a custom characteristic. Figure 3‐1 shows the
relationship between the travel target and ranged set point for the fixed input characteristics, assuming the Zero
Power Condition 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.
D Custom Characterization
To define a custom input character, from the Characterization menu select Custom Characterization. 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 Characterization menu.
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).

Dynamic Response
D SP Rate Open—Maximum rate (% of valve travel per second) at which the digital valve controller will move to the
open position regardless of the rate of input current change. A value of 0 will deactivate this feature and allow the
valve to stroke open as fast as possible. In firmware 4 this parameter should be set to 0.
D SP Rate Close—Maximum rate (% of valve travel per second) at which the digital valve controller will move to the
close position regardless of the rate of input current change. A value of 0 will deactivate this feature and allow the
valve to stroke close as fast as possible. In firmware 4 this parameter should be set to 0.
D Set Point Filter Time (Lag Time)—The Set Point Filter Time (Lag Time) slows the response of the digital valve
controller. A value ranging from 0.2 to 10.0 can be used for noisy or fast processes to improve closed loop process
control. Entering a value of 0.0 will deactivate the lag filter. In firmware 4 this parameter should be set to 0.
Travel Cutoffs
D Hi Cutoff Point—This is the point within the calibrated travel range above which the cutoff is in effect. When using
cutoffs, a Cutoff Hi of 50% is recommended to ensure valve goes fully open.
D Lo Cutoff Point—This is the point within the calibrated travel range below which the cutoff is in effect. When using
cutoffs, a Cutoff Lo of 50% is recommended to help ensure maximum shutoff seat loading.

Travel Tuning
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 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 3‐4 lists the proportional gain, velocity gain and minor loop feedback gain values for preselected tuning sets.

In addition, you can specify Expert tuning and individually set the proportional gain, velocity gain, and minor loop
feedback gain. Individually setting or changing any tuning parameter or running the Performance Tuner or
Stabilize/Optimize routine will automatically change the tuning set to X (expert).
Note
Use Expert tuning only if standard tuning has not achieved the desired results.
Stabilize/Optimize or Performance Tuner may be used to achieve the desired results more rapidly than manual Expert tuning.
Table 3‐5 provides tuning set selection guidelines for Fisher and Baumann actuators. These tuning sets are only
recommended starting points. After you finish setting up and calibrating the instrument, you may have to select either
a higher or lower tuning set to get the desired response. You can use the Performance Tuner to optimize tuning.
D Proportional Gain—the proportional gain for the travel control tuning set. Changing this parameter will also change
the tuning set to Expert.
D Velocity Gain—the velocity gain for the travel control tuning set. Changing this parameter will also change the
tuning set to Expert.
D MLFB Gain—the minor loop feedback gain for the travel control tuning set. Changing this parameter will also change
the tuning set to Expert.
D Integral Enable—Yes or No. Enable the integral setting to improve static performance by correcting for error that
exists between the travel target and actual travel. Travel Integral Control is enabled by default.
D Integral Gain—Travel Integral Gain is the ratio of the change in output to the change in input, based on the control
action in which the output is proportional to the time integral of the input.
D Performance Tuner
WARNING
During performance tuning the valve may move, causing process fluid or pressure to be released. To avoid personal injury
and property damage caused by the release of process fluid or pressure, isolate the valve from the process and equalize
pressure on both sides of the valve or bleed off the process fluid.
The Performance Tuner is used to determine digital valve controller tuning. It can be used with digital valve controllers
mounted on most sliding‐stem and rotary actuators, including Fisher and other manufacturers' products. Moreover,
because the performance tuner can detect internal instabilities before they become apparent in the travel response, it
can generally optimize tuning more effectively than manual tuning. Typically, the performance tuner takes 3 to 5
minutes to tune an instrument, although tuning instruments mounted on larger actuators may take longer.

D Stabilize/Optimize
WARNING
During Stabilize/Optimize the valve may move, causing process fluid or pressure to be released. To avoid personal injury
and property damage caused by the release of process fluid or pressure, isolate the valve from the process and equalize
pressure on both sides of the valve or bleed off the process fluid.
Stabilize/Optimize permits you to adjust valve response by changing the digital valve controller tuning. During this
routine, the instrument must be out of service; however, the instrument will respond to setpoint changes.
If the valve is unstable, select Decrease Response to stabilize valve operation. This selects the next lower tuning set
(e.g., F to E). If the valve response is sluggish, select Increase Response to make the valve more responsive. This selects
the next higher tuning set (e.g., F to G).
If after selecting Decrease Response or Increase Response the valve travel overshoot is excessive, select Decrease
Damping to select a damping value that allows more overshoot. Select Increase Damping to select a damping value that
will decrease the overshoot. When finished, select done.
Integral Settings
D Integral Dead Zone—A window around the Primary Setpoint in which integral action is disabled. This feature is used
to eliminate friction induced limit cycles around the Primary Setpoint when the integrator is active. The Dead Zone
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.

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 SIS housing) has to remain within this range throughout the entire valve travel. The linear magnet
assemblies are symmetrical. Either end may be up.

Travel Sensor Motion
WARNING
If you answer YES to the prompt for permission to move the valve when determining travel sensor motion, the instrument
will move the valve through a significant portion of its travel range. To avoid personal injury and property damage caused
by the release of process fluid or pressure, isolate the valve from the process and equalize pressure on both sides of the
valve or bleed off the process fluid.

Select Clockwise/Toward Bottom, or Counterclockwise/Toward Top. Travel Sensor Motion establishes the proper
travel sensor rotation. 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.
D For instruments with Relay A and C: If increasing air pressure at output A causes the magnet assembly to move
down or the rotary shaft to turn clockwise, enter CW/To Bottom Inst. If it causes the magnet assembly to move up,
or the rotary shaft to turn counterclockwise, enter CCW/To Top Inst.
D For instruments with Relay B: If decreasing air pressure at output B causes the magnet assembly to down, or the
rotary shaft to turn clockwise, enter CW/To Bottom Inst. If it causes the magnet assembly to move up, or the rotary
shaft to turn counterclockwise, enter CCW/To Top Inst.
Maximum Supply Pressure
Enter the maximum supply pressure that is required to fully stroke the valve.

SIS/Partial Stroke Test
Field Communicator Configure > Manual Setup > SIS/Partial Stroke (2-2-6)
Partial Stroke Test (PST)
D PST Pressure Limit— This defines the actuator pressure at which a partial stroke test will abort. This prevents the
DVC6200 SIS from exhausting (or building) excessive pressure to the actuator in an attempt to move a stuck valve.
During Device Setup or Auto Travel Calibration, the Partial Stroke Pressure Limit will be set automatically as follows:
Single Acting Actuators - For those actuators that exhaust pressure from the partial test start point, the Pressure
Limit will be a minimum value. For those actuators that build pressure from the partial test start point, the Pressure
Limit will be a maximum value.
Double Acting Actuators - The Pressure Limit will be set to a negative value for actuators where the partial stroke
start point is opposite of the Zero Power Condition (e.g., Partial Stroke Start Point = Open and Zero Power
Condition = Closed) and to a positive valve for actuators where the partial stroke start point is the same as the Zero
Power Condition.
The pressure signal used to determine this parameter depends on relay type and is summarized below.
Relay Type Pressure Signal

B Port B - Port A

C Special App. Port A
To manually set the partial stroke pressure limit, you must examine current partial stroke test results using ValveLink
software. The following steps will guide you through the process:
1. Connect the DVC6200 SIS to a system running ValveLink software.
2. Disable the following parameters:
D Travel Deviation Alert - set to 125%.
D End Point Pressure Control - disable
D Partial Stroke Pressure Limit - disable by setting the appropriate value shown in table 3‐7.

3. Run a partial stroke test.
4. Select the Press/Time radio button on the partial stroke graph (refer to the example in figure 3‐3, bottom plot). If
the actuator pressure starts high and moves low, find the minimum actuator pressure (Pmin). If the actuator
pressure starts low and moves high, find the maximum actuator pressure (Pmax). Doubleacting actuators will
display differential pressure. Use table 3‐8 to estimate the partial stroke pressure limit.

5. Enable the parameters that were previously disabled:
D Travel Deviation Alert - set to 1.5x the maximum travel deviation between travel set point and travel.
D End Point Pressure Control - enable
D Partial Stroke Pressure Limit - calculate the value using table 3‐8.
PST Enable—Yes or No. This enables or disables the Partial Stroke Test.
PST Start Point—Valve Open or Valve Closed. This defines the travel stop that the valve needs to be at before a partial
stroke test can be initiated. This also defines the travel stop for end point pressure control. Setting this value to Not
Configured will disable partial stroke tests and end point pressure control.
PST Variables—Follow the prompts on the Field Communicator display to enter or view information for following PST
Variables:
D Max Travel Movement— This is the percentage of total span that the valve moves away from its normal operating
state towards its tripped state during the test. The default value is 10%.
D Test Speed—This is the rate at which the valve will move during the test. The default value is 0.25%/second.
D Pause Time—This is the pause time between the up and down strokes of the test. The default value is 5 seconds.

SIS Options
D Auto Test Interval—This is the interval of time (in days) between partial stroke tests that are automatically run by the
digital valve controller, subject to the device being powered up. A value of 0 disables this feature.
D LoopInitiated PST—When this feature is enabled, the digital valve controller will run a partial stroke test if the loop
current is set to within +/0.5% of the PST trip point. The loop current must remain at that point for the duration of
the test. To abort the test, the loop current must be returned to the normal or tripped current. This feature is
disabled by default. This feature is not available when a looppowered local control panel is installed.
PST Trip Point (ETT) - This is the point at which the loop current must be set to run a partial stroke test for
energizetotrip applications. This value is not configurable.
PST Trip Point (DETT) - This is the point at which the loop current must be set to run a partial stroke test for
deenergizetotrip applications. This value is not configurable.
D Device Power Up Reset—This defines the power up behavior of the DVC6200 SIS. Auto Reset allows the valve to
track the command signal when power is applied to the device. Manual Reset will lock the device in its safety
position until the digital valve controller is reset.
If Manual Reset is selected, its state can be determined from the status monitor by monitoring the Locked In Safety
Position alert.
When Auxiliary Terminal Action is set to SIS Local Control Panel, Device Power Up is set to Manual Reset and cannot
be changed to Auto Reset.
The reset signal depends on how the AUX terminals are configured. If configured for SIS Local Control Panel, the
digital valve controller can be reset by pressing the button next to the green light on the LCP100. If configured as
Push Button Partial Stroke, the digital valve controller can be reset by shorting the AUX terminals for more than 3
seconds but less than 10 seconds. The device cannot be reset from the AUX terminals if they are configured
otherwise.
D Action on Failed Test—This displays the action taken by the instrument if a communication timeout occurs. Values
are Ramp Back or Step Back.
Outputs

Output Terminal Configuration
D Output Terminal Enable—If using the output terminal for a Position Transmitter or Switch output, this must be
Enabled.
D Function—The output terminals can be configured as one of the following:
Transmitter - 420 mA output that represents 0100% of the calibrated valve travel.
Limit Switch - Discrete switch (1A max) that trips at a configurable point within 0100% of calibrated valve travel.
Alert Switch - Discrete switch (1A max) that trips based on a configurable device alert.
D Fail Signal—Should the output circuit fail to operate properly; the output will attempt to drive to a known state.
Depending on the nature of the failure, the circuit may or may not be able to achieve this fail state. When
