Description
D103557X012
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.

Educational Services
For information on available courses for the DVC6200 SIS digital valve controller, as well as a variety of other products,
contact:
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.

HART Filter
Required?
NoNo
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

– 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:
Length(ft) = [160,000 - C
Length(m) = [160,000 - C
where:
160,000 = a constant derived for FIELDVUE instruments to ensure that the HART network RC time constant will be no
greater than 65 μs (per the HART specification).
C
C
= the capacitance of the control system or HART filter
master
= the capacitance of the cable used (see table 2‐1)
cable
The following example shows how to calculate the cable length for a Foxboro
of 50, 000 pF and a Belden 9501 cable with characteristic capacitance of 50pF/ft.
Length(ft) = [160,000 - 50,000pF] [50pF/ft]
Length = 2200 ft.
The HART communication cable length is limited by the cable characteristic capacitance. To increase cable length,
select a wire with lower capacitance per foot. Contact your Emerson sales office for specific information relating to
your control system.

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

Local Control Panel
Fisher LCP100 and LCP200 local control panels are used to manually open and close a safety shutdown valve.
The LCP100 provides a manual reset feature as well as a button for initiating a partial stroke test.
The LCP200 can be configured to auto or manual reset after a trip. It also offers a smart auto reset configuration which
requires a manual reset for locally initiated trips but auto reset for all other trips. It includes trip and reset push buttons
to provide a corresponding change in the state of the associated single pole double throw (SPDT) relay. The trip and
reset relays can be used as input to initiate Trip or Reset action in the logic solver. Additionally, it includes a button for
initiating a partial stroke test.
Installation
Both LCP100 and LCP200 local control panels have mounting holes for on‐site mounting of the device.
Notes
A mounting kit is available to use when replacing an LCP100 with the LCP200. Contact your Emerson sales office
obtaining this kit.
The local control panel must be installed so that the wiring connections are on the bottom to prevent accumulation of moisture
inside the box.
LCP100: When installing the LCP100 cover tighten the screws evenly in a criss‐cross pattern to a torque of 2.8 N•m (25 lbf•in) to
help ensure the cover is properly installed.
LCP200: When installing the terminal cover on the LCP200, use a 4 mm hex key to tighten the screws evenly in a criss‐cross pattern
to a torque of 8.7 N•m (77 lbf•in) +/- 10%, to help ensure the cover is properly installed. Apply silicone lubricant to the terminal
box O-ring.

Guided Setup
Device CommunicatorConfigure > Guided Setup (2‐1)
To quickly setup the instrument, the following procedures will guide you through the process.
Device Setup is used to configure the unique parameters for the valve, actuator, instrument and accessory
construction. After Device Setup is complete, proceed with Auto Calibration.
Auto Calibration is used to establish the limits of physical travel. During this process, the valve will fully stroke from
one travel extreme to the other. There are three calibration options to choose from:
d Autocalibrate – Standard runs the full calibration process (recommended).
d Autocalibrate – Without Biases establishes the travel end points, but does not adjust the Minor Loop Feedback
bias. This is for advanced use when manually setting the biases for large actuators.
dAdvanced Settings allows additional custom configuration of calibration parameters. This is for advanced use
when calibrating large actuators.
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.

Mode and Protection
Device CommunicatorConfigure > 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.
Follow the prompts on the Device 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 Device 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 provides a separate electronic label allowing for additional instrument identification.
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. For the Device 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.

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
DCalibration (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.
DAuxiliary 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.

Travel/Pressure Control
Device CommunicatorConfigure > Manual Setup > Travel/Pressure Control (2‐2-3)
End Point Pressure Control (EPPC)
DEPPC 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 the
EPPC Set Point. 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.
DEPPC 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.
DEPPC 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.
DEnd Point Pressure Control Tuning—These are the tuning parameters that the instrument uses while in end point
pressure control. The tuning set letters correspond with the travel control tuning sets (e.g. if tuning set C is
appropriate for travel control, it is also appropriate for pressure control). However, note that the individual values
may be different between travel and pressure control.
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.
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
DSP Rate Open is the 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.
DSP Rate Close is the 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.

DSet 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.
Travel Cutoffs
D Hi Cutoff Select—When selected the Travel Target is set to 123% when the Travel exceeds the Hi Cutoff Point.
D Hi Cutoff Point 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 Select—When selected the Travel Target is set to 23% when the Travel is below the Lo Cutoff Point.
D Lo Cutoff Point 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.
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.
DTravel 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.

DIntegral 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.
DIntegral 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.
DStabilize/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 DecreaseDamping 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.

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.
DFor 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,

Port A Pressure Limit
In single acting direct only applications, the instrument will limit the output pressure to the actuator from Port A.
When this pressure limit is exceeded the device will go to the no air state.
CAUTION
This is a firmware controlled feature that requires loop power to the instrument. If loop power is lost, or there is an
electronic or firmware failure, the protection feature will not remain in effect.
Output Pressure Limit Enable enables/disables the Port A Pressure Limit feature.
Note
There is an associated alert available with this feature. See the Port A Overpressurized alert in the Alert Setup section.
A partial stroke test is the process of taking the valve from the normal end to a target position at a preconfigured ramp
rate before returning to the normal end while gathering data. The data is analyzed to evaluate the condition of the
valve assembly against a set of user defined thresholds. A partial stroke test is only run if everything is normal in the
instrument. A safety demand signal will always take precedence over a partial stroke test.
Partial Stroke Test Parameters
Test Start Point defines the normal (not tripped) end of valve travel. The valve must be at this end for a PST to be
initiated. Setting this value to Not Configured will disable partial stroke tests.
Travel Hi Hi defines, in percent (%) of calibrated travel, the point above which the valve is considered to have reached
the high end.
Travel Lo Lo defines, in percent (%) of calibrated travel, the point below which the valve is considered to have reached
the low end.
Pause Time is the time between the outgoing and incoming strokes of the test. The default value is 5 seconds. Pause
Time will not be used if Short Duration PST is enabled. The outgoing stroke is from the normal end to the PST target
and the incoming stroke is the return stroke to normal. See figure 3‐3.

Low Friction Breakout Pressure indicates that the breakout required a lower force than configured by the user. Refer to
figure 3‐3.
Action On a Failed Test defines if the valve should step or ramp back on a failed stroke test.
Auto Test Interval is the interval of time in days between valve stroke tests that are automatically executed by the
digital valve controller, subject to the device being powered up. A value of 0 disables this feature.
Partial Stroke Parameters
Minimum Travel Movement is the percentage of total span that the valve moves away from its normal operating end
of travel towards its tripped end of travel during the test. The default value is 10%.
Short Duration PST, when enabled the incoming stroke is initiated as soon as the travel reaches the minimum travel
movement. Refer to figure 3‐4 for a time series representation of this parameter.

Outgoing Ramp Rate is the rate at which the valve will move during the Outgoing stroke of the Partial Stroke test. The
default value is 0.25%/second.
Incoming Ramp Rate is the rate at which the valve will move during the Incoming stroke of the Partial Stroke test. The
default value is 0.25%/second.
Return Lead defines the percent (%) change in setpoint to overcome the hysteresis in the valve assembly. The error
between setpoint and actual error is added to this percent change. For example, if the Return Lead is set at 0.5% and
there is a 1% error this will be set at 1.5%
Breakout Timeout is the user configured amount of time before which the valve must leave the normal end during a
PST.

Outgoing Pressure Threshold defines the actuator pressure at which a partial stroke test will abort during the outgoing
stroke (see figure 3‐3). This prevents the DVC6200 SIS from exhausting (or building) excessive pressure from/to the
actuator in an attempt to move a stuck valve. During PST Calibration, the Partial Stroke Outgoing Pressure Threshold
will be set automatically as follows:
dSingle Acting Actuators - For those actuators that exhaust pressure from the partial test start point, the Outgoing
Pressure Threshold will be a minimum value. For those actuators that build pressure from the partial test start point,
the Outgoing Pressure Threshold will be a maximum value.
dDouble Acting Actuators- The Outgoing Pressure Threshold 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.

To manually set the partial stroke Outgoing Pressure Threshold, 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 Partial Stroke Outgoing Pressure Limit by ensuring it is not selected as an evaluation criteria for PST
Abnormal.
3. Run a partial stroke test.
4. Select the Press/Time radio button on the partial stroke graph (refer to the example in figure 3‐5). 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 3‐7 to estimate the Outgoing Pressure Threshold.
5. Enable the previously disabled Outgoing Pressure Limit - calculate the value using table 3‐7.

Incoming Pressure Threshold defines the actuator pressure at which a partial stroke test will abort during the incoming
stroke (see figure 3‐3). This prevents the DVC6200 SIS from exhausting (or building) excessive pressure from / to the
actuator in an attempt to move a stuck valve.
PST Abnormal Criteria
A partial stroke test is marked as abnormal if it fails any of the following user-selected criteria.
1. Stroking Pressure (includes outgoing and incoming)
2. Hi friction breakout pressure
3. Low friction breakout pressure
4. Max travel
5. Insufficient travel
