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.

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

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.
Relay TypePressure Signal

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.

SIS Options
DLoopInitiated 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 local control panel is installed.
dPST Trip Point (ETT) 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 and is preset at 8 mA.
dPST Trip Point (DETT) 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 and is preset at 16 mA.
DLatch on Position Trip— The device will take the output to the trip state if the loop current is normal and the travel
crosses the threshold towards the trip end. The position latch reset is always manual reset. The latch can be cleared
by using one of the the user interfaces, a local control panel, or recycling power to the device. Select enable or
disable.
Note
The condition that caused the valve to drift toward the trip end must be corrected before the manual reset is done. For example, if
supply pressure droop caused the drift, the supply pressure must be restored before the manual reset is performed.
d Position Trip Point is defined as a % of travel from the trip end.
D Change Reset Mode defines the latching behavior of the DVC6200 SIS after a trip has occurred. There are three
choices available.
d Auto Reset— The valve will follow the loop signal from the logic solver and will not latch in the tripped position.
d Manual Reset— The valve will latch in the tripped position until the loop signal from the logic solver is at the
normal state and
switch wired to the AUX terminals, or from a HART command through the user interface.
dSmart Auto Reset— The valve will latch in the tripped position until the originating source that tripped the valve
provides a reset signal. If the logic solver trips the valve, and the local control panel trip button is not pressed,
then the logic solver can return the valve to the normal position. However, if the local control panel trip button
is pressed, then the local control panel is required to reset the valve to the normal position. (Note that the local
control panel can issue a “pre-approval” if the reset button is pressed while the logic solver is still tripped. When
the logic solver attempts to return the valve to the normal state, the DVC6200 SIS will follow.)

are Ramp Back or Step Back.
the DVC6200 SIS is reset. The reset signal can be initiated by a Local Control Panel, discrete
Solenoid Valve Test
The DVC6200 SIS can be used to test and evaluate the operation of an external solenoid valve (SOV). This is
accomplished by briefly removing power to the solenoid valve and examining the resulting pressure drop across the
solenoid valve.
32
Instruction Manual
D103557X012
Configuration
February 2021
If the solenoid valve is connected directly to a logic solver, then the DVC6200 SIS can be used to monitor the pressures
while the logic solver momentarily trips the solenoid valve. ValveLink Software can gather the data and provide a
graphical representation of the actuator pressure and valve travel. Refer to the Monitoring Health of External Solenoid
Valve (SOV) with FIELDVUE DVC6200 SIS Digital Valve Controllers Instruction Manual Supplement (D104028X012
) for
further details.
If the solenoid valve is wired in series with the DVC6200 SIS and logic solver, then the DVC6200 SIS can be used to
initiate the momentary trip. For instructions on the physical pneumatic and electrical connections refer to the Quick
Start Guide (D103556X012
).
Instrument Configuration to Support SOV Testing
DRelay Type— Select the appropriate relay (B or C) with the “special app” designation. Special app refers to the
additional tubing (monitoring line) that is installed between the unused output port of the DVC6200 SIS and a
connection downstream of the solenoid valve, close to the actuator.
DOutput Terminal Function— Since the solenoid valve is wired through the output terminals of the DVC6200 SIS, the
terminals must be enabled and configured as “SOV Test”. Note that the Transmitter/Switch selection on the printed
wiring board (PWB) must also be set to “Switch”.
SOV Test Parameters (see figure 3‐6)
DPulse Duration is the length of time of the momentary power disruption to the solenoid valve. It should be long
enough to detect a Trip Pressure Differential, but short enough to not cause the SIS valve to move. This is
automatically determined during the SOV Test Calibration routine.
DMonitoring Time is the length of time from the start of the test (pulse initiation), to the end of the data gathering. It
should be long enough to allow the Reset Pressure Differential to stabilize.
DTrip Pressure Differential— During the momentary solenoid valve trip, the pressure drop across the solenoid valve is
measured. This value is the maximum pressure drop recorded during the SOV test. It is determined automatically
during the SOV Test Calibration routine.

DReset Pressure Differential— After the solenoid valve is momentarily tripped, the pressure differential across the
solenoid valve should reduce back to zero. However, depending on the Monitoring Time, the downstream pressure
may not fully recover at the end of the test. This value is automatically determined during the SOV Test Calibration
routine.
D SOV Test before PST configures the device to always run a SOV test prior to a PST test any time a PST is initiated.
D On Abnormal SOV Test — If SOV Test before PST is configured, this determines the behavior if the SOV test result is
abnormal. The configuration choices are to continue on to the PST, or cancel the PST.
DIndependent SOV Test configures the device to allow a SOV Test to be run independent of a PST test.

DTrip Pressure Alert Point— During an SOV Test, if the trip pressure differential is lower than this value, the alert will
be active.
DReset Pressure Alert Point— During an SOV Test, if the reset pressure differential exceeds this value, the alert will be
DOutput Terminal Enable—If using the output terminal for a Position Transmitter or Switch Output, or for Solenoid
Valve Testing, 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.
SOV Test – Normally closed discrete switch that momentarily opens during a solenoid valve test.
DFail 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
configured as a position transmitter, the output can be configured to fail low (< 3.6 mA). The output can be
configured to fail high (> 22.5 mA) when the digital valve controller is powered. When configured as a switch, the
output can be configured to drive Closed or Open.
Note
On loss of digital valve controller power, the switch circuit will always go to the open state.

HART Variable Assignments
Instrument variables can be reported via four different HART variable assignments. The Primary Variable is always
configured as Analog Input. However, the remaining three variables have additional options as listed below.
This configures the relationship between the valve travel and the position transmitter output signal. There are two
choices; 4mA = Valve Closed or 4mA = Valve Open.
Burst Mode
Burst mode provides continuous communication from the digital valve controller. Burst mode applies only to the
transmission of burst mode data (HART Variable Assignments) and does not affect the way other data is accessed.
D Burst Enable—This turns on or off the burst mode.
D Burst Command—This defines which HART command is configured for burst reporting.When using a TriLoop,

Notes
Access to information in the instrument is normally obtained through the poll/response of HART communication. The Device
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 Device 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.
Burst mode will be automatically disabled during diagnostics tests such as Valve Signature.
HART 7 allows three burst commands to be reported. When using a Tri-Loop, do not enable the 2nd or 3rd burst commands. These
additional commands will result in missed messages, thus taking the Tri-Loop's output to the fault state.

Alert Setup
Device CommunicatorConfigure > Alert Setup (2‐3)
An alert is a notification that the instrument has detected a problem. Alerts that are enabled and active will be
recorded in the instrument memory within the Alert Record (see Section 5). Some alerts are also defined in the
HART Command 48 response structure which is can be read by any HART communicating host system (refer to
the DVC6200 SIS HART Field Device Specification, D103638X012
).
Certain critical alerts can be configured to shut down the device when active (i.e. latch in the Zero Power Condition).
This can be enabled or disabled for each applicable alert. The default shutdown setting is disabled. To clear the
shutdown, correct the problem and then cycle power to the instrument (or disable the alert).
Alerts may be enabled or disabled with the instrument In Service, Out of Service, Protection On, or Protection Off.
However, shutdown alerts can only be enabled or disabled while Protection is off.
For a detailed explanation of the alerts and the recommended actions, refer to Section 5.

Calibration Overview
When a DVC6200 SIS digital valve controller is ordered as part of a control valve assembly, the factory mounts the
digital valve controller on the actuator and connects the necessary tubing, then sets up and calibrates the controller.
For digital valve controllers that are ordered separately, recalibration of the analog input or pressure sensors generally
is unnecessary. However, after mounting on an actuator, perform the initial setup then calibrate travel by selecting

Note
The Instrument Mode must be Out Of Service and the Protection set to None before the instrument can be calibrated.
If you are operating in burst mode, we recommend that you disable burst before continuing with calibration. Once calibration is
complete, burst mode may then be turned back on.
WARNING
During calibration the valve will move full stroke. To avoid personal injury and property damage caused by the release of
pressure or process fluid, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the

Travel Calibration
If a double‐acting relay is used, you will be prompted to run the relay adjustment when auto or manual calibration is
selected. Select Yes to adjust the relay, select No to proceed with calibration. For additional information, refer to Relay
Adjustment on page 43.
Auto Calibration
1. The auto calibration procedure is automatic. It is completed when the Calibration menu appears.
During calibration, the instrument seeks the high and low end points and the minor loop feedback (MLFB) and output
bias. By searching for the end points, the instrument establishes the limits of physical travel, i.e. the actual travel 0 and
100% positions. This also determines how far the relay beam swings to calibrate the sensitivity of the MLFB sensor.
2. Place the instrument In Service and verify that the travel properly tracks the current source.
If the unit does not calibrate, refer to table 4‐1 for error messages and possible remedies.

Pushbutton Calibration
A pushbutton near the wiring terminals in the terminal box 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. To
enable it, go to Manual Setup > Instrument > Calibration Button.
Note
The autocal pushbutton will not be active if the instrument is Locked in Safety.
This calibration procedure is recommended whenever the I/P converter or pneumatic relay is replaced. Do not use the
pushbutton calibration for initial calibration when mounting the instrument on an actuator, or if the printed wiring
board assembly was replaced.
If you suspect calibration has changed due to drift, first perform a Valve Signature diagnostic test using ValveLink
software to capture the asfound data for future root cause analysis.

Relay Adjustment
Before beginning travel calibration, check the relay adjustment. Replace the digital valve controller cover when
finished.
Note
Relay B and C are not user‐adjustable.
Double‐Acting Relay
The double‐acting relay is designated by “Relay A” on a label affixed to the relay itself. For double‐acting actuators, the
valve must be near mid‐travel to properly adjust the relay. The Device Communicator will automatically position the
valve when Relay Adjust is selected.
Rotate the adjustment disc, shown in figure 4‐1, until the output pressure displayed on the Device Communicator is
between 50 and 70% of supply pressure. This adjustment is very sensitive. Be sure to allow the pressure reading to
stabilize before making another adjustment (stabilization may take up to 30 seconds or more for large actuators).
Low bleed relay stabilization may take approximately two minutes longer than the standard relay.

PST Calibration
This procedure permits you to run the Partial Stroke Calibration, which enables the Partial Stroke Test. It establishes
values for Partial Stroke Pressure Limit, Pressure Set Point and Pressure Saturation Time for End Point Pressure Control,
Travel Deviation Alert Point and Travel Deviation Time. The Partial Stroke Calibration also sets default values for max
travel movement, test speed, and test pause time.
Note
You must take the instrument out of service before running Partial Stroke Calibration.
Ensure that the instrument is put back in service after the completing the calibration procedure.
SOV Test Calibration
This procedure is used when a solenoid valve is wired to the Output terminals. During this routine, the output terminal
circuit is interrupted momentarily to trip the solenoid. During the test, the Trip Pressure Differential, Recovery
Pressure Differential, and Valve Travel are monitored. The test attempts to find the optimal trip duration which results
in a measurable pressure drop across the solenoid, but no valve travel movement. If the proper duration cannot be
established within 10 tries, the test will stop.

Port A Overpressurized requires that both the Port A Overpressurized Alert and the Port A Output Pressure Limit are
enabled and applies to single acting direct applications only. The alert is active if the output pressure from Port A of the
DVC6200 SIS exceeds the configured pressure limit setting. Check the supply pressure regulator for damage and verify
its pressure set point.
Pressure Fallback Active is active when the instrument has detected a problem with the travel feedback and is now
controlling the output like an I/P transducer.
Pressure Sensor Failure is active if any of the 3 pressure sensor readings (output A, output B, supply) are outside the
range of 24.0 to 125.0% of the calibrated pressure for more than 60 seconds. If this alert is active, check the
instrument supply pressure, ensure the printed wiring board assembly is properly mounted onto the module base
assembly, and ensure the pressure sensor o-rings are properly installed. If the alert persists after restarting the
instrument, replace the printed wiring board assembly.
PST Abnormal indicates that a partial stroke test has failed. The criteria for determining an abnormal partial stroke test
is user configurable. See page 30 for PST Abnormal Criteria.
CAUTION
If a PST Abnormal alert is active, there may be potential energy stored in the valve and actuator assembly. Sudden release
of this energy may cause the valve to suddenly open or close, resulting in equipment damage.
PST Prohibited indicates that a partial stroke test was initiated, but then aborted due to abnormal conditions. The
criteria for prohibiting a partial stroke test is user configurable. See page 31 for PST Prohibited critera.
PST Pass indicates that a partial stroke test has completed normally. This alert will automatically clear. The timeout
setting for the alert shares the same configuration setting as the Tripped by LCP Alert Latch.
Reference Voltage Failure is active if there is a failure associated with the internal voltage reference. If this alert is
active, replace the printed wiring board assembly.
SIS Hardware Failure is active if a demand has occurred, but the electronics hardware failed to take control of the I/P
drive.
Manual Reset Required indicates that the DVC6200 SIS is in the tripped position. In order for the instrument to follow
the loop signal, it must be reset by pressing the Green button on the LCP, or perform a Reset Latch with the host.
SIS Program Flow Failure is active if the firmware is not performing the expected series of calculations.
SIS Stroke Performance— If the DVC6200 SIS is tripped to the safety position and/or returns to the normal position, the
instrument will record the demand and/or return stroke time, demand break out time, and the calendar time that
these events happened. This alert is active if any of the configured thresholds are exceeded.
Supply Pressure High is active if the supply pressure falls above the supply pressure high alert point.
Supply Pressure Low is active if the supply pressure falls below the supply pressure low alert point.
Temperature Sensor Failure is active when the instrument temperature sensor fails, or the sensor reading is outside of
the range of -60 to 100°C (-76 to 212°F). The temperature reading is used internally for temperature compensation of
inputs. If this alert is active, restart the instrument. If the alert persists, replace the printed wiring board assembly.
Travel Accumulator High is active if the Travel Accumulator exceeds the Travel Accumulator Alert Point. The Travel
Accumulator totalizes the travel of the valve when the deadband is exceeded. To clear the alert, set the Travel
Accumulator to a value less than the alert point. See figure 5‐2.

Travel Alert Hi is active when the Travel exceeds the Travel Alert Hi Point. Once the alert is active, the alert will clear
when the Travel falls below the Travel Alert Hi Point minus the Travel Alert Deadband. See figure 5‐1.
Note
The Travel Alert Hi Hi and Travel Alert Lo Lo points are used to calculate the stroke time in the event of a demand. The values are
typically set to 99% and 1% respectively, however it is not necessary to enable the alert. Stroke time can be read from the device
with ValveLink software.
Travel Alert Hi-Hi is active when the Travel exceeds the Travel Alert Hi Hi Point. Once the alert is active, the alert will
clear when the Travel falls below the Travel Alert Hi Hi Point minus the Travel Alert Deadband. See figure 5‐1.
Travel Alert Lo is active when the Travel is below the Travel Alert Lo Point. Once the alert is active, the alert will clear
when the Travel exceeds the Travel Alert Lo Point plus the Travel Alert Deadband. See figure 5‐1.
Travel Alert Lo-Lo is active when the Travel is below the Travel Alert Lo Point. Once the alert is active, the alert will clear
when the Travel exceeds the Travel Alert Lo Point plus the Travel Alert Deadband. See figure 5‐1.
Travel Cutoff Hi is active when the Travel exceeds the Hi Cutoff Point.
Travel Cutoff Lo is active when the Travel falls below the Lo Cutoff Point.
Travel Deviation— If the difference between the Travel Target and the Travel exceeds the Travel Deviation Alert Point
for more than the Travel Deviation Time, the Travel Deviation Alert is active. It remains active until the difference
between the travel target and the Travel is less than the Travel Deviation Alert Point minus the Travel Alert Deadband.
See figure 5‐1.
Travel Sensor Failure is active if the sensed travel is outside the range of 25.0 to 125.0% of calibrated travel. If this alert
is active, check the instrument mounting. Also, check that the electrical connection from the travel sensor is properly
plugged into the printed wiring board assembly. After restarting the instrument, if the alert persists, troubleshoot the
printed wiring board assembly or travel sensor.
Tripped by the LCP indicates that the DVC6200 SIS is in the tripped position as a result of someone pressing the trip
button on the local control panel. This alert will automatically clear only after the valve returns to the normal state and
the Tripped by LCP Alert Latch timeout has expired.
Variable out of Range is active if one or more of the measured analog sensor readings (loop current, pressure,
temperature, or travel) is saturated or reading out of its configured range. The condition may be due to improper
configuration or physical setup and not be due to a sensor malfunction.
Deadband Principle of Operation
The deadband is the percent (%) of ranged travel around a travel reference point where no change in alert status will
occur. This prevents the alert from toggling on and off when operating near the alert point.
The Travel Alert Deadband applies to the Travel Deviation Alert as well as the Travel Alert Hi, Lo, Hi Hi, and Lo Lo.
Figure 5‐1 illustrates the principle behind setting and clearing a Travel Alert Hi. The alert is set when the travel exceeds
the alert point, and is cleared when it falls below the deadband.

gets reestablished to the point of travel reversal that occurs outside of the deadband. The deadband must be
exceeded before a change in travel direction will be counted as a cycle and the accumulated travel (up to the point of
travel reversal) is added to the total accumulation. See figure 5‐2.

WARNING
During stroke valve, partial stroke, and demand mode tests the valve will move. To avoid personal injury and property
damage caused by the release of pressure or process fluid, when used in an application where the valve is normally closed,
provide some temporary means of control for the process.
Stroke Valve
Follow the prompts on the Device Communicator display to select from the following:
D Done—Select this if you are done. All ramping is stopped when DONE is selected.
D Ramp Open—ramps the travel toward open at the rate of 1.0% per second of the ranged travel.
D Ramp Closed—ramps the travel toward closed at the rate of 1.0% per second of the ranged travel.
D Ramp to Target—ramps the travel to the specified target at the rate of 1.0% per second of the ranged travel.
D Step to Target—steps the travel to the specified target.
Partial Stroke Test
There are multiple ways that a partial stroke test can be initiated with the DVC6200 SIS.
DAutomatic (Scheduled)
The Auto Partial Stroke Test allows the partial stroke test to be scheduled by the DVC6200 SIS. The test is scheduled in
number of hours between tests. Any power cycle will reset the test clock timer.
DLocal Pushbutton
A partial stroke test command may be sent to the digital valve controller using a set of contacts wired to the auxiliary
+/- terminals. To perform a test, the contacts must be closed for 3 to 10 seconds and then opened. To abort the test,
close the contacts for 1 second. The last set of diagnostic data is stored in the instrument memory for later retrieval via
ValveLink software.
DLocal Control Panel
The LCP100 or LPC200 local control panel is wired directly to the DVC6200 SIS digital valve controller.
The “Valve Test” push button (see figure 5‐3) allows the valve to perform the configured partial stroke test.
- Press and hold for 3 to 10 seconds
The test can be overridden by the “Valve Close” button, “Valve Open” button, or if an emergency demand occurs.

Solenoid Valve Health Monitoring
Solenoid valve health monitoring requires the following setup:
D Single-acting actuator
D Solenoid valve installed between the DVC6200 SIS pressure output and the actuator
D Unused output pressure port of the DVC6200 SIS connected between the solenoid and the actuator, close to the
actuator
D Relay configured as “special application”
D Output terminal configured as “Limit Switch” (only required when the solenoid valve is wired in series with the
DVC6200 SIS)
If the solenoid valve is wired directly to the logic solver, the following steps can be used to test the solenoid valve.
1. Momentarily interrupt the power to the solenoid valve through the Logic Solver (typically 100 to 200 milliseconds).
The duration of the interruption should be short enough so that the safety valve travel does not move, but long
enough to so that a pressure drop across the solenoid valve is detected.
2. Properly configured, data collection will occur automatically and will be stored onboard the DVC6200 SIS.
3. With ValveLink software, upload the diagnostic data from the triggered profile menu.
4. Examine the graph and observe that there was a change in the pressure reading downstream of the solenoid.
If the solenoid valve is wired in series with the DVC6200 SIS and logic solver, the following steps can be used to test the
solenoid valve.
1. With ValveLink software, run the Solenoid Valve Test diagnostic. When configured correctly, the DVC6200 SIS will
conduct the power interruption and collect the data.
2. Examine the graph and observe that there was a change in the pressure reading downstream of the solenoid.

Section 6 Maintenance and Troubleshooting66
The DVC6200 SIS digital valve controller enclosure is rated Type 4X and IP66, therefore periodic cleaning of internal
components is not required. If the DVC6200 SIS
coated or layered with industrial or atmospheric contaminants, it is recommended that the vent (key 52) be
periodically removed and inspected to ensure there is no partial or full obstruction. If the vent appears to be partially or
fully obstructed, it must be cleaned or replaced. Lightly brush the exterior of the vent to remove contaminants and run
a mild water/detergent solution through the vent to ensure it is free of any obstruction. Allow the vent to dry before
reinstalling.
WARNING
Personal injury or property damage can occur from cover failure due to overpressure. Ensure that the housing vent
opening is open and free of debris to prevent pressure buildup under the cover.
WARNING
is installed in an area where the exterior surfaces tend to get heavily
To avoid static discharge from the plastic cover when flammable gases or dust are present, do not rub or clean the cover
with solvents. To do so could result in a spark that may cause the flammable gases or dust to explode, resulting in personal
injury or property damage. Clean with a mild detergent and water only.
WARNING
Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before performing
any maintenance procedures on the DVC6200 SIS digital valve controller:
D Always wear protective clothing, gloves, and eyewear.
D Do not remove the actuator from the valve while the valve is still pressurized.
D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the valve.
D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure
from both sides of the valve.
D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
D Vent the pneumatic actuator loading pressure and relieve any actuator spring precompression so the actuator is not
applying force to the valve stem; this will allow for the safe removal of the stem connector.
WARNING
When using natural gas as the supply medium, or for explosion proof applications, the following warnings also apply:
D Remove electrical power before removing the housing cap. Personal injury or property damage from fire or explosion
may result if power is not disconnected before removing the cap.
D Remove electrical power before disconnecting any of the pneumatic connections.
61
Maintenance and Troubleshooting
February 2021
D When disconnecting any of the pneumatic connections or any pressure retaining part, natural gas will seep from the
unit and any connected equipment into the surrounding atmosphere. Personal injury or property damage may result
from fire or explosion if natural gas is used as the supply medium and appropriate preventive measures are not taken.
Preventive measures may include, but are not limited to, one or more of the following: ensuring adequate ventilation
and the removal of any ignition sources.
D Ensure that the cover is correctly installed before putting this unit back into service. Failure to do so could result in
personal injury or property damage from fire or explosion.

The HART (Highway Addressable Remote Transducer) protocol gives field devices the capability of communicating
instrument and process data digitally. This digital communication occurs over the same two‐wire loop that provides
the 4‐20 mA process control signal, without disrupting the process signal. In this way, the analog process signal, with
its faster update rate, can be used for control. At the same time, the HART protocol allows access to digital diagnostic,
maintenance, and additional process data. The protocol provides total system integration via a host device.
The HART protocol uses frequency shift keying (FSK). Two individual frequencies of 1200 and 2200 Hz are
superimposed over the 4‐20 mA current signal. These frequencies represent the digits 1 and 0 (see figure A‐1). By
superimposing a frequency signal over the 4-20 mA current, digital communication is attained. The average value of
the HART signal is zero, therefore no DC value is added to the 4‐20 mA signal. Thus, true simultaneous communication
is achieved without interrupting the process signal.

The HART protocol allows the capability of multidropping, i.e., networking several devices to a single communications
line. This process is well suited for monitoring remote applications such as pipelines, custody transfer sites, and tank
farms. See table 6‐2 for instructions on changing the printed wiring board DIP switch configuration to multidrop.
DVC6200 SIS Digital Valve Controller
The DVC6200 SIS digital valve controller housing contains the travel sensor, terminal box, pneumatic input and output
connections and a module base that may be easily replaced in the field without disconnecting field wiring or tubing.
The module base contains the following submodules: I/P converter, printed wiring board (pwb) assembly, and
pneumatic relay. The relay position is detected by sensing the magnet on the relay beam via a detector on the printed
wiring board. This sensor is used for the minor loop feedback (MLFB) reading. The module base can be rebuilt by
replacing the submodules. See figures A‐3, A‐4, A‐5, and A‐6.

DVC6200 SIS digital valve controllers are loop‐powered instruments that provide a control valve position proportional
to an input signal from the control room. The following describes a double‐acting digital valve controller mounted on a
piston actuator.
The input signal is routed into the terminal box through a single twisted pair of wires and then to the printed wiring
board assembly submodule where it is read by the microprocessor, processed by a digital algorithm, and converted
into an analog I/P drive signal.
As the input signal increases, the drive signal to the I/P converter increases, increasing the I/P output pressure. The I/P
output pressure is routed to the pneumatic relay submodule. The relay is also connected to supply pressure and
amplifies the small pneumatic signal from the I/P converter. The relay accepts the amplified pneumatic signal and
provides two output pressures. With increasing input (4 to 20 mA signal), the output A pressure always increases and
the output B pressure decreases. The output A pressure is used for double‐acting and single‐acting direct applications.
The output B pressure is used for double‐acting and single‐acting reverse applications. As shown in figure A‐3, A‐4, and
A‐5, the increased output A pressure causes the actuator stem to move downward. Stem position is sensed by the
non‐contact travel feedback sensor. The stem continues to move downward until the correct stem position is
attained. At this point the printed wiring board assembly stabilizes the I/P drive signal. This positions the flapper to
prevent any further increase in nozzle pressure.
As the input signal decreases, the drive signal to the I/P converter submodule decreases, decreasing the I/P output
pressure. The pneumatic relay decreases the output A pressure and increases the output B pressure. The stem moves
upward until the correct position is attained. At this point the printed wiring board assembly stabilizes the I/P drive
signal. This positions the flapper to prevent any further decrease in nozzle pressure.

The following control modes are available for a
FIELDVUE Instrument:
Analog The instrument receives its travel set
point over the 4‐20 mA loop.
Digital The instrument receives its set point
digitally, via the HART communications link.
Test This is not a user‐selectable mode. The
Device Communicator or ValveLink software
places the instrument in this mode whenever it
needs to move the valve, such as for calibration or
diagnostic tests.
Bench Set
Pressure, supplied to an actuator, required to
drive the actuator through rated valve travel.
Expressed in pounds per square inch.
Breakout Timeout
The user configured amount of time before which
the valve must leave the normal end during a
Partial Stroke test.
Byte
A unit of binary digits (bits). A byte consists of
eight bits.
Calibration Location
Where the instrument was last calibrated; either
in the factory or in the field.
Configuration
Stored instructions and operating parameters for
a FIELDVUE Instrument.
Control Mode, Restart
Determines the instrument control mode after a
restart. See Control Mode for the available restart
control modes.
Controller
A device that operates automatically to regulate a
controlled variable.
Current‐to‐Pressure (I/P) Converter
An electronic component or device that converts
a milliamp signal to a proportional pneumatic
pressure output signal.
Cycle Counter
The capability of a FIELDVUE instrument to record
the number of times the travel changes direction.
The change in direction must occur after the
deadband has been exceeded before it can be
counted as a cycle.

Cycle Counter Alert
Checks the difference between the Cycle Counter
and the Cycle Counter Alert Point. Cycle Counter
Alert is active when the cycle counter value
exceeds the Cycle Counter Alert Point. It clears
after you reset the Cycle Counter to a value less
than the alert point.
Cycle Counter Alert Point
An adjustable value which, when exceeded,
activates the Cycle Counter Alert. Valid entries
are 0 to 4 billion cycles.
Cycle Counter Deadband
Region around the travel reference point, in
percent of ranged travel, established at the last
increment of the Cycle Counter. The deadband
must be exceeded before a change in travel can
be counted as a cycle. Valid entries are 0% to
100%. Typical value is between 2% and 5%.
Deviation
Usually, the difference between set point and
process variable. More generally, any departure
from a desired or expected value or pattern.
Drive Signal Alert
Checks the drive signal and calibrated travel. If
one of the following conditions exists for more
than 20 seconds, the Drive Signal Alert is active. If
none of the conditions exist, the alert is cleared.
If Zero Power Condition = Closed
The alert is active when:
drive signal <10% and calibrated travel >3%
drive signal >90% and calibrated travel <97%
If Zero Power Condition = Open
The alert is active when:
drive signal <10% and calibrated travel <97%
drive signal >90% and calibrated travel >3%
Equal Percentage
A valve flow characteristic where equal
increments of valve stem travel produce equal
percentage changes in existing flow. One of the
input characteristics available for a FIELDVUE
Instrument. See also, Linear and Quick Opening.
Feedback Signal
Indicates to the instrument the actual position of
the valve. The travel sensor provides the feedback
signal to the instrument printed wiring board
assembly.
Firmware Revision
The revision number of the instrument firmware.
Firmware is a program that is entered into the
instrument at time of manufacture and cannot be
changed by the user.
Device ID
Unique identifier embedded in the instrument at
the factory.
Device Revision
Revision number of the interface software that
permits communication between the Device
Communicator and the instrument.

The signal to the I/P converter from the printed
wiring board. It is the percentage of the total
microprocessor effort needed to drive the valve
fully open.
100
Free Time
Percent of time that the microprocessor is idle. A
typical value is 25%. The actual value depends on
the number of functions in the instrument that
are enabled and on the amount of
communication currently in progress.
Full Ranged Travel
Current, in mA, that corresponds with the point
where ranged travel is maximum, i.e., limited by
the mechanical travel stops.
Gain
The ratio of output change to input change.
