Description
DVC6200 digital valve controllers (figures 1‐1 and 1‐2) are communicating, microprocessor‐based
current‐to‐pneumatic instruments. In addition to the traditional function of converting an input current signal to a pneumatic output pressure, the DVC6200 digital valve controller, using the HART r communications protocol, gives easy access to information critical to process operation. You can gain information from the principal component of the process, the control valve itself, using the Device Communicator at the valve, or at a field junction box, or by using a personal computer or operator's console within the control room. Additionally, an option is available which provides isolated circuitry for a valve position transmitter (for separate valve position feedback) or an integrated switch that can be set as a limit switch or an alert switch.

Control System Requirements
There are several parameters that should be checked to ensure the control system is compatible with the DVC6200 digital valve controller.
HART Filter
Depending on the control system you are using, a HART filter may be needed to allow HART communication. The
HART filter is a passive device that is inserted in field wiring from the HART loop. The filter is normally installed near the
output from modulated HART communication signals and raise the impedance of the control system to allow HART communication. For more information on the description and use of the HART filter, refer to the appropriate HART filter instruction manual.
To determine if your system requires a filter contact your Emerson sales office .
Note
A HART filter is typically NOT required for any of the Emerson control systems, including PROVOX t , RS3 t , and DeltaV t systems.

Voltage Available
The voltage available at the DVC6200 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 2‐2, the voltage available at the instrument depends upon:
D the control system compliance voltage
D if a filter, wireless THUM adapter, or intrinsic safety barrier is used, and
D the wire type and length.
The control system compliance voltage is the maximum voltage at the control system output terminals at which the control system can produce maximum loop current.
The voltage available at the instrument may be calculated from the following equation:
Voltage Available = [Control System Compliance Voltage (at maximum current)] - [filter voltage drop (if a HART filter is used)] - [total cable resistance maximum current] - [barrier resistance x maximum current].
The calculated voltage available should be greater than or equal to 10 volts DC.
Table 2‐1 lists the resistance of some typical cables.
The following example shows how to calculate the voltage available for a Honeywell t TDC2000 control system with a
HF340 HART filter, and 1000 feet of Belden t 9501 cable:
Voltage available = [18.5 volts (at 21.05 mA)] - [2.3 volts] - [48 ohms 0.02105 amps]
Voltage available = [18.5] - [2.3] - [1.01]
Voltage available = 15.19 volts

– Smart Wireless THUM adapter voltage drop (if used) 2
– Total loop cable resistance x maximum loop current – 1.01 volts (48 ohms x 0.02105 amps for
1000 feet of Belden 9501 cable)
= Voltage available at the instrument 3 = 15.19 volts, available—if safety barrier (2.55 volts) is not used
NOTES:
1
Obtain filter voltage drop. The measured drop will be different than this value. The measured filter voltage drop depends upon control system output voltage, the intrinsic safety barrier (if used), and the instrument. See note 3.

The voltage drop of the THUM adapter is linear from 2.25 volts at 3.5 mA to 1.2 volts at 25 mA.
The voltage available at the instrument is not the voltage measured at the instrument terminals. Once the instrument is connected, the instrument limits the measured voltage to approximately 8.0 to 9.5 volts.

Auxiliary Terminal Wiring Length Guidelines
The Auxiliary Input Terminals of a DVC6200 with instrument level ODV can be used with a locally‐mounted switch for initiating a partial stroke test. Some applications require that the switch be installed remotely from the DVC6200.
The length for wiring connected to the Auxiliary Input Terminals is limited by capacitance. For proper operation of the
Auxiliary Input Terminals capacitance should not exceed 100,000 pF. As with all control signal wiring, good wiring practices should be observed to minimize adverse effect of electrical noise on the Aux Switch function.
Example Calculation: Capacitance per foot or per meter is required to calculate the length of wire that may be connected to the Aux switch input. The wire should not exceed the capacitance limit of 100,000 pF. Typically the wire manufacturer supplies a data sheet which provides all of the electrical properties of the wire. The pertinent parameter is the highest possible capacitance. If shielded wire is used, the appropriate number is the “Conductor to Other
Conductor & Shield” value.
Example — 18AWG Unshielded Audio, Control and Instrumentation Cable
Manufacturer's specifications include:
Nom. Capacitance Conductor to Conductor @ 1 KHz: 26 pF/ft
Nom. Conductor DC Resistance @ 20 Deg. C: 5.96 Ohms/1000 ft
Max. Operating Voltage - UL 200 V RMS (PLTC, CMG),150 V RMS (ITC)
Allowable Length with this cable = 100,000pF /(26pF/ft) = 3846 ft
Example — 18AWG Shielded Audio, Control and Instrumentation Cable
Manufacturer's specifications include:
Nom. Characteristic Impedance: 29 Ohms
Nom. Inductance: .15 μ H/ft
Nom. Capacitance Conductor to Conductor @ 1 KHz: 51 pF/ft
Nom. Cap. Cond. to other Cond. & Shield @ 1 KHz 97 pF/ft
Allowable Length with this cable = 100,000pF /(97pF/ft) = 1030 ft
The AUX switch input passes less than 1 mA through the switch contacts, and uses less than 5V, therefore, neither the resistance nor the voltage rating of the cable are critical. Ensure that switch contact corrosion is prevented. It is generally advisable that the switch have gold‐plated or sealed contacts.
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 master
(pF)] [C cable
(pF/ft)]
Length(m) = [160,000 - C master
(pF)] [C cable
(pF/m)] where:
160,000 = a constant derived for FIELDVUE instruments to ensure that the HART network RC time constant will be no greater than 65 μ s (per the HART specification).
C master
= the capacitance of the control system or HART filter
C cable
= the capacitance of the cable used (see table 2‐1)
12
Instruction Manual
D103605X012
Wiring Practices
November 2019
The following example shows how to calculate the cable length for a Foxboro t
I/A control system (1988) with a C master 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.

Commissioning the Digital Valve Controller for use with the HART
Tri‐Loop Signal Converter
To prepare the digital valve controller for use with a 333 HART Tri‐Loop, you must configure the digital valve controller to burst mode, and select Burst Command 3. In burst mode, the digital valve controller provides digital information to the HART Tri‐Loop HART‐to‐Analog Signal Converter. The HART Tri‐Loop converts the digital information to a 4 to 20 mA analog signal. Each burst message contains the latest value of the primary (analog input), secondary (travel target), tertiary (configured output pressure), and quaternary (travel) variables.
To commission a DVC6200 for use with a HART Tri‐Loop, perform the following procedures.

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.
d Advanced Settings allows additional custom configuration of calibration parameters. This is for advanced use when calibrating large actuators.

Mode and Protection
Device Communicator Configure > Manual Setup > Mode and Protection (2‐2‐1)
Instrument Mode
There are two instrument modes for the DVC6200; In Service or Out of Service. In Service is the normal operating mode such that the instrument follows the 420 mA 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: 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.

Cutoffs and Limits
D Hi Limit/Cutoff Select — When the Hi Cutoff/Limit Select is configured for Cutoff, the Travel Target is set to 123% when the Travel exceeds the Hi Cutoff Point. When the Hi Cutoff/Limit Select is configured for Limit, the Travel
Target will not exceed the Hi Limit Point.
D Hi Limit/Cutoff Point— This is the point within the calibrated travel range above which the Limit or Cutoff is in effect.
When using cutoffs, a Cutoff Hi of 99.5% is recommended to ensure valve goes fully open. The Hi Cutoff/Limit is deactivated by setting it to 125%.
D Hi Soft Cutoff Rate —This setting allows the valve to ramp to the high travel extreme when the Cutoff Point is reached at the configured rate. This provides a controlled ramp into the seat in order to minimize seat damage.
When set to 0%/sec, the Soft Cutoff rate is disabled.
D Lo Limit/Cutoff Select— When the Lo Cutoff/Limit Select is configured for Cutoff, the Travel Target is set to 23% when the Travel is below the Lo Cutoff Point. When the Hi Cutoff/Limit Select is configured for Limit, the Travel
Target will not fall below the Lo Limit Point.
D Lo Limit/Cutoff Point —This is the point within the calibrated travel range below which the Limit or Cutoff is in effect.
When using cutoffs, a Cutoff Lo of 0.5% is recommended to help ensure maximum shutoff seat loading. The Lo
Limit/Cutoff is deactivated by setting it to 25%.
D Lo Soft Cutoff Rate —This setting allows the valve to ramp to the low travel extreme when the Cutoff Point is reached at the configured rate. This provides a controlled ramp into the seat in order to minimize seat damage. When set to
0%/sec, the Soft Cutoff rate is disabled.
Pressure Control
D Pressure Range High —The high end of output pressure range. Enter the pressure that corresponds with 100% valve travel when Zero Power Condition is closed, or 0% valve travel when Zero Power Condition is open. This pressure must be greater than the Pressure Range Lo.
D Pressure Range Lo —The low end of the output pressure range. Enter the pressure that corresponds to 0% valve travel when Zero Power Condition is closed, or 100% valve travel when Zero Power Condition is open. This pressure must be less than the Pressure Range Hi.

Pressure Fallback
Note
Pressure Fallback is available for instrument level AD, PD, ODV.
D Tvl Dev Press Fallback — When the difference between the travel target and the actual travel exceeds this value for more than the Tvl Dev Press Fallback Time, the instrument will disregard the travel feedback and control based on output pressure.
D Tvl Dev Press Fallback Time — This is the time, in seconds, that the travel target and the actual travel must be exceeded before the instrument falls back into pressure control.
D Fallback Recovery — If the instrument has fallen into pressure control and the feedback problem is resolved, recovery to travel control can occur automatically or with manual intervention. To return to travel control when Manual
Recovery is selected, change the Fallback Recovery to Auto Recovery, and then back to Manual Recovery (if desired).
Control Mode
D Control Mode — This displays the current control mode of the instrument. This will show Analog if the instrument is in PointtoPoint mode and is using a 420 mA signal for its power and set point. This will show Digital if the instrument is in Multidrop mode and is using 24 VDC for power and a digital set point for control.
Note
Another mode, Test, may be displayed. Normally the instrument should not be in the Test mode. The digital valve controller automatically switches to this mode whenever it needs to stroke the valve during calibration or stroke valve, for example.
However, if you abort from a procedure where the instrument is in the test mode, it may remain in this mode. To take the instrument out of the Test mode, select Change Control Mode and enter Analog or Digital.
D Change Control Mode — This allows the user to configure the control mode to Analog or Digital.
D Restart Control Mode — This defines the Control Mode of the instrument after a restart (e.g. power cycle). Available choices are Resume Last, Analog and Digital.

Characterization
D Input Characterization
Input Characterization defines the relationship between the travel target and ranged set point. Ranged set point is the input to the characterization function. If the zero power condition equals closed, then a set point of 0% corresponds to a ranged input of 0%. If the zero power condition equals open, a set point of 0% corresponds to a ranged input of 100%.
Travel target is the output from the characterization function.
To select an input characterization, select Input Characterization from the Characterization menu. You can select from
relationship between the travel target and ranged set point for the fixed input characteristics, assuming the Zero
Power Condition is configured as closed.
You can specify 21 points on a custom characteristic curve. Each point defines a travel target, in % of ranged travel, for a corresponding set point, in % of ranged set point. Set point values range from -6.25% to 106.25%. Before modification, the custom characteristic is linear.
D Custom Characterization
To define a custom input character, select Custom Characterization from the Characterization menu .
Select the point you wish to define (1 to 21), then enter the desired set point value. Press Enter then enter the desired travel target for the corresponding set point. When finished, select point 0 to return to the Characterization menu.
With input characterization you can modify the overall characteristic of the valve and instrument combination.
Selecting an equal percentage, quick opening, or custom (other than the default of linear) input characteristic modifies the overall valve and instrument characteristic. However, if you select the linear input characteristic, the overall valve and instrument characteristic is the characteristic of the valve, which is determined by the valve trim (i.e., the plug or cage).

Dynamic Response
D SP Rate Open —Maximum rate (% of valve travel per second) at which the digital valve controller will move to the open position regardless of the rate of input current change. A value of 0 will deactivate this feature and allow the valve to stroke open as fast as possible.
D SP Rate Close —Maximum rate (% of valve travel per second) at which the digital valve controller will move to the close position regardless of the rate of input current change. A value of 0 will deactivate this feature and allow the valve to stroke close as fast as possible.
D Set Point Filter Time (Lag Time) —The Set Point Filter Time (Lag Time) slows the response of the digital valve controller. A value ranging from 0.2 to 10.0 can be used for noisy or fast processes to improve closed loop process control. Entering a value of 0.0 will deactivate the lag filter.
Note
Set Point Filter Time (Lag Time) is available for instrument level HC, AD, and PD.
D Lead/Lag Set Point Filter —ODV devices have access to a lead‐lag set point filter that can be used to improve a valve's dynamic response. The lead‐lag filter is part of the set point processing routine that reshapes the input signal before it becomes travel set point. Lead‐lag filters are characterized by lead and lag time constants.
Note
Lead/Lag is only available for instrument level ODV.
When the valve is in its active control region (off the seat), the lead‐lag filter improves small amplitude response by momentarily overdriving the travel set point. This is useful when the actuator is large and equipped with accessories.
As a result, any volume boosters that are present will be activated. The longer the lag time, the more pronounced the overdrive. Since the lead‐lag input filter is used to enhance the dynamic response of a control valve, filter parameters should be set after the tuning parameters have been established.
When the valve is at its seat, the lead‐lag filter also has a boost function that sets the initial conditions of the filter artificially low so that small amplitude signal changes appear to be large signal changes to the filter. The boost function introduces a large spike that momentarily overdrives the instrument and activates any external volume boosters that may be present. The lead‐lag boost function is normally disabled except for those cases where the valve must respond to small command signals off the seat. By setting the lead/lag ratio in the opening and closing directions to 1.0, the boost function can be enabled without introducing lead‐lag dynamics in the active control region. See table
3‐2 for typical lead‐lag filter settings.

D Stabilize/Optimize
WARNING
During Stabilize/Optimize the valve may move, causing process fluid or pressure to be released. To avoid personal injury and property damage caused by the release of process fluid or pressure, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the process fluid.
Stabilize/Optimize permits you to adjust valve response by changing the digital valve controller tuning. During this routine the instrument must be out of service, however, the instrument will respond to setpoint changes.
If the valve is unstable, select Decrease Response to stabilize valve operation. This selects the next lower tuning set
(e.g., F to E). If the valve response is sluggish, select Increase Response to make the valve more responsive. This selects the next higher tuning set (e.g., F to G).
If after selecting Decrease Response or Increase Response the valve travel overshoot is excessive, select Decrease

Travel Sensor Motion
WARNING
If you answer YES to the prompt for permission to move the valve when determining travel sensor motion, the instrument will move the valve through a significant portion of its travel range. To avoid personal injury and property damage caused by the release of process fluid or pressure, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the process fluid.
Select Clockwise/Toward Bottom, or Counterclockwise/Toward Top. Travel Sensor Motion establishes the proper travel sensor rotation. For quarter‐turn actuators determine rotation by viewing the rotation of the magnet assembly from the back of the instrument.
Note
Travel Sensor Motion in this instance refers to the motion of the magnet assembly. Note that the magnet assembly may be referred to as a magnetic array in user interface tools.
D For instruments with Relay A and C: If increasing air pressure at output A causes the magnet assembly to move down or the rotary shaft to turn clockwise, enter CW/To Bottom Inst. If it causes the magnet assembly to move up, or the rotary shaft to turn counterclockwise, enter CCW/To Top Inst.
D For instruments with Relay B: If decreasing air pressure at output B causes the magnet assembly to down, or the rotary shaft to turn clockwise, enter CW/To Bottom Inst. If it causes the magnet assembly to move up, or the rotary shaft to turn counterclockwise, enter CCW/To Top Inst.

Device Communicator Configure > Manual Setup > Partial Stroke (2-2-7)
Note
Partial Stroke is only available for instrument level ODV.
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 3‐4.

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
actuator in an attempt to move a stuck valve. During PST Calibration, the Partial Stroke Outgoing Pressure Threshold will be set automatically as follows: d Single 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.
d Double 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 value for actuators where the partial stroke start point is the same as the
Zero Power Condition.

D Fail Signal —Should the output circuit fail to operate properly, the output will attempt to drive to a known state.
Depending on the nature of the failure, the circuit may or may not be able to achieve this fail state. When 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.
Switch Configuration
Note
Switch Configuration is only available on units that have the optional 420 mA position transmitter or switch hardware installed.
D Limit Switch Trip Point— When the function is configured as a Limit Switch, this defines the threshold for the limit switch in percent of calibrated travel.
D Alert Switch Source— When the function is configured as a Alert Switch, this determines which alert will activate the switch. The alert choices are: Travel Deviation or Pressure Fallback.

D Switch Closed— This configures the action of the switch. The choices are: Below Trip Point / Alert Not Active or
Above Trip Point / Alert Active.
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.
Primary Variable (PV) Analog Input
Secondary Variable (SV) Travel, Travel Setpoint, Pressure A, Pressure B, Pressure AB, Supply Pressure,
Drive Signal, or Analog Input
Tertiary Variable (TV) Travel, Travel Setpoint, Pressure A, Pressure B, Pressure AB, Supply Pressure,
Drive Signal, or Analog Input
Quaternary Variable (QV) Travel, Travel Setpoint, Pressure A, Pressure B, Pressure AB, Supply Pressure,
Drive Signal, or Analog Input
Transmitter Output
Note
Transmitter Output is only available on units that have the optional 420 mA position transmitter or switch hardware installed.
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, select Command 3.

Instruction Manual
D103605X012
Note
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.
Note
If the instrument is configured to operate in pressure control mode, or detects an invalid travel sensor reading, the Travel variable will report pressure in percent of bench set range.
Alert Setup
Device Communicator Configure > Alert Setup (2‐3)
An alert is a notification that the instrument has detected a problem. Alerts that are enabled and active will be
Command 48 response structure which is can be read by any HART communicating host system (refer to the HART
Field Device Specification, D103639X012 ).
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.
Change to HART 5 / Change to HART 7
Device Communicator Service Tool > Maintenance > Change to HART 5 / Change to HART 7 (3-5-3) HC or (3-5-4) AD, PD or (3-5-5) ODV
Note
This procedure must never be done while the valve is in service and controlling the process. Depending on the control system or asset management system attached, complete system reset may be required to reestablish HART communication. Consult the system documentation for further information.
This procedure changes the instrument from HART Universal Revision 5 to HART Universal Revision 7 (or vice versa).
Before proceeding, verify that your systems are prepared to support HART Universal Revision 7 devices. Follow the prompts on the Device Communicator display.

Calibration Overview
When a DVC6200 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
Configure > Calibration > Travel Calibration > Auto Calibration . For more detailed calibration information, refer to the following calibration procedures.
Device Communicator Configure > Calibration (2-4)
Auto Travel Calibration - see page 40
Manual Travel Calibration - see page 41
Pushbutton Calibration - see page 42
Pressure Sensor Calibration - see page 43
Analog Input Calibration - see page 44
Relay Adjustment - see page 45
PST Calibration (ODV Instrument Level only) - see page 47
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 process fluid.

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
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.
Table 4‐1. Auto Calibrate Travel Error Messages
Error Message
Power failure occurred during Auto Calib
Auto Calib did not complete within the time limit.
Possible Problem and Remedy
The analog input signal to the instrument must be greater than 3.8 mA. Adjust the current output from the control system or the current source to provide at least 4.0 mA.
The problem may be one or the other of the following:
1. The tuning set selected is too low and the valve does not reach an end point in the allotted time.
Select Manual Setup > Tuning > Travel Tuning > Stabilize/Optimize then Increase Response (selects next higher tuning set).
2. The tuning set selected is too high, valve operation is unstable and does not stay at an end point for the allotted time. Select Manual Setup > Tuning > Travel Tuning > Stabilize/Optimize then Decrease
Response (selects next lower tuning set).
Prior to receiving this message, did the instrument output go from zero to full supply? If not, verify instrument supply pressure by referring to the specifications in the appropriate actuator instruction manual. If supply pressure is correct, check instrument pneumatic components (I/P converter and relay).
Insufficient travel
Drive signal exceed low limit; check supply pressure
Drive signal exceed high limit; check supply pressure
If the instrument output did go from zero to full supply prior to receiving this message, then verify proper mounting by referring to the appropriate mounting procedure in the Installation section and checking the magnet array for proper alignment.
1. Check supply pressure (reverse‐acting relay)
2. Friction is too high.
1. Check supply pressure (direct‐acting relay)
2. Friction is too high

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
Pressure range (used for Pressure Fallback) is not recalibrated during this procedure.
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.

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.
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
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
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 Limit/Cutoff Hi is active when the Travel exceeds the Hi Limit/Cutoff Point.
Travel Limit/Cutoff Lo is active when the Travel falls below the Lo Limit/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.
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.
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 Cycle Counter and Travel Accumulator Deadband applies to both the Cycle Count High Alert and the Travel
Accumulator High Alert. The deadband establishes a zone around a travel reference point. The travel reference point 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.

Partial Stroke Test
Note
Partial Stroke Test is only available for instrument level ODV.
The Partial Stroke Test allows DVC6200 digital valve controllers with instrument level ODV to perform a Valve
Signature type of test while the instrument is in service and operational. In some applications, it is important to be able to exercise and test the valve to verify that it will operate when commanded. This feature allows the user to partially stroke the valve while continually monitoring the input signal. If a demand arises, the test is aborted and the valve moves to its commanded position. The partial stroke valve travel is configurable between 1 and 30% maximum travel, in 0.1% increments. Data from the last partial stroke test is stored in the instrument memory for retrieval by ValveLink software.
The Partial Stroke Test allows you to perform a partial, 10%, stroke test (standard) or a custom stroke test. With the custom stroke test, the stroke may be extended up to 30%. Be sure to check plant guidelines before performing a custom stroke test. The purpose of this test is to ensure that the valve assembly moves upon demand.
A partial stroke test can be initiated when the valve is operating at either 4 or 20 mA (point‐to‐point mode).
When enabled, a partial stroke test may be initiated by the device (as a scheduled, auto partial stroke test), a remote pushbutton located in the field or at the valve, a Device Communicator, or ValveLink software.
For information on configuring the Partial Stroke Test, see Partial Stroke Variables in the Detailed Setup section.
D Automatic (Scheduled)
The Auto Partial Stroke Test allows the partial stroke test to be scheduled by the DVC6200. The test is scheduled in number of hours between tests. Any power cycle will reset the test clock timer.
D Local 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 5 seconds and then opened. To abort the test,

Solenoid Valve Health Monitoring
Solenoid valve health monitoring requires the following setup:
D Single-acting actuator
D Solenoid valve installed between the DVC6200 pressure output and the actuator
D Unused output pressure port of the DVC6200 connected between the solenoid and the actuator, close to the actuator
D Relay configured as “special application”
D Triggered profile enabled and the “Pressure Differential” trigger event selected.
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.
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.

Section 6 Maintenance and Troubleshooting
66
The DVC6200 digital valve controller enclosure is rated Type 4X and IP66, therefore periodic cleaning of internal components is not required. If the DVC6200 is installed in an area where the exterior surfaces tend to get heavily 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
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 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.

2b. Controller output Impedance too low.
2c. Cable capacitance too high.
2d. HART filter improperly adjusted.
2f. Controller output providing less than 4 mA to loop.
2g. Disconnected loop wiring cable at PWB.
2h. PWB DIP switch not set properly.
Action
1a. Check the control mode using the Device Communicator. If
in the Digital or Test mode, the instrument receives its set point as a digital signal. Control is not based on input current. Change
Control Mode to Analog.
1b. Check system compliance voltage (see Wiring Practices in
the Installation section.
1c. Check instrument status using the Device Communicator
(see Viewing Instrument Status in the Viewing Device
Information section).
1d. Calibrate the analog input sensor (see Analog Input
Calibration in the Calibration section).
1e. Excessive moisture in the terminal box can cause current
leakage. Typically the current will vary randomly if this is the case. Allow the inside of the terminal box to dry, then retest.
2a. Calculate Voltage Available (see Wiring Practices in the
Installation section). Voltage Available should be greater than or equal to 10 VDC.
2b. Install a HART filter after reviewing Control System
Compliance Voltage requirements (see Wiring Practices in the
Installation section).
2c. Review maximum cable capacitance limits (see Wiring
Practices in the Installation section).
2d. Check filter adjustment (see the appropriate HART filter
instruction manual).
2e. Check polarity of wiring and integrity of connections. Make
sure cable shield is grounded only at the control system.
2f. Check control system minimum output setting, which should
not be less than 3.8 mA.
2g. Verify connectors are plugged in correctly.
2h. Check for incorrect setting or broken DIP switch on the back
of the PWB. Reset switch or replace PWB, if switch is broken. See
table 6‐2 for switch setting information

2p. ValveLink hardlock defective or not programmed.
Action
2j. Use a 4-20 mA current source to apply power to the
instrument. Terminal voltage across the LOOP+ and LOOPterminals should be 8.0 to 9.5 VDC. If the terminal voltage is not
8.0 to 9.5 VDC, replace the PWB.
2k. Use the Device Communicator to set the polling address
(refer to the Detailed Setup section). From the Utility menu, select Configure Communicator > Polling > Always Poll . Set the instrument polling address to 0.
2l. Check continuity from each screw terminal to the
corresponding PWB connector pin. If necessary, replace the terminal box assembly.
2m. If necessary, repair or replace cable.
2p. Replace if defective or return to factory for programming.
If necessary, set protection to None.
If Out of Service, place In Service.
Check:
Travel Sensor Motion

Restart control mode (should be Analog)
4. ValveLink diagnostic tests provide erroneous results.
5. Device Communicator does not turn on.
3b. Restricted pneumatic passages in I/P converter.
3c. O‐ring(s) between I/P converter ass'y missing or hard
and flattened losing seal.
3d. I/P converter ass'y damaged/corroded/clogged.
3e. I/P converter ass'y out of spec.
3f. Defective module base seal.
3h. Defective 67CFR regulator, supply pressure gauge
jumps around.
4a. Defective pressure sensor.
4b. Pressure sensor O‐ring missing.
3b. Check screen in I/P converter supply port of the module base.
Replace if necessary. If passages in I/P converter restricted, replace I/P converter.
3d. Check for bent flapper, open coil (continuity),
contamination, staining, or dirty air supply. Coil resistance should be between 1680 ‐ 1860 ohms. Replace I/P assembly if damaged, corroded, clogged, or open coil.
3e. I/P converter ass'y nozzle may have been adjusted. Verify
drive signal (55 to 80% for double‐acting; 60 to 85% for single‐acting) with the valve off the stops. Replace I/P converter assembly if drive signal is continuously high or low.
3f. Check module base seal for condition and position. If
necessary, replace seal.
3g. Depress relay beam at adjustment location in shroud, look
for increase in output pressure. Remove relay, inspect relay seal.
Replace relay seal or relay if I/P converter assembly is good and air passages not blocked. Check relay adjustment.
Note: Battery pack can be charged while attached to the Device
Communicator or separately. The Device Communicator is fully operable while the battery pack is charging. Do not attempt to charge the battery pack in a hazardous area.

HART Communication
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
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
DVC6200 Digital Valve Controller
The DVC6200 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.

E1362
DVC6200 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.
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.
Control Mode, Restart
Determines the instrument control mode after a restart. See Control Mode for the available restart control modes.
Controller

Minimum Closing Time
Minimum time, in seconds, for the travel to decrease through the entire ranged travel. This rate is applied to any travel decrease. Valid entries are 0 to 400 seconds. Deactivate by entering a value of 0 seconds.
Minimum Opening Time
Minimum time, in seconds, for the travel to increase through the entire ranged travel. This rate is applied to any travel increase. Because of friction, actual valve travel may not respond in exactly the same time frame. Valid entries are 0 to 400 seconds. Deactivate by entering a value of
0 seconds.
Non‐Volatile Memory (NVM)
A type of semiconductor memory that retains its contents even though power is disconnected.
NVM contents can be changed during configuration unlike ROM which can be changed only at time of instrument manufacture. NVM stores configuration restart data.
Parallel
Simultaneous: said of data transmission on two or more channels at the same time.
Polling Address
Address of the instrument. If the digital valve controller is used in a point‐to‐point configuration, set the polling address to 0. If it is used in a multidrop configuration, or split range application, set the polling address to a value from 0 to 15.
98
Pressure Sensor
A FIELDVUE instrument internal device that senses pneumatic pressure. The DVC6200 has three pressure sensors: one to sense supply pressure and two to sense the output pressures.
Instruction Manual
D103605X012
Primary Master
Masters are communicating devices. A primary master is a communicating device permanently wired to a field instrument. Typically, a
HART‐compatible control system or a computer running ValveLink software is the primary master.
In contrast, a secondary master is not often permanently wired to a field instrument. The
Device Communicator or a computer running
ValveLink software communicating through a
HART modem could be considered a secondary master.
Note: If one type of master takes an instrument
Out Of Service, the same type must put it In
Service. For example, if a device set up as a primary master takes an instrument Out Of
Service, a device set up as a primary master must be used to place the instrument In Service.
Quick Opening
A valve flow characteristic where most of the change in flow rate takes place for small amounts of stem travel from the closed position. The flow characteristic curve is basically linear through the first 40 percent of stem travel. One of the input characteristics available for a FIELDVUE
Instrument. See also, Equal Percentage and
Linear.
Random Access Memory (RAM)
A type of semiconductor memory that is normally used by the microprocessor during normal operation that permits rapid retrieval and storage of programs and data. See also Read Only
Memory (ROM) and Non‐Volatile Memory (NVM).
Rate
Amount of change in output proportional to the rate of change in input.
Read‐Only Memory (ROM)
A memory in which information is stored at the time of instrument manufacture. You can examine but not change ROM contents.
Seat Load

Instruction Manual
D103605X012
Set Point Filter Time (Lag Time)
The time constant, in seconds, for the first‐order input filter. The default of 0 seconds will bypass the filter.
Software
Microprocessor or computer programs and routines that reside in alterable memory (usually
RAM), as opposed to firmware, which consists of programs and routines that are programmed into memory (usually ROM) when the instrument is manufactured. Software can be manipulated during normal operation, firmware cannot.
Stroking Time
The time, in seconds, required to move the valve from its fully open position to fully closed, or vice versa.
Temperature Sensor
A device within the FIELDVUE instrument that measures the instrument's internal temperature.
Travel
Movement of the valve stem or shaft which changes the amount the valve is open or closed.
Travel Accumulator
The capability of a FIELDVUE instrument to record total change in travel. The value of the Travel
Accumulator increments when the magnitude of the change exceeds the Travel Accumulator
Deadband. To reset the Travel Accumulator, set it to zero.
Travel Accumulator Alert
Checks the difference between the Travel
Accumulator value and the Travel Accumulator
Alert Point. The Travel Accumulator Alert is active when the Travel Accumulator value exceeds the
Travel Accumulator Alert Point. It clears after you reset the Travel Accumulator to a value less than the alert point.
Travel Accumulator Alert Point
An adjustable value which, when exceeded, activates the Travel Accumulator Alert. Valid entries are 0% to 4 billion %.
Glossary
November 2019
Travel Accumulator Deadband
Region around the travel reference point established at the last increment of the accumulator. This region must be exceeded before a change in travel can be accumulated.
Valid entries are 0% to 100%.
Travel Alert
Checks the ranged travel against the travel high and low alert points. The travel alert is active if either the high or low point is exceeded. Once a high or low point is exceeded, the ranged travel must clear that point by the Travel Alert
Deadband before the alert clears. Four travel alerts are available: Travel Alert Hi, Travel Alert Lo,
Travel Alert Hi Hi, and Travel Alert Lo Lo.
Travel Alert Deadband
Travel, in percent of ranged travel, required to clear a travel alert, once it is active. Valid entries are -25% to 125%.
Travel Alert High Point
Value of the travel, in percent of ranged travel, which, when exceeded, sets the Travel Alert Hi alert. Valid entries are -25% to 125%.
Travel Alert High High Point
Value of the travel, in percent of ranged travel, which, when exceeded, sets the Travel Alert Hi Hi alert. Valid entries are -25% to 125%.
Travel Alert Low Point
Value of the travel, in percent of ranged travel, which, when exceeded, sets the Travel Alert Lo alert. Valid entries are -25% to 125%.
Travel Alert Low Low Point
Value of the travel, in percent of ranged travel, which, when exceeded, sets the Travel Alert Lo Lo alert. Valid entries are -25% to 125%.
Travel Cutoff
Defines the cutoff point for the travel, in percent of ranged travel. There are two travel cutoffs: high and low. Once travel exceeds the cutoff, the drive signal is set to either maximum or minimum, depending on the Zero Control Signal and if the cutoff is high or low. Minimum opening time or minimum closing time are not in effect while the travel is beyond the cutoff. Use the travel cutoff to obtain the desired seat load or to be sure the valve is fully open.
99
Glossary
November 2019
Travel Deviation
The difference between the analog input signal
(in percent of ranged input), the “target” travel, and the actual “ranged” travel.
Travel Deviation Alert
Checks the difference between the target and the ranged travel. If the difference 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 is less than the Travel Deviation Alert Point.
Travel Deviation Alert Point
An adjustable value for the target travel and the ranged travel difference, expressed in percent,
When this value is exceeded by the travel deviation for more than the Travel Deviation
Time, the Travel Deviation Alert is active. Valid entries are 0% to 100%. Typically this is set to 5%.
Travel Deviation Time
The time, in seconds. that the travel deviation must exceed the Travel Deviation Alert Point before the alert is active. Valid entries are 1 to 60 seconds.
Travel Limit
A setup parameter that defines the maximum allowable travel (in percent of ranged travel) for the valve. During operation, the travel target will not exceed this limit. There are two travel limits: high and low. Typically the travel limit low will be used to keep the valve from going completely closed.
Travel Range
Travel, in percent of calibrated travel, that corresponds to the input range.
Instruction Manual
D103605X012
Travel Sensor
A device within the FIELDVUE instrument that senses valve stem or shaft movement. The travel sensor in the DVC6200 is the Hall Effect sensor that measures the position of the magnetic assembly.
Travel Sensor Motion

Tuning
The adjustment of control terms or parameter values to produce a desired control effect.
Tuning Set
Preset values that identify gain settings for a
FIELDVUE instrument. The tuning set and supply pressure together determine an instrument's response to input signal changes.
Watch Dog Timer
A timer that the microprocessor must rearm periodically. If the microprocessor is unable to rearm the timer, the instrument goes through reset.
Zero Power Condition
The position of the valve (open or closed) when the electrical power to the instrument is removed. Zero Power Condition (ZPC) is determined by relay and actuator action as follows:
Single Acting Direct (Relay C) Upon loss of electrical power instrument goes to zero air output at port A.
