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

Description
DVC6200 digital valve controllers (figures 1‐1 and 1‐2) are communicating, microprocessor‐based current‐to‐pneumatic instruments. In addition to the normal function of converting an input current signal to a pneumatic output pressure, the DVC6200 digital valve controller, using the HARTr 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 Field Communicator at the valve, or at a field junction box, or by using a personal computer or operator's console within the control room.
Using a personal computer and ValveLink software or AMS Suite: Intelligent Device Manager, or a Field Communicator, you can perform several operations with the DVC6200 digital valve controller. You can obtain general information concerning software revision level, messages, tag, descriptor, and date.

Section 2 Wiring Practices22
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 field wiring terminals of the control system I/O (see figure 2‐1). Its purpose is to effectively isolate the control system 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 Process Management sales office.
Note
A HART filter is typically NOT required for any of the Emerson Process Management control systems, including PROVOXt, RS3t, and DeltaVt 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.

Instruction Manual
D103605X012
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 Honeywellt TDC2000 control system with a HF340 HART filter, and 1000 feet of Beldent 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

NOTES:
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

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 μH/ft Nom. Capacitance Conductor to Conductor @ 1 KHz: 51 pF/ft Nom. Cap. Cond. to other Cond. & Shield @ 1 KHz 97 pF/ft Allowable Length with this cable = 100,000pF /(97pF/ft) = 1030 ft
The AUX switch input passes less than 1 mA through the switch contacts, and uses less than 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
Length(m) = [160,000 - C
where:

Installation in Conjunction with a Rosemount 333 HART Tri‐Loop HART‐to‐Analog Signal Converter
Use the DVC6200 digital valve controller in operation with a Rosemount 333 HART Tri‐Loop HART‐to‐Analog Signal Converter to acquire an independent 4‐20 mA analog output signal for the analog input, travel target, pressure, or travel. The HART Tri‐Loop accepts any three of these digital signals and converts them into three separate 4‐20 mA analog channels.
Refer to figure 2‐4 for basic installation information. Refer to the 333 HART Tri‐Loop HART‐to‐Analog Signal Converter

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.
Note
The DVC6200 must be in HART 5 compatibility mode to use burst communications.

Mode and Protection
Field 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 420 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.

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, up to 12 characters.
Units
D Pressure UnitsDefines 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.
Note
Auxiliary Terminal Action is only available for instrument level ODV.
Analog Input Range
DInput Range Hi—Permits setting the Input Range High value. Input Range High should correspond to Travel Range
High, if the Zero Power Condition is configured as closed. If the Zero Power Condition is configured as open, Input Range High corresponds to Travel Range Low. See figure 3‐1.

D Fallback-Sensor/Tvl Deviation—The instrument will fallback to pressure control if a travel sensor failure is detected,
or if the Tvl Dev Press Fallback setting is exceeded for more than the Tvl Dev Press Fallback Time.
Note
Travel / Pressure Select must be set to Travel for double‐acting actuators
Cutoffs and Limits
DHi Limit/Cutoff SelectWhen 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.
DHi 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%.
DLo 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.
DLo 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%.
End Point Pressure Control (EPPC)
Note
End Point Pressure Control is available for instrument level ODV.
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 a certain value. This value is configured through the Upper Operating Pressure feature. Because the digital valve controller is constantly in control and not allowed to reach a dormant or saturated state, it is constantly testing its own pneumatic system. If there is an output pressure deviation, for example, the instrument will issue an alert. To ensure there is an alert when an output pressure deviation occurs, setup the alert as described under Pressure Deviation Alert.

Configuration
January 2015
Instruction Manual
D103605X012
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. If the valve is fail‐open, the upper operating pressure for all actuator is set to 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.
Pressure Control
DPressure 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.
DPressure 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.
DTvl Dev Press FallbackWhen 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.
DTvl Dev Press Fallback TimeThis is the time, in seconds, that the travel target and the actual travel must be
exceeded before the instrument falls back into pressure control.
DFallback RecoveryIf 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
DControl ModeThis displays the current control mode of the instrument. This will show Analog if the instrument is
in PointtoPoint mode and is using a 420 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 ModeThis allows the user to configure the control mode to Analog or Digital.
D Restart Control ModeThis defines the Control Mode of the instrument after a restart (e.g. power cycle). Available
choices are Resume Last, Analog and Digital.
Characterization
DInput 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 3‐2 or you can select a custom characteristic. Figure 3‐2 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.
DCustom 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
DSP Rate Open—Maximum rate (% of valve travel per second) at which the digital valve controller will move to the
open position regardless of the rate of input current change. A value of 0 will deactivate this feature and allow the valve to stroke open as fast as possible. In firmware 2, 3, and 4 this parameter should be set to 0.
DSP Rate Close—Maximum rate (% of valve travel per second) at which the digital valve controller will move to the
close position regardless of the rate of input current change. A value of 0 will deactivate this feature and allow the valve to stroke close as fast as possible. In firmware 2, 3, and 4 this parameter should be set to 0.
DSet Point Filter Time (Lag Time)—The Set Point Filter Time (Lag Time) slows the response of the digital valve
controller. A value ranging from 0.2 to 10.0 can be used for noisy or fast processes to improve closed loop process control. Entering a value of 0.0 will deactivate the lag filter. In firmware 2, 3, and 4 this parameter should be set to 0.
Note
Set Point Filter Time (Lag Time) is available for instrument level HC, AD, and PD.
DLead/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.

Lag Time First order time constant. A value of 0.0 will disable the lead‐lag filter. 0.2 sec

In addition, you can specify Expert tuning and individually set the proportional gain, velocity gain, and minor loop feedback gain. Individually setting or changing any tuning parameter or running the Performance Tuner or Stabilize Optimize routint will automatically change the tuning set to X (expert).
Note
Use Expert tuning only if standard tuning has not achieved the desired results.
Stabilize/Optimize or Performance Tuner may be used to achieve the desired results more rapidly than manual Expert tuning.
Table 3‐4 provides tuning set selection guidelines for Fisher and Baumann actuators. These tuning sets are only recommended starting points. After you finish setting up and calibrating the instrument, you may have to select either a higher or lower tuning set to get the desired response. You can use the Performance Tuner to optimize tuning.

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.
DPerformance Tuner
WARNING
During performance tuning the valve may move, causing process fluid or pressure to be released. To avoid personal injury and property damage caused by the release of process fluid or pressure, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the process fluid.
Note
The Performance Tuner is available for instrument level AD, PD, and ODV, and can only be run while in Travel control mode.
The Performance Tuner is used to determine digital valve controller tuning. It can be used with digital valve controllers mounted on most sliding‐stem and rotary actuators, including Fisher and other manufacturers' products. Moreover, because the performance tuner can detect internal instabilities before they become apparent in the travel response, it can generally optimize tuning more effectively than manual tuning. Typically, the performance tuner takes 3 to 5 minutes to tune an instrument, although tuning instruments mounted on larger actuators may take longer.
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 Decrease Damping to select a damping value that allows more overshoot. Select Increase Damping to select a damping value that will decrease the overshoot. When finished, select done.

In addition, you can specify Expert tuning and individually set the pressure proportional gain, pressure integrator gain, and pressure minor loop feedback gain. Individually setting or changing any tuning parameter will automatically change the tuning set to X (expert).
Note
Use Expert tuning only if standard tuning has not achieved the desired results.
Stabilize/Optimize or Performance Tuner may be used to achieve the desired results more rapidly than Expert tuning.
DProportional Gain—the proportional gain for the pressure control tuning set. Changing this parameter will also
change the tuning set to Expert.

Note
As a general rule, do not use less than 60% of the magnet assembly travel range for full travel measurement. Performance will decrease as the assembly is increasingly subranged.
The linear magnet assemblies have a valid travel range indicated by arrows molded into the piece. This means that the hall sensor (on the back of the DVC6200 housing) has to remain within this range throughout the entire valve travel. The linear magnet assemblies are symmetrical. Either end may be up.

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

Partial Stroke Test (PST) (Instrument Level ODV only)
Field Communicator Configure > Manual Setup > Partial Stroke (2-2-6)
Note
Partial Stroke is only available for instrument level ODV.
Partial Stroke Test (PST)
DPST Pressure Limit This defines the actuator pressure at which a partial stroke test will abort. This prevents the
DVC6200 from exhausting (or building) excessive pressure to the actuator in an attempt to move a stuck valve. During Device Setup or Auto Travel Calibration, the Partial Stroke Pressure Limit will be set automatically as follows:
Single Acting Actuators - For those actuators that exhaust pressure from the partial test start point, the Pressure Limit will be a minimum value. For those actuators that build pressure from the partial test start point, the Pressure Limit will be a maximum value.
Double Acting Actuators - The Pressure Limit will be set to a negative value for actuators where the partial stroke start point is opposite of the Zero Power Condition (e.g., Partial Stroke Start Point = Open and Zero Power Condition = Closed) and to a positive valve for actuators where the partial stroke start point is the same as the Zero Power Condition.
The pressure signal used to determine this parameter depends on relay type and is summarized below.
Relay Type Pressure Signal
A or C Port A - Port B B Port B - Port A B Special App. Port B C Special App. Port A
To manually set the partial stroke pressure limit, you must examine current partial stroke test results using ValveLink software. The following steps will guide you through the process:
1. Connect the DVC6200 to a system running ValveLink software.
2. Disable the following parameters:

Note
Transmitter Output is only available on units that have the optional 420 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. Burst mode is only available in devices configured as HART Universal Revision 5.
D Burst Enable—This turns on or off the burst mode.
D Burst Command—This defines which HART command is configured for burst reporting. There are three options to
choose from. When using a TriLoop, select the third option.
- Analog Input (Command 1)
- Loop Current / Travel (Command 2)
- Loop Current / PV / SV / TV / QV (Command 3)
Note
Access to information in the instrument is normally obtained through the poll/response of HART communication. The Field Communicator or the control system may request any of the information that is normally available, even while the instrument is in burst mode. Between each burst mode transmission sent by the instrument, a short pause allows the Field Communicator or control system to initiate a request. The instrument receives the request, processes the response message, and then continues “bursting” the burst mode data.
Burst mode will be automatically disabled during diagnostics tests such as Valve Signature.
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.

An alert is a notification that the instrument has detected a problem. A shutdown is an action that the instrument takes to drive the air output to the Zero Power Condition as per figure 3‐3. Some alerts can be configured to shutdown the instrument. Refer to table 3‐9 for default alert and shutdown settings.
Alerts may be enabled or disabled with the instrument In Service, Out of Service, Protected, or Not Protected. However, the instrument must be Not Protected to enable or disable a shutdown. Alerts are not processed when a diagnostic is in progress.
If shutdown is enabled, and the alert is active, the instrument will latch in the shutdown state until power to the instrument is cycled and the alert has cleared. While in the shutdown condition, HART communication will continue if the instrument remains powered.
For a detailed explanation of the alerts and the recommended actions, refer to Section 5.

Section 4 Calibration 44
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.
Field Communicator Configure > Calibration (2-4)
Auto Travel Calibration - see page 38
Manual Travel Calibration - see page 39
Pushbutton Calibration - see page 40
Pressure Sensor Calibration - see page 41
Analog Input Calibration - see page 42
Relay Adjustment - see page 43
PST Calibration (ODV Instrument Level only) - see page 45
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 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.
Table 4‐1. Auto Calibrate Travel Error Messages
Error Message Possible Problem and Remedy
Power failure occurred during Auto Calib
Auto Calib did not complete within the time limit.
Insufficient travel
Drive signal exceed low limit; check supply pressure
Drive signal exceed high limit; check supply pressure
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).
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.

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 asfound data for future root cause analysis.

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). In applications where a spurious trip is to be minimized, 4 mA is the normal operating position.

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 Field Communicator, or ValveLink software.
DAutomatic (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.
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 5 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.
DField Communicator
1. Connect the Field Communicator to the LOOP terminals on the digital valve controller.
2. Turn on the Field Communicator.
3. From the Online menu, select Service Tools > Diagnostics > Partial Stroke Test.
4. Select either Standard (10%) or Custom. With the Custom Stroke Test, the stroke may be entered up to 30% with configurable stroking speed and pause time.
5. The currently configured Stroke, Stroking Speed, and Pause Time is displayed. Choose “Yes” to run the test using these values. Choose “No” to modify the values. The default value for Stroke Speed is 0.25%/second.
6. The valve begins to move and the actual travel reported by the digital valve controller is displayed on the Field Communicator.
7. Once the valve has reached the endpoint, check that the valve has reached the desired set point. The valve should return to its original position.

Maintenance and Troubleshooting
January 2015
Section 6 Maintenance and Troubleshooting66
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, however, it is recommended that the vent (key 52) be periodically inspected to ensure it is fully open. If the vent appears to be clogged, it can be removed, cleaned and 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 fully open. 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.
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
55

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.

Principle of Operation

Appendix A Principle of OperationAA−A
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 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.

ANALOG 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 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 and A‐4.

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. The output B pressure is used for double‐acting and single‐acting reverse applications. As shown in figure A‐3 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.

Stored instructions and operating parameters for a FIELDVUE Instrument.
Control Loop
An arrangement of physical and electronic components for process control. The electronic components of the loop continuously measure one or more aspects of the process, then alter those aspects as necessary to achieve a desired process condition. A simple control loop measures only one variable. More sophisticated control loops measure many variables and maintain specified relationships among those variables.
Control Mode
Defines where the instrument reads its set point. 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 Field Communicator or ValveLink software places the instrument in this mode whenever it needs to move the valve, such as for calibration or diagnostic tests.

D103605X012
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.

HART (acronym)
The acronym HART stands for Highway Addressable Remote Transducer.
HART Universal Revision
Revision number of the HART Universal Commands which are the communications protocol for the instrument.
Input Characteristic
The relationship between the ranged travel and ranged input. Possible values include: linear, equal percentage, and quick opening.
Input Current
The current signal from the control system that serves as the analog input to the instrument. See also Input Signal.
Input Range
The analog input signal range that corresponds to the travel range.
Input Signal
The current signal from the control system. The input signal can be displayed in milliamperes or in percent of ranged input.
Instrument Protection
Determines if commands from a HART device can calibrate and/or configure certain parameters in the instrument. There are two types of instrument protection: Configuration and Calibration: Prohibits changing protected setup parameters; prohibits calibration. None: Permits both configuration and calibration. The instrument is ”unprotected.”
Instrument Serial Number
The serial number assigned to the printed wiring board by the factory but can be changed during setup. The instrument serial number should match the serial number on the instrument nameplate.
Leak Class
Defines the allowable leakage by a valve when it is closed. Leak class numbers are listed in two standards: ANSI/FCI 70‐2 and IEC 534‐4.
Linear
A valve flow characteristic where changes in flow rate are directly proportional to changes in valve stem travel. One of the input characteristics available for a FIELDVUE Instrument. See also, Equal Percentage and Quick Opening.
Instrument Level
Determines the functions available for the instrument. See table 5‐1.
Instrument Mode
Determines if the instrument responds to its analog input signal. There are two instrument modes: In Service: For a fully functioning instrument, the instrument output changes in response to analog input changes. Typically changes to setup or calibration cannot be made when the instrument mode is In Service. Out of Service: The instrument output does not change in response to analog input changes when the instrument mode is Out of Service. Some setup parameters can be changed only when the instrument mode is Out of Service.
Linearity, dynamic
Linearity (independent) is the maximum deviation from a straight line best fit to the opening and closing curves and a line representing the average value of those curves.
Memory
A type of semiconductor used for storing programs or data. FIELDVUE instruments use three types of memory: Random Access Memory (RAM), Read Only Memory (ROM), and Non‐Volatile Memory (NVM). See also these listings in this glossary.
Menu
A list of programs, commands, or other activities that you select by using the arrow keys to highlight the item then pressing ENTER, or by entering the numeric value of the menu item.

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.
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 Field 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.
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.
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.
94
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
Force exerted on the valve seat, typically expressed in pounds force per lineal inch of port circumference. Seat load is determined by shutoff requirements.

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 %.
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.

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 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
Increasing or decreasing air pressure causes the magnet assembly to move up or down or the rotary shaft to turn clockwise or counterclockwise. The Setup Wizard asks if it can move the valve to determine travel.
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.
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.
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.
Double Acting (Relay A) Upon loss of electrical power instrument goes to full supply air output at port B. A goes to zero air output.
Single Acting Reverse (Relay B) Upon loss of electrical power instrument goes to full supply air output at Port B.
