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 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 Device Communicator at the valve, or at a field junction box, or by using a

Wiring Practices

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 sales office

Note

A HART filter is typically NOT required for any of the Emerson 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.

Wiring Practices

April 2022

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

CONTROL SYSTEM

Calculate Voltage Available at the Instrument as follows:

Control system compliance voltage

– Filter voltage drop (if used)

– Intrinsic safety barrier resistance (if used) x maximum loop current – 2.55 volts (121 ohms x 0.02105 amps)

– Smart Wireless THUM adapter voltage drop (if used)

– Total loop cable resistance x maximum loop current – 1.01 volts (48 ohms x 0.02105 amps for

= Voltage available at the instrument

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

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 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:

160,000 = a constant derived for FIELDVUE instruments to ensure that the HART network RC time constant will be no greater than 65 μs (per the HART specification).

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

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 Product Manual (00809-0100-4754

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

Fast-key sequences are only applicable to the 475 Field Communicator. They do not apply to the Trex Device Communicator.

Guided Setup

Device Communicator Configure > Guided Setup (2‐1)

To quickly setup the instrument, the following procedures will guide you through the process.

Device Setup is used to configure the unique parameters for the valve, actuator, instrument and accessory construction. After Device Setup is complete, proceed with Auto Calibration.

Auto Calibration is used to establish the limits of physical travel. During this process, the valve will fully stroke from one travel extreme to the other. There are three calibration options to choose from:

d Autocalibrate – Standard runs the full calibration process (recommended).

d Autocalibrate – Without Biases establishes the travel end points, but does not adjust the Minor Loop Feedback

bias. This is for advanced use when manually setting the biases for large actuators.

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

when calibrating large actuators.

Manual Setup33

Manual Setup allows you to configure the digital valve controller to your application. Table 3‐1 lists the default settings for a standard factory configuration. You can adjust actuator response, set the various modes, alerts, ranges, travel cutoffs and limits. You can also restart the instrument and set the protection.

Mode and Protection

Device 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.

Instrument

Device Communicator Configure > Manual Setup > Instrument (2‐2‐2)

Follow the prompts on the Device Communicator display to configure the following Instrument parameters:

Identification

D HART Tag—A tag name up to 8 characters is available for the instrument. The HART tag is the easiest way to

distinguish between instruments in a multi‐instrument environment. Use the HART tag to label instruments electronically according to the requirements of your application. The tag you assign is automatically displayed when the Device Communicator establishes contact with the digital valve controller at power‐up.

D HART Long Tag (HART Universal Revision 7 only)—A tag name up to 32 characters is available for the instrument.

Instruction Manual

D103605X012

D Description—Enter a description for the application with up to 16 characters. The description provides a longer

user‐defined electronic label to assist with more specific instrument identification than is available with the HART tag.

D Message—Enter any message with up to 32 characters. Message provides the most specific user‐defined means for

identifying individual instruments in multi‐instrument environments.

D Polling Address—If the digital valve controller is used in point‐to‐point operation, the Polling Address is 0. When

several devices are connected in the same loop, such as for split ranging, each device must be assigned a unique polling address. The Polling Address is set to a value between 0 and 63 for HART 7 and 0 and 15 for HART 5. To change the polling address the instrument must be Out Of Service.

For the Device Communicator to be able to communicate with a device whose polling address is not 0, it must be configured to automatically search for all or specific connected devices.

Configuration

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 Units—Defines the output and supply pressure units in either psi, bar, kPa, or kg/cm2.

D Temperature Units—Degrees Fahrenheit or Celsius. The temperature measured is from a sensor mounted on the

digital valve controller's printed wiring board.

D Analog Input Units—Permits defining the Analog Input Units in mA or percent of 4-20 mA range.

Terminal Box

D Calibration (CAL) Button—This button is near the wiring terminals in the terminal box and provides a quick means to

autocalibrate the instrument. The button must be pressed for 3 to 10 seconds. Autocalibration will move the valve through the full range of travel whether the Instrument Mode is In Service or Out of Service. However, if the Write Protection is Protected, this button will not be active. To abort, press the button again for 1 second. The calibration button is disabled by default.

D Auxiliary Terminal Action—These wire terminals can be configured to initiate a partial stroke test upon detection of

a short across the (+) and (-) terminals. The terminals must be shorted for 3 to 10 seconds.

Note

Auxiliary Terminal Action is only available for instrument level ODV.

Analog Input Range

D Input 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

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 open travel stop. When set to 0%/sec, the Hi 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 Lo 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.

Configuration

April 2022

Instruction Manual

D103605X012

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 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 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 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.

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 Proportional Gain—the proportional gain for the travel control tuning set. Changing this parameter will also change

the tuning set to Expert.

D Velocity Gain—the velocity gain for the travel control tuning set. Changing this parameter will also change the

tuning set to Expert.

D MLFB Gain—the minor loop feedback gain for the travel control tuning set. Changing this parameter will also change

the tuning set to Expert.

D Integral Enable—Yes or No. Enable the integral setting to improve static performance by correcting for error that

exists between the travel target and actual travel. Travel Integral Control is enabled by default.

D Integral Gain—Travel Integral Gain is the ratio of the change in output to the change in input, based on the control

action in which the output is proportional to the time integral of the input.

D 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 for a more conservative setting. If the valve response is sluggish, select increase response for a more aggressive setting. When finished select Done.

Pressure Tuning

D Pressure Tuning Set

There are twelve Pressure Tuning Sets to choose from. Each tuning set provides a preselected value for the digital valve controller gain settings. Tuning set C provides the slowest response and M provides the fastest response.

Tuning set B is appropriate for controlling a pneumatic positioner. Table 3‐5 lists the proportional gain, pressure integrator gain and minor loop feedback gain values for preselected tuning sets.

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 in ValveLink software, may be used to achieve the desired results more rapidly than Expert tuning.

D Proportional Gain—the proportional gain for the pressure control tuning set. Changing this parameter will also

change the tuning set to Expert.

D MLFB Gain—the minor loop feedback gain for the pressure control tuning set. Changing this parameter will also

change the tuning set to Expert.

D Integral Enable—Yes or No. Enable the pressure integral setting to improve static performance by correcting for

error that exists between the pressure target and actual pressure. Pressure Integral Control is enabled by default.

D Integral Gain—Pressure Integral Gain (also called reset) is the gain factor applied to the time integral of the error

signal between desired and actual pressure.This feature is used during pressure control for greater accuracy during pressure control/fallback. Changing this parameter will also change the tuning set to Expert.

Travel/Pressure Integral Settings

D Integral Dead Zone—A window around the Primary Setpoint in which integral action is disabled. The Dead Zone is

configurable from 0% to 2%, corresponding to a symmetric window from 0% to +/-2% around the Primary Setpoint.

Configuration

April 2022

Instruction Manual

D103605X012

Integral Dead Zone is used to eliminate friction induced limit cycles around the Primary Setpoint when the integrator is active. This dead zone value is used during the Auto Calibration of Travel procedure even if the travel integral is disabled; in the case of Auto Calibration travel failures with piston actuators, this value should be set to 1%. Default value is 0.26%.

D Integrator Limit—The Integrator Limit provides an upper limit to the integrator output. The high limit is configurable

from 0 to 100% of the I/P drive signal.

Valve and Actuator

Valve Style—Enter the valve style, rotary or sliding‐stem

Actuator Style—Enter the actuator style, spring and diaphragm, piston double‐acting without spring, piston

single‐acting with spring, or piston double‐acting with spring.

Feedback Connection—Refer to table 3‐6 for Feedback Connection options. Choose the assembly that matches the actuator travel range.

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.

D For instruments with Relay A and C: If increasing air pressure at output A causes the magnet assembly to move

down or the rotary shaft to turn clockwise, enter CW/To Bottom Inst. If it causes the magnet assembly to move up, or the rotary shaft to turn counterclockwise, enter CCW/To Top Inst.

D For instruments with Relay B: If decreasing air pressure at output B causes the magnet assembly to down, or the

rotary shaft to turn clockwise, enter CW/To Bottom Inst. If it causes the magnet assembly to move up, or the rotary shaft to turn counterclockwise, enter CCW/To Top Inst.

Maximum Supply Pressure

Enter the maximum supply pressure that is required to fully stroke the valve.

Configuration

Instruction Manual

D103605X012

Port A Pressure Limit

In single acting direct only applications, the instrument will limit the output pressure to the actuator from Port A. When this pressure limit is exceeded the device will go to the no air state.

CAUTION

This is a firmware controlled feature that requires loop power to the instrument. If loop power is lost, or there is an electronic or firmware failure, the protection feature will not remain in effect.

Output Pressure Limit Enable enables/disables the Port A Pressure Limit feature.

Note

There is an associated alert available with this feature. See the Port A Overpressurized alert in the Alert Setup section.

Partial Stroke Test (PST)

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.

Action On a Failed Test defines if the valve should step or ramp back on a failed stroke test.

Auto Test Interval is the interval of time in days between valve stroke tests that are automatically executed by the

digital valve controller, subject to the device being powered up. A value of 0 disables this feature.

Partial Stroke Parameters

Minimum Travel Movement is the percentage of total span that the valve moves away from its normal operating end

of travel towards its tripped end of travel during the test. The default value is 10%.

Short Duration PST, when enabled the incoming stroke is initiated as soon as the travel reaches the minimum travel movement. Refer to figure 3‐5 for a time series representation of this parameter.

Outgoing Ramp Rate is the rate at which the valve will move during the Outgoing stroke of the Partial Stroke test. The default value is 0.25%/second.

Incoming Ramp Rate is the rate at which the valve will move during the Incoming stroke of the Partial Stroke test. The default value is 0.25%/second.

Return Lead defines the percent (%) change in setpoint to overcome the hysteresis in the valve assembly. The error between setpoint and actual error is added to this percent change. For example, if the Return Lead is set at 0.5% and there is a 1% error this will be set at 1.5%

Breakout Timeout is the user configured amount of time before which the valve must leave the normal end during a PST.

Outgoing Pressure Threshold defines the actuator pressure at which a partial stroke test will abort during the outgoing stroke (see figure 3‐4). This prevents the DVC6200 from exhausting (or building) excessive pressure from/to the actuator in an attempt to move a stuck valve. During PST Calibration, the Partial Stroke Outgoing Pressure Threshold will be set automatically as follows:

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.

To manually set the partial stroke Outgoing Pressure Threshold, you must examine current partial stroke test results using ValveLink software. The following steps will guide you through the process:

1. Connect the DVC6200 to a system running ValveLink software.

2. Disable Partial Stroke Outgoing Pressure Limit by ensuring it is not selected as an evaluation criteria for PST Abnormal.

3. Run a partial stroke test.

4. Select the Press/Time radio button on the partial stroke graph (refer to the example in figure 3‐6). If the actuator pressure starts high and moves low, find the minimum actuator pressure (Pmin). If the actuator pressure starts low and moves high, find the maximum actuator pressure (Pmax). Doubleacting actuators will display differential pressure. Use table 3‐7 to estimate the Outgoing Pressure Threshold.

5. Enable the previously disabled Outgoing Pressure Limit - calculate the value using table 3‐7.

These menu items are only available on units that have the optional 420 mA position transmitter or switch hardware installed. For information on position transmitter/discrete switch wiring and configuration refer to the DVC6200 Series quick start guide,

D103556X012

D Output Terminal Enable—If using the optional output terminal for a Position Transmitter or Switch output, this must

be enabled with a user interface tool such as ValveLink software.

D Function—The output terminals can be configured as one of the following:

Transmitter - 420 mA output that represents 0100% of the calibrated valve travel.

Limit Switch - Discrete switch (1A max) that trips at a configurable point within 0100% of calibrated valve travel.

Alert Switch - Discrete switch (1A max) that trips based on a configurable device alert.

D Fail Signal—Should the output circuit fail to operate properly, the output will attempt to drive to a known state.

Depending on the nature of the failure, the circuit may or may not be able to achieve this fail state. When 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 420 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.

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 AB, Supply Pressure,

Drive Signal, or Analog Input

Tertiary Variable (TV) Travel, Travel Setpoint, Pressure A, Pressure B, Pressure AB, Supply Pressure,

Drive Signal, or Analog Input

Quaternary Variable (QV) Travel, Travel Setpoint, Pressure A, Pressure B, Pressure AB, Supply Pressure,

Drive Signal, or Analog Input

Transmitter Output

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.

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 TriLoop,

select Command 3.

- Read Additional Status (Command 48)

Configuration

April 2022

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.

D103605X012

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 recorded in the instrument memory within the Alert Record (see Section 5). Some alerts are also defined in the HART Command 48 response structure which is can be read by any HART communicating host system (refer to the 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 Adjustment on page 45.

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.

1. Check supply pressure (reverse‐acting relay)

2. Friction is too high.

1. Check supply pressure (direct‐acting relay)

2. Friction is too high

Manual Calibration

Two procedures are available to manually calibrate travel:

D Analog Adjust— This procedure is used when you can manually change the 4-20 mA current source to move the

valve.

D Digital Adjust— This procedure is used when the 4-20 mA current source cannot be manually changed.

Analog Calibration Adjust

Connect a variable current source to the instrument LOOP + and LOOP - terminals. The current source should be capable of generating 4 to 20 mA.

Follow the prompts on the Device Communicator display to calibrate the instrument's travel in percent.

Note

0% Travel = Valve Closed 100% Travel = Valve Open

1. Adjust the input current until the valve is near mid‐travel. Press OK.

Note

In steps 2 through 7 the accuracy of the current source adjustment affects the position accuracy.

2. Adjust the current source until the valve is at 0% travel, then press OK.

3. Adjust the current source until the valve is at 100% travel, then press OK.

4. Adjust the current source until the valve is at 0% travel, then press OK.

5. Adjust the current source until the valve is at 100% travel, then press OK.

6. Adjust the current source until the valve is at 5% travel, then press OK.

7. Adjust the current source until the valve is at 95% travel, then press OK.

8. Place the instrument In Service and verify that the travel properly tracks the current source.

Digital Calibration Adjust

Connect a variable current source to the instrument LOOP + and LOOP - terminals. The current source should be set between 4 and 20 mA.

Follow the prompts on the Device Communicator display to calibrate the instrument's travel in percent.

1. Adjust the input current until the valve is near mid‐travel. Press OK.

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.

Relay Adjustment

Before beginning travel calibration, check the relay adjustment. Replace the digital valve controller cover when finished.

Note

Relay B and C are not user‐adjustable.

Double‐Acting Relay

The double‐acting relay is designated by “Relay A” on a label affixed to the relay itself. For double‐acting actuators, the valve must be near mid‐travel to properly adjust the relay. The Device Communicator will automatically position the valve when Relay Adjust is selected.

Rotate the adjustment disc, shown in figure 4‐1, until the output pressure displayed on the Device Communicator is between 50 and 70% of supply pressure. This adjustment is very sensitive. Be sure to allow the pressure reading to stabilize before making another adjustment (stabilization may take up to 30 seconds or more for large actuators).

If the low bleed relay option has been ordered stabilization may take approximately two minutes longer than the standard relay.

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 when the Travel falls below the Travel Alert Hi Point minus the Travel Alert Deadband. See figure 5‐1.

Note

The Travel Alert Hi Hi and Travel Alert Lo Lo points are used to calculate the stroke time in the event of a demand. The values are typically set to 99% and 1% respectively, however it is not necessary to enable the alert. Stroke time can be read from the device with ValveLink software.

Travel Alert Hi-Hi is active when the Travel exceeds the Travel Alert Hi Hi Point. Once the alert is active, the alert will clear when the Travel falls below the Travel Alert Hi Hi Point minus the Travel Alert Deadband. See figure 5‐1.

Travel Alert Lo is active when the Travel is below the Travel Alert Lo Point. Once the alert is active, the alert will clear when the Travel exceeds the Travel Alert Lo Point plus the Travel Alert Deadband. See figure 5‐1.

Travel Alert Lo-Lo is active when the Travel is below the Travel Alert Lo Point. Once the alert is active, the alert will clear when the Travel exceeds the Travel Alert Lo Point plus the Travel Alert Deadband. See figure 5‐1.

Travel 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. See figure 5‐1.

Travel Sensor Failure is active if the sensed travel is outside the range of 25.0 to 125.0% of calibrated travel. If this alert is active, check the instrument mounting. Also, check that the electrical connection from the travel sensor is properly plugged into the printed wiring board assembly. After restarting the instrument, if the alert persists, troubleshoot the printed wiring board assembly or travel sensor.

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.

Instruction Manual

D103605X012

Device Information, Alerts, and Diagnostics

The Travel Alert Deadband applies to the Travel Deviation Alert as well as the Travel Alert Hi, Lo, Hi Hi, and Lo Lo. Figure 5‐1 illustrates the principle behind setting and clearing a Travel Alert Hi. The alert is set when the travel exceeds the alert point, and is cleared when it falls below the deadband.

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,

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 Device

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.

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.

Maintenance and Troubleshooting

April 2022

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, 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

Principle of Operation

April 2022

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.

+0.5V

A6174

-0.5V

1200 Hz “1”

AVERAGE CURRENT CHANGE DURING COMMUNICATION = 0

2200 Hz “0”

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, A‐4, A‐5, and A‐6.

D103605X012

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. The output B pressure is used for double‐acting and single‐acting reverse applications. As shown in figure A‐3, A‐4, and A‐5 the increased output A pressure causes the actuator stem to move downward. Stem position is sensed by the non‐contact travel feedback sensor. The stem continues to move downward until the correct stem position is attained. At this point the printed wiring board assembly stabilizes the I/P drive signal. This positions the flapper to prevent any further increase in nozzle pressure.

As the input signal decreases, the drive signal to the I/P converter submodule decreases, decreasing the I/P output pressure. The pneumatic relay decreases the output A pressure and increases the output B pressure. The stem moves upward until the correct position is attained. At this point the printed wiring board assembly stabilizes the I/P drive signal. This positions the flapper to prevent any further decrease in nozzle pressure.

Instruction Manual

D103605X012

Glossary

April 2022

Alert Point

An adjustable value that, when exceeded, activates an alert.

Algorithm

A set of logical steps to solve a problem or accomplish a task. A computer program contains one or more algorithms.

Alphanumeric

Consisting of letters and numbers.

Analog Input Units

Units in which the analog input is displayed and maintained in the instrument.

ANSI (acronym)

The acronym ANSI stands for the American National Standards Institute

ANSI Class

Valve pressure/temperature rating.

Bench Set

Pressure, supplied to an actuator, required to drive the actuator through rated valve travel. Expressed in pounds per square inch.

Byte

A unit of binary digits (bits). A byte consists of eight bits.

Calibration Location

Where the instrument was last calibrated; either in the factory or in the field.

Configuration

Stored instructions and operating parameters for a FIELDVUE Instrument.

Control 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 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

A device that operates automatically to regulate a controlled variable.

Current‐to‐Pressure (I/P) Converter

An electronic component or device that converts a milliamp signal to a proportional pneumatic pressure output signal.

Cycle Counter

The capability of a FIELDVUE instrument to record the number of times the travel changes direction. The change in direction must occur after the deadband has been exceeded before it can be counted as a cycle.

Glossary

April 2022

Instruction Manual

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.

Feedback Signal

Indicates to the instrument the actual position of the valve. The travel sensor provides the feedback signal to the instrument printed wiring board assembly.

Firmware Revision

The revision number of the instrument firmware. Firmware is a program that is entered into the instrument at time of manufacture and cannot be changed by the user.

Device ID

Unique identifier embedded in the instrument at the factory.

Device Revision

Revision number of the interface software that permits communication between the Device Communicator and the instrument.

Drive Signal

The signal to the I/P converter from the printed wiring board. It is the percentage of the total microprocessor effort needed to drive the valve fully open.

Free Time

Percent of time that the microprocessor is idle. A typical value is 25%. The actual value depends on the number of functions in the instrument that are enabled and on the amount of communication currently in progress.

Full Ranged Travel

Current, in mA, that corresponds with the point where ranged travel is maximum, i.e., limited by the mechanical travel stops.

Gain

The ratio of output change to input change.

Hardware Revision

Revision number of the Fisher instrument hardware. The physical components of the instrument are defined as the hardware.

Instruction Manual

D103605X012

Glossary

April 2022

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.

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 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.

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 for HART 5 and 0 to 63 for HART 7.

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.

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.
