The FIELDVUE DVC6200 SIS 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 SIS 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.

Logic Solver or Control System Requirements

There are several parameters that should be checked to ensure the logic solver or control system is compatible with the DVC6200 SIS digital valve controller.

HART Filter / Line Conditioner

Depending on the logic solver or control system and operational mode of the DVC6200 SIS digital valve controller, a line conditioner or HART filter may be required.

Required?

No No

Line Conditioner

Required?

The HF340 HART filter and LC340 Line Conditioner are passive devices that are inserted in the field wiring of the HART loop. A filter or line conditioner is normally installed near the field wiring terminals of the system I/O (see figure 2‐1). Its purpose is to effectively isolate the system output from modulated HART communication signals and raise the impedance of the system to allow HART communication. For more information, refer to the HF340 HART filter

(D102796X012) or LC340 Line Conditioner (D102797X012) instruction manual.

Voltage Available

The voltage available at the DVC6200 SIS digital valve controller must be at least 10 VDC. The voltage available at the instrument is not the actual voltage measured at the instrument when the instrument is connected. The voltage measured at the instrument is limited by the instrument and is typically less than the voltage available.

As shown in figure 2‐1, the voltage available at the instrument depends upon:

D The logic solver or control system compliance voltage

D if a line conditioner filter or intrinsic safety barrier is used, and

D the wire type and length.

The compliance voltage is the maximum voltage at the logic solver or control system output terminals at which the system can produce maximum loop current.

The voltage available at the instrument may be calculated from the following equation:

Voltage Available = [Compliance Voltage (at maximum current)] - [line conditioner/filter voltage drop] - [total cable resistance  maximum current] - [barrier resistance x maximum current].

The calculated voltage available should be greater than or equal to 10 volts DC.

VOLTAGE AVAILABLE AT THE

INSTRUMENT

Calculate Voltage Available at the Instrument as follows:

Logic solver or control system compliance voltage

– Line conditioner or filter voltage drop (if used)

Example Calculation

18.5 volts (at 21.05 mA for Honeywell TDC2000)

– 2 volts

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

– Total loop cable resistance x maximum loop current

= Voltage available at the instrument

– 1.01 volts (48 ohms x 0.02105 amps for 1000 feet of Belden 9501 cable)

= 15.49 volts, available—if safety barrier (2.55 volts) is not used

NOTES:

Obtain filter voltage drop. The measured drop will be different than this value. The measured filter voltage drop

depends upon control system output voltage, the intrinsic safety barrier (if used), and the instrument. See note 2.

The voltage available at the instrument is not the voltage measured at the instrument terminals. Once the instrument is

connected, the instrument limits the measured voltage to approximately 8.0 to 9.5 volts.

Compliance Voltage

If the compliance voltage of the logic solver or control system is not known, perform the following compliance voltage test.

1. Disconnect the field wiring from the system and connect equipment as shown in figure 2‐2 to the system terminals.

2. Set the system to provide maximum output current.

3. Increase the resistance of the 1 kW potentiometer, shown in figure 2‐2, until the current observed on the milliammeter begins to drop quickly.

4. Record the voltage shown on the voltmeter. This is the compliance voltage.

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

(pF/m)]

where:

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

The following example shows how to calculate the cable length for a Foxboro

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 Process Management sales office for specific information relating to your control system.

Auxiliary Terminal Wiring Length Guidelines

The Auxiliary Input Terminals of a DVC6200 SIS can be used with an LCP100 local control panel or a locally‐mounted switch for initiating a partial stroke test. Some applications require that the switch or local control panel be installed remotely from the DVC6200 SIS.

The length for wiring connected to the Auxiliary Input Terminals is limited by capacitance. For proper operation of the Auxiliary Input Terminals capacitance should not exceed 100,000 pF. As with all control signal wiring, good wiring practices should be observed to minimize adverse effect of electrical noise on the Aux Switch function.

Example Calculation: Capacitance per foot or per meter is required to calculate the length of wire that may be connected to the Aux switch input. The wire should not exceed the capacitance limit of 100,000 pF. Typically the wire manufacturer supplies a data sheet which provides all of the electrical properties of the wire. The pertinent parameter is the highest possible capacitance. If shielded wire is used, the appropriate number is the “Conductor to Other Conductor & Shield” value.

Example — 18AWG Unshielded Audio, Control and Instrumentation Cable

Manufacturer's specifications include:

Nom. Capacitance Conductor to Conductor @ 1 KHz: 26 pF/ft Nom. Conductor DC Resistance @ 20 Deg. C: 5.96 Ohms/1000 ft Max. Operating Voltage - UL 200 V RMS (PLTC, CMG),150 V RMS (ITC) Allowable Length with this cable = 100,000pF /(26pF/ft) =3846 ft

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 5 V, 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.

Guided Setup

Field Communicator Configure > Guided Setup (2‐1)

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

D Device Setup—This procedure is used to configure actuator and valve information, calibrate the valve assembly, and

assign the tuning set for the valve assembly.

D Performance Tuner—This procedure executes a simple step response test and then calculates a recommended set of

gain values based on the response of the control valve. See page 22 for additional information.

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.

Refer to table 3‐2 for possible configurations for a digital valve controller operated by a 4‐20 mA input current (point‐to‐point mode), and table 3‐3 for possible configurations for a digital valve controller operated by a 0‐24 VDC power supply (multi‐drop mode).

Mode and Protection

Field Communicator Configure > Manual Setup > Mode and Protection (2‐2‐1)

Instrument Mode

There are two instrument modes for the DVC6200 SIS; In Service or Out of Service. In Service is the normal operating mode such that the instrument follows the 420 mA or 24 VDC control signal. Out of Service is required in some cases to modify configuration parameters or to run diagnostics.

Note

Some changes that require the instrument to be taken Out Of Service will not take effect until the instrument is placed back In Service or the instrument is restarted.

Write Protection

There are two Write Protection modes for the DVC6200 SIS: Not Protected or Protected. Protected prevents configuration and calibration changes to the instrument. The default setting is Not Protected. Write Protection can be changed to Protected remotely. However, to change Write Protection to Not Protected, you must have physical access to the instrument. The procedure will require you to press a button ( ) on the terminal box as a security measure.

Instrument

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

Follow the prompts on the Field 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 Field Communicator establishes contact with the digital valve controller at power‐up.

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

D Description—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.

Page 18

Configuration

April 2016

For the Field 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.

Instruction Manual

D103557X012

Serial Numbers

D Instrument Serial Number—Enter the serial number on the instrument nameplate, up to 12 characters.

D Valve Serial Number—Enter the serial number for the valve in the application with up to 12 characters.

Units

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

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

digital valve controller's printed wiring board.

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

Terminal Box

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. Alternatively, the auxiliary terminals can be configured to support the local control panel.

Spec Sheet

The Spec Sheet provides a means to store the entire control valve specifications on board the DVC6200 SIS.

Edit Instrument Time

Permits setting the instrument clock. When alerts are stored in the alert record, the record includes the time and date. The instrument clock uses a 24‐hour format.

Travel/Pressure Control

Field Communicator Configure > Manual Setup > Travel/Pressure Control (2‐2-3)

End Point Pressure Control (EPPC)

D EPPC 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.

D EPPC 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.

D EPPC 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.

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 3‐1 or you can select a custom characteristic. Figure 3‐1 shows the relationship between the travel target and ranged set point for the fixed input characteristics, assuming the Zero Power Condition is configured as closed.

You can specify 21 points on a custom characteristic curve. Each point defines a travel target, in % of ranged travel, for a corresponding set point, in % of ranged set point. Set point values range from -6.25% to 106.25%. Before modification, the custom characteristic is linear.

D Custom Characterization

To define a custom input character, from the Characterization menu select Custom Characterization. Select the point you wish to define (1 to 21), then enter the desired set point value. Press Enter then enter the desired travel target for the corresponding set point. When finished, select point 0 to return to the Characterization menu.

With input characterization you can modify the overall characteristic of the valve and instrument combination. Selecting an equal percentage, quick opening, or custom (other than the default of linear) input characteristic

Page 20

Configuration

Instruction Manual

D103557X012

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. In firmware 4 this parameter should be set to 0.

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. In firmware 4 this parameter should be set to 0.

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. In firmware 4 this parameter should be set to 0.

Travel Cutoffs

D Hi Cutoff Point—This is the point within the calibrated travel range above which the cutoff is in effect. When using

cutoffs, a Cutoff Hi of 50% is recommended to ensure valve goes fully open.

D Lo Cutoff Point—This is the point within the calibrated travel range below which the cutoff is in effect. When using

cutoffs, a Cutoff Lo of 50% is recommended to help ensure maximum shutoff seat loading.

Tuning

Travel Tuning

WARNING

Changes to the tuning set may cause the valve/actuator assembly to stroke. To avoid personal injury and property damage caused by moving parts, keep hands, tools, and other objects away from the valve/actuator assembly.

D Travel Tuning Set

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

Table 3‐4 lists the proportional gain, velocity gain and minor loop feedback gain values for preselected tuning sets.

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 routine 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 3‐5 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.

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 Performance 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.

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.

D Stabilize/Optimize

WARNING

During Stabilize/Optimize the valve may move, causing process fluid or pressure to be released. To avoid personal injury and property damage caused by the release of process fluid or pressure, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the process fluid.

Stabilize/Optimize permits you to adjust valve response by changing the digital valve controller tuning. During this routine, the instrument must be out of service; however, the instrument will respond to setpoint changes.

If the valve is unstable, select Decrease Response to stabilize valve operation. This selects the next lower tuning set (e.g., F to E). If the valve response is sluggish, select Increase Response to make the valve more responsive. This selects the next higher tuning set (e.g., F to G).

If after selecting Decrease Response or Increase Response the valve travel overshoot is excessive, select Decrease 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.

Integral Settings

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

to eliminate friction induced limit cycles around the Primary Setpoint when the integrator is active. The Dead Zone is configurable from 0% to 2%, corresponding to a symmetric window from 0% to +/-2% around the Primary Setpoint. Default value is 0.25%.

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.

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 SIS housing) has to remain within this range throughout the entire valve travel. The linear magnet assemblies are symmetrical. Either end may be up.

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 SIS to a system running ValveLink software.

2. Disable the following parameters:

D Travel Deviation Alert - set to 125%.

D End Point Pressure Control - disable

D Partial Stroke Pressure Limit - disable by setting the appropriate value shown in table 3‐7.

SIS Options

D Auto Test Interval—This is the interval of time (in days) between partial stroke tests that are automatically run by the

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

D LoopInitiated PST—When this feature is enabled, the digital valve controller will run a partial stroke test if the loop

current is set to within +/0.5% of the PST trip point. The loop current must remain at that point for the duration of the test. To abort the test, the loop current must be returned to the normal or tripped current. This feature is disabled by default. This feature is not available when a looppowered local control panel is installed.

PST Trip Point (ETT) - This is the point at which the loop current must be set to run a partial stroke test for energizetotrip applications. This value is not configurable.

PST Trip Point (DETT) - This is the point at which the loop current must be set to run a partial stroke test for deenergizetotrip applications. This value is not configurable.

D Device Power Up Reset—This defines the power up behavior of the DVC6200 SIS. Auto Reset allows the valve to

track the command signal when power is applied to the device. Manual Reset will lock the device in its safety position until the digital valve controller is reset.

If Manual Reset is selected, its state can be determined from the status monitor by monitoring the Locked In Safety Position alert.

When Auxiliary Terminal Action is set to SIS Local Control Panel, Device Power Up is set to Manual Reset and cannot be changed to Auto Reset.

The reset signal depends on how the AUX terminals are configured. If configured for SIS Local Control Panel, the digital valve controller can be reset by pressing the button next to the green light on the LCP100. If configured as Push Button Partial Stroke, the digital valve controller can be reset by shorting the AUX terminals for more than 3 seconds but less than 10 seconds. The device cannot be reset from the AUX terminals if they are configured otherwise.

D Action on Failed Test—This displays the action taken by the instrument if a communication timeout occurs. Values

are Ramp Back or Step Back.

Outputs

Field Communicator Configure > Manual Setup > Outputs (2-2-6)

Output Terminal Configuration

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

Enabled.

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

Page 31

Instruction Manual

D103557X012

configured as a transmitter, the output can be configured to drive high (22.5 mA) or low (3.6 mA). When configured as a switch, the output can be configured to drive Closed or Open.

Note

On loss of positioner power, the switch circuit will always go to the open state. However, on loss of positioner power, the transmitter output will continue to operate as long as the transmitter circuit is still powered and functioning.

Configuration

April 2016

Switch Configuration

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, Valve Stuck, LCP Tripped, SIS Diagnostic Credit, or Diagnostic in Progress.

D Switch Closed—This configures the action of the switch. The choices are: Below Trip Point / Alert Not Active or

Above Trip Point / Alert Active.

HART Variable Assignments

Instrument variables can be reported via four different HART variable assignments. The Primary Variable is always configured as Analog Input. However, the remaining three variables have additional options as listed below.

Primary Variable (PV) Analog Input

Secondary Variable (SV) Travel, Travel Setpoint, Pressure A, Pressure B, Pressure 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

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.

Page 32

Configuration

April 2016

Instruction Manual

D103557X012

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.

Alert Setup

Field Communicator Configure > Alert Setup (2‐3)

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 3‐2. 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.

Section 4 Calibration 44

Calibration Overview

When a DVC6200 SIS digital valve controller is ordered as part of a control valve assembly, the factory mounts the digital valve controller on the actuator and connects the necessary tubing, then sets up and calibrates the controller.

For digital valve controllers that are ordered separately, recalibration of the analog input or pressure sensors generally is unnecessary. However, after mounting on an actuator, perform the initial setup then calibrate travel by selecting 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 36

Manual Travel Calibration - see page 37

Pushbutton Calibration - see page 38

Pressure Sensor Calibration - see page 39

Analog Input Calibration - see page 40

Relay Adjustment - see page 41

PST Calibration - see page 43

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 41.

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.

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 Field 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 Field Communicator display to calibrate the instrument's travel in percent.

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

If another adjustment is required, repeat step 7. Otherwise, select Done and go to step 8.

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

Pushbutton Calibration

A pushbutton near the wiring terminals in the terminal box provides a quick means to autocalibrate the instrument. The button must be pressed for 3 to 10 seconds. Autocalibration will move the valve through the full range of travel whether the Instrument Mode is In Service or Out of Service. However, if the Write Protection is Protected, this button will not be active. To abort, press the button again for 1 second. The calibration button is disabled by default. To enable it, go to Manual Setup > Instrument > Calibration Button.

Note

The autocal pushbutton will not be active if the instrument is Locked in Safety.

This calibration procedure is recommended whenever the I/P converter or pneumatic relay is replaced. Do not use the pushbutton calibration for initial calibration when mounting the instrument on an actuator, or if the printed wiring board assembly was replaced.

If you suspect calibration has changed due to drift, first perform a Valve Signature diagnostic test using ValveLink software to capture the 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 Field 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 Field Communicator is between 50 and 70% of supply pressure. This adjustment is very sensitive. Be sure to allow the pressure reading to stabilize before making another adjustment (stabilization may take up to 30 seconds or more for large actuators).

Low bleed relay stabilization may take approximately two minutes longer than the standard relay.

D Variable Out of Range—This alert 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.

D Field Device Malfunction—This alert is active if the pressure, position, or temperature sensors are providing invalid

readings.

D Internal Sensor Out of Limits—This alert is active if there is a problem with either the pressure sensor or the printed

wiring board assembly.

D Travel Sensor Failure—This alert 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.

D Temperature Sensor Failure—This alert 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.

D Pressure Sensor Failure—This alert is active if any of the 3 pressure sensor readings are outside the range of 24.0 to

125.0% of the calibrated pressure for more than 60 seconds. If this alert is active, check the instrument supply pressure, ensure the printed wiring board assembly is properly mounted onto the module base assembly, and ensure the pressure sensor orings are properly installed. If the alert persists after restarting the instrument, replace the printed wiring board assembly.

D Minor Loop Sensor Alert—This alert is active if the pneumatic relay position reading is outside the valid range. If the

alert persists, replace the printed wiring board.

D Loop Current Validation Alert—This alert is active if the loop current is significantly out of range, or if there is a

problem with the analog circuit electronics. If this alert is active, restart the instrument with the loop current verified to be in the 420 mA range. If the alert persists, replace the printed wiring board.

Note

If the control system is known to output current 24 mA or above, Shutdown on Loop Current Validation should not be enabled.

D Output Circuit Communication Failure—This alert is active if the output circuit is not responding. If configured as a

position transmitter output, first make sure the transmitter circuit is powered. If the alert persists, make sure the DIP switch on the main electronics matches the configuration of the OUT terminals. If the alert is still active, replace the main electronics.

D Instrument Time is Approximate Alert—This alert is active if the instrument has been powered down since the last

time the instrument clock was set. To clear the alert, reset the instrument time.

D SIS Program Flow Failure—This alert is active if the firmware is not performing the expected series of calculations.

D SIS Hardware Failure—This alert is active if a demand has occurred, but the electronics hardware failed to take

control of the I/P drive.

D LCP Communication Failure—This alert is active if the AUX terminals are configured for use with the local control

panel, but communication between the DVC6200 SIS and LCP is not occurring.

D Travel Alert Lo Lo—This alert is active when the Travel is below the Travel Alert Lo Lo Point. Once the alert is active,

the alert will clear when the Travel exceeds the Travel Alert Lo Lo Point plus the Travel Alert Deadband.

D Travel Cutoff Hi Alert—This alert is active when the Travel exceeds the Hi Cutoff Point.

D Travel Cutoff Lo Alert—This alert is active when the Travel falls below the Lo Cutoff Point.

D Integrator Saturated High Alert—This alert is active if the instrument integrator is saturated at the high extreme.

D Integrator Saturated Low Alert—This alert is active if the instrument integrator is saturated at the low extreme.

D Pressure Fallback Active Alert—This alert is active when the instrument has detected a problem with the travel

feedback and is now controlling the output like an I/P transducer.

CAUTION

If a Valve Stuck alert is active, there may be potential energy stored in the valve and actuator assembly. Sudden release of this energy may cause the valve to suddenly open or close, resulting in equipment damage.

D Valve Stuck—A partial stroke test has failed.

If the valve sticks while performing the partial stroke test, the digital valve controller will not fully exhaust or fill the actuator pressure in its attempt to complete the partial stroke. Rather, the instrument will abort the test and this alert will be active. It is recommended that the Travel Deviation alert also be enabled and configured. The Valve Stuck alert will be active if either the Travel Deviation alert is active or if the actuator pressure reaches the Partial Stroke Pressure Limit.

Travel History

D Cycle Count High Alert—This alert is active if the Cycle Counter exceeds the Cycle Count Alert Point. The Cycle Count

records the number of times the travel changes direction when it is outside of the deadband. To clear the alert, set the Cycle Counter to a value less than the alert point.

D Travel Accumulator High Alert—This alert 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.

Note

The Cycle Count / Travel Accumulator Deadband applies to both the Cycle Count High Alert and the Travel Accumulator High Alert.

The deadband is the percent (%) of ranged travel around a travel reference point. The travel reference point gets reestablished 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.

Stroke Valve

Follow the prompts on the Field Communicator display to select from the following:

D Done—Select this if you are done. All ramping is stopped when DONE is selected.

D Ramp Open—ramps the travel toward open at the rate of 1.0% per second of the ranged travel.

D Ramp Closed—ramps the travel toward closed at the rate of 1.0% per second of the ranged travel.

D Ramp to Target—ramps the travel to the specified target at the rate of 1.0% per second of the ranged travel.

D Step to Target—steps the travel to the specified target.

Partial Stroke Test

WARNING

During the partial stroke test the valve will move. To avoid personal injury and property damage caused by the release of pressure or process fluid, when used in an application where the valve is normally closed, provide some temporary means of control for the process.

The Partial Stroke Test allows DVC6200 SIS digital valve controllers 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 in its normal (not tripped) state. For energizetotrip (ETT) applications, the normal state is 4 mA. For deenergizetotrip (DETT) applications, the normal state is 20 mA (pointtopoint mode) or 24 VDC (multidrop mode).

When enabled, a partial stroke test may be initiated by the device (as a scheduled, automatic partial stroke test), a local pushbutton, the LCP100, a Field Communicator, or ValveLink software.

D Automatic (Scheduled)

The Auto Partial Stroke Test allows the partial stroke test to be scheduled by the DVC6200 SIS. The test is scheduled in number of hours between tests. Any power cycle will reset the test clock timer.

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 10 seconds and then opened. To abort the test, close the contacts for 1 second. The last set of diagnostic data is stored in the instrument memory for later retrieval via ValveLink software.

Demand Mode Tests

The following steps assume the use of single acting spring and diaphragm actuators or double‐acting spring assist piston actuators.

Perform the following steps to confirm valve operation:

D Point‐to‐Point Mode (DVC6200 SIS powered with 4-20 mA current source)

If the DVC6200 SIS is in series with a solenoid valve,

1. Disconnect the power from the solenoid valve, but maintain the 20 mA current to the digital valve controller. The valve should move to its “fail safe” position.

2. Maintain power to the solenoid valve and adjust the current to the digital valve controller from 20 mA to 4 mA. The valve should move to its “fail safe” position.

3. Remove power from the solenoid valve and adjust the current to the digital valve controller from 20 mA to 4 mA. The valve should go to its “fail safe” position.

If a solenoid is not used with a DVC6200 SIS,

1. Adjust the current to the digital valve controller from 20 mA to 4 mA. The valve should move to its “fail safe” position.

Note

The above tests are applicable for single‐acting direct relay A and C. If single‐acting reverse relay B is used adjust the current from 4 mA (normal state) to 20 mA (trip state).

D Multi‐drop Mode (DVC6200 SIS is powered by a 24 VDC power source)

If the DVC6200 SIS is pneumatically in series with a solenoid valve, and shares a single power source,

1. Disconnect power to both devices. The valve should go to its “fail safe” position.

If the DVC6200 SIS is pneumatically in series with a solenoid valve, with independent power sources,

1. Connect a 24 VDC power supply to the solenoid valve and a second 24 VDC power supply to the DVC6200 SIS.

2. Disconnect the solenoid valve power supply, but maintain the power supply to the DVC6200 SIS. The valve should go to its “fail safe” position quickly.

3. Maintain the power supply to the solenoid valve and disconnect the DVC6200 SIS power supply. The valve should go to its “fail safe” position, although not as quickly as it does in the previous scenario.

If DVC6200 SIS is alone, without a solenoid valve,

1. Disconnect power to the digital valve controller. The valve should go to its “fail safe” position.

Note

The above tests are applicable for single‐acting direct relay A and C.

Solenoid Valve Health Monitoring

The following steps assume the use of a single‐acting actuator with a solenoid valve installed. The DVC6200 SIS digital valve controller, with single‐acting, direct relay C, must be powered separately from the solenoid. The unused output of the DVC6200 SIS must be connected between the solenoid and the actuator as described in the Installation section. The relay configuration selection must be “special application” and ValveLink software must have the triggered profile enabled.

1. When allowed by the Logic Solver, momentarily remove and then restore power to the solenoid (typically 100 to 200 milliseconds). This process should occur quickly enough that the valve assembly does not move when the solenoid is de‐energized.

2. With ValveLink software, upload the diagnostic data from the triggered profile menu.

3. Examine the graph and observe that there was a change in the pressure reading downstream of the solenoid.

Maintenance and Troubleshooting

April 2016

Section 6 Maintenance and Troubleshooting66

The DVC6200 SIS digital valve controller enclosure is rated Type 4X and IP66, therefore periodic cleaning of internal components is not required. If the DVC6200 SIS 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 SIS digital valve controller:

D Always wear protective clothing, gloves, and eyewear.

D Do not remove the actuator from the valve while the valve is still pressurized.

D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the

actuator cannot suddenly open or close the valve.

D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure

from both sides of the valve.

D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.

D Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

D Vent the pneumatic actuator loading pressure and relieve any actuator spring precompression so the actuator is not

applying force to the valve stem; this will allow for the safe removal of the stem connector.

WARNING

When using natural gas as the supply medium, or for explosion proof applications, the following warnings also apply:

D Remove electrical power before removing the housing cap. Personal injury or property damage from fire or explosion

may result if power is not disconnected before removing the cap.

D Remove electrical power before disconnecting any of the pneumatic connections.

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

Page 58

Maintenance and Troubleshooting

CAUTION

To avoid affecting performance of the instrument, take care not to damage the module base seal or guide surface. Do not bump or damage the bare connector pins on the PWB assembly. Damaging either the module base or guide surface may result in material damage, which could compromise the instruments ability to maintain a pressure seal.

Note

To avoid affecting performance of the instrument, inspect the guide surface on the module and the corresponding seating area in the housing before installing the module base assembly. These surfaces must be free of dust, dirt, scratches, and contamination.

Ensure the module base seal is in good condition. Do not reuse a damaged or worn seal.

1. Ensure the module base seal (key 237) is properly installed in the housing (key 1). Ensure the O‐ring (key 12) is in place on the module base assembly.

2. Connect the travel sensor and terminal box cable assemblies to the PWB assembly (key 50). Orientation of the connector is required.

3. Insert the module base (key 2) into the housing (key 1).

4. Install three socket head screws (key 38) in the module base into the housing. If not already installed, press three retaining rings (key 154) into the module base. Evenly tighten the screws in a crisscross pattern to a final torque of 16 NSm (138 lbfSin).

WARNING

Personal injury, property damage, or disruption of process control can result if the cable assemblies/wiring are damaged when attaching the cover to the module base assembly

Ensure that the cable assemblies/wiring are positioned in the cavity of the module base so they do not get compressed or damaged when attaching the cover to the module base assembly in step 5.

5. Attach the cover (key 43) to the module base assembly.

Submodule Maintenance

The module base of the DVC6200 SIS contains the following submodules: I/P converter, PWB assembly, and pneumatic relay. If problems occur, these submodules may be removed from the module base and replaced with new submodules. After replacing a submodule, the module base may be put back into service.

To check the Voltage Available at the instrument, perform the following:

1. Connect the equipment in figure 2‐2 to the field wiring in place of the FIELDVUE instrument.

2. Set the control system to provide maximum output current.

3. Set the resistance of the 1 kilohm potentiometer shown in figure 2‐2 to zero.

4. Record the current shown on the milliammeter.

5. Adjust the resistance of the 1 kilohm potentiometer until the voltage read on the voltmeter is 10.0 volts.

6. Record the current shown on the milliammeter.

7. If the current recorded in step 6 is the same as that recorded in step 4 (± 0.08 mA), the voltage available is adequate.

8. If the voltage available is inadequate, refer to Wiring Practices in the Installation section.

Restart Processor

This is a “soft” reset of the device. This procedure can only be performed while the instrument is out of service. A soft reset will immediately put into effect changes that have been sent to the instrument. Also, if the device is configured to shutdown on an alert, the soft reset will clear the shutdown.

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.

+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 SIS Digital Valve Controller

The DVC6200 SIS digital valve controller housing contains the travel sensor, terminal box, pneumatic input and output connections and a module base that may be easily replaced in the field without disconnecting field wiring or tubing. The module base contains the following submodules: I/P converter, printed wiring board (pwb) assembly, and pneumatic relay. The relay position is detected by sensing the magnet on the relay beam via a detector on the printed wiring board. This sensor is used for the minor loop feedback (MLFB) reading. The module base can be rebuilt by replacing the submodules. See figures A‐3 and A‐4.

D103557X012

E1362

DVC6200 SIS digital valve controllers are loop‐powered instruments that provide a control valve position proportional to an input signal from the control room. The following describes a double‐acting digital valve controller mounted on a piston actuator.

The input signal is routed into the terminal box through a single twisted pair of wires and then to the printed wiring board assembly submodule where it is read by the microprocessor, processed by a digital algorithm, and converted into an analog I/P drive signal.

As the input signal increases, the drive signal to the I/P converter increases, increasing the I/P output pressure. The I/P output pressure is routed to the pneumatic relay submodule. The relay is also connected to supply pressure and amplifies the small pneumatic signal from the I/P converter. The relay accepts the amplified pneumatic signal and provides two output pressures. With increasing input (4 to 20 mA signal), the output A pressure always increases and the output B pressure decreases. The output A pressure is used for double‐acting and single‐acting direct applications. The output B pressure is used for double‐acting and single‐acting reverse applications. As shown in figure A‐3 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.

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 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.

Control Mode, Restart

Determines the instrument control mode after a restart. See Control Mode for the available restart control modes.

Controller

A device that operates automatically to regulate a controlled variable.

Current‐to‐Pressure (I/P) Converter

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

Cycle Counter

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

Cycle Counter Alert

Checks the difference between the Cycle Counter and the Cycle Counter Alert Point. Cycle Counter Alert is active when the cycle counter value exceeds the Cycle Counter Alert Point. It clears after you reset the Cycle Counter to a value less than the alert point.

Cycle Counter Alert Point

An adjustable value which, when exceeded, activates the Cycle Counter Alert. Valid entries are 0 to 4 billion cycles.

Cycle Counter Deadband

Region around the travel reference point, in percent of ranged travel, established at the last increment of the Cycle Counter. The deadband must be exceeded before a change in travel can be counted as a cycle. Valid entries are 0% to 100%. Typical value is between 2% and 5%.

Deviation

Usually, the difference between set point and process variable. More generally, any departure from a desired or expected value or pattern.

Drive Signal Alert

Checks the drive signal and calibrated travel. If one of the following conditions exists for more than 20 seconds, the Drive Signal Alert is active. If none of the conditions exist, the alert is cleared.

If Zero Power Condition = Closed

The alert is active when: drive signal <10% and calibrated travel >3% drive signal >90% and calibrated travel <97%

If Zero Power Condition = Open

The alert is active when: drive signal <10% and calibrated travel <97% drive signal >90% and calibrated travel >3%

Equal Percentage

A valve flow characteristic where equal increments of valve stem travel produce equal percentage changes in existing flow. One of the input characteristics available for a FIELDVUE Instrument. See also, Linear and Quick Opening.

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.

Instrument Level

Determines the functions available for the instrument.

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

Minimum Closing Time

Minimum time, in seconds, for the travel to decrease through the entire ranged travel. This rate is applied to any travel decrease. Valid entries are 0 to 400 seconds. Deactivate by entering a value of 0 seconds.

Minimum Opening Time

Minimum time, in seconds, for the travel to increase through the entire ranged travel. This rate is applied to any travel increase. Because of friction, actual valve travel may not respond in exactly the same time frame. Valid entries are 0 to 400 seconds. Deactivate by entering a value of 0 seconds.

Non‐Volatile Memory (NVM)

A type of semiconductor memory that retains its contents even though power is disconnected. NVM contents can be changed during configuration unlike ROM which can be changed only at time of instrument manufacture. NVM stores configuration restart data.

Parallel

Simultaneous: said of data transmission on two or more channels at the same time.

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.

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).

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 SIS has three pressure sensors: one to sense supply pressure and two to sense the output pressures.

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.

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.

Stroke Time

The DVC6200 SIS calculates the time it takes to fully stroke in the event of a demand and stores the last value. In order for the calculation to occur, the Travel Hi Hi and Travel Lo Lo alert points must be configured to 99% and 1% respectively. Stroke time can be read from the

device with ValveLink software

Stroking Time

The time, in seconds, required to move the valve from its fully open position to fully closed, or vice versa.

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.

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 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

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 Range

Travel, in percent of calibrated travel, that corresponds to the input range.

Travel Sensor

A device within the FIELDVUE instrument that senses valve stem or shaft movement. The travel sensor in the DVC6200 SIS 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.

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.

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.

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.
