Instrument Description

The DVC2000 digital valve controller is a communicating, microprocessor-based current-to-pneumatic valve positioner. It is designed to replace standard pneumatic and electro-pneumatic valve positioners.

In addition to the traditional function of converting an input current signal (4-20 mA) to a pneumatic output pressure, the DVC2000 digital valve controller communicates via a local display panel and/or via the HART® protocol. An option is available which provides isolated circuitry for two (2) integrated limit switches (for open/close valve indication) and a valve position transmitter (for separate valve position feedback).

Terminology

Instrument Level— There are four (4) levels of functionality available: AC, HC, AD and PD.

AC—This level provides the capability to setup and calibrate the positioner through the local user interface or the Field

Communicator.

HC—This level provides additional capability for advanced configuration of the positioner (such as travel limits/cutoffs, custom characterization, and minimum open/closing time). Also, information is available through the HART protocol for diagnostic alerts such as travel deviation, cycle count, and travel accumulation.

AD—This level provides advanced diagnostic capabilities for performance testing. When used with ValveLink software, instrument health can be evaluated with tests such as Valve Signature, step response and dynamic error band. The software program provides detailed analysis with graphics.

PD—This level provides automated, non-intrusive testing of the operating performance of the control valve assembly. When used with ValveLink affecting the process.

software, tests to isolate component degradation can be run on the valve assembly without

Local Interface— The DVC2000 comes standard with a Liquid Crystal Display (LCD) and four (4) pushbuttons. The local interface provides the capability to setup and calibrate the positioner and view basic diagnostic messages.

Magnet Assembly—This is the feedback component that is mounted directly to the valve stem. It supplies a magnetic field that is sensed by the digital valve controller.

Options Board—The DVC2000 digital valve controller is available with two (2) limit switches and a valve position transmitter. The options board includes the additional circuitry and terminations that are required to support these output signals.

Pole Piece—Inserted into the DVC2000 housing and protruding through the back of the instrument is a two-pronged fork that houses the magnetic sensor for position feedback.

Specifications

Specifications for the DVC2000 digital valve controller are shown in table 1‐1.

Detailed Setup and Calibration

July 2020

Section 2 Detailed Configuration and Calibration via HART Communication

2‐2‐

Detailed Setup

The DVC2000 digital valve controller has the capability to communicate via the HART protocol. This section describes the advanced features that can be accessed with the Field Communicator. Table 2‐1 lists the default settings for a standard factory configuration. Table 2‐2 provides the actuator information required to setup and calibrate the instrument.

Setting Modes

Field Communicator Setup & Diag > Detailed Setup > Mode (1-2-1)

Instrument Mode

You can change the instrument mode by selecting Instrument Mode from the Mode menu, or press the Hot Key and select Instrument Mode.

Instrument Mode allows you to either take the instrument Out Of Service or place it In Service. Taking the instrument Out Of Service allows you to perform instrument calibration and also allows you to change setup variables that affect control, provided the calibration/configuration protection is properly set. See Setting Protection.

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.

Control Mode

You can change the control mode by selecting Control Mode from the Mode menu, or press the Hot Key and select Control Mode.

Control Mode lets you define where the instrument receives its set point. Follow the prompts on the Field Communicator display to choose one of the following control modes: Analog or Digital.

Choose Analog if the instrument is to receive its set point over the 4-20 mA loop. Normally the instrument control mode is Analog.

Choose Digital if the instrument is to receive its set point digitally, via the HART communications link.

A third mode, Test, is also displayed. Normally the instrument should not be in the Test mode. The Field Communicator automatically switches to this mode whenever it needs to stroke the valve, for example during

Detailed Setup and Calibration

July 2020

D103176X012

calibration or stroke valve. 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 Control Mode then select either Analog or Digital.

Restart Control Mode

Restart Control Mode (Restart Cont Mode) lets you choose which operating mode you want the instrument to be in after a restart. Follow the prompts on the Field Communicator display to define the restart control mode as Resume Last, Analog, or Digital.

Restarting the Instrument

Restart resets the instrument in the same manner as when power to the instrument is interrupted. When Restart is issued, all of the newly entered configuration variables become active. Otherwise, they may not take effect until the instrument is placed In Service.

Burst Mode

Enabling burst mode provides continuous communication from the digital valve controller. Burst mode applies only to the transmission of burst mode data (analog input, travel target, pressure, and travel) and does not affect the way other data is accessed.

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.

There are four burst mode commands. Command 3 is recommended for use with the Rosemount Tri-Loop

™

HART-to-analog signal converter. The other three are not used at this time.

™

333 HART

Command 3 provides the following variables:

D Primary variable—analog input in % or mA,

D Secondary variable—travel target (valve set point) in % of ranged travel,

D Tertiary variable—output pressure in psig, bar, or kPa,

D Quaternary variable—travel in % of ranged travel.

To enable burst mode select Mode > Burst > Burst Enable. To send a burst mode command, select Burst Command. Burst mode must be enabled before you can change the burst mode command.

Follow the prompts on the Field Communicator to edit or view information in the following fields:

D Max Supply Press—Enter the maximum supply pressure in psi, bar, or kPa, depending on what was selected for

pressure units.

Note

If the actual measured pressure exceeds this setting by 25%, the Output A pressure measurement will not be displayed.

D 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.

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

D Zero Control Signal—Identifies whether the valve is fully open or fully closed when the input is 0%. If you are unsure

how to set this parameter, disconnect the current source to the instrument. The resulting valve travel is the Zero Control Signal. (With direct-acting digital valve controllers, disconnecting the current source is the same as setting the output pressure to zero.)

Setting Response

Field Communicator Setup & Diag > Detailed Setup > Response Control (1-2-6)

Follow the prompts on the Field Communicator to configure the following response control parameters:

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 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 2‐4 lists the proportional gain, velocity gain, and minor loop feedback gain values for preselected tuning sets.

D Damping Factor—If after selecting a tuning set the valve travel overshoot is excessive or unsatisfactory, the damping

factor allows you to either decrease damping to allow more overshoot, or increase damping to decrease the overshoot.

D Expert Tuning Gains—With Expert Tuning, you can specify the proportional gain, velocity gain, and minor loop

feedback gain.

D Input Char—Defines the relationship between the travel target and ranged set point. Ranged set point is the input to

the characterization function. If the zero control signal equals closed, then a set point of 0% corresponds to a ranged input of 0%. If the zero control signal equals open, a set point of 0% corresponds to a ranged input of 100%. Travel target is the output from the characterization function.

You can select from the three fixed input characteristics shown in figure 2‐2 or you can select a custom characteristic. Figure 2‐2 shows the relationship between the travel target and ranged set point for the fixed input characteristics, assuming the Zero Control Signal 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.

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).

D Custom Char Table—To define a custom input characteristic, s

elect Custom Char Table. 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 Response Control menu.

digital valve controller and is typically used with noisy or fast processes. The filter provides improved closed loop process control. To disable the filter, set the time constant to 0 seconds.

D Limits and Cutoff

Travel Limit Hi—Defines the high limit for the travel in percent (%) of ranged travel. It is the maximum allowable travel (in percent of ranged travel) for the valve. During operation, the travel target will not exceed this limit. When a Travel Limit High is set, the Travel Cutoff High is deactivated, since only one of these parameters can be active. Travel Limit High is deactivated by setting it to 125.0%.

Travel Limit Lo—Defines the low limit for the travel in percent (%) of ranged travel. It is the minimum allowable travel (in percent of ranged travel) for the valve. During operation, the travel target will not exceed this limit. When a Travel Limit Low is set, the Travel Cutoff Low is deactivated, since only one of these parameters can be active. Travel Limit Low is deactivated by setting it to -25.0%.

Travel Cutoff Hi—Defines the high cutoff point for the travel in percent (%) of ranged travel. Above this cutoff, the travel target is set to 123.0% of the ranged travel. When a Travel Cutoff High is set, the Travel Limit High is deactivated, since only one of these parameters can be active. Travel Cutoff High is deactivated by setting it to

125.0%.

Travel Cutoff Lo—Defines the low cutoff point for the travel. Travel Cutoff Low can be used to ensure proper seat load is applied to the valve. When below the travel cutoff low, the output is set to zero or to full supply pressure, depending upon the zero control signal. A Travel Cutoff Low of 0.5% is recommended to help ensure maximum shutoff seat loading.

When a Travel Cutoff Low is set, the Travel Limit Low is deactivated, since only one of these parameters can be active. Travel Cutoff Low is deactivated by setting it to -25.0%.

D Min Open/Close

Min Opening Time—Minimum Opening Time is configured in seconds and defines the minimum time for the travel to increase the entire ranged travel. This rate is applied to any travel increases. A value of 0.0 seconds deactivates this feature and allows the valve to stroke open as fast as possible. This parameter should be set to 0 in firmware 1, 2, 3, and 4.

Min Closing Time—Minimum Closing Time is configured in seconds and defines the minimum time for the travel to decrease the entire ranged travel. This rate is applied to any travel decreases. A value of 0.0 seconds deactivates this feature and allows the valve to stroke closed as fast as possible. This parameter should be set to 0 in firmware 1, 2, 3, and 4.

D Integral Settings

Enab Int Control—Select Yes or No

Integral Gain—By setting this value to 0.0 the positioner integrator is disabled. Any other value will provide reset

action to improve static performance.

Integral Dead Zone—When the travel target and actual target deviate by less than this amount, the integrator is automatically disabled. This prevents the positioner integrator from fighting with the process controller integrator which may result in valve oscillation.

Field Communicator Calibrate > Calibrate > Auto Tuner (1-4-5)

The auto tuner is used to optimize digital valve controller tuning. It can be used on most sliding-stem and rotary designs, including Fisher and other manufacturers' products. Moreover, because the auto tuner can detect internal instabilities before they become apparent in the travel response, it can generally optimize tuning more effectively than manual tuning.

Select Analog In Calib from the Calibrate menu, then follow the prompts on the Field Communicator display to calibrate the analog input sensor.

1. Set the current source to the target value shown on the display. The target value is the Input Range Low value. Press OK.

2. The following message appears:

Use Increase and Decrease selections until the displayed current matches the target.

Press OK when you have read this message.

3. The value of the Analog Input appears on the display. Press OK to display the adjustment menu.

4. From the adjustment menu, select the direction and size of adjustment to the displayed value. Selecting large, medium, and small adjustments causes changes of approximately 0.4 mA, 0.04 mA, and 0.004 mA, respectively. If the displayed value does not match the current source, press OK, then repeat this step (step 4) to further adjust the displayed value. When the displayed value matches the current source, select Done and go to step 5.

5. Set the current source to the target value shown on the display. The target value is the Input Range High value. Press OK.

7. The value of the Analog Input appears on the display. Press OK to display the adjustment menu.

8. From the adjustment menu, select the direction and size of adjustment to the displayed value. Selecting large, medium, and small adjustments causes changes of approximately 0.4 mA, 0.04 mA, and 0.004 mA, respectively. If the displayed value does not match the current source, press OK, then repeat this step (step 8) to further adjust the displayed value. When the displayed value matches the current source, select Done and go to step 9.

9. Place the instrument In Service and verify that the analog input displayed matches the current source.

Note

Analog Input Calibration can also be peformed using the Local Operator Interface, as decribed in the procedure below.

Instruction Manual

D103176X012

Using the Local Operator Interface to perform Analog Input Calibration

Refer to step 6 of the Local Interface Flow Chart on page 58 of this manual.

Connect a variable current source to the instrument +11 and -12 terminals. From the home screen, press the DOWN (B) arrow key five times and then press the RIGHT (") arrow key. Acknowledge the warning if you are sure that you want to proceed.

1. Adjust the variable current source to 4 mA.

2. Press the RIGHT (") arrow key

3. Adjust the variable current source to 20 mA.

4. Press the RIGHT (") arrow key.

If you want to keep this calibration, select SAVE AND EXIT. If you exit without saving, the last saved configuration data will be restored.

Auto Calibrate Travel

1. The auto calibration procedure is automatic. It is completed when the Calibrate 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 beam position sensor.

Adjusting the minor loop feedback bias is done around mid travel. The valve position is briefly moved back and forth to determine the relay beam position at quiescence. Essentially, it establishes the zero point for the Minor Loop Feedback circuit. The back and forth motion is performed to account for hysteresis.

Instruction Manual

D103176X012

Detailed Setup and Calibration

Section 4 Maintenance and Troubleshooting4‐4‐

The DVC2000 digital valve controller has the capability to provide predictive maintenance information through the use of ValveLink software. This software allows you to pinpoint instrument and valve problems without disrupting the process. For information on using ValveLink software, see the ValveLink software quick start guide (D102813X012

WARNING

Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before performing any maintenance procedures on the the DVC2000 digital valve controller:

D Always wear protective clothing, gloves, and eyewear when performing any maintenance procedures to avoid personal

injury or property damage.

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 control valve.

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

pressure from both sides of the control 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.

CAUTION

When replacing components, use only components specified by the factory. Always use proper component replacement techniques, as presented in this manual. Improper techniques or component selection may invalidate the approvals and the product specifications, as indicated in table 1‐1 and may also impair operations and the intended function of the device.

Troubleshooting

What is a healthy unit?

In order to troubleshoot the DVC2000 digital valve controller, it is critical to understand how a healthy unit is supposed to behave. Below is a list of behaviors you should see if the instrument is performing well.

D LCD correctly displaying characters

D Pushbuttons allow navigation

D Valve travels full stroke

D No diagnostics messages

D No alerts or alarms

D Hall sensor within the valid range of travel on the magnet assembly

D Slight audible air venting

D Minimal overshoot

D Quick response

D Functionality matches the tier level

What are the observable symptoms?

The next thing to do is to identify the symptoms of the unhealthy unit. Are there any obvious discrepancies that can be identified? Work through the following items to help gather information about the faulty behavior and identify the core problem(s). Also see the DVC2000 Troubleshooting Checklist on page 47.

1. Check the relay pressure range.

There are two available relays for the DVC2000:

D Low pressure: 0-3.4 bar (0-49 psi) — white label

D High pressure: 3.5-7 bar (50-100 psi) — green label

The supply pressure feeding the instrument must fall within the rated pressure range of the installed relay for proper operation.

2. Check the instrument protection (LCD via pushbuttons and Configure/Calibrate via HART)

3. Check for local device diagnostic messages

Instruction Manual

D103176X012

4. Check the alerts via HART

5. Check the feedback setup

Is the pole piece on the DVC2000 housing within the valid travel range of the feedback array?

6. Observe the stem movement and pressure delivery

Maintenance and Troubleshooting

Determine the logical causes.

With the discrepancies identified, logic can now be applied to isolate the component that is in need of repair or replacement. There are seven main categories of problems:

1. Wiring and Terminations

2. Air Supply

3. Electronics

4. Firmware

5. Pneumatics

6. Travel feedback

7. Mounting

July 2020

Repair or replace the faulty components.

By isolating the problem to one of these categories, component replacement or repair becomes simple and straightforward. Refer to component replacement instructions earlier in this section.

Principle of Operation

July 2020

Appendix A Principle of OperationA‐1‐

DVC2000 Operation

The DVC2000 digital valve controller uses a traditional 4-20 mA input signal and converts it into a pneumatic output pressure that is delivered to the control valve actuator. Accurate control of the position of the valve is enabled by valve stem position feedback. The way in which the DVC2000 accomplishes this is through a two-stage positioner design. Refer to figure A‐1 for a block diagram of the positioner operation.

AMPLIFIER

A traditional 4-20 mA signal provides the set point and power to the instrument. At the same time, the HART protocol provides instrument and process data through digital communications. The instrument receives this set point and positions the valve where it needs to be.

D The input signal provides electrical power and the set point simultaneously. It is routed into the terminal board

through a twisted pair of wires. The terminal board contains the termination points for the loop signal (+11/-12). If the options board is installed, an additional options board set includes additional terminals for the transmitter output (+31/-32), switch #1 output (+41/-42), and switch #2 output (+51/-52).

D The input signal is then directed to the main electronics board assembly where the microprocessor runs a digital

control algorithm resulting in a drive signal to the I/P converter.

Principle of Operation

July 2020

Instruction Manual

D103176X012

D The I/P converter assembly is connected to supply pressure and converts the drive signal into a pressure signal. The

I/P converter is the pre-amplifier stage in the two-stage positioner design. This component enables high static gain for responsiveness to small changes in the input signal.

D The I/P output is sent to the pneumatic relay assembly. The relay is also connected to supply pressure and amplifies

the small pressure signal from the I/P converter into a larger pneumatic output signal used by the actuator. The pneumatic relay is the power amplifier stage in the two-stage positioner design. This component enables superior dynamic performance with minimal steady-state air consumption.

D A sensor on the printed wiring board measures the motion of the small valve inside the pneumatic relay. This

measurement is used for minor loop feedback to the control algorithm resulting in stable, robust tuning.

D The change in relay output pressure to the actuator causes the valve to move.

D Valve position is sensed through the non-contact, linkage-less feedback sensor. There are no moving linkages and

the DVC2000 is physically separated from the valve stem through the use of a magnetic Hall effect sensor. A magnetic array is mounted to the valve stem and the sensor is embedded in the DVC2000 housing. The sensor is electrically connected to the printed wiring board to provide a travel feedback signal used in the control algorithm.

The valve continues to move until the correct position is attained.

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.

Byte

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

Control Mode, Restart

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

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 70‐2‐1991 and IEC 534‐4.

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.

Pressure Sensor

A FIELDVUE instrument internal device that senses pneumatic pressure. DVC2000 digital valve controllers have one actuator pressure sensor.

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 375 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.

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

The time constant, in seconds, for the first‐order input 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.

Quick Opening

A valve flow characteristic where most of the change in flow rate takes place for small amounts of stem travel from the closed position. The flow characteristic curve is basically linear through the first 40 percent of stem travel. One of the input characteristics available for a FIELDVUE Instrument. See also, Equal Percentage and Linear.

Random Access Memory (RAM)

A type of semiconductor memory that is normally used by the microprocessor during normal operation that permits rapid retrieval and storage of programs and data. See also Read Only Memory (ROM) and Non‐Volatile Memory (NVM).

Rate

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 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 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 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 Sensor

A device within the FIELDVUE instrument that senses valve stem or shaft movement.

Tuning

The adjustment of control terms or parameter values to produce a desired control effect.
