  • Page 39: Fail Safe Mode

    Fail Safe Mode The SVI does not go to failsafe mode if it is functioning normally. If a problem occurs and causes the SVI to go to the fail-safe mode, the SVI will attempt to drive the internal I/P to either high or low output based on SVI's failsafe configuration and the appropriate failure statuses are set in the SVI.

  • Page 40: Chapter 7: Normal Operating Mode

    Chapter 7: Normal Operating Mode SVI functions in normal operating, manual operating, configuration, calibration, diagnostic and fail-safe modes. Correspondingly, ValVue has various windows to interface with these different modes. In the normal operating mode, the SVI controlled valve responds to the 4-20 mA input signal directly if the SVI is configured as a positioner only.

  • Page 41: Reading Configuration And Calibration Data

    The bar graph shows the valve moving towards the position setpoint (setpoint is displayed as a triangle) in a transient state and how closely the valve matches its setpoint in a steady state. A typical deviation between valve position and its setpoint is less than 0.2% plus dead zone if the valve and positioner are functioning properly.

    • Quick Opening: The quick opening characterization is the inverse to the Equal Percentage (50) characterization curve. • Custom Characterization: A custom characterization defines the relationship between the input signal and the output position of the valve. Selecting this option will display an additional window where you can configure a characterization curve with 10 adjustable segments to fit your needs.

  • Page 54: Custom Linearization

    Custom Linearization When SVI is mounted on a reciprocating valve, linkage configuration may cause a small non-linearity in the valve position measured by the SVI position sensor versus actual valve position. This non-linearity is usually insignificant in a closed loop system and has the least effect on the closed loop performance. Therefore, it is usually unnecessary to correct this non-linearity.

  • Page 55: Local Button Lock

    The compound linkage has two lever segments attached at one end to the pivot (the position sensor in the SVI) and the other end to the valve stem pickup point. In order to compute the proper correction curve, the user must enter the stroke length, first lever segment length (L1), second lever segment length (L2), the distance from the pivot to the valve stem pickup (L3), and the valve position at horizon- tal.

  • Page 56: Tight Shutoff And Position Limits

    Tight Shutoff and Position Limits • Tight Shutoff Below (%): When selected, if the valve position setpoint is below the tight shutoff value (entered in the edit box to the right), full supply pressure or atmosphere pressure is supplied to the actuator as needed to close the valve with maximum seating force available.

  • Page 59: Positioner Error

    Positioner Error The user may configure how position errors are handled. A position error occurs when the valve posi- tion differs from the requested position by more than the Position Error Band for more than the position error Time 1. When this occurs, a status flag is set which is reported during the next HART message. The user must send a Read Status message to find out the cause of the status flag.

  • Page 60: Chapter 10: Calibration Mode

    Chapter 10: Calibration Mode Calibration mode is used to scale and calibrate analog inputs, valve position, output pressure and tune valve position controller. In this mode, the valve no longer responds to the 4-20 mA input signal. Some calibrate functions stroke the valve over its CAUTION full range.

  • Page 61: Range Page

    Range Page The Range page is displayed when entering calibration mode. The Range page allows the user to enter the low and high range values for the primary input signal, as well as remote setpoint and process vari- able if the built-in process controller is enabled (see Chapter 16: Controller Calibration) and allows auto- matic and manual calibration of the valve position sensor.
  • Page 62 Range Calibration Range calibration moves the valve over its entire WARNING stroke. Isolate the valve from the process prior to calibration. Through ValVue, the SVI position sensor can be calibrated either automatically or manually using the Auto Stop Limits or Manual Stop Limits method. The supply pressure must be at least 5 psi above the upper spring range of the valve so that mechanical stops can be reached by exhausting and filling the valve actuator.

  • Page 63: Tuning Page

    Tuning Page Autotune moves the valve over its entire stroke. WARNING Isolate the valve from the process prior to Autotune.

  • Page 67: Signal Calibration Page

    Signal Calibration Page The Signal Calibration page (figure 42) appears when clicking the Signal Cal. Tab in the SVI Calibration window. This page allows the user to re-calibrate the primary signal, the output pressure sensors, and the secondary signal if it is connected. These sensors are calibrated at the factory and do not usually require re-calibration.
  • Page 68 Calibrating the primary signal can be done most easily with a variable current source. Calibrating the secondary signal can be done most easily with a 1 - 5 voltage source or a variable current source with a 250 Ohm resistor across the A and B terminals in the SVI connection entry. Changing the value of the resistor calls for re-calibration of the secondary signal, since the secondary signal sensor actually meas- ures voltage across the resistor rather than current.

  • Page 69: Chapter 11: Diagnostic Mode

    Chapter 11: Diagnostic Mode Introduction Diagnostic mode allows the user to run several useful procedures that provide information about the SVI installed valve and its performance. Previous test data can be retrieved and graphically displayed in the diagnostic mode when running ValVue in offline mode. Some diagnostic functions stroke the valve over CAUTION part or full range.

  • Page 70: Continuous Diagnostics

    Among the aforementioned five types of the diagnostic tests, the standard valve diagnostic test strokes the valve over its full range and should not be run with the valve in service and the process running. The extended valve actuator signature, positioner signature and step profile tests allow the user to enter the starting point, end point, time duration or number of sampling of the test.

  • Page 79: Chapter 12: Failsafe Mode

    Chapter 12: Failsafe Mode SVI functions in normal operating, manual operating, configuration, calibration, diagnostic and fail-safe modes. Accordingly, ValVue has various windows to interface with these different modes. SVI does not go to failsafe mode if it functions normally. However, if a problem occurs the SVI will go to the safe mode, SVI will attempt to drive its output either to low signal or high signal to I/P based on its configura- tion.

  • Page 80: Exiting Failsafe Mode

    Among the list of problems, which may cause SVI to enter the FAIL SAFE MODE, inappropriate installa- tion or configuration, loss of air supply or insufficient air supply can cause the position error and position sensor error conditions. Other problems are more likely related to SVI hardware or software. Timeout of hardware watchdog timer clamps output to fail-save condition and initiates CPU reset.

  • Page 81: Chapter 13: Svi Message Responses

    Chapter 13: SVI Message Responses ValVue communicates with field device SVI through HART commands or message. These HART com- mands are available to access in the Normal Operating Mode window, Manual Mode window and FAIL SAFE MODE window. In each of these windows, ValVue provides a drop-down list of HART commands that you can select and send to the SVI, as illustrated in the Figure below.

  • Page 94: Chapter 15: Controller Configuration

    Chapter 15: Controller Configuration Chapter 9 of Configuration Mode describes the configuration of SVI as a positioner only. If the SVI Controller version is purchased and is enabled, the process controller is partly configured in configura- tion mode and partly in the Controller Parameters window, which is accessible from the Controller Monitor window (see Chapter 17 of Controller View).

  • Page 95: Controller Configuration In Controller Page

    Controller Configuration in Controller Page The Controller page is displayed by clicking the Controller Tab in the SVI Configuration window. A typi- cal Controller page is shown below (figure 54). This page allows the user to choose and set startup mode, initial setpoint, controller period, PV and SP units, and controller action.
  • Page 96 • Initial Setpoint: This parameter determines the initial local setpoint value if the startup mode is local, and the local setpoint when controller is switched from remote to local when the startup mode is remote and setpoint tracking is not selected. An appropriate value based on the specific application should be entered.

  • Page 97: Chapter 16: Controller Calibration

    Chapter 16: Controller Calibration Chapter 10 of Calibration Mode describes the calibration for SVI as a positioner only. If the built-in process controller option is purchased and enabled, the process controller is also calibrated in calibra- tion mode. This chapter deals with controller related calibration in calibration mode. Since some calibrate functions stroke the valve CAUTION over its full range, the valve should be isolated from...

  • Page 98: Range Page

    Range Page The Range page is the page displayed when entering the calibration mode. The Range page allows the user to enter the low and high range values for the primary and secondary input signals as well as cor- responding remote setpoint and process variable. •...

  • Page 99: Signal Calibration Page

    Signal Calibration Page When the built-in process controller is enabled, input from a separate process signal is measured and controlled by the built-in PID process controller. The calibration procedure for secondary analog signal is similar to that for primary analog signal. The Signal Calibration page (figure 56) appears when clicking the Signal Cal.
  • Page 100 Clicking the Secondary Signal button starts the calibration procedure for the secondary input signal sen- sor. The procedure will ask the user to: 1. Enter a low value for the measurement (e.g. 4.00 mA). 2. Set the input to that value. 3.

  • Page 101: Chapter 17: Controller View

    Chapter 17: Controller View SVI has a built-in PID process controller, which can be enabled in configuration mode if the controller option is purchased. The process controller is integrated with the SVI smart positioner to give a fast response to process changes and disturbances, gain a tight control of process variable, and facilitate a high level of loop monitoring functions.

  • Page 102: Figure 57. Controller Monitor Window

    • Local Setpoint: This is set to a constant value, which is manually adjustable, and is not read from the input channel (and thus will not respond to signal changes from the DCS or other controller). In local setpoint mode, the setpoint can be changed by local pushbutton or using HART commands through ValVue.

  • Page 103: Alarm Status

    Alarm Status There is a Module Status box in the top right of Controller Monitor window. This box displays the status of the process variable alarms. The alarms may be absolute or deviation alarms and are configured in Controller Parameters window: •...

  • Page 104: Controller Fault Messages

    Controller Fault Messages Controller fault messages and fail save are the same as for the positioner version. Refer to Chapters 12 and 13 for details. Mode Transfer of Process Controller The interface of the Controller Monitor window (figure 58) provides three buttons for mode transfer of process controller.
  • Page 105 • Local Automatic to Manual Control: Click the M button to make this transfer. The red mode light moves to the M button. The controller output remains unchanged at the moment of the transfer. • Manual to Remote Automatic Control: Click the R button to make this transfer. The red mode light moves to the R button.

  • Page 106: Process Trends

    Process Trends Clicking the Process Trend button in Controller Monitor window displays the Trend Data window (figure 59), which records position and process variable and their setpoints for the last 90 seconds. The time range is fixed at 90 seconds and the default range for Y-axis is 0 to 100%. However, you can adjust the Y-axis range precisely by entering Y-axis limits into the boxes at the left-top window and pressing Tab (or click in another box in the window).

  • Page 107: Controller Parameters

    Controller Parameters Some parameters of the process controller can be displayed and modified in any controller mode. To access these parameters, click the Set Param. button in the Controller Monitor window. The controller parameters will be retrieved from SVI device and presented in the following Controller Parameters win- dow (figure 60).

  • Page 108: Controller Parameter Descriptions

    Controller Parameter Descriptions • Proportional Gain (%): Proportional gain P is the ratio of proportional action (part of controller output) to error. The error is the difference between the setpoint and process variable. If the proportional gain is 50%, i.e., 0.5, the corresponding proportional band is 200%. •...

    • Derivative Source: Determines whether derivative action is applied to a change in the process variable or to a change in the error (setpoint - process variable). • Alarm Type: Determines whether an alarm is of the type absolute or deviation from setpoint. •...

  • Page 110: Chapter 18: Multiplexer Setup And Operation

    Chapter 18: Multiplexer Setup and Operation Introduction ValVue can support multiple SVI devices using a MTL HART multiplexer that allows a user to monitor and operate several SVI devices from a single computer. The MTL 4840 HART maintenance system is one of the most widely used multiplexer for communicating with HART instruments.

  • Page 111: Figure 62. Select Device Window

    One option a user must select correctly is which communication serial port the computer uses for the HART communication channel. Once selected in the Options window, this selection overrides any selection on the command line that starts the program. If the Allow Multidrop box in HART Optional is checked, ValVue supports HART devices (including SVIs) with non-zero polling addresses and supports multiple SVIs on the same loop (for split range applica- tions).

  • Page 112: Multiplexer Setup

    Multiplexer Setup Click the Mux Setup button to setup the nodes used on the MTL multiplexer. The Device Address win- dow appears and prompts for the nodes to be configured. Type a number between 1 and 31 for the desired node, ex. 1 for node 1 and click OK. The Multiplexer Setup window (figure 63) appears. Setup includes the following options and parameters.

  • Page 113: Multiplexer Operation

    • Multiplexer Master Mode: The multiplexer can communicate with a Hart device in primary master mode or secondary master mode. For ValVue use, this mode does not matter. However, ValVue must use the same mode set in Options window as the multiplexer. For other applications that use the multiplexer or when other Hart masters will be used, a particular selection may be necessary.
