ValVue ESD searches through all connected devices.
PAGE 60
Using a Device List File The device list can be saved in a file to eliminate rescanning each time Connect is selected. This is useful only with multiplexors. Unless Load Device List from Database on Startup is selected as an option, the device addresses file used is temporary and is rescanned each time the program is restarted. If selected, you can select a file to save the device list. This file is read when the program is started and the list displayed.
PAGE 61
Mux Option The Use Multiplexor option allows you to select multiplexor operation. If the Use Multiplexor control is checked then the MUX Setup, and MUX reset controls are added to the Connected Devices page context (right click) menu. Check Use Multiplexor and set a baud rate that is equal to the baud rate set on the multiplexor hardware with DIP switches. NOTE Settings in the Options page for ValVue ESD must agree with the MUX configuration settings that are also shown.
PAGE 62
Multiplexor Setup and Operation ValVue ESD supports the MTL HART multiplexor allows you to monitor and operate many SVI II ESD PST controllers from a single computer. The MTL 4840 HART maintenance system is a widely used multiplexor for communicating with HART instruments. Connected to a computer serial port with an RS232/RS485 converter, the multiplexor is capable of supporting up to 31 nodes, each with the capability of supporting up to 16 sub nodes. Each sub node can control 16 loops.
PAGE 64
Configuring the Multiplexor 1. Select MUX Setup from the context menu to setup the nodes used on the MTL multiplexor. The Connected Devices page appears and prompts for the nodes to be configured. 2. Type a number between 1 and 31 for the desired node, e.g. 1 for node 1 and select OK. The node address must match the DIP switch setting on the MUX hardware. The Multiplexor Setup dialog appears (Figure 59). 3. Set the Master Mode: Primary or Secondary Master.
PAGE 65
Preamble Count A device using the HART protocol sends a short string of characters at the beginning of each communication to wake up the other device. This string is called a preamble. The number of preambles prefixed to each Hart command sent to a device varies from device to device. The valid range is 2 to 20. Recommended values for this parameter are 3 to 5 when using the Mux. ValVue ESD allows for a user-configured Mux preamble count.
PAGE 66
NOTE The Mux hardware re-scan is different from the re-scan performed by ValVue ESD from the Re-scan button. No communication between ValVue ESD and any device takes place on the node until the reset is completed. This can take several minutes, depending on MUX loading. Scan Option The MTL multiplexor has the capability to continually scan the connected Hart devices to report the results.
PAGE 67
Troubleshooting ValVue ESD Used with Mux Table 3 lists some of the problems, causes, and corrective actions you may encounter when setting up ValVue ESD used with a multiplexor (Mux). Table 3 Troubleshooting ValVue ESD Used with Mux Problem Cause Corrective Action Both ValVue ESD and AMS are connected to the Mux Connect ValVue ESD to the device with a modem. If the installation is fundamentally safe connect the input to the MTL 4046P Isolator.
PAGE 68
Configuring Burst Mode The Burst Mode is a mode where the HART device continuously sends out data without being polled for such data, by a Master. This mode is useful only for devices that are passive (i.e. not a HART master), such as a HART to Analog converter (SPA from Moore Industries, Tri-Loop by Rosemount). It is not necessary to set the burst mode to allow communications with a control system since the control system is a master capable of polling the device.
PAGE 69
Launching a Device ValVue ESD opens the Connected Devices connection window (Figure 60), searches for connected devices and lists those devices. To stop the searching process, select Stop. The list includes offline device files and live devices. Scanning can take a few seconds if multidrop is selected. When a Multiplexor is used, the process can take a longer time, depending upon how many devices are connected. The Connected Devices window is the interface tool for ValVue ESD and devices operating ESDVue.
PAGE 70
Offline Mode There is on offline mode available in ValVue ESD to work with a disconnected Masoneilan HART devices. The offline options serve two purposes: Viewing configuration, calibration and diagnostic data, for SVI II ESD using a dump file (.dp3). Learning the features and functions of both SVI II ESD and ValVue ESD when they are not connected to an actual device.
PAGE 71

PST Controller Characteristics The PST controller Characteristics displayed on the Monitor screen consist of: Signal (mA) - Indicates the input analog signal expressed in mA. Position (%) - Indicates the actual valve position in % of valve opening. 0% is always closed and 100% is open. Pressure (pressure units) - The SVI II ESD continuously monitors the actuator pressure. It is displayed according to the configured units (psi, bar, or kpa). I/P Current - the current in mA generated by the I/P.
PAGE 95
Position Indicates the actual valve position in % of valve opening. 0% is always closed and 100% is open. Because the travel of a valve may exceed its nominal travel, positions greater than 100% are possible. Setpoint In NORMAL mode, the setpoint is the target position based on the characterized input. In MANUAL mode, it is the target position to which the SVI II ESD is controlling the valve. Change the manual setpoint by dragging the lower thumb on the position indicator. © 2014 General Electric Company.
PAGE 96

Several level of locks are provided: Allow Local Buttons (level 3): Buttons on the SVI II ESD are enabled. Lock Out Local Cal. - Config.
PAGE 126
Position Error Time Use this to define the amount of time a position error is allowed to exist before the valve is put in failsafe position. The Position Error Time must be between 1 and 328 seconds. If you set a value for Position Error Time outside the range an error message appears (Figure 102). Figure 102 Position Error Time Error Message Valve Stuck Limit The SVI II ESD issues an alert if a valve is stuck.
PAGE 127
Near Closed Use this to determine the value of position below which the valve is considered near closed by the continuous diagnostic calculations. The Near Closed value is defined as a percentage of the total partial stroke. The Near Closed value must be between 0% and 20%. If you set a value for Near Closed outside the range an error message appears (Figure 105). Figure 105 Supply Limit Low Use this to define the supply pressure value that when sensed by the SVI II ESD is considered too low.
PAGE 128
PST Allow Options The PST Allow options provide the following configuration options: Allow PST by HART - When enabled, PST is executed by HART command from a HART device. Allow PST by Button - When enabled, PST is executed by the display button. Allow PST by AI - When enabled, PST is executed by Analog Input. Latch Trips Enabled - When disabled, the SVI II ESD takes no action when the SVI II ESD is tripped. You can enable this checkbox to enable latch trips.
PAGE 129
Pressure Units You can select the units in which the actuator pressure is reported: psi, bar, or kpa. Air Action Use this option to set the action of air on the valve; Air To Open causes air to open the valve and Air To Close causes air to close the valve. Configure I/O Use this to define characteristics of the inputs and output switches and position retransmit. Accessing Configure I/O Click Configure I/O on the Configure screen and ESDVue launches the I/O Configure window (Figure 108).
PAGE 130
Output Switches (DO2) The SVI II ESD supports two identical contact outputs which can be logically linked to status bits. The two output switches can be opened or closed in response to conditions that the SVI II ESD detects (only one switch is configurable for the ESD). The switches are polarity sensitive and must be connected only to a DC circuit. The switch (+) terminal must be electrically positive with respect to the ( –) terminal.
PAGE 131
If both Position High Limit and Full Open Above are used, the Position High Limit must be below the Full Open Above. CAUTION 7. Manual Mode The switch is activated whenever the SVI II ESD is in manual mode, configure mode, calibrate mode, or diagnostic mode. 8. Annunciate The switch is activated whenever the SVI II ESD makes an annunciation; e.g. diagnostics are running, SVI II ESD status has changed. 9. ESD Triggered The switch is activated whenever an Emergency Shutdown event is triggered. 10.
PAGE 132
The maximum voltage that can be applied to the digital switch outputs is 30 VDC. This is an open circuit parameter (the digital switch is in the open state). Under open circuit conditions, the switch current will be less than 0.200 mA. The switch maximum current rating is 1 A. When the switch is ON, the typical switch voltage is V. It is essential that the external circuit controls voltage such that the switch saturation voltage is maintained.

Step 3 - Calibrate Travel To determine valve position, the PST controller must measure the closed and open positions of the valve. The SVI II ESD first exhausts the actuator and measures the position, then fills the actuator and measures the position. From these measurements the valve position is determined. To calibrate PST controller travel: Click the Calibrate Travel checkbox (Figure 117). Figure 117 NOTE © 2014 General Electric Company. All rights reserved.
PAGE 140
Step 4 - Autotune The SVI II ESD has a built-in positioning Autotune feature. When setting up the PST controller on a valve, this feature automatically computes the optimal parameters for the positioning algorithm. This features does not require valve specific parameters in order to complete successfully. The patented algorithm analyzes the dynamic behavior of the valve assembly, and determines values for the tuning algorithm that are optimal for tight and accurate position control.

Calibrate Context Menu When you right-click on the Calibrate screen, a context menu appears (Figure 165). Most functions available in the Calibrate context menu are used for advanced SVI II ESD setup and are only accessible when ESDVue is in the setup mode. Refer to “Advanced Setup with ESDVue” on page 335 for further instructions. NOTE Figure 165 Calibrate Screen Context Menu The following items are on the Calibrate context menu. Run Find Stops - runs the automatic position calibration process.
PAGE 176
Full Open - Moves the valve to full open. This command works by taking the valve out of closed loop control and sends a high or low signal to the I/P. Full Closed - Moves the valve to full closed. This command works by taking the valve out of closed loop control and sends a high or low signal to the I/P. Set Valve Position - Allows you to set the valve to a specific position (this is accomplished by momentarily returning to manual mode, repositioning the valve, and returning to setup mode).
PAGE 177
Run Find Stops To determine valve position, the PST controller must measure and save the closed and open positions of the valve. This can be done automatically by running the Run Find Stops procedure from the Calibrate screen context menu. The SVI II ESD first exhausts the actuator and measures the position, then fills the actuator and measures the position. From these measurements the valve position is determined. Correction can be made for nominal valve travel if it is less than full travel.

Manual Find Stops On some actuators it is possible that the automatic Find Stops procedure will not find the correct end positions of the travel. A semi-automatic method of calibrating the stop positions is provided. When Manual Find Stops is selected, the valve is moved to full closed and you are asked to respond when the valve has reached the full closed position. The valve is then moved to full open and you are asked to respond when the valve has reached the full open position.

PST Configuration Use this to configure PST, or partial stroke testing, operation. Partial Stroke Test Settings The configurable PST parameters are as follows (Figure 252): Figure 252 PST Settings PST Travel - The allowed valve movement from full Open position in percentage of travel. A typical value is 20%. Maximum allowed is 30%. The greater the travel range, the more accurate the results from the PST test.
PAGE 243
Maximum Time – The allowed amount of time in seconds before the PST test aborts. This value can be determine as follows: Maximum Time = (Travel Range * 2 * PST Speed) + Dwell Time +5 seconds. PST Speed - The valve travel speed in % Travel per second. Dwell Time - The amount of time in seconds between the down ramp and the up ramp of valve stroke. Friction Low Limit - The alarm threshold for low friction. This alarm is set if the analyzed friction from the PST test is less than this value.
PAGE 244
Minimum Pressure When configuring the Minimum Pressure for the PST you are configuring the minimum amount of pressure required for the Partial Stroke Test. The pressure change value is in the configured pressure units. The PST Pressure Change must be between -120.0 and 120.0 psi (-828 and 828 kPa, -8.28 and 8.28 bar). If you set a value outside the range an error message appears (Figure 254).
PAGE 245
Dwell Time The Dwell Time is the amount of time in seconds between ramp down and ramp up of valve stroke; similar to a threshold state. When performing a PST you want the dwell time range to be between 2 and 60 seconds. If you configure the Dwell Time parameter outside this range an error message appears (Figure 257). Figure 257 Dwell Time Error Message Friction Low Limit Friction Low Limit is the minimum amount of pressure provided during the PST to overcome valve packing friction.
PAGE 246
Breakout Limit The Breakout Limit is the maximum amount of pressure applied to cause valve to break loose and move. Configure this parameter in pressure units in a range between 0.0 to 30.0 psi (0.0 to 207 kPa, 0.000 to 2.069 bar). If you configure a value outside the specified range an error message appears (Figure 260). Figure 260 Breakout Limit Error Message Droop Limit The Droop Limit is the amount of pressure drop allowed between ramp down and ramp up of valve stroke in pressure units.

Check What you can do on the Check Screen Check screen provides a method for monitoring and adjusting some of the basic parameters. This screen is used primarily for troubleshooting. You can: Send a HART command and view the result. Use the Check screen right click menu or the Tools menu to set the SVI II ESD to Full Open, Full Closed and Detach Trend.To perform any action from the Check screen Context Menu, ESDVue must be in the Setup mode. (See “Change Mode” on page 83 for further information.
PAGE 328
Information Displayed on the Check Screen The Check screen is used for troubleshooting and displays the operating parameters of the SVI II ESD including: Position Indicates the actual valve position in % of valve opening. 0% is always closed and 100% is open. Because the travel of a valve may exceed its nominal travel, positions greater than 100% are possible. Lower Stop The Lower and Upper Stop values are the A/D values measured from the position sensor at the full travel of the valve.
PAGE 329
Supply Pressure This is the pressure generated by the air supply. Raw Supply Pressure The A/D value measured from the air supply. This is used for troubleshooting purposes. Pilot Pressure Pilot Pres (pressure units) is pressure generated by the I/P. Raw Pilot Pressure The A/D value measured from the I/P pressure sensor. This is used for troubleshooting purposes.

Figure 326 Send Command Results Displayed List of Available HART Commands The following commands can be sent to the SVI II ESD: 000 Read Identifier - returns the unique identifier from the device including the device ID, device type, and the manufacturers ID. 001 Read Primary Variable - returns the position in percent open. 002 Read Current - returns the input signal in mA.
PAGE 332
016 Read Assembly Number - reads the final assembly number that was stored in the device when it was assembled at the factory. 017 Write Message - enter a message (up to 32 characters) for storage in the SVI II ESD. 018 Write Tag & Descriptor - enter a tag name (up to 8 characters) and a description (up to 16 characters) that are stored in the SVI II ESD. 019 Write Final Assembly - enter an identifying number (0 to 16 million) that is stored in the SVI II ESD.
PAGE 333
Full Open - Moves the valve to full open. This command works by taking the valve out of closed loop control and sends a high or low signal to the I/P. Full Closed - Moves the valve to full closed. This command works by taking the valve out of closed loop control and sends a high or low signal to the I/P. Detach Trend - Removes the trend display from the tabbed dialog and creates a separate trend display. Help - Displays the on-line help at the Check screen instructions.

Advanced Setup with ESDVue Overview This section provides instructions for a custom, or advanced setup of the SVI II ESD with ESDVue. Methods to Set Up the SVI II ESD There are two methods of setting up the SVI II ESD with ESDVue: Run Setup Wizard from the Configure screen. Advanced Setup of the SVI II ESD by an advanced user The Setup Wizard automatically runs through the specified setup routines and is the recommended method for initializing an SVI II ESD.
PAGE 336
Configuration Parameters Refer to “What You Can Do on the Configure Screen” on page 123 for configuration instructions. Calibration Steps The calibration steps in an advanced setup are: Run Find Stops or 1. Run Manual Find Stops. 2. Run Auto Tune. 3. View calibration parameters. Run Find Stops To determine valve position, the PST controller must measure and save the closed and open positions of the valve. Do this automatically by running the Run Find Stops procedure.

Manual Find Stops On some actuators, it is possible that the automatic Find Stops procedure will not find the correct end positions of the travel. A semi-automatic method of calibrating the stop positions is provided. When Manual Find Stops is selected, the valve is moved to full closed and you are asked to respond when the valve has reached the closed position. The valve is then moved to full open and you are asked to respond when the valve has reached the full open position. To run Manual Find Stops: 1.
