During normal operation, these ESD valves are typically energized to stay open (ATO). In case of an unsafe situation, the ESD valve is de-energized by the Safety System. The SVI II ESD device performs this shutdown function for Safety Instrumented Functions (SIF) that require field devices to be certified for safety related applications according to IEC61508 as certified by TUV for use up to SIL3 with an HFT of 0 in low demand applications.
The SVI II ESD is intended to be part of final element subsystem, as per IEC 61508, and the achieved SIL level of the function must be verified by the function designer.
The SVI II ESD’s safety critical function is maintained by a Type A Device. Therefore based upon the SFF > 90%, when the SVI II ESD is used as the sole component in a final element subassembly, a design can meet SIL 3 @ HFT=0.
Maintenance Refer to “SVI II ESD Maintenance” on page 137. Diagnostics The SVI II ESD provides several types of diagnostic information: Continuous device diagnostics Internal diagnostics that run every hour and require no user configuration Partial Stroke Testing (PST) diagnostics You can configure and run PST at any time.
Inspect the SVI II ESD for dirty or clogged ports and other physical damage De-energize the SVI II ESD and observe that the actuator and valve move. Energize the SVI II ESD after the valve has moved to its full stroke length. An accumulated value of 100% travel = 1 stroke. The travel does not need to occur in one movement.
SVI II ESD Product Safety The SVI II ESD is intended for use with industrial compressed air or sweet natural gas systems only. Ensure that an adequate pressure relief provision is installed when the application of system supply pressure may cause peripheral equipment malfunctioning. Installation must be in accordance with local and national compressed air and instrumentation codes.

4. Installation and Setup Overview Figure 40 shows the SVI II ESD positioner which is designed to prevent and mitigate possibly negative situations. It is a position controller assembled on a pneumatically actuated valve assembly. Its role is to position an emergency shutdown valve to 0% or 100% with a probability of failure on demand (PFD) in accordance with IEC61508 for SIL3 application.
Pre-Installation Issues Storage If the SVI II ESD is stored for a long period of time, you must keep the housing sealed against weather, fluids, particles, and insects. To prevent damage to the SVI II ESD: Use the plugs provided with shipment to plug the ¼ NPT air connections, on the positioner and on the air filter regulator set.
Keep the Breather/Vent port accessible and for inspection for obstruction during manual proof testing. Mount the SVI II ESD in a mild vibration environment. If excessive vibration can be expected, take special precautions to ensure the integrity of electrical and pneumatic connectors or reduce the vibration using appropriate damping mounts.

The most basic and easiest interface is the local pushbutton and display option mounted on the SVI II ESD. It is available at any time and provides immediate local access to most configuration, parameters, calibration procedure, and fault messages. It is approved for use in Explosion Proof and Intrinsically Safe installations in Hazardous Areas.
Hazardous Areas in accordance with SVI II ESD Approvals. ValVue ESD ValVue ESD combines the power of the PC with the features of SVI II ESD for ease of use and automation of positioner operation giving full access to all data. ValVue ESD is provided with all SVI II ESD positioners and is recommended for set up, service and maintenance where a PC or laptop is permitted.
Using pushbuttons you can change operating modes at any time and step through a menu structure to perform manual operation, calibration, configuration, and monitoring functions. SVI II ESD provides internal diagnostics and if a fault is detected it appears on the display. ValVue ESD provides advanced diagnostic functions. The pushbuttons do not support ValVue ESD advanced diagnostics functions.
Using CONFIG (configuration) menu you can set the following parameters: ATO/ATC, Pressure units, display language. CALIB Using CALIB (calibration) menu you can calibrate SVI II ESD by running STOPS (find stops) and TUNE (autotune) functions. PST CONF Using PST CONF (PST configuration) menu you can configure the following PST parameters:...
See ValVue ESD On Line Help for more details. The SVI II ESD offers several security levels. It may be desirable, after initial setup, to lock the pushbuttons so that the SVI II ESD parameters cannot be inadvertently changed by buttons.
Page 106
Additional security is achieved by using the hardware configuration-lock jumper shown in Figure 26 on page 43 through Figure 28 on page 44 (based upon SVI II ESD model). When set to secure position, shorting the two-pin header, configuration and calibration are not permitted using local interface or by remote communications.
NORMAL mode. When in the MANUAL mode the device does not ® respond to the 4 - 20 mA signal. However, the SVI II ESD unit can still respond to HART ® commands, including HART commands to position the valve.

To ensure integrity of the ESD valve, SVI II ESD requires periodic testing. One of the great features of the SVI II ESD is the ability to test the safety valve on-line, without removing it from the SIS. SVI II ESD allows you to automatically, or on demand, perform a Partial Stroke Test (PST) which returns relevant data concerning valve operation and can allow you to detect potentially dangerous failures.
Partial Stroke Test Diagnostics The SVI II ESD is capable of partially stroking the valve to detect failures in the final control element assembly. PST is configured using the pushbutton display or through ValVue ESD. The PST can be configured to automatically start or be initiated by setting current input to 16.4 mA, local control panel pushbutton, or field initiated by an operator.
PST Setup with ValVue ESD When configuring PST with ValVue ESD, more parameters are available. You can configure dwell time, friction low and high limits, breakout limit, droop limit and can freeze DO and AO switches. ValVue ESD also provides the ability to schedule PST, so that PST automatically runs at the scheduled time.
8. Operation and Maintenance Operational Overview SVI II ESD is Masoneilan’s solution to improve safety in a processing plant; it is designed to prevent and mitigate possibly uncontrollable situations. SVI II ESD is a SIL 3 compliant Smart Valve Interface that continuously monitors the ESD valve operation of the and reports any operational failures.
SVI II ESD Applications and Designated Safety Function Activation There are three (3) SVI II ESD configurations used to connect to the control system in four (4) different scenarios. The three configurations are used exclusively and cannot be combined in any way.
The SVI II ESD acquires actuator pressures, valve position, air supply, and set-point whether the safety function is invoked or not. The SVI II ESD captures and stores data when the safety function is invoked. The result is an automatically saved as a signature in the non-volatile memory.
Physical and Operational Description SVI II ESD is a smart electro-pneumatic positioner that receives a 4 - 20 mA electrical position setpoint signal from controller and compares it with valve position feedback sensor. The difference between position setpoint and position feedback is analyzed by position control algorithm that sets a servo signal to I/P converter.
A/D, D/A, temperature sensor, Hall-Effect magnetic position sensor, pressure sensors, micro controller, and a power management/distribution circuit. The programs controlling SVI II ESD positioner are stored in a flash memory allowing download of upgraded firmware. A separate non-volatile memory stores configuration information, and continuous diagnostic results.
Output Switches Introduction The SVI II ESD supports two identical contact outputs, SW #1 and SW #2 (Digital Output switches), that can be logically linked to status bits. The Digital Output switch terminals are solid state contacts. Each switch requires its own power source and must be connected to the appropriate connector on the Electronics Module Terminal Board.
Load is designed to ensure that voltage across the switch is < 1 V. LOAD If the load is inductive (solenoid, incandescent lamp, etc.), then install a Freewheel or Flyback di- ode to prevent switch damaging EMF voltage SVI II ESD spikes. Switch Output: External 1 V with...
Page 135
The two digital 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). These conditions are: Always Normal Position - the switch is not controlled by the SVI II ESD and remains in it’s default position. The two digital output switches can be opened or closed in response to detected conditions.
Position Transmitter (AO) The SVI II ESD has the ability to retransmit the position signal as an output to another device with 4 - 20 mA current output proportional to position. Enter a lower range value and an upper range value.
A conservative approach is taken in estimating the service interval for the digital valve controller in Safety Instrumented Systems. For SIS applications, preventive maintenance should be performed on the SVI II ESD five years from date of shipment if the average daily ambient temperature is below 60° C (140° F). For applications where ambient temperature exceeds 60°...

The replacement display cover is shipped with a lanyard to prevent the cable (that connects from the display to the Terminal Board) from breaking. The lanyard must be inserted under the screw in the lower left corner, that attaches the terminal board to the SVI II ESD housing. To Install the cover: 1.
SVI II ESD is equipped with a nonvolatile re-writable Flash Memory for program storage. The firmware can be updated as improvements and advances are made in the embedded programs that operate the SVI II ESD. Firmware improvements for SVI II ESD can be obtained by contacting the factory.
9. Troubleshooting Overview One of the key features of SVI II ESD is the ability to diagnose and announce any SIS failure. This section provides information describing the SVI II ESD diagnostics and how to use the diagnostic information to troubleshoot the cause of the problem.
Several of the internal diagnostics tests put the SVI II ESD into FAILSAFE mode if the errors continue for a preset time. When SVI II ESD goes into FAILSAFE, the valve is driven to its Failsafe position. It remains in that position until the cause of the error is cleared and the instrument is reset.
VIEW ERR Diagnostics Messages Diagnostic messages are viewed with VIEW ERR from the MANUAL mode menu or from NORMAL mode menu. VIEW ERR menu item allows you to read current status information. To clear error messages: Press * at CLR ERR on either MANUAL or NORMAL mode menus. Exiting from the VIEW ERR menu returns to the previous menu.

Compliance Voltage in Single Drop Current Mode SVI II ESD requires 9.0 V at 20 mA and 11.0 V at 4 mA. Typical smart devices require MORE Voltage at higher current. The controller supplying the current has LESS voltage available at higher current.
Figure 26 on page 43 through Figure 28 on page 44 (based upon SVI II ESD model). Terminals accept wire sizes up to AWG 14. The SVI II ESD is supplied with two 1/2” NPT conduit entries. M20 adapters are available. Internal and external ground terminals are provided for use if grounding is required.
® HART Physical Layer Compliance of the Control System ® Communicating with an SVI II ESD requires a HART -compliant communications loop. The ® HART protocol specifies the noise level, impedance requirements, and configuration of the loop.

ESD requires special consideration of the compliance voltage. The SVI II ESD requires at least 9.0 V. Two SVI II ESD in series requires at least 18.0 V in addition to the voltage drops in wiring and other series devices. Typical controller output current sources rarely deliver 24 V, so the system can become voltage starved.
® ValVue ESD supports HART devices including, the SVI II ESD with non-zero polling addresses and multiple SVI II ESDs on the same loop, for split ranging purposes. To enable split ranging support through ValVue ESD the Multidrop function must be activated.

An alternative approach is to boost DCS compliance voltage using a supplemental power supply (see Figure 88 on page 191) with split ranged SVI II ESD positioners connected in series with the supply. It is not recommended to use supplemental supplies when Intrinsic Safety is required.
Required Practices for Explosion Proof Installations The SVI II ESD is supplied with two threaded conduit entries. All wiring must be installed with approved conduit and seals or with approved cable and cable glands according to local codes. The spare conduit entry is plugged with a ½" NPT pipe plug. Thread engagement must comply with local electrical codes.
Safety Overview When an SVI II ESD is installed in a hazardous area suitable wiring arrangements in addition to safety requirements must be used, in accordance with local applicable codes and standards for Intrinsic Safety. For choice and application of intrinsic safety barriers special training is required.

Output Channel Isolation The designer of the signaling circuit where the SVI II ESD has to be installed must consider the eight design rules in Wiring Guidelines (see “HART® Wiring Guidelines” on page 177). In particular, the control system output interface has galvanically isolated analog output channels and share a common ground or are separated from ground by a current control transistor or sense resistor.

Read the product Manual for the HART Communicator. Observe all warnings. The intrinsic safety entity parameters must be added to the SVI II ESD entity parameters to determine suitability for use in any intrinsically safe circuit. Observe the labels on the DPI 620 or consult the manufacturer.
Even the control valve subsystem can be complex. Figure 92 and Figure 93 show air to open action, ATO, and air to close, ATC, valves used with SVI II ESD. The figures show a direct acting positioner with linear and percentage characteristics. Some hysteresis is shown for actuator pressure signal caused by friction in typical actuators.
This includes failure of the air supply. SVI II ESD is designed to fail to a condition of low or no air pressure. Choose control valve actuators to move the valve to a safe condition when air pressure is low or absent. For example, a valve supplying fuel to a combustion process is normally equipped with an Air to Open valve.
The auto tune feature has robust tuning parameters designed to tolerate variations in process characteristics. You can adjust control valve speed of response by adjusting parameters in SVI II ESD. Tuning parameters are adjusted by ValVue ESD, the preferred method, or by the handheld.
An algorithm is a procedure or formula for solving a problem. There are several algorithms entailed in SVI II ESD operation. SVI II ESD has a position control algo- rithm that is a modified PID algorithm. Other embedded algorithms in SVI II ESD include STOPS method for calibrating stroke, and autoTUNE method for estab- lishing the best parameters for the PID algorithm.

Positioner Tuning Parame- The positioner requires six integer parameters to determine its ters response for a setpoint change. Internally, the positioner uses an improved PID control algorithm to control valve position. Tuning Parameters P is a dimensionless gain factor related to proportioning action of the algorithm.

This discussion explains how to determine compliance voltage for an SVI positioner. It applies to the SVI II AP, SVI II ESD, SVI II APN and SVi1000. A definition of compliance voltage is: The voltage that must be available at the control system output in order to drive the control current through the SVI II AP and all the resistive devices in series with it.
