Tag shutoff or bypass valves toguard against a “turn-on” while work is in progress.Bleed air from actuator and check that valve is in itsunenergized position.It is now safe to disconnect and remove any valve mounted equipmentthat is being replaced.For the procedure to mount rotary and reciprocating valves, refer to theMounting Instructions contained in the valve’s Mounting Box kit.Installing the SVI II AP Remote Position Sensor An option that is available for the SVI II AP is the Remote Position Sensor. The Remote Position Sensor, is a remotely mounted position-sensing device, that is connected electrically to an SVI II AP valve positioner. It is used as position feedback in applications where direct mounting of an SVI II AP to a valve actuator is not practical due, typically but not limited to, extreme vibration, heat or radiation.The Remote Position Sensor is a potentiometer located in an enclosure which can be mounted on a valve or damper to indicate stem position when connected to a suitable receiver. There is a three wire connection provided on a screw terminal block to interconnect to the receiving device.The SVI II AP Remote Position Sensor is suitable for installation outdoors in an industrial environment. Mounting kits are provided topermit mounting on a variety of valves.Do not remove the instrument cover or connect to an electrical circuit ina Hazardous Area unless the power is disconnected.Comply with current national and local regulationsfor electrical installation work.Installation and Set Up Installing the SVI II AP Remote Position SensorComply with national and local explosiveatmosphere regulations.Before carrying out any work on the device, poweroff the instrument or make sure that the localeconditions for potentially explosive atmospherepermit the safe opening of the cover.Installation ProcedureFor the Remote Position Sensor installation procedure refer to themounting instructions provided with the Remote Position Sensor.1.Remove the cover from the Remote Position Sensorassembly by turning the cover in a counter-clockwise (fac-ing the cover) direction.2.Connect the Remote Position Sensor to the mountingbracket by inserting four M6 x 20 mm Socket Head CapScrews through the appropriate screws holes (accordingto the valve) on the Remote Position Sensor bracket andusing a 3⁄16 inch Hex Key with tee handle.3.Route the instrument cable from the SVI II AP to theRemote Position Sensor (see Figure 3 on page 6 forinstallation instructions).4.Thread the cable through the conduit at the bottom of theRemote Position Sensor.ing a blade screwdriver, loosen the screws on theterminal block and connect the black, brown and red wiresto the appropriate labelled connectors.6.Tighten the screws.7.Attach the feedback lever to the Remote Position Sensorshaft.

Refer to the valve or actuatorinstruction manual.Masoneilan Dresser SVI II AP Quick Start GuideWiring the SVI II AP In order for the SVI II AP to communicate the positioner data the SVI II AP must be physically connected to a HART communication. The procedure below outlines wiring the SVI II AP.Comply with current national and local regulationsfor electrical installation work.Comply with national and local explosiveatmosphere regulations.Before carrying out any work on the device, poweroff the instrument or make sure that the localeconditions for potentially explosive atmospherepermit the safe opening of the cover.Connecting to the Control LoopThe SVI II APpositioner MUST BE grounded according to localregulations. It is important to maintain correct polarity at all times,otherwise the positioner may not operate properly. The SVI II APshould be physically connected to the HART loop using a cablespecified by the HART Communication Foundation. A shielded cableis recommended.To connect the Control Loop to the SVI II AP:1.Connect one end of the cable to the control loop's4 - 20mA output2.Remove the threaded wiring covers on the positioner.3.Connect the other end of the cable to the SVI II AP. Thereare two threaded openings on the positioner. Use theopening with the red plastic insert.4.Maintain polarity + and - respectively.Wiring GuidelinesThis list contains eight guidelines for a successful implementation of DCcurrent signal, DC power, and HART communication to the SVI II AP:pliance voltage at the SVI II AP must be 9 volts at themaximum current of 20 mA.2.Signal to the SVI II AP must be a regulated current in therange 3.2 to 22 mA.3.Controller output circuit must be unaffected by the HARTtones which are in the frequency range between 1200 and2200 Hz.4.Frequency range of the HART tones must have a circuitimpedance of more than 220 Ohms, typically 250 Ohms.5.HART tones may be imposed by the positioner and acommunication device located anywhere on the signalingcircuit.Installation and Set Up Wiring the SVI II AP6.Capacitance of the signaling circuit must not exceed 0.26microfarads or 0.10 microfarads with high seriesresistance.7.Cabling must be shielded to prevent electrical noise thatwould interfere with the HART tones, with the shieldgrounded.8.Signal must be properly grounded in only one place.Note:For details and calculation methods for wiring resistance, andcapacitance and for calculation of cable characteristics pleaserefer to the HART FSK Physical Layer Specification.SVI II AP SetupsTypical system setups are shown in Figure 6 on page 13, GeneralPurpose and Explosion Proof (EEx d) Installation Schematic and Figure7 on page 13, Intrinsically Safe Installation Schematic. The SVI II APpositioner can be located in a general-purpose or hazardous areaprotected by Explosion Proof (EEx d) methods. Wiring diagrams aregeneralized, actual wiring must adhere to Electrical Installation sectionof manual and local electrical codes. The use of a HandheldCommunicator or a HART modem is not permitted in the HazardousArea protected by Explosion Proof (EEx d) methods. In Figure 7 onpage 13 the SVI II AP positioner is located in a hazardous area that isprotected by Intrinsically Safe wiring practices.The SVI II AP requires an electrical input from a 4-20 mA currentsource. The SVI II AP input signal can carry a HART communicationprotocol signal from ValVue 2.4 or greater software and a HARTmodem, or from a HART Hand Held Communicator. Since the processcontrol system, the source of the input signal, is located in a non-hazardous location, setup requires an intrinsic safety barrier be placedbetween the process control system and the SVI II AP. If the SVI II APis located in a hazardous area with Intrinsically Safe protection a barrieris not required for a flameproof installation. Alternatively the systemcan be installed as Explosion Proof ⁄ flameproof. SVI II AP cancommunicate with a remote PC running ValVue software via a modemconnected to the PC's serial or USB port. The PC, which is notintrinsically safe, must be connected to the circuit on the safe area sideof the intrinsic safety barrier if the valve is located in a hazardous area.The SVI II AP can be operated, calibrated, configured, and interrogatedeither by using local pushbutton and display, or by using a PC runningValVue 2.4 software, HART Handheld Communicator, or any registeredHART Host that supports DDs. The HART Handheld Communicator isapproved for Intrinsically Safe use in accordance with FM and ATEXstandards. Read and observe all HHC labelling. The SVI II AP ispolarity sensitive so the positive lead must be connected to the positive(+) terminal and the negative lead to the negative (-) terminal. Reversalof input will not cause damage but the unit will not function.。
