Necessary Precautions To avoid injury or the process being affected when installing or replacing a positioner on a control con trol valve, ensure that:
If the valve is located in a hazardous area make sure the area has been certified as “safe” or that all electrical power to the area has been disconnected before removing any covers or disconnecting any leads. Shut off air supply to the actuator and to any valve mounted equipment. Ensure the valve is isolated from the process by either shutting off the process or using bypass valves for isolation. Tag Tag shutoff or bypass valves to guard against a “turn-on” while work is in progress. Bleed air from actuator and check that valve is in its unenergized position. It is now safe to disconnect and remove any valve mounted equipment that is being replaced. For the procedure to mount rotary and reciprocating valves, refer to the Mounting 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. Sensor. The Remote Position Sensor, Sensor, is a remotely mounted mounted positionsensing device, that is connected electrically to an SVI II AP valve positioner. positioner. It is used as position feedback in applications where direct 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 suitable receiver. receiver. There is a three wire connection 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. environment. Mounting kits kits are provided to permit mounting on a variety of valves.
Do not remove the instrument cover or connect to an electrical circuit in a Hazardous Area unless the power is disconnected.

Wiring the SVI II AP
SVI II AP Quick Start Guide
In order for the SVI II AP to communicate the positioner data the SVI II AP must be physically connected to a HART HART communication. The procedure below outlines wiring the SVI II AP.
Comply with current national and local regulations for electrical installation work. Comply with national and local explosive atmosphere regulations. Before carrying out any work on the device, power off the instrument or make sure that the locale conditions for potentially explosive atmosphere permit the safe opening of the cover.
Connecting to the Control Loop The SVI positioner MUST BE grounded according to local regulations. It is important to maintain correct polarity at all times, otherwise the positioner may not operate properly. properly. The SVI II AP should be physically connected to the HART loop using a cable specified by the HART Communication Foundation. Foundation. A shielded cable is recommended. recommended. To connect the Control Loop to the SVI II AP:
1. 2. 3. 4.
Connect one end of the cable to the control loop's 4 - 20mA output Remove the threaded wiring covers on the positioner. positioner. Connect the other end of the cable to the SVI II AP. There are two threaded openings on the positioner. Use the opening with the red plastic insert. Maintain polarity + and - respectively.
Wiring Guidelines This list contains eight guidelines for a successful implementation implementation of DC current signal, DC power, and HART communication to the SVI II AP:
1. 2. 3. 4. 5.
Compliance voltage at the SVI II AP must be 9 volts at the maximum current of 20 mA. Signal to the SVI II AP must be a regulated current in the range 3.2 to 22 mA. Controller output circuit must be unaffected by the HART tones which are in the frequency range between 1200 and 2200 Hz. Frequency range of the HART tones must have a circuit impedance of more than 220 Ohms, typically 250 Ohms. HART tones may be imposed by the positioner and a communication device located anywhere on the signaling circuit.

Installation and Set Up
Wiring the SVI II AP
6. 7. 8.
Capacitance of the signaling circuit must not exceed 0.26 microfarads or 0.10 microfarads with high series resistance. Cabling must be shielded to prevent electrical noise that would interfere with the HART tones, with the shield grounded. Signal must be properly grounded in only one place.
Note: For details and calculation methods for wiring resistance, and capacitance and for calculation of cable characteristics please refer to the HART FSK Physical Layer Specification.
SVI II AP Setups Typical system setups are shown in Figure 6 on page 13, 13 , General Purpose and Explosion Proof (EEx d) Installation Schematic and Figure 7 on page 13, 13, Intrinsically Safe Safe Installation Schematic. The SVI II II AP positioner can be located in a general-purpose or hazardous area protected by Explosion Proof (EEx d) methods. Wiring diagrams are generalized, actual wiring must adhere to Electrical Installation section of manual and local electrical codes. The use of a Handheld Communicator or a HART modem is not permitted in the Hazardous Area protected by Explosion Proof (EEx d) methods. In Figure 7 on page 13 the SVI II AP positioner is located in a hazardous area that is protected by Intrinsically Safe wiring practices. The SVI II AP requires an electrical input from a 4-20 mA current source. The SVI II AP input signal can carry a HART communication protocol signal from ValVue ValVue 2.4 or greater software and a HART modem, or from a HART HART Hand Held Communicator. Communicator. Since the process control system, the source of the input signal, is located in a nonhazardous location, setup requires an intrinsic safety barrier be placed between the process proc ess control system sys tem and the SVI II AP AP. If the SVI II AP is located in a hazardous area with Intrinsically Safe protection a barrier is not required for a flameproof installation. Alternatively the system can be installed as Explosion Proof ⁄ flameproof. SVI II AP can communicate with a remote PC running ValVue ValVue software via a modem connected to the PC's PC's serial or USB port. The PC, which is not intrinsically safe, must be connected to the circuit on the safe area side of the intrinsic safety barrier if the valve is located in a hazardous area. The SVI II AP can be operated, calibrated, configured, and interrogated either by using local pushbutton and display, or by using a PC running ValVue 2.4 software, HART Handheld Communicator, Communi cator, or any registered registe red HART Host that that supports DDs. The HART Handheld Communicator Communicator is approved for Intrinsically Safe use in accordance with FM and ATEX standards. Read and observe all HHC labelling. The SVI II AP is polarity sensitive so the positive lead must be connected to the positive (+) terminal and the negative lead to the negative (-) terminal. Reversal of input will not cause damage but the unit will not function.

Grounding Practices To ensure proper grounding make sure that case, signal, and ground connections are made in compliance with the plants normal grounding practices. Any point in the loop can be referenced to ground, but there there must never be more than one ground point. Normally ground is connected at the controller or at the intrinsic safety barrier. The case grounding screws are located on the outside of the case at the lower right of the the display cover and inside the cover. cover. The case is isolated from all circuitry and can be grounded locally in accordance with applicable codes. If noise or instability is present set the positioner to MANUAL mode of operation and manually manually position the valve over it’s it’s entire range. If the valve is stable in MANUAL mode then the problem can be noise in the control system. system. Recheck all wiring connections and ground points. points.
Compliance Voltage Voltage in Single Drop Current Mode The SVI II AP requires 9.0 Volts at 20 mA and 11.0 Volts at 4 mA. Typical HART devices require MORE Voltage at higher current curre nt and MORE current source have LESS Voltage available at higher current. The SVI II AP is unique in that it requires LESS Voltage at higher current which compliments the characteristic of the source requiring only 9 Volts at 20 mA.
Verify Wiring and a nd Connections Note: For split range installations the compliance voltage must be ca- pable of the minimum span being 5 mA; the upper range value must be 8 mA to 20 mA; the lower range values must be 4 mA to 14 mA. Use the following procedure to ensure that the SVI II AP is properly powered: Connect a DC voltmeter across the input terminals. For an input current between 4 and 20 mA the voltage varies between 11V and 9V respective. Current is read from the local display or with a milliammeter installed in series the SVI II AP. When voltage exceeds 11 V check that polarity is correct. If voltage is less than 9 V and polarity is correct, voltage compliance of current source is inadequate. Connect a milliammeter in series with the current signal. Verify Verify that source can supply 20 mA to SVI II AP input. If 20 mA is not attainable, troubleshoot the source and set up.

SVI-II (+) and (-) 4-20mA OUT Terminals These terminals provide a 4 to 20 mA signal related related to valve position. The 4 to 20 OUT terminals behave much like the terminals of a transmitter so a Transmitter type barrier with 250 Ohm series resistance (internal or external) is used for this connection. For example MTL 788 or 788R. Use of the 4-20 OUT feature is certified to ATEX intrinsically safe requirements and is approved for use in Zone Zone 0. Use of the 4-20 mA OUT feature has not been certified by FM or CSA. The 420 mA OUT feature may not be used in an intrinsically safe installation when FM or CSA intrinsically safe approval is required. The 4-20 mA OUT feature is certified by FM and CSA for use in a DIV 2 area and in a DIV 1 area when the SVI2 is installed in accordance with flameproof requirements. Entity Parameters: Vmax = 30 Vdc
Imax = 125 mA
Ci = 8 nF.
