This section covers the optional local interface consisting of the LCD alphanumeric display and pushbuttons. Operation of the SVI II AP Digital Valve Positioner as a local device is controlled through the optional device-mounted pushbuttons and digital display, shown in Figure 7 on page 17. Using the display you can read the input signal, valve position, and actuator pressure. The display sequences from one variable to the next every 1.5 seconds.
Using the pushbuttons you can exit from operating mode at any time and step through a menu str
ucture to per
form a wide range of manual operation, calibration, configuration, and monitor­ing functions that are described later in this section. ValVue is used to perform all diagnostics functions. The pushbuttons do not support diagnostics f
unctions.
The SVI II AP has two operational modes: Normal Operating Mode and Manual Mode and two set­up modes, Configuration and Calibration. The SVI II AP also has two modes for handling of faults and power-up: R
eset and Failsafe. When commissioning or checking a control valve with SVI II
AP fully installed the following steps are recommended:
Change mode to Manual modeExamine and adjust all CONFIGuration itemsEnter Calibration modeRun STOPS to automatically calibrate strokeRun autoTUNE to set dynamic responseExamine the device STATUSIntroduce manual set point changes to verify dynamic performance
Pushbuttons
The local pushbuttons are located behind a hinged cover, directly below the display window. To open the cover loosen the screw and swing the cover down. Always re-fasten the cover after use to protect the pushbuttons from environmental contamination.
The three pushbuttons perform the following functions:
Left Button - Marked with *, permits you to select or accept the value or
parameter option currently displayed.
Middle Button - Marked , permits you to move back through the menu
structure to the previous item in the menu or decrement the value currently shown in the digital display. When used to decrease a displayed value, holding the button down causes the value to decrease at a faster rate.

Mounting the SVI II AP
This guide provides installation instructions for mounting an SVI II AP on both rotary and recipro­cating actuated valves. The mounting process can be broken down into the following:
Attach the mounting bracket to the actuator.Install the magnetic assembly.Assemble the SVI II AP on the mounting bracket.
NOTE The SVI II AP should be mounted with the conduit connections
down in order to facilitate drainage of condensate from the conduit.
Necessary Precautions
To avoid injury or the process being affected when installing or replacing a positioner on a control 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 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 v
alve’s Mounting Box kit

Mounting the SVI II AP on Rotary Valves
This section describes the procedure for mounting the SVI II AP on rotary control valves that have less than 60° rotation, such as a Masoneilan Camflex
*
II or a Masoneilan Varimax*. Figure 9
shows a side view of a Camflex actuator and the SVI II AP actuator mounting brackets.
Figure 9 Camflex with Mounting Bracket (Side View)
Mounting the SVI II AP on a Rotary Actuator
Tools required:
316" Hex Key532" Hex Key3 mm, 4 mm, 5 mm Hex Key716" Wrench
To mount the SVI II AP:
1. Attach the SVI II AP rotary mounting bracket to the valve actuator using two (2) 516 - 18 UNC flat
-head cap screws. In the pr
eferred mounting position, the long end of the mounting bracket is on your left when facing the actuator, for any position of the valve and actuator.
2. Bolt the extension shaft to the valve position take-off shaft using a 14 - 28 UNF socket flathead screw
. Secure the machine screw holding the extension shaft with
a torque of 144 in-lbs (16.269 N-m).
3. On internal valve pressure the thrust shaft is pushed out to the mechanical stops, usually a thrust bearing. On valv
es where the valve position take-off is mounted directly on the end of the plug shaft, a Camflex for example, the shaft must be bearing on its stop to properly set up the SVI II AP Controller. During hydrostatic testing the shaft is thrust to its stop and a normally tightened packing retains it in that position.
4. On vacuum service, the valve shaft may be drawn into the body by the vacuum acting on the shaft
, but the magnetic coupling must be assembled flush with the
mounting bracket with the shaft pulled f
ully out to its thrust bearing. Check that
the endplay from the vacuum position to the fully extended position is less than
0.06 in. (1.524 mm)
Page 23

.
5. Slide the magnet holder into the extension shaft. The location of the magnets is in the ring of the magnet holder. The magnetic axis is the imaginary line through the center of both magnets.
6. Rotate the magnet holder so that the magnet axis is vertical when the valve is in the closed position.
7. Align the end of the magnet holder flush with the end of the mounting bracket. Secure the magnet holder with two M6 set screws.
8. Slide the V-Seal over the magnet holder.
9. Secure the SVI II AP onto the mounting bracket using four M6 x 20 mm socket head cap screws.
10. Ensur
e no interference exists with the position sensor protrusion.
11. Ensure that the V-Seal makes contact with the skirt around the position sensor protrusion on SVI II AP housing.

Dismantling the SVI II AP from Rotary Valves
Before carrying out any work on the device, power off the instrument or ensure that the device’s location conditions for potentially explosive atmosphere permit the safe opening of the cover.
To remove the SVI II AP Controller from a rotary valve perform Steps 1 - 9 on page 22 in reverse.
Mounting the SVI II AP on Reciprocating Valves
The process of mounting the SVI II AP on a reciprocating valve consists of mounting the unit on the actuator that is attached to the valve. This section describes the procedure for mounting the SVI II AP on Reciprocating Valves (using Masoneilan’s 8788 Multi-Spring actuators as an exam­ple).
Mounting the SVI II AP on a Reciprocating Actuator
Tools required:
716" Combination Wrench (2 required)38" Combination Wrench12" Combination WrenchPhillips Head Screw Driver5 mm Hex Key Wrench
1. Ensure that the lever is pinned to the magnet assembly and held securely by an M5 flat head screw to ensure that the magnet axis is ver
tical when the lever is in
the valve closed position. Tighten the lever screw securely. Refer to Figure 10.

2. Mount the SVI II AP reciprocating mounting bracket to the actuator using two (2) 516 - 18 UNC cap screws.The mounting location of the bracket depends on the size and stroke of the actuator. Refer to Figure 11 and Figure 4 on page 28.
Figure 11 Reciprocating Valve Mounting Bracket
3. Select mounting hole A, B, C or D for the stroke of the valve. For example, hole B is shown in Figure 13 on page 27 for a size 10 actuator with 1.0" stroke. Unless otherwise specified, the SVI II AP mounting assumes that the actuator is in the normal upright position. The mounting hole in the slotted opening of the mounting brack
et must be left when facing the actuator, with the actuator in the upright
position.
4.
Move the valve to its closed position. For air to extend, this requires using air pressure in the actuator to f
ully stroke the actuator. For air to retract, actuators
vent the actuator of air pressure.
5. Thread the take-off rod to the actuator stem connector. Refer to Figure 12 on page 27. Ensure that the travel pointer located on the coupling is correctly positioned.
6. Attach the right hand threaded rod end to the SVI II AP lever using a 1⁄4 - 20 x 1" cap screw and nut as shown. The lever hole position to be used depends upon the specific v
alve stroke. Refer to Figure 13 on page 27 and the Reciprocating Valve
Linkage Selection, Table 4 on page 28.
7. Thread the right hand lock nut and turnbuckle onto the right hand rod end approximately tw
o turns. Turnbuckle length is a function of actuator size. (Refer to
Table 4 on page 28.)

Connecting the Tubing and Air Supply
The last step in hardware installation for the SVI II AP is to connect the air supply to the positioner. This section describes the process for connecting the tubing and air supply to a single and double acting positioner.
WARNING Isolate the valve from the process and disconnect air tubing from
the positioner. Disconnect air fully to avoid injury or process damage.
1. Install the tubing to the air supply port S
(arrow only for High Flow).
2. For a:
Single acting actuator: Pipe the outbound air from the output pressure port
 I (arrow only for High Flow) to the actuator.
Double acting actuator: Pipe output pressure port one I for one side of
the actuator and output pressure port two
II for the other side of the
actuator.
3. Air supply:

2. Turn on the air supply.
3. Adjust the filter regulator. Supply pressure must be 5 - 10 psi greater than the spring range of the actuator but may not exceed the rated actuator pr
essure. R
efer to the valve or actuator
instruction manual.
Wiring the SVI II AP
In order for the SVI II AP to communicate the positioner data the SVI II AP positioner must be physically connected to a HART® communication. The procedure below outlines wiring the SVI II AP.
WARNING Comply with current national and local regulations for electrical
installation work. Comply with national and local explosive atmosphere regulations. Befor
e carrying out any work on the device, power off the
instrument or make sur
e that the local conditions for potentially
explosive atmosphere permit the safe opening of the cover.
CAUTION Refer to B “Optional Switch Load Limits” on page 87 for guidelines
on safely wiring switch load limits.
Page 35

.
Connecting to the Control Loop
The SVI II AP digital valve positioner MUST BE grounded according to local regulations. It is im­portant to maintain correct polarity at all times, otherwise the positioner may not operate prop-
erly. Physically connect the SVI II AP to the HART
®
loop using a cable specified by the HART® Communication Foundation. A shielded cable is recommended. To connect the Control Loop to the SVI II AP:
1. Connect one end of the cable to the control loop's 4 - 20mA output
2. Remove the threaded wiring covers on the positioner.
3. 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 inser
t.
4. Maintain polarity + and - respectively.
Wiring Guidelines
This list contains guidelines for a successful implementation of DC current signal, DC power, po­sition Retransmit and HART
®
communication to the SVI II AP:
Compliance voltage at the SVI II AP must be 9 V 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.
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.Position Retransmit: when wiring this feature:
Wire using the same gauge wire as for the 4-20 mA control loop. In general, ensure that it is connected to the control system’s analog systems
card.
Ensure the control loop is powered when using a meter to make any
measurements.
NOTE For details and calculation methods for wiring resistance, and
capacitance and for calculation of cable characteristics, refer to the HART
®
FSK Physical Layer Specification.

SVI II AP Setups
Typical system setups are shown in Figure 19 on page 38, General Purpose and Explosion Proof (EEx d) Installation Schematic and Figure 20 on page 38, Intrinsically Safe Installation Schematic. The SVI II AP digital valve 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 adher
e to Electrical Installation section of manual and local electrical codes. The use of a Hand-
held Communicator or a HART
®
modem is not permitted in the Hazardous Area protected by Ex­plosion Proof (EEx d) methods. In Figure 20 on page 38 the SVI II AP digital valve 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 software and a HART® modem,
or from a HART
®
Hand Held Communicator. Since the process control system, the source of the input signal, is located in a non-hazardous location, setup requires an intrinsic safety barrier be placed between the process control system and the SVI II 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 flamepr
oof. SVI II AP can
communicate with a r
emote PC running ValVue software via a modem connected to the 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 valv
e 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 software, HART
®
Handheld Communi-
cator, or any registered HART
®
Host that supports DDs. The HART® Handheld Communicator is approved for Intrinsically Safe use in accordance with FM and ATEX standards. Read and observe all handheld labeling. 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. Reversing the 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 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 display cover and inside the 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 position the valve ov
er its entire range. If the valve is stable in MANUAL mode then the problem
can be noise in the control system. Recheck all wiring connections and ground points.

.
Compliance Voltage in Single Drop Current Mode
The SVI II AP requires 9.0 V at 20 mA and 11.0 V at 4 mA. Typical HART® devices require MORE Voltage at higher current and MORE current source have LESS Voltage available at higher cur­rent. The SVI II AP is noteworthy in that it requires LESS Voltage at higher current that comple­ments the characteristic of the source requiring only 9 V at 20 mA.
Verify Wiring and Connections
NOTE For split range installations the compliance voltage must be
capable 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 procedur
e to ensure that the SVI II AP is properly powered:
1. Connect a DC voltmeter across the input terminals.
For an input current between 4 and 20 mA the voltage varies between
11 V and 9 V respective.
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.
2. Connect a milliampmeter in series with the current signal.
3. Verify that source can supply 20 mA to SVI II AP input. If 20 mA is not attainable, troubleshoot the source and set up
.
NOTE Improperly or inadequately grounded installations can cause
noise or instability in the control loop. The internal electronic components are isolated from ground. Grounding the case is unnecessary for functional purposes but grounding the case may be necessary to conform to local codes.

Inspecting Actuator, Linkages, or Rotary Adapter
Verify that the mounting has not been damaged in shipment for a pre-mounted SVI II AP, physi­cally inspect the actuator, linkage. Record the following information for the configuration check­out:
1. Valve Air to Open (ATO) or Air to Close (ATC)
2. Actuator pressure rating
3. Actuator bench range
4. Inherent trim characteristic of the control valve; linear, equal percentage, or other.
NOTE Refer to the valve data sheet or model number of control valve.
Verifying Mounting and Linkage Adjustment
Inspect the mounting and make any needed adjustments before running the positioner and checking the digital configuration.
Checking the Magnet
There are two methods of checking the SVI II AP magnet:
Perform a visual inspectionUse ValVue to check the magnet
Performing a Visual Inspection
You must remove the positioner from the bracket to visually inspect the magnet orientation.
For rotary valves, such as a Camflex, or for actuators with rotation of less than 60°, the magnet assembly must be aligned as shown in Figure 21.
For rotary valves with rotations greater than 60°, the magnet assembly must be aligned as shown in Figure 22 on page 41.
NOTE For a reciprocating globe valve, it is not necessary to remove the
positioner from the bracket. Details are given below.
For reciprocating valves the adjustable link turnbuckle must be parallel to the valve stem. To en­sure linearity in positioning, verify that the hole in the lever aligns with the indicating hole in the brack
et when the valv
e is in the closed position. Check that the bracket is mounted using the
proper holes (refer to Table 4 on page 28).

Check-out with a HART® Handheld Communicator
If the SVI II AP is not equipped with optional push buttons and local display the checkout and con­figuration is performed using the standard HART
®
communications interface.
Connect the HART
®
handheld communicator to the SVI II AP as shown in Figure 27. Refer to the
product manual for the HART
®
communicator in use.
Figure 27 SVI II AP HART® Communicator Connections
Be sure that the configuration lock jumper is in the unlock position. When the jumper is in the lock position (shorting the two-pin header) the handheld is not permitted to make any changes. How­ev
er, parameters are readable. If fault messages appear, they must be handled before proceed-
ing with HART
®
communications. Before communications proceeds all error messages must be cleared. For example, the following message is displayed if the instrument has been serviced and the air is not connected.

SVI II AP Maintenance
The SVI II AP was designed based on a modular concept. All components are interchangeable allowing for easy, quick component swapping.
The only maintenance procedures recommended for the SVI II AP are:
Remove and install the coverRemove and install the I/P moduleRemove and install the pneumatic relayUpgrade to display cover
Do not remove the instrument cover or connect to an electrical circuit in a Hazardous Ar
ea unless the
power is disconnected.
If natural gas is supplied, natural gas may escape fr
om the SVI II AP on removal of the cov
er or
components.
Repair
Replacement of the Pneumatic Relay, I/P and cover (with or without display) are the only field re­pairs permitted.
Only qualified service personnel are permitted to make repairs.
Only factory-supplied parts are permitted. This includes not only the major assemblies but also mounting screws and O rings. No substitutions with non-Masoneilan parts are permitted.
Detailed r
eplacement procedures are described in the Instruction Manual. The following summa-
ry assures the integrity of the SVI II AP.

Installing the SVI II AP Display Cover
NOTE After replacing the SVI II AP display cover you must power up the
unit (see “Powering Up the SVI II AP” on page 44 of this guide).
The replacement display cover is shipped with a lanyard to prevent the cable (that connects from the display to the terminal board) from br
eaking. The lanyard must be inserted under the screw
in the lower left corner that attaches the terminal board to the SVI II AP housing.
To install the cover:
1. Install the lanyard and tighten the screw to 5 in/lb.
2. Using the 3 mm hex key, remove the screw from the lower left corner, connecting the terminal board to the SVI II AP housing.
3. Connect the cable fr
om the display into the LCD connector on the terminal board.
4. Ensure that the gasket is in its groove in the housing.
5. Place the cover over the screw mounts.
6. Tighten the four screws with the 5 mm hex key.
7. After installing the new display, power up the unit (refer to “Powering Up the SVI II AP” on page 44 of this guide for further information).
NOTE The cover of the SVI II AP is a critical component for safety in
Hazardous Areas. To ensure safe operation the flat surfaces of the cover and the housing must be clean and absolutely free of particles or dents. There must be no gap between the housing and cover; torque spec is 50 in/lb.
Ensure that:
1. The gasket is seated in the groove in the housing flange.
2. No wires or retaining cable can be trapped under the cover flange.
3. The flange area is not corroded and the surface is not scarred.
4. The four cover bolts are securely tightened to 50 in/lb.

SPECIAL INSTRUCTIONS FOR INSTALLING MASONEILAN
SVI-II AP IN AREAS WHERE THERE IS A POTENTIAL FOR EXPLOSIVE GAS
ATMOSPHERE OR INFLAMMABLE DUST
1 INTRODUCTION
This manual covers the requirements for safe installation, repair, and operation of the SVI-II AP as it relates to operation in areas where there is a potential for explosive atmosphere or inflammable dust. Adherence to these requirements assures that the SVI-II AP will not cause ignition of the surrounding atmosphere. Hazards related to control of the process are beyond the scope of this manual. For mounting instructions on specific valves refer to the mounting instructions supplied with the mounting kit. Mounting does not affect the suitability of the SVI-II AP for use in a potentially hazardous environment. The SVI-II AP is manufactured by:
Masoneilan Dresser Inc. 85 Bodwell Street Avon MA – 02322 – USA
2 GENERAL REQUIREMENTS
Installation and maintenance must be performed only by qualified personnel. Area Classification, Protection Type, Temperature Class, Gas Group, and Ingress protection must conform to the data indicated on the label.
Wiring and conduit must conform to all local and national codes governing the installation. Wiring must be rated for at least 5ºC above the highest expected ambient temperature.
!WARNING! Failure to adhere to the requirements listed in this manual may cause loss of life and property.
Page 68

68 | =GE Oil & Gas
ES-699 Rev AA Page 2 of 16
Approved wire seals against ingress of water and dust are required and the NPT fittings must be sealed with tape or thread sealant in order to meet the highest level of ingress protection.
Where the protection type depends on wiring glands, the glands must be certified for the type of protection required.
The metal housing is a die-casting alloy which is predominately aluminum.
Before powering the SVI-II AP:
1. Verify that the pneumatic and electronic cover screws are tightened. This is important to maintain the ingress protection level and the integrity of the flameproof enclosure.
2. If the Installation is Intrinsically safe, then check that the proper barriers are installed and the field wiring meets local and national codes for an IS installation. Never install a device, which was previously installed without an intrinsically safe barrier, in an intrinsically safe system.
3. If the pneumatic system is powered by a combustible gas then the installation must be treated as Zone 0 or DIV I.
4. If the Installation is Non-Incendive, then check that all the electrical connections are made to approved devices and wiring meets local and national codes.
5. Verify that the markings on the label are consistent with the application.
6. Verify that the air supply pressure cannot exceed the marking on the respective label.

9 Notes for Intrinsically Safe Installation
9.1 HAZARDOUS LOCATION
Refer to the device label for the description of the environment in which the device may be installed.
9.2 FIELD WIRING
Intrinsically Safe wiring must be made with grounded shielded cable or installed in grounded metal conduit. The electrical circuit in the hazardous area must be capable of withstanding an A.C. test voltage of 500 volts R.M.S. to earth or frame of the apparatus for 1 minute. Installation must be in accordance with Masoneilan guidelines. The installation including the barrier earthing requirements must comply with the installation requirements of the country of use.
Factory Mutual requirements (USA): ANSI/ISA RP12.6 (Installation of Intrinsically Safe Systems for Hazardous (Classified) Locations) and the National Electrical Code, ANSI/NFPA 70. Division 2 installations must be installed per the National Electrical Code, ANSI/NFPA 70. See also, note 4.
CSA requirements (Canada): Canadian Electrical Code Part 1. Division 2 installations must be installed per the Canadian Electrical Code Division 2 Wiring Methods. See also note 4.
ATEX requirements (EU): Intrinsically safe installations must be installed per EN60079-10 and EN60079-14 as they apply to the specific category.
9.3 SVI-II AP (+) and (-) 4-20 mA IN Terminals
These terminals power the SVI-II AP. The barrier is the Controller Output Type, for example MTL 728. Entity Parameters: Vmax= 30 Vdc; Imax=125 mA; Ci = 6.5 nF; Li = 1 uH; Pmax = 900 mW
9.4 SVI-II AP (+) and (-) 4-20mA OUT Terminals
These terminals provide a 4 to 20 mA signal 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 0. Use of the 4-20 mA OUT feature has not been certified by FM or CSA. The 4-20 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; Li = 1 uH max = 900 mW.

ES-699 Rev AA Page 13 of 16
9.5 SVI-II AP (+) and (-) PV 1-5VDC Terminals
The Process Transmitter and the SVI-II AP PV Input are both barrier protected. The transmitter 4 to 20 mA signal is converted to 1 to 5 Volts at the Transmitter barrier. The 1 to 5 volt signal is monitored by the DCS and used by the SVI-II AP for the embedded process controller. The sense resistor may be in the barrier or in the Digital Control System. The Process Transmitter must be approved for use with the Process Transmitter Barrier. An example of a suitable barrier is MTL 788 or 788R An example of the PV INPUT barrier is MTL 728. Entity Parameters of the SVI-II AP PV terminals:
Vmax = 30 Vdc; Imax = 125 mA; Ci = 1 nF; Li = 0 uH;
Pmax = 900 mW
9.6 SVI-II AP (+) and (-) SW Terminals
There are two independent isolated solid state switch contact outputs on the SVI-II AP. They are labeled SW#1 and SW#2. The switches are polarity sensitive – that is, conventional current flows INTO the plus terminal. An examples of suitable barriers are MTL 707, MTL 787 and MTL 787S. Entity parameters are: Vmax = 30 Vdc Imax = 125 mA Ci = 5 nF Li = 10 uH Pmax = 900 mW
9.7 SVI-II AP (1) and (2) and (3) REMOTE Terminals
The REMOTE terminals deliver reference Voltage to an optional remote position sensing potentiometer. Current, Voltage, and Power are limited by the SVI-II AP. The REMOTE terminals entity parameters are the parameters of the 4 to 20 mA INPUT barrier. The SVI-II REMOTE MOUNT is approved for use as a remote position sensing device with the SVI-II AP. SVI-II AP Entity parameters are:
Uo/Voc = 6.5 Volts Io/Isc = 9.6 mA Ca = 22 uF La = 300 mH Connect only to suitable potentiometer
SVI-II REMOTE MOUNT Entity parameters/Energy Limitation Parameters are:
Ui/Vmax=6.5Volts, Ii/Imax=10.5mA, Ci=0uF, Li=0, Pi=68mW
9.8 Digital In Terminals
The Digital In terminal is suitable for direct connection to a passive switch. Entity Parameters are:
Uo/Voc = 6.5 Volts Io/Isc = 72 mA Ca = 1.25 uF La = 2 mH
Connect only to passive (Un-powered) switch.

ES-699 Rev AA Page 14 of 16
9.9 Entity Requirement
Cable capacitance and inductance plus the I.S. apparatus unprotected capacitance (Ci) and inductance (Li) must not exceed the allowed capacitance (Ca) and inductance (La) indicated on the associated apparatus. If the optional Hand Held Communicator is used on the Hazardous Area side of the barrier, then the capacity and inductance of the communicator must be added and the communicator must be agency approved for use in the hazardous area. Also, the current output of the Hand Held Communicator must be included in the current output of the associated equipment. The barriers may be active or passive and from any certified manufacturer as long as the barriers comply with the listed entity parameters.
9.10 Use in dust atmosphere
Dust-tight conduit seal must be used when installed in dust hazard environments.
9.11 A device which has previously been installed without an approved IS barrier must NEVER be used subsequently in an intrinsically safe system. Installing the device without a barrier can permanently damage the safety related components in the device making the device unsuitable for use in an intrinsically safe system.

General Configuration Notes
The SVI II AP 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.
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. If the (+) terminal is electrically negativ
e with respect to the (–) terminal, then the switch will conduct.
Ther
e must be a series load in the circuit to prevent damage to the switch. If the switch is con-
nected directly across the power source the current will be limited only by the capacity of the power source and the switch can be damaged.
This section discusses the necessar
y precautions when configuring a system.

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 1 V. It is essential that the external circuit controls v
oltage such that the switch saturation voltage
is maintained.
When the switch is on (closed) the external voltage must be dropped across the load (Figure 30).
The load must be designed such that the current in the cir
cuit is
1 A at all times. Some 3rd party devices, such as incandescent lamps or solenoids, require surge and back EMI protection to limit current to 1 A.
