Operational Overview
The SVI II AP is a smart electro-pneumatic positioner that receives a
4 - 20 mA electrical position setpoint signal from the controller and compares the position
setpoint input signal to the valve position feedback sensor. The difference between the
position setpoint and position feedback is analyzed by the position control algorithm that
sets a servo signal for the I/P converter. The output pressure of the I/P is amplified by a
pneumatic relay that drives the actuator. Once the error between the setpoint and the
valve position feedback is within range, no other correction is applied to the servo signal
in order to maintain valve position.
Introduction
The local explosion proof LCD/Buttons (if equipped) display provides configuration or
calibration mode in all operating environments. The limit switch⁄transmitter options board
provides contact outputs that are software configurable, and an analog (4 - 20 mA)
position feedback.

Mounting the Positioner
8/10
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:
q Attach the mounting bracket to the actuator.
q Install the magnetic assembly (rotary only).
q Assemble the SVI II AP on the mounting bracket.
DRAFT 6/
Necessary Precautions
To avoid injury or the process being affected when installing or replacing a positioner on a
control valve, ensure that:
q 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.
NOTEMount the SVI II AP with the conduit connections down in
order to facilitate drainage of condensate from the conduit.
q Shut off air supply to the actuator and to any valve mounted equipment.
q 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.
q Purge air from actuator and check that valve is in its unenergized position.
12
Filter Regulator and Tubing
Filter Regulator and Tubing
The use of a Masoneilan filter regulator with a 5-micron filter is recommended for the air
supply. Use 1⁄4" (6.35 mm) minimum tubing between filter regulator, SVI II AP and the
actuator, with 3⁄8" (9.53 mm) used for larger actuators. Use a soft setting anaerobic
hydraulic seal such as Loctite Hydraulic Seal 542 for sealing the pneumatic pipe threads.
Follow manufacturers instructions.
NOTEMaximum allowable air supply pressure to the SVI II AP
varies according to actuator and valve size and type. See
pressure drop tables in valve specification sheets to
determine correct positioner supply pressure. Minimum
supply pressure should be 5 to 10 psi
(.345 bar - .69 bar) (34.485 - 68.97 kPa) above maximum
spring pressure.
Mounting the SVI II AP on Rotary Valves
Installation and Set
This procedure is used to mount the SVI II AP on rotary control valves that have less than
60° rotation, such as a Camflex
60° refer to “Rotary - 90°” on page 16
Required Tools
The following tools are needed to complete the rotary valve installation:
q 3⁄16" Hex Key with tee handle
q 5⁄32" Hex Key
q 3 mm, 4mm, 5mm Hex Key
q 7⁄16" Wrench
To mount the SVI II AP:
1. Attach the SVI II AP rotary mounting bracket t o the valve a ctuator using two (2) 5⁄16 -
18 UNC flat-head cap screws. Mount the SVI II AP as shown in Figure 5 on page 15,
ATO or in Figure 6 on page 15, ATC. In the preferred 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.

DRAFT 6/8/10
2. Bolt the extension shaft to the valve position take-of f shaft using a 1⁄4 - 28 UNF socket
flathead screw . Secure the machine screw holding the extension shaf t with a torque of
144 in-lbs (16.269 N-m).
3. Upon internal valve pressure the thrust shaft is pushed out to the mechanical stops,
usually a thrust bearing. On valves 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 positioner. During hydrostatic testing the
shaft is thrust to its stop and a normally tightened packing retains it in that position.
13
Dresser Masoneilan
4. On vacuum service, the valve shaft can 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 fully out to it s thrust bearing. Check that the end play from
the vacuum position to the fully extended position is less than 0.06 in. (1.524 mm)
5. Slide the magnet holder into the extension shaft. The location of the magnet s 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. See Figure 5 and Figure 6.
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. Ensure 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.

Magnet Orientation on Rotary
Magnet Orientation on Rotary Valve Shafts
The same mounting hardware is used for Models 35, 30 actuators. For each actuator type
the magnetic coupling must be properly oriented to the active sensing angle of the
positioners Hall Effect sensor . The active range of the Hall-Effect sensor is plus⁄minus 70°
from the null magnet axis. If the total valve travel is less than 60°, allowing a margin for
tolerances, the best accuracy is achieved by mounting the magnet with the axis vertical in
the valve-closed position. Note the location of the magnets in the ring of the magnet
holder. The axis of the magnets is the line through the centers of both magnets. Mount
the magnet holder with the magnet axis vertical on the 35, 30 when the valve is clo sed. If
travel of the valve exceeds 60°, the magnet must be assembled to the rotary valve shaft
so that the magnet axis is vertical when the valve is at mid-scale.
Dismantling the SVI II AP from Rotary Valves
WARNINGBefore carrying out any work on the device, power off the
instrument or make sure that the device’s location conditions
for potentially explosive atmosphere permit the safe opening
of the cover.
Installation and Set
To remove the SVI II AP positioner from a rotary valve perform Steps 1 - 8 on page
page 10 in reverse.
Mounting the SVI II AP on Reciprocating Valves
This section describes the procedure for mounting the SVI II AP on Reciprocating Valves
(using Masoneilan’s 87⁄88 Multi-Sp ring actuators as an example).
Mounting the SVI II AP on a Reciprocating Actuator
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 vertical when the lever is in the valve
closed position. Tighten the lever screw securely.
DRAFT 6/8/10
2. Mount the SVI II AP reciprocating mounting bracket to the actuator using two (2) 5⁄16
- 18 UNC cap screws. The mounting location of the bracket depends on the size and
stroke of the actuator. Refer to Figure 9 on page 19 and Figure 3 on page 19.
17
Dresser Masoneilan
3. Select mounting hole A, B, C or D for the stroke of the valve. For example, hole B is
shown in Figure 10 on page 19 for a size 10 actuator with 1.0" stroke. Unless
otherwise specified, the SVI II AP mounting assumes that th e actuator is in the normal
upright position. The mounting hole in the slotted opening of the mounting bracket
must be left when facing the actuator, with the actuator in the upright position.
4. Thread the take-off rod to the actuator stem connector . Refe r to Figure 11 on pa ge 20.
Ensure that the travel pointer located on the coupling is correctly positioned.
5. 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 valve stroke. Refer to Figure 10 on page 19 and the Reciprocating Valve
Linkage Selection, Table 3 on page 19.
6. Thread the right hand lock nut and turnbuckle onto the right hand rod end
approximately two turns. Turnbuckle length is a function of actuator size. (Refer to
Table 3 on page 19.)
7. Secure the magnet housing assembly, including the lever and right hand rod end, to
the bracket using four M5 X 10 mm flat head screws.
SVI II AP Instruction Manual
8. Attach the left hand threaded rod end to the take-off rod with
1⁄4 - 20 UNC nut and thread the left hand lock nut onto the rod end.
8/10
DRAFT 6/
9. Move the valve to its closed position. For air to extend, this requires using air pressure
in the actuator to fully stroke the actuator . For air to retract, actuators vent the actuator
of air pressure.
10. Thread the turnbuckle onto the left hand threaded rod end. Refer to Figure 11 on
page 20.
11. Adjust the turnbuckle until the hole in the SVI II AP lever is aligned with the indicating
hole in the bracket. Tighten both turnbuckle lock nuts. (See Figure 9 on page 19.)
12. Mount the SVI II AP to the bracket and secure with four M6 socket head cap screws.
