Indicates important facts and conditions.
SVI II AP Product Safety
The SVI II AP positioner is intended for use with industrial compressed air or, natural gas
systems only.
NOTE Installations using natural gas are Zone 0 or Div 1
installations.
Ensure that an adequate pressure relief provision is installed when the application of
system supply pressure could cause peripheral equipment to malfunction. Installation
must be in accordance with local and national compressed air and instrumentation codes.
Products certified as explosion proof or flame proof equipment or for use in intrinsically
safe installations MUST BE:
qInstalled, put into service, used and maintained in compliance with national and
local regulations and in accordance with the recommendations contained in the
relevant standards concerning potentially explosive atmospheres.
qUsed only in situations that comply with the certification conditions shown in this
document and after verification of their compatibility with the zone of intended use
and the permitted maximum ambient temperature.
qInstalled, put into service and maintained by qualified and competent professionals
who have undergone suitable training for instrumentation used in areas with
potentially explosive atmospheres.
Before using these products with fluids other than air or for non-industrial applications,
consult Dresser, Inc. This product is not intended for use in life support systems.
WARNING Under certain operating conditions, the use of damaged
instruments could cause a degradation of the performance of
the system, which can lead to personal injury or death.
Use only genuine replacement parts which are provided by the manufacturer, to
guarantee that the products comply with the essential safety requirements of the
European Directives.
Changes to specifications, structure, and components used may not lead to the revision
of this manual unless such changes affect the function and performance of the product.

Introduction
The SVI®II AP (Smart Valve Interface) is the next generation of Masoneilan’s intelligent
digital valve positioners. The SVI II AP is a high performance, digital valve positioner that
combines a local display with remote communication and diagnostic capabilities. The SVI II
AP offers a multitude of options that fulfills the broadest range of applications. It also
communicates using the HART®protocol.
An optional pushbutton and LCD display enables local operations of calibration and
configuration functions. Remote operations can be performed with ValVue®software or any
HART Registered host interface that has been pre-loaded with the Device Description file
(DD) for SVI II AP.
The SVI II AP is provided with Masoneilan’s ValVue software. The user-friendly interface
facilitates the setup and diagnostics of a control valve.

ValVue Software
Not only does ValVue provide the ability to quickly and easily set up the SVI II AP you can
also monitor operation and diagnose problems with ValVue’s advanced diagnostic
capabilities.
ValVue Lite
ValVue Lite software is shipped with each SVI II AP for positioner calibration and
configuration. ValVue Lite software is freeware and does not require any registration. It
provides functions to properly set up and start up an SVI II AP positioner on any type of
control valve.
System Requirements
ValVue Lite runs on IBM compatible computers. Minimum requirements for all versions of
ValVue software are Windows 2000, XP, 64 MB RAM, serial or USB port connected to a
HART®modem, and a CD-ROM drive.
ValVue Trial Version
The SVI II AP is provided with a trial version of ValVue. For 60 days after the initial
installation, ValVue provides the capability of configuring, calibrating, diagnosing, cloning,
trending and much more. After the 60 trial period ValVue must be registered for use.
ValVue is a user-friendly, graphical interface that allows an efficient setup of an SVI II AP
mounted on any control valve assembly. Because of its
What-You-See-Is-What-You-Get (WYSIWYG) software environment, it is a very simple
user-interface.
ValVue functionality includes:
qSetup Wizard
qRemote display of valve position, actuator pressure(s)
qSet calibration parameters
qSet configuration parameters
qMonitor status⁄error indicators
qInput/Output configuration
qRemote calibration of the SVI II AP
qRemote configuration of the SVI II AP
qRemote operation of the SVI II AP
qBackup and restore configuration (clone device)
qTrend setpoint, valve position, actuator pressure

Operational Overview Introduction
qDisplay comparative test results (full version only)
qPerform diagnostic test procedures (full version only)
Advanced and Online Diagnostics
The SVI II AP offers various levels of control valve diagnostics. Up to five pressure
sensors that detect circuit board temperature, loop current, and reference voltage, are
available for diagnostics.
For more details on the use of ValVue software, refer to the ValVue User’s Guide. Contact
Masoneilan or your local Masoneilan representative to obtain licensing information.

For the most recent software visit our SVI II AP web site at: www.masoneilan.com
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.
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.
SVI II AP Features
The SVI II AP Positioner (see Figure 1 on page -1) is suitable for installation indoors or
outdoors, and in a corrosive industrial or marine environment and is equipped with the
following features:
qExtreme Accuracy
qExtreme Reliability
qExtreme Digital Precision
qAutomated Valve Commissioning
