Chapter 1. Introduction
1-1. Overviews
The SVX is an intelligent valve positioner that can be connected to a 4-20 mA controller
output signal line. Since all adjustments can be performed electrically, the relationship
between the input signal and the position of the control valve can be set arbitrarily. Split range
and other special settings are also easy to set up.
An overview of an SVX system is shown below.

1-3. Communication
There are three ways to communicate with the SVX: manually, using the Field Communication
Software (model CFS100) or using a HART communicator.
Manual configuration
Initial SVX configuration is typically performed using a switch Auto-Setup, which detect
the characteristics of the valve, as well as zero and span adjustment can all be performed
automatically.
Using the Field Communication Software (model CFS100)
Azbil Corporation’s Field Communication Software (model CFS100) can be used for all
configuration, calibration and maintenance of the SVX. SVX-original communicator
functions are documented fully in this manual. See the user's manual for model CFS100 to
learn more about the product.
Using a HART communicator
Emerson Electric HART communicator can be used for all configuration, calibration and
maintenance of model SVX102. SVX-original communicator functions are documented
fully in this manual. See the HART communicator manual to learn more about the HART
communicator.
According to need, update a software and device description files of HART communicator.

CAUTION
• Do not install the SVX near a large transformer, high-frequency furnace, or other
equipment that generates a magnetic field. Unexpected operation can result.
• Incorrect settings can reduce the SVX’s effectiveness and cause damage to or failure of the
SVX.
• When installing a control valve, provide adequate clearance around the valve for
maintenance (piping, wiring, and adjustment), and verify that the valve is oriented
correctly.
• Transport the SVX in its original packing to as close to the point of installation as possible.
• Do not apply excessive force to the feedback lever or bend the feedback pin when installing
the valve.
• Be sure to tighten bolts and nuts securely on the SVX and control valve.
WARNING
• To avoid physical injury, use caution when attaching the SVX.
• Be aware of sharp edges, such as the threaded edges of cover and any sharp edges on the
unit.
• The type and size of the actuator and the SVX settings determine the type of mounting
plate to be used. If you ordered your SVX with the actuator type specified, then the SVX
should come with the proper mounting kit, and the correct actuator settings should already
be programmed into the SVX. The Auto-Setup program is then used to calibrate the SVX.
