Introduction
Thank you for purchasing our AVP702 Smart Valve Positioner. The AVP702 (called “the
device” below) is a smart valve positioner that can be connected to the 4 to 20 mA loop.
The auto setup function makes it easy to set up the valve.
All adjustments and setup can be performed from the HART communication. The Local
User Interface (LUI), which consists of the LCD (liquid crystal display) and operation
buttons, facilitates monitoring of input signals, valve opening, pressure display, and other
items as well as basic adjustments.
In addition, the built-in pressure sensor can be used to measure the supply air pressure
and output air pressure. As a result, the device can not only perform self-diagnostics but
can also be combined with the control valve maintenance support system called “Valstaff”
in order to monitor the characteristics, operating status, and other data of the control
valve, helping to improve the maintenance efficiency of control valves. This instruction
manual describes how to handle the device. Read this manual to make full use of the
features of this product.
