Introduction
Thank you for purchasing our AVP703 Smart Valve Positioner. The AVP703 (called
“the device” below) is a smart valve positioner that can be connected to the Foundation
Fieldbus.
The auto setup function makes it easy to set up the valve.
All adjustments and setup can be performed from the Foundation Fieldbus host. 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.
