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.

Chapter 1 Structure of the 700 Series Control System
This chapter describes the device configuration of the control system that uses the
device.
• Description of the configuration of the input/output system in the device
• Description of the structure of the main unit of the device and the name and function of
each part
1-1 System Configuration
This device is a smart valve positioner that can be connected to the 4–20 mA DC signal
lines of the controller output. It makes various adjustments using electricity, so the
relationship between input signals and control valve travel can be set to any desired
value. In addition, by connecting the device using four lines, the control valve travel is
transmitted to the host monitoring system as a 4–20 mA DC analog signal. (Only the
AVP701 model supports valve travel transmission.)

This device (model AVP701) has a function for motion transmission of the control valve.
To output the travel signal to the host monitoring device using analog values, configure
the system with motion transmission. Normally, the travel from fully closed to fully open
are output as 4–20 mA DC.
This shows an example of a system configuration for outputting valve travels detected
with this device as 4–20 mA DC analog signals.
With this system configuration, analog signals are output directly to the higher-order host
monitoring system from this device.
