Installation manual for the EXTER series operator panels
Foreword
The EXTER operator panel is developed to satisfy the demands of
human-machine communication. Built-in functions such as displaying and controlling text, dynamic indication, time channels, alarm and recipe handling are included.
The operator panel work, for the most part, in an object-oriented way, making it easy
to understand and use. The configuration operation of the panel is made in a personal computer, using the configuration tool Information Designer. The project is then
transferred and stored in the operator panel.
The operator panel can be connected to many types of automation equipment, such
as PLCs, servos or drives. In this manual the expression “the controller“ is used as a
general term for the connected equipment.
This manual explains how to install the operator panel. Please refer to the reference
manual for further information.
