About the Directive 2002/95/EC “RoHS” regulating the presence of certain hazardous
substances in electrical and electronic equipment
The Member States of the European Community are in the process of completing the
national reception and enforcement of the Directive 2002/95/EC regulating the presence of
certain hazardous substances in electrical and electronic equipment.
The Directive explicitly excludes from its scope of application finished products such as
those manufactured and sold by Marposs. It is still indeed a widely debated matter whether
the complete removal of the regulated substances could affect the reliability of the product.
Marposs shares in the social responsibility of continuously supporting every form of
innovation that reduces or minimizes any risk of adverse impact on human health and the
environment.
Marposs is therefore voluntarily pursuing the progressive removal of the regulated
substances from our products. Marposs will do so with the clear understanding that any
improvement achieved on the protection of health and the environment should not come as a
compromise for the quality and reliability of our products.
Marposs will put the greatest consideration in any initiative that our Customers
undertake with the purpose of reducing the environmental risk. Our commitment is the
support of their effort developing products that be of the highest quality and reliability.

10 1.Introduction – Programming Manual
1. INTRODUCTION
The Wheel balancing & Supervision process control allows continuous monitoring of
the grinding wheel condition with immediate compensation of possible unbalance
during the cycle.
It can be customized to a variety of applications and balancing heads.
1.1. Interface between Gauge and User
The software uses graphics and/or icons to show the various functions and make
comprehension and use easy and intuitive.
Other conventions used in this program are:
Numbers or text inside a dotted line can be changed.
Icons or text that appear as a phantom image (or grayed out) cannot be selected
on that page or are not available for the application and its options.
1.2. Programming manual
This guide was written for the gauge system programmer. It will also be useful for
plant personnel who must perform maintenance and for assistance technicians.
In order to make this guide easy to use, several typographical conventions were
chosen:
Folders, sub-folders and page names are in Italics.
Numbers or choices that can be changed are within quotes; i.e. “100 µm".
Front panel keys or software buttons are shown using the current icon.
Names of operator functions are followed by their icon.
