Guarantee: The producer guarantees the functional capability of the process engineering and the selected parameters. The period of warranty is one year and begins with the date of delivery. -
Page 6: Conventional Use
General, Safety, Transport and Storage Conventional Use The ELGO-device is only conceived for the conventional use described in this manual. The EMAX-RO - ELGO- length measuring system only serves to measure lengths. CAUTION! Danger through non-conventional use! Non-intended use and non-observance of this operating manual can lead to dangerous situations. Therefore: Only use the device as described ... -
Page 7: Product Features
Product Features 3 Product Features The angle measuring system EMAX-RO is a combination of a sensor and a mag- netic ring. The magnetic ring is mounted directly to an engine shaft or an axle (see mounting suggestions 5.3). This ensures a quick and easy installation. EMAX-RO is especially suited for measuring rotative angles. -
