General, Safety, Transport and Storage General, Safety, Transport and Storage Information Operating Manual This manual contains important information regarding the handling of the device. For your own safety and operational safety, please ob- serve all safety warnings and instructions. Precondition for safe operation is the compliance with the specified safety and handling instructions. Moreover, the existing local accident prevention regulations and the general safety rules at the site of operation have to be observed. -
Page 5: Statement Of Warranties
General, Safety, Transport and Storage Statement of Warranties The producer guarantees the functional capability of the process engineering and the selected parameters. Demounting and Disposal Unless acceptance and disposal of returned goods are agreed upon, demount the device considering the safety instructions of this manual and dispose it with respect to the environment. -
Page 6: Conventional Use
General, Safety, Transport and Storage Conventional Use The product described in this manual was developed to execute safety-related functions as a part of an entire assembly or machine. It is the responsibility of the manufacturer of a machine or installation to ensure the proper functioning of the system. The ELGO-device is only conceived for the conventional use described in this manual. -
Page 7: Product Features
Product Features 3 Product Features The absolute shaft information system LIMAX02 M with its significant advantages is a particularly affordable, non-sensitive and easy-to-install alternative to conventional shaft information systems. Due to the absolute measurement principle, referencing is not required after commissioning. Compared to other shaft information systems, LIMAX02 M is characterized by an extraordinarily low price. -

Page 13: Description Installation / Mounting Of The Magnetic Tape
Installation and First Start-Up 5.2.1 Installation of the Sensor The sensor is fixated on the cabin or on the car frame. The mounting position is basically determined by the condition. The integrated mounting notch on the housing of the sensor head allow for a very simple and self- explanatory installation from one side. - Page 14 Installation and First Start-Up 5.3.2 Installation Concept 5.3.2.1 Basic principle for the mounting NOTE! The magnetic tape itself is not designed to withstand excessive mechanical wear. It is there- fore important to ensure that the system is installed such that the mechanical contact between tape and sensor head is mainly between the steel tape and the polymer sensor guide.
- Page 15 Installation and First Start-Up 5.3.3 Installation Procedure Attach the top end of the tape in the shaft head. Ideally use an ELGO Mounting Kit. Check for correct orientation of the tape. The arrows on the magnetic side must point in upward direction. Shaft head Shaft pit Fig.

- Page 17 Installation and First Start-Up IMPORTANT: Installation check! Values for tape tension and offset between tape and sensor are guidelines based on experience. But in any case, a proper check after installation is mandatory. It must absolutely be avoided that the magnetic side constantly grinds on the sensor body during operation.
- Page 18 Installation and First Start-Up If the installation check reveals that the tape slides on magnetic side, start to increase the offset between sensor and tape. Values of up to 5 cm are acceptable. If this measure does not solve the problem it is very likely that the tape is not plumb in the shaft.
