General 4 General 4.1 Information Operating Manual This manual contains important information regarding the handling of the device. For your own safety and op- erational safety, please observe 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 6: Statement Of Warranties
General Statement of Warranties The statement of warranties is enclosed separately in the sales documents. 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. 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 7: Safety
Safety 5 Safety CAUTION! Please read the operating manual carefully, before using the device! Observe the installation instructions! Only start up the device if you have understood the operating manual. The operating company is obliged to take appropriate safety measure. The initial operation may only be performed by qualified and trained staff. -
Page 8: Conventional Use
It is the responsibility of the manufacturer of a machine or installation to ensure the prop- er operation of the system. The ELGO-device is conceived only for the intended use described in this manual. The LIMAX2M - ELGO- length measuring system serves only to measure lengths. -

Page 10: Product Features
Product Features 7 Product Features The absolute shaft information system LIMAX2M with its significant advantages is a particularly affordable, non- sensitive and easy-to-install alternative to conventional shaft information systems. Due to the absolute measure- ment principle, referencing is not required after commissioning. Compared to other shaft information systems, LIMAX2M is characterized by an extraordinarily low price. -
Page 11: Technical Data
The type label serves for the identification of the unit. It is located on the housing of the sensor and gives the exact type designation (=order reference, see type designation) with the corresponding part number. Further- more, the type label contains a unique, traceable device number. When corresponding with ELGO always indicate this data. Dimensions Sensor Figure 2: Dimensions LIMAX2M... -

Page 16: Description Installation / Mounting Of The Magnetic Tape
Installation and First Start-Up 9.2.1 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 17 Installation and First Start-Up 9.3.2 Installation Concept 9.3.2.1 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 18 9.3.3 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...

- Page 20 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 21 Installation and First Start-Up If the installations 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.
