Precondition for safe operation is the compliance with the specified safety and handling instruc- tions.
Page 6: 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 7: Conventional Use
General, Safety, Transport and Storage Conventional Use The ELGO-device is only conceived for the conventional use described in this manual. The HMIX2 - ELGO- length measuring system only serves to measure lengths and distances. 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 8: Product Features
Product Features 3 Product Features The HMIX2 is an incremental magnetic length measuring system. The sensor technology and translator circuit are placed in the same small housing. The magnetic tape can also be fixed into a guiding rail by using the pro- vided adhesive tape.
Page 9: Technical Data
Technical Data 4 Technical Data Identification 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,  8) with the corresponding part number. Furthermore, the type label contains a unique, traceable device number.

Installation and First Start-Up 5 Installation and First Start-Up CAUTION Please read the operating manual carefully before using the device! Strictly observe the Instal- lation instructions! In case of damage caused by failure to observe this operating manual, the warranty expires. ELGO is not liable for any secondary damage and for damage to persons, property or assets.
Page 14: Installation Of The Magnetic Tape
Installation and First Start-Up Installation of the Magnetic Tape NOTE External Magnetic Fields The magnetic tape must not be influenced by external magnetic fields! The magnetic tape must not come into direct contact with other magnetic fields (e.g. perma- nent magnets, magnetic clamps, electromagnets, magnetic stands)! This may cause irrepara- ble damage, which will compromise the measuring accuracy or even the functioning.

Page 20: Alignment Hmix2 Sensor / Magnetic Tape
Installation and First Start-Up Alignment HMIX2 Sensor / Magnetic Tape 5.6.1 Alignment - Standard (without Reference Pulse) Since the sensor housing is 2.5 mm wider than the 10 mm wide magnetic tape, make sure that the sensor co- vers the tape far enough inwards. To do so, simply use the correct side of the sensor (see figure below) and install it flush with the magnetic tape.
Page 21 Installation and First Start-Up 5.6.3 Alignment - Option R combined with “RS1” (Accessory) If the HMIX2 is equipped with a reference pulse sensor (option "R"  8.1) and a separate reference pulse plate- let “RS1” (accessory  8.4) is used, the HMIX2 sensor, the magnetic tape and the RS1 platelet must be installed as shown in the figure below.
