General, Safety, Transport and Storage 4 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 instruc- tions.
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.
General, Safety, Transport and Storage Conventional Use The ELGO-device is only conceived for the conventional use described in this manual. The ELGO linear encoder IMAX only serves to measure lengths and positions. CAUTION! Danger through non-conventional use! Non-intended use and non-observance of this operating manual can lead to dangerous situations.
Pseudo-absolute value with a reso- lution of 1 mm. The designation of the respective ELGO magnetic tape type depends on the output interface used. For more information, refer to the technical data 6.3.
The type label serves for the identification of the unit. It is located on the housing of the device and indicates the exact type designation (= order reference 10) with the corresponding part number. Furthermore, the type label contains a unique, traceable device number. When corresponding with ELGO please always indicate this data.

Installation 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. The operator is obliged to take appropriate safety measures.
7.2.1 The Magnetic Tape For IMAX with CANopen interface the absolute coded ELGO magnetic tape AB20-80-10-1-R-17 must be used, while for versions with SSI interface the type AB20-80-10-1-R-15 is required. The two magnetic tape types only differ in their coding (CANopen = 17 bit / SSI = 15 bit).
Installation and First Start-Up 7.2.2 Handling In order to avoid tension in the tape, it must not be stretched, compressed or twisted. It should be stored with the magnetized plastic tape to the outside. The minimum bending radius is 150 mm. Magnetized plastic tape Steel tape...
Installation and First Start-Up Mounting steps: 1. Thoroughly clean the surface ( 7.2.3) 2. Acclimatization: let magnetic tape and cover tape adjust their temperature 3. Remove the protection foil from the magnetic tape 4. Glue magnetic tape under great pressure 5.
As shown in the following figure, the tape consists of a 8 mm wide magnetic tape which is connected to a 10 mm wide back iron stripe. The cover tape is not supplied with this variant.

Installation and First Start-Up Installation of the Sensor Fasten the sensor with two M3 cylinder head screws of suitable length (see 6.2). For absolute coded magnetic tapes it is important that the sensor is mounted in the correct direction to the tape. Otherwise no measurement is possible.
Installation and First Start-Up 7.4.2 Mounting Tolerances REMARKS! Ensure correct distance sensor / magnetic tape 0.1 mm ... max. 1.8 mm! The LED on the sensor housing lights up red as soon as this distance is exceeded. The cable outlet of the sensor points towards the counting direction (see section 7.4.1.) ...
Connections and Interfaces 8 Connections and Interfaces CANopen Interface (CAO0) When ordering the CA0 interface option, the IMAX measuring system is equipped with a CAN interface accord- ing to CANopen standard DS406 for encoder device profiles. The CAN interface is terminated internally with a 120 Ω terminating resistor as standard. If no internal termina- tion is required, the additional option "A"...
Connections and Interfaces SSI Interface (SSB0 and SSG0) Principle of the function: If the clock is not interrupted for the time Tm-T/2 (output of further 25 periods), the shift register clocks once again the same data value (error recognition in evaluation). With the SSI interface, trans- mission frequencies up to max.
Disturbances, Maintenance, Cleaning 9 Disturbances, Maintenance, Cleaning This chapter describes possible causes for disturbances and measures for their removal. In case of increased disturbances, please follow the measures for fault clearance in chapter 9.1. In case of disturbances that cannot be eliminated by following the advice and the fault clear- ance measures given here, please contact the manufacturer (see second page).
