The "incremental encoder kit", delivered in a plastic bag containing the following parts (Figure 1): An installation and wiring manual, An HENGSTLERB incremental encoder, 3 encoder fixing screws, M3 X 10, The incremental encoder fixing plate, The special tapping screw, allowing 3 different diameters, (Ml6 X 8 and Ml4 X 8, thread of 2 and Ml2 X 8, thread of 1,75) to be screwed into the thread recessed hole at the end of the motor shaft, The flexible coupling device training screw 1 encoder WARNING!!! Take account of the variety of gear and chassis, the "encoder kit" does not contain the linking piece between encoder fixing plate and the gear chassis! It is therefore up to you to make the adaptation specific to your requirements.

7 Documentation department Installation and wiring of incremental encoder Page 7 INSTALLATION OF INCREMENTAL ENCODER The present documentation presumes that the incremental encoder is fixed at the end of the traction motor shaft, from the wheel side to allow manual operation; this ought always be possible with new installations which must respect paragraph of the standard EN 81-1 : 6.3 Construction and equipment of machine rooms Dimensions The dimensions of machine rooms shall be sufficient to permit easy and safe working on equipment, especially the electrical equipment. In particular there shall be provided at least a clear height of 2 m at working areas, and: a) a clear horizontal area in front of the control panels and the cabinets. This area is defined as follows: 1) depth, measured from the external surface of the enclosures, at least 0,70 m ; 2) width, the greater of the following values : 0,50 m or the full width of the cabinet or panel ; b) a clear horizontal area of at least 0,50 m x 0,60 m for maintenance and inspection of moving parts at points where this is necessary and, if need be, manual emergency operation (12.5.1). If the installation configuration does not allow you to fix the encoder at the end of the motor shaft (especially when renovating the installation) you will have to study the coupling required (cardan system, angular reflexion or other). BEFORE BEGlNNlNG THE INCREMENTAL ENCODER ASSEMBLY, PLEASE INSURE THAT ONE OF THE THREE DIAMETER AND ALSO THAT THE THREAD OF THE SPECIAL TAPPING SCREW ARE CORRESPONDING TO THE THREAD OF THE RECESSED HOLE AT THE END OF THE MOTOR SHAFT!
