<strong>HSD</strong> 12.1 REPLACEMENT AND ADJUSTMENT OF THE SENSOR GROUP For the position of sensors see the paragraph 8.1 . 12.1.1 Description of the sensor unit The sensors are pre-assembled in calibrated bushes to allow simple insertion to the right depth in the electrospindle. It is therefore important to correctly identify the sensor to be replaced: for this reason, both the sensors installed on the electrospindle and those supplied as spare parts bear a numbered label (Image 12-1). Confusion of the sensors will result in damage to the moving parts. 1 Image 12-2 Sensor fastening through bracket Image 12-1 5801H0066 en Rev.01 38/48 9 3 6 8 4 7 2 Ch 12 Image 12-3 Sensor fastening through block 1 Electrical connector 6 Calibrated position 2 Eccentricity marking 7 Bracket or block 3 Bush 8 Sensor unit 4 Sensor 9 Screw Eccentricity between 5 regulation sensor bush and 5
<strong>HSD</strong> 12.1.2 Replacement and adjustment of the sensor unit i For the replacement and adjustment of the sensors shown in this paragraph (and those to follow), always refer to Image 12-1; Image 12-2; Image 12-3 of the previous paragraph. 1. Remove screw “9” that blocks the bracket or block “6” of the sensor unit “8” to be replaced; 2. unthread the faulty sensor unit from its seat, and disconnect its electrical connector “1”; 3. connect the electrical connector of the new sensor unit to the correspondingly numbered connector of the spindle; 4. check the functioning of the new sensor by bringing it into contact with a metallic mass; 5. Insert the new sensor unit in the empty seat; 6. reposition the bracket “7” and lock the screw “9” again without tighten it completely, so that the sensor unit can rotate; 7. rotate the sensor unit a few degrees at a time, until you obtain the outputs requested in the paragraphs immediately below; 8. tighten the screw “9” by blocking the sensor unit with an open-end spanner so as to maintain the calibration carried out. 12.1.3 Sensor S1 adjustment After replacing the sensor unit as described in section 12.1.2 , adjust it as follows: 1. do not tighten the sensor completely until an accurate adjustment has been performed; 2. attach the tool holder cone and ensure that the output of S1 is “ON”; if the output is “OFF”, rotate the sensor unit until it becomes “ON”; 3. the sensor “4” is eccentric in relation to the bush “3” that contains it: rotate the bush slowly in the direction that takes the sensor away from the tool holder; stop immediately when the output of the sensor becomes ”OFF”; 4. carefully rotate the bush back by about 15° - 20°, so that the output of the sensor returns to “ON”; 5. rotate the shaft manually, and check that the signal remains “ON” for the whole rotation; 6. tighten fixing screw “9”; 7. release the tool holder by powering the piston at the pressure indicated in the section 8.1 and check that in this condition (collet open) the output of S1 is “OFF”; 8. release the pressure at the piston and allow the collet to close without tool holder: in this condition, the output of S1 must be “OFF” for the whole rotation of the shaft; 9. if points (7) and (8) are not satisfied repeat the procedure from the start, making an even slighter rotation movement at point (4);; 10. if points (7) and (8) are satisfied, make a cycle of 10 tool changes; 11. at the end of the cycle, check that the conditions in the following table are satisfied: CONDIZIONE OUTPUT S1 tool holder locked ON (*) missing tool holder with closed collet collet open (tool holder ejected) OFF OFF (*) (*) for the whole rotation of the shaft 12. if the conditions of the table are not satisfied, repeat the procedure from the beginning; 13. if the conditions of the table are satisfied, perform a cycle of 100 tool changes with the machine, using the maximum possible number of different tool holders.; 14. At the end of the cycle, check that the conditions in the table under point (11) are satisfied: if this is the case, the regulation procedure for S1 is complete; if this is not the case, repeat the procedure from the beginning. 5801H0066 en Rev.01 39/48
