Replacing the sensor unit
i
To replace and adjust the sensors illustrated in this and following paragraphs, refer again
to 812 and Figure8 13..
1.
Remove the screw (6) that blocks the bracket (5) of the sensor to be replaced (4).
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.
4.
Check the functioning of the new sensor by bringing it into contact with a metallic mass;
5.
Position the replacement sensor in the empty seat.
6.
Reposition the bracket (5) and tighten the screw (6) without blocking it completely, so that the
sensor can rotate, allowing the calibration operations described in the following paragraphs.
7.
After calibration, tighten the screw, blocking the sensor with an open-end spanner so as to
maintain the calibration carried out.
Do not grasp the sensor by the cable or the electrical connector!
To rotate it, use a monkey wrench measuring 12
To check the effectiveness of the adjustment, perform the maximum possible
number of tests with all the tool-holders available.
Warning: an incorrect calibration of the sensors can cause irregularities in the
functioning of the electrospindle.
