14. at the end of the cycle check that the table at point (11) is satisfied: if so the adjustment
procedure of S1 is finished; if not repeat the procedure from the beginning.
8.4.6 Adjustment of sensor S2 for ISO models
After having replaced the sensor as described in paragraph 8.4 , calibrate it as follows:
1. attach a tool holder properly before proceeding with the calibration of the sensor;
2. check that the output of S2 is "OFF" ; if the output is "ON" rotate the sensor unit until it turns to
"OFF" ;
3. feed the cylinder by means of a unidirectional pressure regulator, set initially at 0 bar (0 PSI);
4. increase the feed pressure in increments of 0.1 bar (1.5 PSI), to slowly advance the piston,
and at the same time check that the output of S2 is “OFF” ;
5. as long as the tool holder is firmly blocked, the S2 output must be "OFF" ;
if the output changes during the advance of the piston, rotate the sensor unit slightly until the
output returns to
"OFF" ;
6. when the tool holder begins to loosen, but is not yet free to fall, the S2 output must still remain
"OFF" (if necessary rotate the sensor unit);
7. when the supply pressure at which the tool holder is finally free to fall is reached, increase the
pressure further by 0.2 bar (3 psi), and block the pressure regulator;
8. rotate the sensor unit so that in this condition the S2 output is “ON”;
9. perform a cycle of 10 tool changes;
10. at the end of the cycle check that steps (1) to (8) have been verified without having to rotate
the sensor ;
11. if the requested output have not been verified, repeat the entire procedure from the
beginning;
12. if the requested output are verified, make the machine perform a cycle of 100 tool changes,
using the largest possible number of different tool holders;
13. at the end of the cycle check that steps (1) to (8) have been verified without having to rotate
the sensor ;
14. if the requested output have not been verified, repeat the entire procedure from the
beginning;
15. if the requested output have verified, the adjustment procedure of S2 is finished.
The sensors of the electrospindle ES327 are regulated by axially moving the sensor
instead of rotating it.
