10. eject the tool-holder (piston forward) and check the S5 output is “OFF”;
11. bring the piston backward and check that, in this condition, the S5 output is “ON”. If this is not
the case, it means the sensor was moved too far forwards at point [
7] of this procedure;
repeat the entire procedure, making a finer adjustment at point [
7].
12. feed the tool-holder expulsion air inlet (piston forward) by means of a one-way pressure
regulator, set initially at 0 bar (0 PSI);
13. increase the supply pressure in increments of 0.1 bar (1.5 PSI), and simultaneously turn the
shaft by hand to check that it rotates freely and is not being held back by friction with the
piston;
14. when the shaft starts to brake by contact with the piston, the S5 output must become “OFF”
(pressure 0.5 bar). If this is not the case, it means the sensor was not moved far enough
forwards at point [
7] of this procedure. Repeat the entire procedure, making a greater
adjustment at point [
7].
15. if point (
14) of the procedure is met, perform 50 "tool-holder ejection (piston forward)" - "piston
return (piston backward)” cycles.
16. check the calibration by repeating steps [
10] to [15] of this procedure four times.
