12.1.5 Sensor S5 adjustment
After replacing the sensor unit as described in section 12.1.2 , adjust it as follows:
1. correctly attach a tool holder before beginning the adjustment of the sensor;
2. supply 6 bar (87 PSI) to the cylinder so as to keep the piston at the upper end stop
3. position the sensor at the highest position allowed by movement (step 6 section 12.1.2 )
[“high” = direction opposed to the tool holder];
4. check that, in this condition, the output of S5 is “OFF”;
5. move the sensor downwards in small steps, until you find the position at which the output of
S5 becomes “ON”;
6. slightly move the sensor by another small step downwards;
7. lock the position of the sensor by tightening screw (3);
8. carry out 10 cycles of “tool expulsion” - “return to upper end stop”;
9. bring the piston to the upper end stop;
10. check that, in this condition, the output of S5 is “ON”;
11. free the input of the air to return the piston to the upper end stop in the cylinder;
12. feed the air input for “tool holder ejection” of the cylinder, using a one-way pressure
regulator initially set at 0 bar (0 PSI);
13. increase the feed pressure by 0.1 bar (1.5 PSI) steps and, at the same time, rotate the
shaft manually to check that it rotates freely and is not hampered by dragging against the
piston;
14. when the output of S5 becomes “OFF”, the manual rotation of the shaft must still be
absolutely free;
15. if the cylinder drags against the shaft when sensor S5 is still “ON”, this means that at point
[6] of this procedure, the sensor was advanced too far: repeat the whole procedure, making
much finer movements at point [6];
16. if point [14] of the procedure is satisfied, perform 50 “tool ejection” - “return to upper end
stop” cycles;
17. check the adjustment, repeating steps [9] to [16] of this procedure four times.
