Adjusting sensor S2 in ISO versions
After replacing the sensor as described in paragraph 8.8.12, calibrate it as follows:
1. correctly attach a tool-holder before beginning the adjustment of the sensor;
2. check that, in this state, the output of S2 is “OFF”; if the output is “ON”, rotate the sensor unit
until it becomes “OFF”;
3. feed the air input for a tool change of the cylinder, using a one-way pressure regulator initially
set at 0 bar;
4. gradually increase the feed pressure so as to move the piston slowly forward and, at the same
time, check that the output of S2 is “OFF”;
5. as long as the tool-holder is firmly blocked, the output of S2 must be “OFF”; if the output
changes during the movement of the piston, slightly rotate the sensor unit until the output
returns to “OFF”;
6. when the tool-holder begins to slacken (but is not yet free to fall), the output of S2 must still be
“OFF” (if necessary, rotate the sensor unit);
7. when you reach the feed pressure at which the tool-holder is finally free to fall, increase the
pressure by another 0.2 bar and block the pressure regulator;
8. rotate the sensor unit so that, in this state, the output of S2 is “ON”, then fix it by tightening the
screw (3);
9. perform a cycle of 10 tool changes;
10. at the end of the cycle, check that the steps from [1] to [8] are satisfied, without the need to
ever rotate the sensor;
11. if the outputs requested are not satisfied, repeat the entire procedure from the start;
12. if the outputs requested are satisfied, perform a cycle of 100 tool changes with the machine,
using the maximum possible number of different tool-holders;
13. at the end of the cycle, check that the steps from [1] to [8] are satisfied, without the need to
ever rotate the sensor;
14. if the outputs requested are not satisfied, repeat the entire procedure from the start;
15. if the outputs requested are satisfied, the regulation procedure for S2 is complete.
