7.1.14 Nozzle Detection Sensor (ST15)
Point
Station 15 uses three nozzle detection sensors to detect which of the six nozzles (No. 1
~ 6) is down.
The following illustration shows the 3 sensors.
Sensor Position Adjustment
1 Press the EMERGENCY STOP button to take the 200V down to 100V.
2 Remove the nozzle holders of the reference head and the adjacent heads.
3 Use the inching keys to move the reference head to ST13.
4 Use the cam handle to rotate the cam to 200°.
5 Remove the reject parts brush.
WARNING
• Press EMERGENCY STOP before performing this procedure.
• Exercise extreme caution when working on the machine if the cam
is not at its origin (0 deg.). Spring recoil can rotate the cam inde-
pendently.
