4.2.2 Lifted Nozzle Detection Sensors

These sensors are provided to protect the placement heads when a

vacuum nozzle is ejected out of the nozzle stocker.

When one of these sensors is turned OFF (light emit-

ted and not received), the following measures are taken.

• The excitations of the beam X/Y axis and the nozzle

U/D axis are shut off.

(At the same time, the nozzle U/D axis is braked.)

4.2.5 Excessively Inserted Nozzle Detection Sensors

These sensors are provided to protect the placement heads against

any vacuum nozzle that is excessively inserted due to an error in the

pattern program.
