4.1.4 Maintenance Opening Detection Sensors
Whenever a foreign object (hand, fingers, etc.) is detected between the
safety door and a feeder during operation, these sensors are provided
to stop the X/Y beam for safety purposes.

When one of these sensors is turned OFF (light emit-
ted and 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 Module Protection Sensors
This session describes the main sensors that are provided for ma-
chine protection.
4.2.1 Mispicked Component Detection Sensors
These sensors are provided to detect mispicked components, etc., at
the component pick-up position for the protective purposes of the ma-
chine.

• The excitations of the beam X/Y axis, the nozzle U/D
axis, and the head rotational axis are shut off. (At the
same time, the nozzle U/D axis is braked.)
• The nozzle change axis stops rapidly after the sen-
sor has detected a mispicked component.

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.
