3.3 Supply Cover and Safety Bar Check Switches
When the electromagnetic locks of the supply cover and the safety bar are
released, the load power of the X/Y beam on the pertinent side is shut off.

•
These switches are locked to prevent the supply covers and
the safety bars from being opened while the machine is
running. If the door or the bar is opened due to an
unaccountable error, the load power of the X/Y beam on
Side A (rear side) is shut off. (Stop in Error Condition)
•
The X/Y beam on Side A (rear side) cannot be moved with
the supply cover or the safety bar being opened.

4. Machine Protection Sensors
4.1 Lifted Feeder Detection Sensors
These sensors are used to prevent any machine operation (to protect the ma-
chine) when a tape feeder is not installed correctly.

When one of these sensors is turned off (E/NR: Light Emitted
and Not Received), the following measures are taken.
•
The power to drive both X/Y beams (Sides A beam and B
beam) is shut off.
4.2 Lifted Nozzle Detection Sensors
These sensors are used to protect the placement heads when a vacuum nozzle
is jerked out of the nozzle stocker while the X/Y beam is moving.

4.3 Beam Approach Detection Sensor
This sensor is used to detect that both X/Y beams are abnormally approaching
and protect the X/Y beam.
4.4 Stationary Position Stopper Detection Sensors
These sensors are used to check whether the stationary position stopper of the
X/Y beam has moved back during X/Y beam movement and the X/Y beam is
set ready to be moved.
