Overview
Legend
1. Transmitter module (amplifier) with 2 screws
2. Transmitter module (round laser diode) with 3
screws
DANGER: The laser light barrier
emits class 2 laser beams (from its
transmitter).
You therefore do not require additional
protective measures!
X Keep your eyes away from the laser
beam!
NOTE:
After setting the laser light barrier you
must check or re-teach the PCB
reference corner!
X Move the PCB conveyor to the position which
gives you best access to the laser light barrier.
X Move the Y gantries into the area outside the
PCB conveyor.
X Switch off the machine and secure it to prevent
unauthorized reactivation.
