LD Safety Mechanisms

Laser Safety Switch
There are safety switches on the front and rear covers. These switches stop the laser
while the cover is open. If the user opens one of these covers, the +5VLD power to the
laser diodes is stopped.
Laser Shutter
The laser shutter [A] is for back-up safety. If the switches do not work, the +5VLD power
gets to the laser diodes if the cover is open.
The laser shutter cuts the laser beam when the front cover is open.
