4.6.2 SAFETY SWITCHES FOR LASER UNIT
Laser
Exposure
LD Safety Switch
A safety switch turns off when the front cover or the rear door is opened. As a result, the relay
on the PSU cuts off the power supply (+5V) to the LD board. (The electric circuits go through the
engine board) This system prevents unexpected laser emission, and ensures user safety and
technician safety.
