Laser Safety Switch
Safety switches cut power to the LD drive board when a
cover is opened.
Additional details:
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.
