LD Safety Switch

4
A safety switch turns off when the front cover or the right door is opened. As a result, the relay on the
PSU cuts off the power supply (+5V) to the four LD boards. (The electric circuits go through the EGB and
IOB) This system prevents unexpected laser emission, and ensures user safety and technician safety.
