Laser LS8000-3 manual Laser Interlock Pin, Laser Interlock Input Circuit

LaserSpeed 8000-3 Instruction Handbook

Interfacing with the LS8000-3

Laser Interlock (Pin 16)

The Laser Interlock input will switch off the laser power when the connection to ground is broken. This is commonly used with external switches for laser safety. When the interlock pin is connected to ground, the laser is operational. When the interlock circuit is opened (break the connection to ground), power to the laser is switched off. The power to the rest of the LS8000-3 is not affected.

Note: To enable laser operation, connect the laser interlock pin (Pin 16) to ground (Pin 11, 19, or 21). There is a delay of several seconds from the time the Laser On light turns on to the time that laser radiation is emitted.
