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.
