Laser Safety Interlocks
The Option Bay has five laser safety interlocks that prevent the laser from
firing when any safety shield on the Option Bay is removed. To physically
enable the laser, all laser safety interlocks must form a complete electrical
circuit to the laser’s safety inhibit input. When activated, (i.e., when any
safety shield is removed) the safety interlock disables the laser’s safety
inhibit circuit. Activation of the safety interlock prevents (via hardware in
the laser itself) the laser from firing. A laser safety interlock is shown in Fig-
ure .
Figure 1-12—Laser safety interlock
The five laser safety interlocks are located:
1. Behind the removable safety shield on the front (toward the PS288) of
the Option Bay
2. Behind the removable safety shield on the upper left side of the Option
Bay
3. Behind the removable safety shield on the top of the Option Bay
4. Behind the removable safety shield on the upper right side of the
Option Bay
5. Behind the removable safety shield on the lower left side of the Option
Bay

The laser safety interlocks can be overridden for service. To override a laser
safety interlock, pull out on the switch. The laser can now fire with the safety
shield removed.

by qualified and trained service personnel.
WARNING: Never leave system unattended with safety shield
removed and safety interlocks overridden. Serious burn hazard!
Direct or diffuse laser radiation can cause serious burns. Blind-
ness hazard! Direct or diffuse laser radiation can damage eyes.
