1.3 SAFETY ITERLOCK
The laser system incorporates a safety interlock having an electrical potential of 24V DC
between terminals. When the top enclosure of the chassis is removed, the terminals of the
interlock connector at the front of the enclosure are no longer in contact and the laser beam will
be blocked by the shutter. A shorting plug, called an interlock defeat tool, is provided to over-
ride the safety interlock for testing and alignment procedures only. The diagram below is an
electrical schematic detailing the interlock system and the interlock defeat tool.
Caution:
The interlock defeat tool is utilized only when the top enclosure must be removed
for test purposes and beam alignments. Goggles must always be worn when the
defeat tools is in use.
DANGER
INVISIBLE LASER RADIATION WHEN OPEN
AND INTERLOCK FAILED OR DEFEATED.
AVOID EYE OR SKIN EXPOSURE TO
DIRECT OR SCATTERED RADIATION.
