Additional Laser Caution
The ON/OFF (ON: low level, OFF: high
level) status of the LPS1 (S601) switch for
detecting the loading state is detected by
the system microprocessor, and the
design prevents laser diode oscillation
when LPS1 (S601) is not ON (low level)
(clamped srate).
Thus, interlock will no longer function if
switch LPS1 (S601) is deliberately
shorted.
∗
In the test mode the interlock mechanism
will not function.
Laser diode oscillation will continue, if pin 2
of AN8849SB (IC201) on the MAIN
BOARD assy is connected to GND, or else
the terminals of Q201 are shorted to each
other (fault condition).
mechanism block removed to be turned
over, close viewing of the objective lens
with the naked eye will cause exposure to
a Class 1 laser beam.
