Additional Laser Caution
1. Laser Interlock Mechanism
The position of the switch (S9002) for detecting loading
completion is detected by the system microprocessor, and the
design prevents laser diode oscillation when the switch is not in
LPS1 terminal side (when the mechanism is not clamped and
LPS1 signal is high level.)
Thus, the interlock will no longer function if the switch is
deliberately set to LPS1 terminal side.
( if LPS1 signal is low level ).
In the test mode
∗
the interlock mechanism will not function.
Laser diode oscillation will continue, if pin 5 (pin 3) of
A
N 22022A (IC7002) on the SR V A Assy is connected to G N D,
or else the terminals of Q7002 (Q7001) are shorted to each
other (fault condition).
2. When the cover is opened, close viewing of the objective lens
with the naked eye will cause exposure to a Class 1 laser beam.
