Safety Information for LV-S series
Safety precautions on laser products
* The classification is implemented based on IEC60825-1 following the
requirements of Laser Notice No.50 of FDA (CDRH).
Safety Measures for the Laser
■ Laser emission stop input
The laser emission can be stopped by selecting the “Laser emission stop”
signal (20 ms or more) from the input functions and inputting it externally.
The emission stops while the signal is being input. The laser beam is emitted
in 20 ms after the signal input is canceled. The control output functions
according to the received light intensity even while laser emission stop is
input.
Note
When the power is turned on, even when the laser emission stop signal is
input, the laser is emitted for about 60 ms for self-diagnostic purpose.
