SAFETY PRECAUTIONS ON LASER PRODUCT
3) Class 2M laser products
Viewing the laser output with certain optical instruments designed for
use at a distance (for example, telescopes and binoculars) may pose an
eye hazard.
Follow the instructions mentioned in this manual. Otherwise, injury to the
human body (eyes and skin) may result.
• Do not stare into the beam.
• Do not direct the beam at other people or into areas where other
people unconnected with the laser work might be present.
• Be careful of the path of the laser beam.
If there is a danger that the operator may be exposed to the laser
beam reflected by specular or diffuse reflection, block the beam by
installing an enclosure with the appropriate reflectance.
• Install the products so that the path of the laser beam is not as
the same height as that of human eye.
• Do not disassemble this product. Laser emission from this
product is not automatically stopped when it is disassembled.
WARNING
5. Safety features provided with the LB-1000
series
The LB-1000 series is provided with the following safety features. Make
sure these features function correctly before operating.
1. Laser radiation emission warning
A visible LED informs you that the laser beam is being emitted, or is
about to be emitted, at least 3 second after power is provided to the
controller and the sensor head.
2. Laser emission delay
Laser emission only starts after the LED has been ON for at least 3
seconds, thus decreasing the possibility of laser exposure.
3. Laser emission stop input terminals
Terminals for controlling laser emission are provided on the controller.
You can remotely control laser emission using these terminals.
4. Key-operated switch
Set to the ON position to supply power. You can lock the power switch
using the supplied key; the key can be removed only when the switch
is set to the OFF position.
5. Beam attenuator
A laser beam shield is supplied. This cover is to be attached to the
laser-beam-emitting portion of the sensor head. If an operator must
work in front of the sensor head and there is risk to the eyes from the
laser beam, be sure to attach this cover.
