1.4 Safety Consideration
Use of controls or adjustments or the performance of procedures other than those
specified herein may result in hazardous radiation exposure.
The laser beam is not harmful to the skin. There is, therefore, no danger in expos-
ing arms or hands to the beam. The only possible health hazard is in exposing the
eyes to the laser beam. Damage to the eyes can occur if the operator stares
directly into the beam.
Follow the safety precautions below to ensure operator safety:
•
Operate the BL-600 Series only according to the procedures described in
this instruction manual.
Otherwise, injury may occur due to exposure to the laser beam.
• Do not disassemble the sensor head.
Laser emission from the BL-600 series is not automatically stopped if the
sensor head is disassembled. If you disassemble the sensor head for inspection
or repair, you may be exposed to the laser beam. If the BL-600 series malfunc-
tions, contact KEYENCE immediately.
• Do not look directly at the laser beam.
Looking directly at the laser beam may result in serious eye injury.
• Protective enclosure
We recommend that you install a protective enclosure around the sensor head
to prevent any person from getting near the sensor head during operation.
• Protective goggles
We recommend that you wear protective goggles when using the BL-600
series.
• Stop laser emissions before cleaning the laser emission port.
Failure to stop the laser emission may expose eyes to the laser beam.
• Check the laser beam path.
To prevent exposure to the laser beam due to specular or diffuse reflection,
install a screen which offers the appropriate reflectance and temperature
characteristics to interrupt the reflected laser beam. Do not install the BL-600
series in such a way that the laser beam passes at eye height.
1.5 Safety Features Provided with the BL-600 Series
The BL-600 series is provided with the following safety features. Make sure these
features function correctly before operating.
• Laser emission caution LED (LASER ON LED)
During laser emission, the LASER ON LED illuminates. The LED ON status can
be checked through the laser protective glasses.
• Laser forced OFF command
Sending the laser forced OFF command (LOCK, see page 116) to the BL-600
can inhibit emission of laser beams. When working near the laser transmitter,
be sure to use the laser forced OFF command to avoid looking into the laser
beams.
When this command is selected, the bottom STABILITY LED flashes.
