LASER SAFETY PRECAUTIONS
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 malfunctions, contact KEYENCE immediately.
• Do not stare into the direct or specularly reflected beam.
Staring into the 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 or skin 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.
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 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.
