SAFETY PRECAUTIONS ON LASER PRODUCT
4. Safety consideration
CAUTION
Use of controls or adjustments or the performance of procedures other than those specified herein may result in hazardous radiation exposure.
1) Class IIIb/3B laser products
WARNING
Follow the instructions mentioned in this manual. Otherwise, injury to the human body (eyes and skin) may result.
• Do not directly look at or touch the laser beam and its reflection from a mirror-like surface.
• 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. Make the laser path as short as possible and be sure to terminate the laser path with a diffusion reflector or diffusion absorber with proper reflectance and thermal characteristics so that the laser beam does not diffuse. (It is recommended that you install a protective enclo­sure.)
• Install the laser product carefully so that the laser beam is not unintentionally directed at mirror-like surfaces.
• Install the products so that the path of the laser beam is not as the same height as that of human eye.
• Wear protective eye goggles appropriate for the laser beam wavelength.
• Do not disassemble this product. Laser emission from this product is not automatically stopped when it is disassembled.
• Clean the aperture regularly. In addition, stop the emission of the laser beam when cleaning.
• MPE (Maximum Permissible Exposure): 1.66mW/cm
• NOHD (Nominal Ocular Hazard Distance): 17.2 m (LB-301) from the aperture.

2) Class IIIa/3R laser products
WARNING
Follow the instructions mentioned in this manual. Otherwise, injury to the human body (eyes and skin) may result.
• Do not directly look at or touch the laser beam and its reflection from a mirror-like surface.
• 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. Make the laser path as short as possible and be sure to terminate the laser path with a diffusion reflector or diffusion absorber with proper reflectance and thermal characteristics so that the laser beam does not diffuse.

SAFETY PRECAUTIONS ON LASER PRODUCT
3) Class 2M laser products
WARNING
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.
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.

SAFETY PRECAUTIONS ON LASER PRODUCT
For use with shield:

CONNECTIONS

LB-1001/1101/1201
CAUTION
Be sure to confirm the model number.
* GND terminals
4, 0, and B are connected internally.
■ Description of terminals
3 Earth ground terminal
5 Alarm output (NPN open-collector)
Outputs if light quantity is insufficient or excessive, or when no target is present in the operating range.
6 AUTO ZERO input
Connecting this terminal to a GND terminal (4, 0, or B) resets the analog voltage output to 0 V (12 mA for current output).
9 Analog current output
Current of 4 to 20 mA relative to full measuring range is output.
CAUTION

CAUTION
Be sure to confirm the model number.
* GND terminals
4, 0, and B are connected internally.
A Laser emission stop input
Disconnecting this terminal from a GND terminal (4, 0, or B) stops laser emission. Use this terminal in an emergency to stop laser emission. (Output will be retained at 12 V.)
C Synchronous (timing) input
Connecting this terminal to a GND terminal (4, 0, or B) permits timing input. Laser emission will stop, and the analog output value just prior to timing input will be retained. (DIP switch 2 of the controller must be set to MAIN.)
D Synchronous (timing) output
When using 2 sensors (for thickness measurement, etc.), use this terminal to prevent mutual interference. It allows 2 sensors to alternately emit a laser beam at oscillation output of 30 Hz. (Set DIP switch 2 of one controller to MAIN, and the other to SUB.)
