Laser Product Classifications

Class

Class 1 Lasers which are safe under reasonably foreseeable conditions of opera-

tion.

Class 2 Lasers emitting visible radiation in the wavelength range from 400 nm to

700 nm. Eye protection is normally afforded by aversion responses including the blink reflex.

Class 3A Lasers which are safe for viewing with the unaided eye. For laser emitting

in the wavelength range from 400 nm to 700 nm, protection is afforded by aversion responses including the blink reflex. For other wavelengths the hazard to the unaided eye is no greater than for Class 1. Direct intrabeam viewing of Class 3A lasers with optical aides (e.g., binoculars, telescopes, microscopes) may be hazardous.

Class 3B Direct intrabeam viewing of these lasers is always hazardous. Viewing

diffuse reflections is normally safe (see note).

Class 4 Lasers which are also capable of producing hazardous diffuse reflections.

They may cause skin injuries and could also constitute a fire hazard. Their use requires extreme caution.

Note: Conditions for safe viewing of diffuse reflections for Class 3B visible lasers are: mini-

mum viewing distance of 13 cm between screen and cornea and a maximum viewing time of 10 s. Other viewing conditions require a comparison of the diffuse reflection exposure with the MPE.

Limits applicable to devices that have emissions in the ultraviolet, visible, and infrared spectra, and limits below which biological hazards have not been established.

Limits applicable to products whose visible emission does not exceed Class I limits for emission durations of 1,000 seconds or less and are not intended for viewing.

Limits applicable to products that have emissions in the visible spectrum (400 to 710 nm) for emission durations in excess of 0.25 second, providing that emissions for other durations and/or wavelengths do not exceed the Class I limits. Class II products are considered hazardous for direct long-term ocular exposure.

Limits to products that have emissions in the visible spectrum and that have beams where the total collectable radiant power does not exceed 5 milliwatts.

Limits applicable to devices that emit in the ultraviolet, visible, and infrared spectra. Class IIIb products include laser systems ranging from 5 to 500 milliwatts in the visible spectrum. Class IIIb emission levels are ocular hazards for direct exposure throughout the range of the Class, and skin hazards at the higher levels of the Class.

Exceeding the limits of Class IIIb and are a hazard for scattered reflection as well as for direct exposure.

FDA definition ANSI description

1Laser Safety

A Class 1 laser is considered to be incapable of producing damaging radiation levels during operation and maintenance and is, therefore, exempt from any control measures or other forms of surveillance.

Class 2 lasers are divided into two subclasses, 2 and 2a. A Class 2 laser emits in the visible portion of the spectrum (0.4 to

0.7 µm) and eye protection is normally afforded by the aversion response including the blink reflex.

Class 3 lasers are divided into two subclasses, 3a and 3b. A Class 3 laser may be hazardous under direct and specular reflection viewing conditions, but the diffuse reflection is usually not a hazard.

A Class 4 laser is a hazard to the eye or skin from the direct beam and sometimes from a diffuse reflection and also can be fire hazard. Class 4 lasers may also produce laser-generated air contaminants and hazardous plasma radiation.

2 Application Precautions

1. Users must operate the product according to the procedures and specifications described in this manual. (Refer to 7-1 Specifications.)

2. Do not connect or disconnect a connector between the Sensor and Controller when the power is turned ON, otherwise the Sensor may be damaged.

3. Warm up the Z4LB V2 for approximately 5 minutes after turning ON the power.

Power Supply and Wiring

1. Do not impose voltage exceeding the rated voltage, otherwise the Sensor may be damaged.

2. When supplying power to the sensor, make sure that the polarity of the power is correct, otherwise, the sensor may be damaged.

3. Do not short-circuit the load supplied with open collector output, otherwise the Sensor may be damaged.

4. The Z49-C13 Extension Cable (3 or 8 m in length) can be connected to the sensor cables or amplifier cables. The total length of the sensor cables or amplifier cables, however, must be 10 m or less. Use a shielded cable to extend the amplifier cable, in which case, a shielded cable that is the same as that of the amplifier cable must be used.

5. Do not lay a power supply cable for the Z4LB V2 together with high-voltage lines or power lines to prevent interference, damage, and malfunction.

6. Use an isolation transformer for the power supply of the Z4LB V2 as shown in the following.

3 Environment

1. Do not use the Sensor in strong electromagnetic fields or in an environment where the operation of the Sensor is subject to the reflection of intense light (such as other laser beams or electric arc-welding machine.)

2. The Sensor cannot accurately detect the following types of objects:

• Mirror-like objects

• Transparent objects

• Objects with an extremely low reflection ratio

• Objects smaller than the Sensor’s sensing spot diameter

• Largely inclined objects

3. Do not install the Z4LB V2 in locations subject to the following conditions:

• Direct vibration or shock

• Direct sunlight or heaters

• High humidity

• Dust, salt, or iron particles

• Corrosive or flammable gasses

• Water, oil, or chemical fumes or spray

• Strong magnetic or high-voltage fields

• Condensation due to rapid temperature fluctuations

• Icing due to low temperature

4 Maintenance

1. Turn OFF the power when making adjustments or removing the Sensor.

2. Install the Sensor in a clean environment and keep the filter on the front panel of the Sensor free from oil and dust. If affected by oil or dust, clean the filter as follows:

• Use a blower brush (used to clean camera lenses) to blow large dust particles from the

surface. Do not blow the dust away with your mouth.

• Use a soft cloth (for lenses) with a small amount of alcohol to remove the remaining

dust. Do not use a scrubbing action when cleaning as scratches on the filter could result in the Sensor malfunctioning.

• Do not use thinner or benzene. They will damage the optical characteristics of a filter.

3 Use the provided screwdriver and turn the gain adjuster so

that the display on the Amplifier reads 5.000 ± 0.1 V.

Turn clockwise or counterclockwise

4 Mount the emitter and the receiver in the desired positions.

Secure the receiver and tentatively secure the emitter.

5 Change the angle of the emitter upwards, downwards, left,

and right with no sensing object and secure the position of the emitter at the angle where the maximum value is displayed.

6 Turn the gain adjuster so that the display reads

5.000 ± 0.005 V.
