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.

3-1 Selecting the Measurement Unit
The measurement unit can be set to linear output voltage (V) or length (mm). In the following example, the unit is set to mm.
Display
Set the measurement unit selector to mm. The Sensor will display in millimeters.
Z4LB-S30V2 Sensor
The default setting for the measurement width of the Z4LB-CV2 Amplifier and Z4LB-CPV2 Amplifier is 10 mm. The measure­ment width of the Z4LB-S30V2 is 30 mm. Therefore, if the Z4LB­CV2 or Z4LB-CPV2 Amplifier is connected to the Z4LB-S30V2, the Amplifier cannot convert a linear output voltage range be­tween 1 and 5 V into length correctly unless the measurement width of the Amplifier is changed to 30 mm. There is no need to change the measurement width for a One-side Interruption High­precision Sensor.
Note Before using the Z4LB-S10V2 Sensor, check that the measure-
ment width is set to 10 mm. Refer to steps 1, 2, and 4.

3-2-3 Forced-zero Setting
To set the thresholds, a measured value based on a reference workpiece is first set as zero. A tolerance is then added to and subtracted from the reference value (zero) to set the results as HIGH and LOW thresholds. Forced-zero settings are possible only if the unit is set to mm.
The HIGH and LOW thresholds are kept on hold when the refer­ence workpiece is changed, which enables easy changeovers.
Thresholds are displayed between –9.999 and F.S. (see note), but the linear output voltage will not change.
Note 1 “F.S.” stands for full scale. In the case of the Z4LB-S10V2,
for example, the F.S. value is 10 mm.

4-2-6 Enabling Backup (baUp)
Determine whether the forced-zero value is to be backed up or not, i.e., to hold the value after the Sensor is turned OFF. If the backup is not enabled, the value will be lost when the Sensor is turned OFF.
Note If the backup is enabled, the forced-zero value will be written to
the internal EEPROM, which is a nonvolatile. The EEPROM has a limit on the number of writing times. Therefore, if the forced­zero value is changed frequently, disable the backup to increase the life of the memory.
