4 Explanation of Each Mode Measurement Modes Select one of the following measurement modes according to the measurement conditions. (1) One-side Interruption Mode 1 (First Dark Edge) (6) Pin Diameter Determination Mode (Pin Diameter) Measures the width from the edge of the beam to the end of the first Determines whether pin diameters are within a set range. dark section. (Pin number: 14 max.) (For meander detection, orientation flat positioning, etc.) (2) One-side Interruption Mode 2 (First Light Edge) Measures the width from the edge of the beam to the end of the first light section. (For gap measurement, etc.) (7) Specified Edge Measurement Mode (Edge) Measures the width of two specified edges. (3) Bar Diameter Measurement Mode (Diameter) Measures the width from the first edge to the last edge of the beam. (For measuring the diameter of bars, etc.) (8) Wire Position Detection Mode (Fine Line) Measures the position of fine lines with minimum of 0.1 dia. The measurement details are the same as that of bar position measurement mode. (For positioning of wires more than 0.1 dia.) (4) Bar Position Measurement Mode (Position) Measures the center point between the first edge and the last edge of the beam. (For position detection of bars, etc.) (9) Transparent Object Edge Detection Mode (Glass) Detects the edge of glass boards and transparent sheets. The distance between the upper edge of the beam and the edge of the transparent object is measured. (For detecting edges of transparent objects.) (5) Pin Pitch Determination Mode (Pin Pitch) Measures the pin pitch and determines if pins are centered or not. It is passed if all pin pitch are within the tolerance and rejected if not. (Pin number: 14 max.) Forced Zero Function The displayed value can be set to zero by the ZERO/ENT Key on the front panel or external input. Suitable for the discrimination of standard workpieces. Analog Output Setting Function The range of analog output can be set within the measurement width 28 mm. Enable Mode Measurement Function The processing item (i.e. maximum, minimum, maximum minus minimum, or average) can be set. The set item is calculated and output while the enable mode signal is input. Suitable for the measurement of bar movement. 4

16 FDA/ANSI Class FDA definition ANSI description Class I/1 Class IIa/2a Class II/2 Class IIIa/3a Class IIIb/3b Class IV/4 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. 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 d 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.

17 Correct Use Measurement Accuracy To improve the measurement accuracy, place the sensing object as close as possible to the receiver. Compatibility The Sensor or Controller can be used with another controller or sensor. However, the emitter and receiver are adjusted as a set. When setting up the Sensor, be sure to set the binary level before operation. Maintenance Install the Sensor in 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 little alcohol to remove the remaining dust. Do not use a scrubbing action when cleaning as scratches on the filter could result in a Sensor malfunction. Environment Do not use in strong electromagnetic fields or in an environment where the operation of the Sensor is subject to the reflection of intensive light (such as other laser beams or electric arc welding machine). The Sensor may not detect the object or the resolution may be insufficient depending on the material or shape of objects. (i.e. transparent objects, etc.) Mutual Interference Sensors can be closely mounted. Do not, however, make each laser beam closer, otherwise the Sensors may malfunction. Wiring Do not impose voltage exceeding the rated voltage, otherwise the Sensor may be broken. Do not short-circuit the load supplied with open collector output, otherwise the Sensor may be broken. Do not lay power supply cable for the together with high-voltage lines or power lines to prevent interference, damage, or malfunction. A Z49-C6 Extension Cable (2 or 8 m long) can be connected to the sensor cable or amplifier cable. 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 the same kind of shielded cable as that of the amplifier cable must be used. Use an insulated transformer for the power supply of the as shown in the illustration. Do not use an autotransformer or the may malfunction.
