Calculation settings that eliminate the need for a digital panel meter Patent pending A calculation unit can be inserted between two amplifiers to display the calculation results of two sensor units on one of the amplifiers. Settings are accomplished by simply entering the necessary parameters in one of the amplifiers. Includes a sensor life monitor. The laser diode (LD) life is detected automatically and the operator alerted. When LD deterioration is detected, the sub-display alerts you. This gives you time to take action before the LD dies.

18 -LD###/-LDV# Classification of reflective-type sensor heads Classification of reflective-type sensor head of -LT### Laser-related labeling The warning label at right is attached to the side of the sensor head. Class Class WARNING LASER RADIATION DO NOT STARE INTO BEAM CAUTION- LASER RADIATION WHEN OPEN MAXIMUM OUTPUT: mw PULSE DURATION: WAVELENGTH: 6 nm CLASS LASER PRODUCT JIS C Appendix I 998 Handing Instructions The -LD###/-LDV# emits visible laser light. Do not look directly at the light. Terminate the light path of the laser beam before use. If a reflective mirror surface is in the light path, ensure that the reflected light path is enclosed in the beam. In cases where the light path must be open, ensure that it is kept away from eye-height. (U.S.A.) Exports of products equipped with this device to the U.S.A. are governed by the laser standards of the Food and Drug Administration of the U.S.A. The Laser Series is classified as Class I and Class II device according to FDA ( CFR.). Please inquire for detailed information on exporting to the U.S.A.. (Countries other than the U.S.A.) -LD##/-LDV@ reflective-type (displacement) sensor head: In countries other than Japan and the U.S.A., replace the warning label with the provided English label. For the -LT### transmissive-type (displacement) sensor head, the warning label already includes English, thus replacement is not necessary. With respect to exports to Europe, a different standard exists, Europe EN68. Correct Use Design Object Some object materials and forms may not permit measurement, or may reduce the accuracy of measurement (transparent materials or materials with an extremely low reflectance; steeply inclined objects, etc.). Power Supply and Wiring Do not connect or disconnect the connector while powered. Damage may result. Allow the system to warm up for about minutes after turning on the power. Upon completed wiring, verify that the power source is wired correctly, that there are no incorrect connections that will cause load shorts, and that the load current is appropriate before turning on the power. Incorrect wiring may result in damage. When extending the cable, ensure that the overall length does not exceed m from both the sensor head and the amplifier unit. If you need to extend the cable from the sensor head, use the optional extension cable (-XC#A). For wiring from the amplifier unit, use the same type of shielded cable. If the power line is subject to surges, connect a surge protector. If you are using a computing unit, connect the linear GND terminals of the amplifier units. Compatibility The sensor head and amplifier unit are compatible. A sensor head purchased later can also be used. Mutual Interference This sensor head allows the amplifier units to be used in conjunction by connecting a computing unit (-CAL) between the amplifier units. Cleaning Do not use thinner, benzene, acetone, or kerosene, or similar chemicals. B-8 Displacement sensors / Width-measuring Sensors

Forced-zero indicator (displayed as the lowest decimal place) Functions Lights when laser beams are emitted. The Sensor and Amplifier indicators light at the same time. Displays either linear output voltage (V) or length (mm) according to the measurement unit selector switch setting. If the measurement unit is set to length (mm), set the measurement width to be used. The default setting is mm. The amount of incident light or light interruption can be selected using the light/dark mode selector switch. Lights when HIGH/PASS discrimination output turns ON. Lights when LOW/NG discrimination output turns ON. Lights when the forced-zero settings are enabled in RUN mode. Light mode Light mode Linear output (with light/dark mode selection function) Outputs voltage ( to VDC) proportional to the amount of incident light or light interruption. The light/dark mode selector switch is used to select either light or dark mode.

When LD OFF is input, the laser stops emitting light. appears in the display, and the linear output, HIGH/LOW decision indicator lamp and output retain their previous states. The display (LD ON indicator lamp) and all outputs retain their previous values. Displays the measured value as zero when the unit is set to length (mm).the value is set if forced-zero input is ON for. to.8 s and cleared if it is ON for s or more.to set forced-zero or clear forced-zero, press and hold down the SET Key for s while in RUN mode. Forced actuation of OFF HIGH/PASS or LOW/NG discrimination output if this input turns ON during "normal" measurement. Controls sampling timing if this input turns ON during "hold" measurement. The default setting is "normal." ² There are two banks, for each of which a threshold value can be set. If the bank selection input is enabled, the thresholds to be used for evaluation can be switched. The default setting is "disabled." F.S. Amount of incident light (mm) F.S.

The thresholds are set to desired values by using the Right Key, Up Key, and SET Key. The thresholds are set to desired values by teaching. The HIGH threshold output turns ON when the HIGH threshold is equal to or below a measured value. The LOW threshold output turns ON when the LOW threshold is equal to or above a measured value. Holds the display and output values. Select from six hold methods according to the application (peak hold, bottom hold, sample hold, peak-to-peak hold, self peak hold, and self bottom hold). The default setting is "normal." Specifies whether to back up the forced-zero set value. If the value is to be retained after the Sensor is turned OFF, always enable the backup. The default setting is "enabled". Response time switching function The resolution changes with the response time. Select the required response time, taking the resolution into consideration.

The laser beam emitted from the laser has high power density and its entry in your eyes may cause blindness. Laser safety Safety measures are required for laser devices both in Japan and abroad. Brief explanations follow of requirements for use in Japan and requirements for export to other countries after assembly in Japan. For details, see the corresponding standards.
