WARNING

;9-%-BTFS8BSOJOH-BCFM

;9-%-&YQMBOBUPSZ-BCFM

PRECAUTIONS FOR SAFE USE
The following precautions must be observed, since they are essential to ensure safety in operation. Installation Environment ·Do not use the Sensor in locations subject to explosive or flammable gases. · To ensure safety in operation and maintenance, do not install the Sensor near high-voltage equipment or power devices.
Power Supply and Wiring · Do not impose voltage exceeding the rated voltage: 10 to 30 VDC, including 10% ripple (p-p). · When supplying power to the Sensor, make sure that the polarity of the power is correct, and do
not connect to an AC power supply. · Do not short-circuit the load for the open collector output. Short-circuiting the load may cause
fire or damage on the Sensor. · Connect the load correctly. Short-circuiting the load may cause fire or damage on the Sensor. · Keep the load within the rated range. Overloading may result in fire or damage on the Sensor. · Wire the product cable separately from high-voltage or power lines. Placing them in the same
wiring or the same duct may cause induction, resulting in the product malfunction or damage. · Always turn off the power of the Sensor before connecting or disconnecting the cable or
connector. · Do not use the Sensor for the safety circuits in nuclear power or life-critical applications. · Implement safety measures e.g. fail-safe circuits. Installation · Make sure that all installation screws must be tighten securely.
Tightening torque: M3, 0.5N·m (ZX1-LD50/ZX1-LD100) M4, 1.2N·m (ZX1-LD300/ZX1-LD600)
Others · Do not attempt to disassemble, deform by pressure, incinerate, repair, or modify this product. · When disposing of the product, treat as industrial waste. · If you notice an abnormal condition such as a strange odor, extreme heating of the unit, or
smoke, immediately stop using the product, turn off the power, and consult your dealer.

Do not expose your eyes to the laser radiation either directly (i.e., after reflection from a mirror or shiny surface). Loss of sight may possibly occur in case of the exposure to laser high power density. Caution – Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure
Do not disassemble the product. Doing so may cause the laser beam to leak, resulting in the danger of visual impairment.

SAFETY PRECAUTIONS FOR USING LASER EQUIPMENT

Laser safety measures for laser devices are stipulated both in Japan and overseas. Here, four cases are described. (1) Usage in Japan
The JIS C6802:2014 standard stipulates the safety precautions that users must take according to the class of the laser product. The ZX1-LD is classified into class 2 defined by this standard. The ZX1-LDL is classified into class 1 defined by this standard. Labeling on Laser Use

The ZX1-LD has the following WARNING label or explanatory label on the side of the sensors.

;9-%-BTFS8BSOJOH-BCFM

;9-%-&YQMBOBUPSZ-BCFM

(2) USA
This product is subjected to the U.S. FDA (Food and
Drug Administration) laser regulations. The ZX1-LD and ZX1-LDL is already reported to CDRH (Center for Devices and Radiological Health).
Accession Number: (ZX1-LD :1210041-000) (ZX1-LDL :1210041-001) When using a device equipped with the The ZX1-LD
and The ZX1-LD L in the U.S., attach an FDA certification label on the sensor at the correct location as
indicated,and replace the warning label or explanatory
label with corresponding English Label(FDA). The ZX1-LD is classified into Class 2 by the IEC
60825-1:2007 standard according to the regulations of
Laser Notice No.50 of the FDA standard. The ZX1-LDL is classified into Class 1 by the IEC
60825-1:2007 standard according to the regulations of
Laser Notice No.50 of the FDA standard.

PRECAUTIONS FOR CORRECT USE
Installation Location Do not install the product in locations subjected to the following conditions: · Surrounding air temperature outside the rating · Rapid temperature fluctuations (causing condensation) · Relative humidity outside the range of 35 to 85% · Presence of corrosive or flammable gases · Presence of dust, salt, or iron particles · Direct vibration or shock · Reflection of intense light (such as other laser beams, electric arc-welding machines, or
ultra-violet light) · Direct sunlight or near heaters · Water, oil, or chemical fumes or spray, or mist atmospheres · Strong magnetic or electric field · In the water, rain, or outdoors Power Supply and Wiring · Do not supply the power to the Sensor before checking the I/O wiring. · Ground the FG terminal when using a commercially-available switching regulator. · If the power supply line is subject to surges, connect a surge absorber that meets the conditions
of the operating environment. · Do not turn ON the power after wiring before making sure that the power supply is connected
correctly; there are no faulty connections, e.g. load short-circuits; the load current is correct. Incorrect wiring may result in failure. · Use a ZX0-XCR Extension Cable (sold separately) to extend the Sensor’s cable. Use only one cable. Do not extend the cable for the Sensor to a length exceeding 20 m. · The display and indicators turn ON after approx. 2.5 seconds after the power is turned ON. · The sensor is certificated by the UL standard on the assumption of the following installation conditions. It is based on the assumption of usage in “Class 2 circuit”. Please use it with “Class 2 power supply”
in the United States or Canada. The current rating of overcorrect protection is 0.8A max. It is certificated as open type. The sensor shall be installed within an enclosure. Rating of the cable is 30V. Please use it as internal cable wiring only in the end products equipment. Warming Up · After turning ON the power, allow the Sensor to warm up for approx. 30 minutes prior to use. The circuitry is not stable immediately after turning the power ON, and the values gradually change until the Sensor is completely warmed up. When using LD-OFF input for a long period of time, perform warmng up for more than 30 minutes after cancelling LD-OFF. Maintenance and Inspection · Always turn OFF the power of the Sensor before connecting or disconnecting the cable or for making adjustment. · Do not use thinner, alcohol, benzene, acetone, or kerosene to clean the Sensor. · If considerable foreign matter or dust collects on the glass surface of the front of Sensor, use a blower brush (for camera lenses) to blow off the foreign matter. Avoid blowing it off with your breath. For a small amount of foreign matter or dust, gently wipe with a soft cloth. Do not wipe hard. The damaged glass surface may result in detection errors. Sensing Object The product cannot accurately measure the following types of objects: Transparent objects, objects with an extremely low reflective sensor ratio, objects smaller than the spot diameter, objects with a large curvature, excessively inclined objects, etc.

changing the tuning type.

Refer to ” 2.Tuning Type, Detailed Settings”

· When setting the background suppression function to ON and performing tuning, the measurement value and sensitivity level can be limited according to the sensitivity. Use it when abnormal distance is detected due to diffuse reflection caused by surrounding walls, etc.

Refer to ” 5. Background suppression function, Detailed Settings”

· When performing tuning, threshold values are recorded in EEPROM (non-volatile

memory) in the sensor. The writing life of EEPROM is 100,000 times. Be careful of

writing life when performing measurement-by-measurement tuning.

2-5 Fine Adjustment of Hysteresis Width
Hysteresis Width Setting A minute step can be judged by adjusting the hysteresis width according to the workpiece. However, note that the judgment output varies if lowering the hysteresis width while the displacement value is varying due to moving workpiece or low reflection light intensity.
What is Hysteresis Width? A point in which a judgment output turns from OFF to ON is called an operating point, and a point in which a judgment output turns from ON to OFF is called a return point. On this sensor, threshold means operating point, and a distance to the return point can be set based on the hysteresis width.
Note that the direction where the hysteresis width is set for the threshold differs depending on ON/OFF of the area output.

Tuning mode without Workpiece (Area Output is OFF)
Used to judge the presence/absence of a workpiece using the pre-determined background (reference surface) as the reference. Unlike 1-point tuning, this method focuses on the detection of the absence of workpiece. Insufficient light level or outside-range errors caused by complicated workpiece appearance are judged as “the presence of the workpiece”.
