PRECAUTIONS FOR CORRECT USE
Observe the following to prevent failure, malfunctioning, and adverse effects on performance and the device.
1.Installation site
Do not install in the following locations:
• Locations where the ambient temperature exceeds the rated temperature range.
• Locations subject to sudden temperature changes (where condensation will form).
• Locations where the relative humidity is below or above 35 to 85% RH.
• Locations where there are corrosive or flammable gases.
• Locations where there is dust, salt, or iron powder.
• Locations where the device will be subject to direct vibration or shock.
• Locations where there is strong scattered light (laser light, arc welding light, ultraviolet light, etc.)
• Locations exposed to direct sunlight or next to a heater.
• Locations where there is splashing or spraying of water, oil, or chemicals.
• Locations where there is a strong electrical or magnetic field.
2.Power and cable connections
• When using a commercially available switching regulator, make sure that the Frame ground terminal is grounded.
• Wire without placing load on the cables/connectors.
• If there are surges on your power line, connect a surge absorber as appropriate for your conditions of use.
• Use the product with the specified voltage. Applying a voltage or AC voltage that exceed the rating may result in burning
or explosion of circuit components.
• To extend the fiber cable between the Sensor Head and Controller, an optional extension fiber cable (ZW-XF70□□R)
must be used. Only one extension fiber cable can be connected.
• Use the Sensor Head and Calibration ROM of the same serial number. Operation will fail if those with different serial
numbers are used.
• Use the dedicated Setup Software. Using the other software may result in malfunction of the product.
• Do not turn off the power supply while saving data into the Controller built-in memory. Doing so may damage the data.
• When the fiber cable is not connected, attach the provided protective caps to the fiber cable connector. Leaving the
product without the protective caps may result in malfunction caused by adhesion of a foreign material.
3.Warming Up
After turning on the power supply, allow the Controller to stand for at least 30 minutes before use. The internal temperature
of the controller are unstable immediately after the power supply is turned on and attempting measurement may result in
inconsistent measurement values.
4.Maintenance
• Do not use thinner, benzene, acetone or kerosene to clean the Sensor Head, fiber cable or Controller. If considerable foreign
matter or dust collects on the Sensor Head or receiver/emitter of the Controller, 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. If the receiver/emitter is damaged, malfunction or measurement error may result.
• Do not touch the end face of the fiber cable of the sensor head. Otherwise, performance deterioration might occur. If the end
face touches anything or becomes unclean, wipe off the dirt with option product ZW-XCL, the commercially available
dedicated fiber cleaner, or a dry soft cloth. Do not use cloth soaked in alcohol. Otherwise, dirt might adhere again.
• To clean the fiber connector of the controller, use option product ZW-XCL or the commercially available dedicated fiber
cleaner.
• If inserting/extracting the sensor head frequently, use of the repeatedly usable commercially available dedicated fiber cleaner is
recommended. For the recommended fiber cleaner, refer to the operation manual of the sensor head (ZW-S70□□).
• Clean the vent hole periodically so as not to be clogged with dust or particulate. If the vent hole is clogged, heat is not
dissipated from inside, leading a failure.
5.Sensing Object For Sensor Head
Depending on the material/shape of the object, the object cannot be measured or can be measured but accuracy is poor:
Transparent objects, objects with a low reflective sensor ratio, objects smaller than the spot diameter, objects with a large
curvature, excessively inclined objects, objects with thin film on the surface, etc.
6.Effects of surrounding lightings
Avoid installing the product at a location where the emitter/receiver of the Sensor Head is exposed to strong lighting. If the
objects has reflective surface, malfunction of the product may occur due to light reflection. Prevent it by covering the
lighting.
7. Influence of air current
Measured values may vary due to slow air current around the Sensor Head. In such case, put a cover around the Sensor
Head.
8.Operation beyond the measurement range
As this sensor is sensitive, malfunction may occur beyond the measurement range (near side). In such case, shortening the
exposure time may solve the problem.
9.Service life of writing to sensor controller built-in EEPROM
When the zero resetting memory is preset ON, data are written in the EEPROM (non-volatile memory) in the sensor
controller every time the memory is reset to zero. The life of this EEPROM as a writable memory is approximately one
million times. So, if using the memory with setting it ON, be careful with the life of the writable memory.
