Please observe the following precautions to prevent failure to operate, malfunctions, or undesirable effects on
product performance.
1. Installation Site
Do not install the product in locations subjected to the following conditions:
• Ambient 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 ultraviolet shine)
• Direct sunlight or near heaters
• Water, oil, or chemical fumes, spray or mist atmospherics
• Strong magnetic or electric field
2. Power Supply and Wiring
• When using a commercially available switching regulator, make sure that the FG terminal is grounded.
• If surge currents are present in the power lines, connect surge absorbers that suit the operating environment.
• Before turning ON the power after the product is connected, make sure that the power supply voltage is
correct, there are no incorrect connections (e.g. load short-circuit) and the load current is appropriate.
Incorrect wiring may result in breakdown of the product.
• Use the specified voltage. If voltage exceeding the rating or AC voltage is applied, circuit parts may be burnt
or rupture.
• Use the Extension Fiber Cable (ZW-XF@@R) for extending the fiber cable between the Sensor extension
fiber cable, five total lengths, 2, 5, 10, 20 or 30 m, are available.
• Handling fiber cables
Use them in compliance with the following. This may result in damage to the fiber cable.
-Fiber cable bend radiuses must be at least 20 mm.
- Do not let bending cause stress at the root section of a fiber connector.
- Do not yank hard on a fiber cable.
- Do not step on a fiber cable or place anything heavy on it.
- Do not apply any twisting stress to the fiber cable.
• Be sure to use a Sensor Head and Calibration ROM with the same serial number. A pair with different serial
numbers cannot operate normally.
• Use the configuration software with the combination specified in this manual, or the system may operate
faultily.
• Do not shut down the power supply when saving any data into the memory built in the Sensor Controller, or
the data may be corrupted.
• While a fiber cable is disconnected, be sure to attach the included protective cap on both the Sensor
Controller side and the fiber cable side. Leaving the fiber cable with the protective cap not attached, the
optical fiber may fail due to any adhered foreign matter.
3. Warming Up
After turning ON the power supply, allow the product to stand for at least 30 minutes before use. The circuits
are still unstable immediately after the power supply is turned ON, so measured values may fluctuate gradually.
Precautions for Correct Use

ZW User's Manual 7
4. Maintenance and Inspection
Do not use thinner, benzene, acetone or kerosene to clean the Sensor Head, fiber cable and Sensor Controller.
If large dust particles adhere to the emitter/receiver of the Sensor Head or Sensor Controller, use a blower
brush (used to clean camera lenses) to blow them off. Do not blow the dust particles with your mouth.
To remove smaller dust particles, dirt, oil, and fat, wipe gently with a soft cloth (for cleaning lenses). Do not use
excessive force to wipe off dust particles. Scratches on the emitter/receiver may cause false operations or
measuring errors.
For details on the method for cleaning the ends of fiber cables, refer to "Connecting Fiber Cable" (p.38).
Clean the ventilation port periodically to prevent any build up of dirt and dust. If the ventilation port is blocked,
heat builds up inside and can cause breakdown.
5. Sensing Objects
The product sometimes cannot accurately measure the following types of objects: Transparent objects, objects
with an extremely low reflection factor, objects smaller than the spot diameter, objects with a large curvature,
excessively inclined objects, target objects with a thin film on the surface etc.
6. Effect caused by peripheral lights
Do not install the Sensor Head in a place where strong light hits the laser emitter/receiver section of the Sensor
Head. Also, if an object has a shiny surface, the light from the lighting will be reflected and a malfunction may
occur. In such a case, prevent reflection by, for example, covering the light to stop reflection.
Basic precautions for installation p.30
7. Influence by Air Turbulences
Slow air turbulences around the Sensor Head may disperse measured values.
To avoid these possible air turbulences, wrap the Sensor Head with an appropriate cover.
8. Operations Outside Measurement Range
This sensor is highly sensitive, it may operate incorrectly outside the measurement range (too close in). In such
a case, the problem can be solved by reducing the exposure time.
