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.34).
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.26
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.
