Maintenance And Inspection - Omron L User Manual

Introduction
Warming Up
After turning ON the power supply, allow the product to stand for at least 10 minutes
before use. The circuits are still unstable just after the power supply is turned ON, so
measured values may fluctuate gradually.

Maintenance and Inspection

• Always turn OFF the power supply before adjusting or connecting/disconnecting the
sensor head.
• Do not use thinner, benzene, acetone or kerosene to clean the sensor head and
amplifier units. If large dust particles adhere to the front filter of the sensor head, use
a blower brush (used to clean camera lenses) to blow them off. Do not blow the dust
away with your mouth. To remove smaller dust particles, use a soft cloth (for lenses)
with a small amount of alcohol. Take care not to wipe them off with excessive force.
Scratches on the filter may cause errors.
Sensing Object For Reflective Type Sensor Head
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.
Mutual Interference
Inserting a calculation unit between amplifier units can prevent mutual interference
between two sensor heads. However, this may not work efficiently if one sensor head is
saturated and a laser beam of the other sensor head is input. If you are interested in
installing a calculation unit in order to prevent mutual interference, carry out a test using
the actual system beforehand.
