Environment
1. Do not use the Sensor in strong electromagnetic fields or in an environment where the
operation of the Sensor is subject to the reflection of intense light (such as other laser
beams or electric arc-welding machine.)
2. The Sensor cannot accurately detect the following types of objects:
•
Mirror-like objects
•
Transparent objects
•
Objects with an extremely low reflection ratio
•
Objects smaller than the Sensor’s sensing spot diameter
•
Largely inclined objects
3. Do not install the Z4LB V2 in locations subject to the following conditions:
•
Direct vibration or shock
•
Direct sunlight or heaters
•
High humidity
•
Dust, salt, or iron particles
•
Corrosive or flammable gasses
•
Water, oil, or chemical fumes or spray
•
Strong magnetic or high-voltage fields
•
Condensation due to rapid temperature fluctuations
•
Icing due to low temperature

Maintenance
1. Turn OFF the power when making adjustments or removing the Sensor.
2. Install the Sensor in a clean environment and keep the filter on the front panel of the
Sensor free from oil and dust. If affected by oil or dust, clean the filter as follows:
•
Use a blower brush (used to clean camera lenses) to blow large dust particles from the
surface. Do not blow the dust away with your mouth.
•
Use a soft cloth (for lenses) with a small amount of alcohol to remove the remaining
dust. Do not use a scrubbing action when cleaning as scratches on the filter could re-
sult in the Sensor malfunctioning.
•
Do not use thinner or benzene. They will damage the optical characteristics of a filter.
