We strongly advise you to comply with the combinations given in this table for optimal operation.
Maximum range
Standard Variation*
8.5 m 6.5 to 10 m
6 m 5 to 6.5 m
3.5 m 3 to 4.5 m
2.5 m 2 to 3 m
* The maximum detection range may vary according to the atmospheric conditions.
Adjusting the setting: IMPORTANT
The detection zone can vary by 1.5 to 2.0 m
depending on the ambient temperature.
The detection zone can increase when there is a
large temperature difference between the moving
object and the background.
If the range is set to position X, it is possible that the
vehicle will be detected, depending on the ambient
temperature conditions.
In this case, set the range to position Y, which is
shorter than the ideal range but might reduce the
risk of false detection.
Perform an operating test to confirm. (a) should be
detected and not (b).
