outdoorScan3 Core I/O:
•
This example is only transferable to the outdoorScan3 Core I/O to a limited extent
as it only has a few outputs, especially if monitoring case switching is used.
If you suitably evaluate the network signals, you can use different conditions for the
start and end of the cleaning process:
•
Cleaning operation starts in case of a contamination error.
•
Cleaning operation is continued after the contamination error ends.
•
Cleaning operation ends only when the contamination warning ends.
Other possible triggers:
•
Fixed time interval
•
Time interval that depends on the weather
•
Small warning field as a trigger for efficient cleaning
Sensitivity of the warning field used as a trigger:
•
The warning field should have a finer resolution than the protective field so it
detects contamination before the protective field reports a detection.
•
The warning field should have a lower multiple sampling setting than the protec‐
tive field so it detects contamination before the protective field reports a detec‐
tion.
•
The radius r of the warning field influences the sensitivity. r < 1 m: low sensitivity,
1 m ≤ r ≤ 2 m: medium sensitivity, r > 2 m: high sensitivity.
•
If a warning field covers the entire scanning angle of 275°, it is very sensitive.
Contaminants are also detected and removed outside the area where protective
fields are located. If parts of the scanning angle are covered, e.g., by the vehicle
trim, the warning field must be appropriately adjusted.
•
If a warning field only covers the area where protective fields are also located, it is
less sensitive. This enables, for example, the consumption of compressed air to be
reduced.
