The safety laser scanner with a network connection automatically triggers different
cleaning operations depending on the degree of contamination. The cleaning operation
can also be triggered manually.
The following cleaning operations are available:
•
Two-stage preventive cleaning when a warning field reports a detection or
the safety laser scanner reports a contamination warning. Preventive cleaning
removes water droplets early so that the safety laser scanner does not switch to
the OFF state.
•
Two-stage efficient cleaning when the safety laser scanner reports a contamina‐
tion error. Efficient cleaning removes water droplets when the safety laser scanner
has already switched to the OFF state.
•
System cleaning when manually requested using a pushbutton. System cleaning
removes condensate from the compressed air lines and airWiper, e.g., after a long
downtime.
