Configuration of blanking
5.4.1 Object size monitoring
In addition you can configure object size monitoring. On the entry of objects into the pro-
tective field, first the validity of the object is checked based in the minimum and maximum
object size configured . The actual size is then “frozen” and monitored during the entire
time it passes through the field . It is also monitored that the distances between the ob-
jects do not change .
The C4000 switches to red, if …
more or less objects than configured pass the protective field.
the object is below the minimum object size or above the maximum object size.
the frozen size changes by more than the tolerance allowed (see section 12.3.1 on
page 101).
the distances between the objects change by more than the tolerances (see
section 12.3.1 on page 101).
an object enters the protective field other than at the start.
an object leaves the protective field other than at the end.
the object has gaps or the gaps are larger than the gap suppression configured.
the protective field of the safety light curtain is interrupted completely.
the first and last beam of the protective field are interrupted on switching on.
Minimum distance between two objects with object pattern recognition
For it to be possible to detect individual objects, these must maintain a minimum distance
of 20 mm.
