7.9.2 Fixed Blanking with increased tolerance
This is a fixed blanking with the tolerance only on one side of the blanking zone, so the user
has to choose a “tolerance top” or a “tolerance bottom”.
This function is useful for conveyors (that use fixed blanking) with goods moving on them
(with a dimension within the tolerance).
Only fixed blanking zones can be set on the side of the tolerance; on the other side fixed
blanking or floating blanking with total surveillance zones are allowed.
Only one zone can be set as fixed blanking with increased tolerance.
This function can be set only by means of ACM.
Note: Tolerance affects effective ESPE resolution.
7.9.3 Floating Blanking with total surveillance
Floating Blanking with total surveillance allows the object to move freely inside the light
curtain’s controlled area. The blanked beams must be occupied and therefore the object has
to be inside the controlled area of the light curtain to remain in normal operation state.
This function can be set only by means of ACM.
7.9.4 Floating Blanking with partial surveillance
Floating Blanking with partial surveillance allows the object to move freely inside the light
curtain’s controlled area, occupying till a given number of beams, at the condition that the
occupied beams are adjacent and that their number is not higher than the configured one.
In this mode, the object may be removed from the controlled area.
This function can be set only by means of ACM.
In the figure below the different blanking configurations can be seen.
