FUNCTIONS

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.
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 con-
figured 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.
