OPERATING MANUAL PSEN op4F/H-A series
7.9.2 Fixed blanking with increased tolerance
This is fixed blanking with a tolerance on only one side of the blanking zone, so the user
must select “top” or “bottom” tolerance.
This function is particularly helpful with conveyor belts (which use fixed blanking) with goods
transported along them (dimensions within the tolerance).
Only fixed blanking zones can be set on the tolerance side. On the other side it’s possible to
set fixed as well as floating blanking zones with total surveillance.
Only one zone can be set with fixed blanking and increased tolerance.
This function can only be set via ACM.
Please note that the actual resolution changes when using this
function. Ensure that the minimum distance has to be recalculated
and that the installation of the light curtain must
7.9.3 Floating blanking with total surveillance
Floating blanking with total surveillance enables the object to move freely within the light
curtain’s protected field. The blanked beams must be occupied, which means that the object
must stay within the light curtain’s protected field to remain in normal operating mode.
This function can only be set via ACM.
7.9.4 Floating blanking with partial surveillance
Floating blanking with partial surveillance ensures that the object moves freely within the light
curtain’s protected field, although only a certain area in the light curtain is permitted and the
hidden beams are adjacent and must not exceed the configured number.
This function can only be set via ACM.
The diagram below illustrates various blanking configurations.
