12. Blanking
13. Software configuration
The blanking function is used when an object detected in a defined part of the detection zone must not cause an OFF-
state of the light curtains outputs.
Blanked beams are monitored so that the absence or a change in the size or location of the object causes the light
curtain’s outputs to go to the OFF-state.
Fixed blanking is when the object must remain in a fixed position, with a given tolerance.
Floating blanking is when the object can move along the detection zone.
Depending on the configuration of the light curtain, in floating blanking the object can also leave the detection zone or not.
Reduced resolution is a particular kind of floating blanking, with light curtain outputs going OFF-state only when a pre-
defined number of beams adjacent are interrupted, in any position along the light curtain. When reduced resolution is
active, more than one small object can interrupt the light curtain beams without its output going OFF.
Blanking can affect the detection capability of the light curtain and can result in a recalculation of the minimum safety distance.
Setting DIP-Switch or through wiring, it is possible to set typical parameters like manual or auto reset, EDM enable or
disable, muting type selection, as well as auto-teach blanking function.
A software configurator (
Graphic User Interface, GUI
) is required for more advanced functionality, such as setting the
muting timeout with 1-second steps, or designing complex patterns for floating or fixed blanking.
