• FLOATING blanking with total surveillance
Floating objects can move up and down, interrupting several beams in the process. These
objects can overlap or change positions.
The object must be within the protected field at all times and interrupt the number of
configured beams with a fixed tolerance of one beam. This is necessary so that a moving
object always interrupts a different number of beams.
• FLO
ATING blanking with partial surveillance
Fl
oating objects can move up and down, interrupting several beams in the process.
These objects can also
− leave the protected field or
− interrupt a lower number of beams than that configured.
O
nly fixed blanking can be configured around this zone. In these fixed blanking zones,
floating objects can overlap and even change position without causing the OSSDs to
switch.
