Product description
3.2.5 Goods detection
Goods detection provides access protection during which e.g. packages, or goods on a
pallet that are at least 150 mm smaller than the protective field length have access to a
system or machine. If other objects, in particular people, enter the protective field then the
C4000 shuts down its output signal switching devices.
The C4000 is mounted horizontally in the direction of transport of the objects. The beams
of the safety light curtain are aligned on the packages on the pallet.
The size of the object allowed (min. 500 mm) is configured or taught-in (see section 5.2
“Self-teach dynamic blanking for goods detection” on page 43).
A single object (e.g. a stack of pallets) must enter the protective field and in the process
interrupt the first, second, third beam etc. one after the other. The object must then leave
the protective field and in the process clear the safety light curtain beam by beam. It is
allowed to stop and restart a valid object; this action will not result in the shutdown of the
OSSDs. In bidirectional operation, the object can enter and then move back again.
