Product description
3.2.6 Pallet detection
Pallet detection provides access protection in which e.g. pallets, mesh crates or trolleys
can 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.
With this type of access protection, very different pallets can be used without prior
teaching-in. No muting sensors are required, as a result it is therefore not necessary to
r
eEalign the sensors after changing the item transported.
The C4000 is mounted horizontally in the direction of transport of the objects. The beams
on the safety light curtain are aligned with the feet on a pallet or mesh crate. Then several
objects enter the protective field per pallet.
The maximum number of these floating objects depends on the protective field length
(see Tab. 2). Their maximum size of 240 mm is fixed.

As for goods detection, the first object must interrupt the first, second, third beam etc. in
succession. As soon as a further object enters the protective field, the object distance is
determined. This distance is not allowed to change as the object passes through the pro-
tective field.
