irection detection
The C4000 can also monitor the direction of object movement.
You can configure the direction detection function in the CDS on the C4000 (receiver).
For this purpose, the direction of entry into the beam path can be configured:
object entry only adjacent to display
object entry only remote from display
from both directions
In addition to the shutdown criteria in 5.1, 5.3 and 5.4 the following applies:
If one of the “object entry only adjacent to display” or “object entry only remote from
display” options is selected, the C4000 switches to red if an object moves in the wrong
direction.
The tolerance of the direction detection is 150 mm. As a result the object can also move
unevenly through the protective field. If an object enters in the wrong direction, the C4000
only switches to red once the object has entered 150 mm into the protective field.
5.6 Fixed blanking
The C4000 Fusion safety light curtain is capable of fixed-blanking up to five areas in the
protective field, e.g. to allow continued operation in spite of an obstruction such as a sup-
port arm placed permanently in the light path.
The blanked area will no longer be part of the protective field. Objects to be blanked out
must therefore be permanently located inside the blanked area (). As soon as the object
is removed from the beam path, the safety light curtain will interrupt the dangerous move-
ment (). Protection is otherwise no longer guaranteed.
The size and the position of blanked areas are defined simply by the operator by placing
objects of appropriate size in the required positions in the protective field and then teach-
ing-in these areas with the aid of a key-operated pushbutton for teach-in. This is, e.g.,
useful during a tool change.
