Configuration of blanking
5.2 Self-teach dynamic blanking for goods detection
The beams on the C4000 are aligned with the freight on the pallet for goods detection.
Using this function, e.g., pallets with packages can be blanked that as a result then have
access to a system or machine.
Valid object in the protective field Person in the protective field
If other objects, in particular people, enter the protective field then the C4000 shuts down
its output signal switching devices.
If you use a C4000 with a protective field length <750 mm, you must take suitable mea-
sures to prevent stepping over the protective field (see section 6.1 “Additional measures
to prevent bypassing of the protection” on page 58).
Prevent people entering the hazardous area beside the object!
During entry, the item transported must block the access to the hazardous area.
You can configure the goods detection function in the CDS on the C4000 (receiver).
For goods detection you have to configure:
a minimum object size. This is approx. 500 mm
5)
.
a maximum object size. This is approx. 150 mm less than the protective field
5)
.
The object size can also be taught-in (see section 5.2.2 “Teach-in of individual
objects”on page 45).
The C4000 switches to red, if …
more than one object enters the protective field.
the object is below the minimum object size or above the maximum object size.
an object enters the protective field other than at the start.
an object leaves the protective field other than at the end.
the object enters the protective field in the wrong direction with direction detection
configured.
the object has gaps or these gaps are larger than the object gap suppression
configured.
the protective field of the safety light curtain is interrupted completely.
the first and last beam of the protective field are interrupted on switching on.
Object size that will result in safe shutdown
The object size that results in safe shutdown is dependent on the size configured, the
reduced resolution if configured, and the resolution of the C4000.
5)
Depending on the resolution of the C4000.
