7 BLVT-blanking functions -typical applications
7.2 Typical applications of the several blaking patterns
The Blanking features provide the "skipping " or "blanking" of parts of the protective field. By doing this, parts of tools or machin-
ery may reach into the protective field without the reducing the function of the machine.
Die folgenden Hinweise dienen dazu, einen sichereren Einsatz des Lichtvorhangs mit Ausblendfunktion sicherzustellen.

complete protection in the entire protective field. Resolution and application same as ULVT.
This blanking pattern provides stationary blanking of up to 5 light curtain sectors of any height.
(e.g. insertion table or material feeder device))

combination of 2. and 8. Blanking of up to 5 objects which are fixed in the protective field, and ad-
ditional blanking of thin moving objects (e.g. hoses or cables) that reach into the field occasio-
nally or permanently, and, by doing so, will interrupt max. 1 beam.

blanking of an object that is moving in the protective field .

combination of 5. and 8. Blanking of an object which is moving in the protective field, and additio-
nal blanking of thin moving objects (e.g. hoses or cables) that reach into the field occasionally or
permanently, and, by doing so, will interrupt max. 1 beam.

permanently, and, by doing so, will interrupt max. 2 beams.
A flat metal sheet may reach at any position (except for the synchronization beam) into the protec-
tive field, 1 beam will be skipped once. (i.e. for blanking of thin sheet metal in press brakes).

A flat metal sheet may reach at any position (except for the synchronization beam) into the protec-
tive field, 2 beam will be skipped once. (i.e. for blanking of thicker sheet metal in press brakes).
