3.2 Application areas
The ULVT/BLVT safety light barriers are designed to protect
hazardous areas, for cordoning off areas, and to prevent
access.
Protection of fingers, hands and body, for example in
- Presses for the processing of metal, wood, plastic, rubber,
leather and glass
- Filter presses
- Folding and bending machines
- Injection moulding machines
- Processing centres and welding presses
- Automatic placement machines
- Robots
- Palletizing machines
Using tilted mirrors, the protective field can be "wrapped
around" a hazardous area, thus ensuring protection from
several sides.
Muting operation and cycle mode are availble using safety
switching units as option. (see chapter 9).
3.1 Features
The ULVT/BLVT safety light curtains are characterized by the
following:
- Safety category 4
4 (EN ISO 13849-1:2008) and EN 61496 or IEC 61496
PL e (EN ISO 13849-1:2008)
SIL3 (EN 62061:2005)
- contactor check and restart interlock: Integrated functions
activated via DIP switch
- Direct connection of contactors / valves,
switching capacity of 0.5 A / 24 V
- beam spacings: 7,5mm, 14 mm, 100mm, 200mm, 300mm,
400mm, 500mm
- detection ranges. 7m, 24, and 60m
- 2 to 247 beams at protective field heights of 100 mm to 1900 mm
- Smallest safety distance through short response times:
4ms to 37ms, depending on construction length
- Reverse-read semi-conductor outputs with line interruption, short-
circuit and cross-circuit monitoring
-11 different blanking patterns (BLVT only). Blanking of obstacles
with reliable safety.
- cascading: for protecting a hazardous area on more than one side,
up to three light curtains may be connected in series.
