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.
