All safety instructions are marked with this symbol and must be observed under all circumstances! The safe operation of the entire system can only be ensured through adherence to these operating instructions and the corresponding accident prevention regulations. These operating instructions comprise part of the light barrier and must be retained at the installation site.All specifications of these operating instructions must be observed at all times . These operating instructions provide theuser with important information concerning the proper use of the ULVT/BLVT safety light barriers. ....

Start interlock Subsequent to commissioning and/or a power interruption, the start interlock prevents a "re-release". A re-release is only possibleonce the protective field has been interrupted and reactivated. Response time The time period between penetration of the protective field and the switching process. Blanking Ther Balnking features provide the temporarily "skipping" or "disabling" of selected areas of the the protective field. By doing this,parts of tools or machinery may reach into the protective field without reducing the function of the machine. (please refer topchapter 7...

Safety category 4 The ULVT safety light barriers belong to safety category 4 as per EN 945-1 and IEC 61496 / EN 61496. Devices of safety category 4 comprise self-monitoring photo-electric guards and represent the highest safety class for photo- Beam spacing The distance (gap) between the centres of the individual lenses on ULVT/BLVT... safety light barriers is called the beam distance/beam spacing. The ULVT/BLVT... safety light barriers are supplied with a lens grid of 7.5 mm, respective and 14mm. Valve or contactor control Prior to each release of the switching outputs, the contactor...

The ULVT/BLVT safety light curtains are characterized by thefollowing: > - Safety category 4 pursuant to EN 954-1 and IEC 61496 Part 1 + 2, and/or EN 61496- > 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-...

The safe distance (S) between the accident-preventing light barrier and hazardous area must be big enough to ensurethat when the protective field is penetrated, the hazardous area cannot be accessed before the hazardous movement has been ended. In addition, it must be ensured that reaching over, under or around, or walking behind the protective field is prevented by additional mechanical screening or further light barriers. To this end, please also refer to EN 999 and other effective national and international safety regulations. > 4.2.1 Vertical light barrier protection of hazardous areas...

The light transmitter (a) (Fig. 17/1) and the light receiver (b) form the light barrier (c). If the light beams are interrupted, e.g. by a hand, a pilot circuit is opened and the closing action is prevented / stopped. In the opposite example, it is not possible to avoid the ULVT light barrier from the working side, which means that additional screening is not required. In order to prevent the walking behind the protectivefield, the distance between the ULVT/BLVT safety light barrier and the machine must be _< 75 mm. > fig. 17/1 Installation without additional screening In a normal working...
