Type 4 miniature light curtain, 14 mm/0.55 in resolution Designed for the protection of operators work stations TYPICAL APPLICATIONS * Paper-cutting machines * Pick-and-place robots * Light electronic assemblying machines * Textile machines * Leather presses * Matching centres HANNOVER SACHSEN-ANHALT Approved as Type 4 per pr EN 50100 - 1/2 The FF-LS14 equipment is an ultra-compact infrared multibeam device designed to protect operators working on dangerous machines. The FF-LS14 equipment features are ideal for the protection of work stations where space is critical such as paper-cutting machines or pickand-place robots. Thanks to a small resolution, it will spring into action even if a finger gets too close: any intrusion will lead to the immediate stoppage of the moving part of the machine. Each sensing unit is made up of a row of emitting circuits alternating with receiving circuits. These circuits are housed in an extremely small aluminium extruded profile: the cross section is only 23 mm x 35 mm / 0.90 in x 1.38 in, the smallest available on the market in its class. These ultra-compact dimensions, backed by in-line connectors, allow the FF-LS14 to be mounted on small machines or in other applications where light curtains were previously too large. Its small resolution - the smallest on the market - allows the closest installation to the dangerous area, thanks to no additional safety distance in the safety distance calculation formula (EN 999). The permanent self-checking electronic process is based on a microprocessor technology and meets the requirements of the IEC/EN 61496 - parts 1 & 2 European standards for Type 4 electrosensitive protective equipment. It has been granted the EC type examination certificate by the TUV. The equipment consists of a pair of identical length sensing units, a separate control unit and a pair of RS-485 connection cables. It is supplied with mounting brackets, a test rod and cable glands for the terminal strip connections. The two sensors are matched to each other by individual coding to reduce risk of cross talk with other light curtains and to improve immunity to welding splashes. The control unit supplies the sensing units, controls the correct operation of the scanning circuits and transmits the resulting commands to the machine control circuitry through its two relay outputs. The equipment can operate according to two different modes selected with an internal selector: the automatic mode or the start & restart interlock mode. In addition, the control unit is featured with a test input to trigger the output relays switching and thus check the correct operation of the final switching devices whenever needed. In case of failure, the control unit provides an acoustic signal and 6 different optical signals to ease failure diagnostic.
