Light curtains offer increased protection

16 September 2009

Schneider Electric has launched two type 4 light curtains, the XUSLB and the XUSLD. Light curtains work by shielding the equipment with light beams. If one of these beams is broken, any dangerous movement of machine parts stops, protecting personnel while still allowing access to the machines should maintenance need to be carried out.

The XUSLB provides basic light curtain functions, with the XUSLD including additional standard features such as built-in muting, programmable blanking and cascading of up to four segments. Both new light curtains offer flexible installation possibilities, due to their ability to share components, cables and accessories.
The two models can be programmed and diagnosed using a handheld programmer. This allows for much quicker and easier configuration and maintenance, without the need for a PC. The sensitivity of the light beams can be adjusted.
