"The SG 14 light curtain system consists of a self-contained transmitter detector, SGT and receiver detector, SGR, which are to be positioned opposite of each other. The detectors are housed in a sturdy aluminium profile available in a water-resistant slim line design (12 x 30 mm) or leading edge design (38,4 x 14 mm).The SGR is supplied with a 12 – 36 V dc power supply with a 5 wire, solid state relay output, with wire selectable dynamic blanking function. The test input in the SGT may be used for either disabling or enabling the transmitting power temporarily for test purposes. The advanced automatic signal-tracking (AST) feature ensures that no onsite set up or adjustments are required. The signal level of each individual channel is adjusted automatically, which compensates for misalignment and contamination during operation. Transmitter and receiver detectors are optically synchronised.The SG 14 series features the Dynamic Sequential Blanking Function which allows the detectors to be positioned in the guide tracks of an industrial door, where the door travels directly in front of the protection area, interrupting the beams sequentially from top to bottom. The special feature ensures that the system can distinguish between the closing door and an object by ignoring the beams that are obstructed by the moving door whilst leaving the below remaining beams active to detect an object in the protection area.Both the transmitter and receiver detectors are protected against reverse polarity of power supplies, control input and output signals. The output is also protected against short circuit and inductive loads. All products include a 3-year worldwide warranty."
