Description

0-4 metre sensing range 94 cross scanning beams Active height of 1800 mm Detector length 2000 mm or 2100 mm Flexible cable connection Automatic sensitivity adjustment Slim line (10x28 mm) detector housing Power, output and signal status indicators 12 – 36 V dc supply voltage Blanking function of up to 10 channels 5 wire, solid state relay manufacturer output Test input Light/dark function via wire connection Complies with standard EN 81-70 The SG 2 light curtain system is designed for modernisation of elevatordoors and 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 an aluminium profile available in a slim line design (10 x 28 mm).The SGR is supplied with a 12 – 36 V dc power supply with a 5 wire, solidstate relay output and with wire selectable light or dark function. The test input in the SGT may be used for either disabling or enabling the transmitting power temporarily for test purposes.The detectors are available with time-out function which allows up to 2 non-adjacent channels to be ignored if permanently obstructed for 10 seconds or more. The advanced automatic signal-tracking (AST) feature ensures that noonsite set up or adjustments are required. The signal level of each individual channel is adjusted automatically compensating for misalignment and contamination during operation. Transmitter and receiver detectors are optically synchronised. The system can be used both in static and dynamic applications.The special blanking function allows up to 10 top channels to be ignoredwhen covered/masked during set up. This feature allows the active height to be reduced for applications which do not allow the full detection height.Both the transmitter and receiver detectors are protected against reversepolarity of power supplies manufacturer, control input and output signals. The output is also protected against short circuit and inductive loads. Technical Data
