The SG 2 series has been designed specifically for the modernisation of elevator doors and complies with the European EN 81-70 standard. The system consists of a multi beam transmitter, SGT and receiver, SGR with control circuitry, electronics and optical components all integrated into the detector profiles.
The SG 2 is available in heights of 2.00 or 2.10 m both of which create an active height of 1800 mm. There are 20 channels offering 94 cross scanning beams, whereby the blanking function will allow up to 10 top channels to be ignored when covered or masked during set up. This feature allows the active height to be reduced for applications which do not require the full 1800 mm detection height.
The housing profile is an A type, slim line design (10 x 28 mm) in natural anodised aluminium with 3 m flexible cable connection.
The SGR is supplied with a 12 – 36 V dc power supply with a 5 wire, solid state relay output and with wire selectable light or dark function.
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 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.
