The SG 2 light curtain system is designed for modernisation of elevator doors 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, solid state 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 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.

The special blanking function allows up to 10 top channels to be ignored when 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 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.
