SG 1 - New High Performance Light Curtain
Telco's SpaceGuard SG1 is a technologically advanced light curtain series that presents the ultimate in design and performance, providing reliable and problem free protection of passing passengers in the most demanding elevator applications.
A complete system consists of a self-contained multi-beam infrared transmitter, SGT and a receiver, SGR. Control circuitry, electronics and optical components are all integrated into the detector profiles enabling direct connection to a door controller or lift operator without the need of a separate power supply/controller unit.
Two models are available: a high performance 40 channel model, with 194 cross scanning beams and a cost effective 20 channel model with 94 cross scanning beams, both of which are housed in a sturdy aluminium, slim line, 9.8mm profile with an active height of 1800 mm, 4 metre sensing range, 10-30 Vdc supply voltage with either a NPN or PNP transistor output. Latest technology and optical components ensure a dense sweeping curtain of cross scanning beams until the fully closed position of the elevator car doors in both static and dynamic installations.
No on site set-up or adjustments required. The SG1 series will automatically adjust to its operating conditions and surroundings during and after installation, thus achieving an optimal uniform performance by automatically compensating for misalignment and contamination during operation.
When the time-out feature is enabled, up to 4 non-adjacent channels may be ignored if obstructed for 60 seconds or more. If a time out channel resumes operation, the time-out function will automatically be cancelled 3 seconds after re-establishment, ensuring safe and reliable operation until the vandalised unit is replaced. A 24 Vdc PNP alarm output, which is activated in case of system failure or time-out, and IP 67 epoxy encapsulation, are optional.
In addition to the SG14s high EMC performance, the SG1 is even immune to a high degree of ambient light.
