Pre-assembled module chains of the D version (rev.) – available as a 3-module or 7-module chain, for the transmitter or receiver side. The cost-effective chains simplify stockkeeping and installation: they are supplied as a ready-made unit and connected to the TLCU22-04 central unit via adapter cables.
3-module and 7-module chains can be combined to build automatic restart systems with up to 99 light barriers per escalator side. Each chain is terminated by an active end module.
Automatic restart systems (WBS) are used on escalators and moving walks in public and commercial passenger transport and automatically release the unit again after an emergency stop as soon as nobody is on it any more. The D version is designed for escalators made by Kone and Otis.
The light curtain uses up to 99 light barriers to create a vertical safety light grid across the escalator. Each light barrier consists of a transmitter module and a receiver module; if a person interrupts a light beam, the TLCU central unit detects the occupancy and withholds the release. The system works independently of ambient light and is self-monitoring and self-configuring according to EN 115:2008 (Cat. 4 / SIL 3).
