Transmitter and receiver chains for D version
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.
Features
- automatic restart system according to EN 115:2008
- safety light grid Cat. 4 / SIL 3, TÜV type-examined
- up to 99 light barriers per escalator side (approx. 30 m)
- self-monitoring and self-configuring
- independent of ambient light, no wearing parts
- protection class IP67, temperature range −20 … +65 °C
- Original RUDOLPH design
Areas of application
Field of use
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.
Operating principle
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).
Installation
- Mount the pre-assembled 3-module or 7-module chain on the escalator side (one holder per module).
- Combine chains to the required total length (up to 99 light barriers per side).
- Connect to the TLCU22-04 central unit via adapter cable; terminate the end of the chain with an end module.
Important notes
- Provide one holder per module.
- Connect to the TLCU22-04 central unit via adapter cable; terminate the end of the chain with an end module.
- Install only when de-energised.
