Part of the automatic restart system (WBS)
The light curtain is part of the automatic restart system (WBS) for escalators and moving walks: in accordance with EN 115, transmitter and receiver modules monitor the presence of people on the unit and automatically release the escalator again after an emergency stop. The signals are evaluated by the central unit. The D-Version is designed for Otis and Kone escalators, the E-Version for ThyssenKrupp and Schindler.
Features
- 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 C version is designed for escalators made by Schindler and ThyssenKrupp (Original RUDOLPH design); for new installations we recommend the current E version.
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
- Select the pre-assembled 9-module, 10-module or 11-module chain for the transmitter or receiver side.
- Mount the chain on the escalator side (one holder per module).
- Combine chains via connection modules; terminate the end of the chain with an inactive end module; connect to the central unit via adapter cable.
Important notes
- Installation/connection only by trained personnel and when de-energised.

External service display. The external service display serves to provide an extended view of a central unit’s display. Thanks to the cable, the external service display can be positioned optimally to read the status during a service operation on an escalator.
