Transmitter C-Version

The transmitter of the C-Version is a transmitter module of the light curtain system for the automatic restart system (WBS) of escalators.

Part of the automatic restart system (WBS)

The light curtain is part of the automatic restart system (WBS) for escalators: transmitter and receiver modules monitor the presence of persons on the unit in accordance with EN 115 and automatically release the escalator again after an emergency stop. The C-Version is the predecessor system for escalators from ThyssenKrupp and Schindler.

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

  1. Screw the transmitter module onto the matching transmitter cable (9-module/10-module/11-module).
  2. Fix the module with a stainless steel holder on the side of the escalator (opposite the receiver).
  3. Check the alignment with the opposite receiver module.

Maintenance & cleaning

  • Regularly inspect the modules and optical surfaces visually.
  • Clean dirty optics with a soft, lint-free cloth – no aggressive cleaning agents.
  • Check the status display of the central unit; faults are displayed and output.
  • No wearing parts – very low maintenance effort; defective modules can be replaced individually.

Important notes

  • Align transmitter and receiver exactly opposite each other.
  • One stainless steel holder is required per module.
  • Screw the modules onto the matching cable (9-module/10-module/11-module).
  • Install only when de-energised.
