Application The turning-folding door of a passenger train must be safeguarded via a safety edge.
1. Profile A suitable profile must first be selected. A special profile is required for this application. The profile geometry must ensure sufficient over travel, actua-tion from the side and correctly seal the door even at high speeds. Specific standards must also be taken into account with regard to the material.
2. Sensors and Control Unit The profile has an 11 mm chamber to minimize the actuating path; sensor types OSE-R 1101 and OSE-T 1103 must therefore be used. Since the sensors are wired directly in the door leaf, the sensor leads are sufficiently long and there is no need to use wiring suitable for energy guiding chains. The sensor signals are analyzed directly by the door control. The sensors can therefore be con-nected directly to the control system via a three-wire lead.
3. Integration into the Customer's Control System Since the sensor signal is simple and well docu-mented, it can easily be analyzed directly in the higher-ranking control system. If a microprocessor is available, it can be used to analyze the signal. The only additional requirements are an input filter and a power supply for the sensors. Further infor-mation about the dynamic sensor signal is avail-able upon request.
