FST-2S1

The magnetic tape holds the unique position information as a magnetic code. It is mounted free-hanging in the shaft using a mounting kit and guided by means of a plastic guide on the sensor. The measurement is thereby always performed contact-free. The guide serves only to keep the tape within a defined distance to the sensor.

The position sensor is designed for the FST controller and, together with the Safebox S1 analysis unit, forms a complete system that satisfies the safety functions in the lift in accordance with EN 81-20/50 and EN 81-21.

Safebox S1 is used to monitor the car positions and speed as well as the shaft and car doors. Important safety-relevant requirements in the lift shaft are thereby ensured. Should a failure occur, the safety circuit opens and/or the safety brake is triggered depending on the event. The hardware components, such as relay contacts and microprocessors, are each present twice to ensure redundancy of all functions. The S1 Safebox can be installed in or on the control cabinet as well as in the machine room or in the shaft. The connection is pluggable, thereby enabling a fast, uncomplicated connection. The S1 Safebox is operated/diagnosed via the CAN interface of the FST-2XT/s. The system states are thereby clearly conveyed to the lift engineer via the FST-2XT/s graphic display as a complete or partial representation. Operational instructions and information are communicated via the FST Guide to help ensure understandable and fast commissioning as well as diagnostics of the complete system. The S1 and FST status and error messages are centrally stored in chronological plain text messages in the FST error list. This amalgamation of both systems enables optimum operation, diagnostics and transparency, all from a single source.
