Shaft copy system – Realization of elevator and safety functions.
The PSU02 is combined with the Ants LES02 sensor to realize elevator and safety functions in compliance with EN81-20/-21/-50. The Ants LES02 measures the absolute car position 100% slip-free. The PSU02 evaluates the safe position feedback and triggers by means of safety relays, jointly with the elevator control, the required safety functions. Therefore, the safe system, besides installation and maintenance time, allows above all saving costs.
