Shaft copy system – Realization of elevator and safety functions.
The PSU01 is an SIL3-certified safe system consisting of a sensor (Ants LES01) and an evaluation unit (PSU) for implementing lift and safety functions in accordance with EN81-20/21/50. The Ants LES01 is used to determine the absolute car position 100% slip-free. The PSU evaluates the safe position feedback and triggers the required safety functions via safety relays together with the lift controller. Existing limit switches as well as inspection limit switches can be replaced when the shaft head/pit is shortened. In addition to UCM, numerous other EN81-20/21/50 requirements can also be met. The safe system thus not only saves installation and maintenance time, but above all costs.
