METHOD AND DEVICE FOR REDUCING THE ENERGY CONSUPTION OF A LIFT INSTALLATION

摘要

Device for reducing the energy consumption of a lift installation which can be alternatively brought into an operating mode and a standby mode. In the standby mode the lift installation is separated from a main energy source and connected with an auxiliary energy source, by means of which basic functions of the lift installation are maintained so as to enable later entry into the operating mode. The device comprises detecting means (19.1) in order to detect a use criterion describing the current use status of the lift installation. Moreover, power-saving means (11) with a microprocessor (30) are provided in order to bring the lift installation from the operating mode to the standby mode in the case of non-fulfilment of the use criterion and fulfilment of standby criteria and to bring it from the standby mode to the operating mode in the case of non-fulfilment of the standby criteria.
