Abstract
A device for reducing the energy consumption is used in an elevator installation which can be alternatively brought into an operating mode and a standby mode wherein in the standby mode the elevator installation is separated from a main energy source and connected with an auxiliary energy source, by means of which basic functions of the elevator installation are maintained so as to enable later entry into the operating mode. The device includes a detecting unit in order to detect a use criterion describing the current use status of the elevator installation. Moreover, a power-saving unit with a microprocessor is provided in order to bring the elevator installation from the operating mode to the standby mode in the case of non-fulfillment of the use criterion and fulfillment of standby criteria and to bring it from the standby mode to the operating mode in the case of non-fulfillment of the standby criteria.
