Abstract RU 2448891 C2

FIELD: transport.

SUBSTANCE: proposed method is reduced to practice by using device 11 with microprocessor 30. Registration devices 19.1 are used to define utilisation criterion. Elevator operating conditions selectors are used to change elevator 10 from operating conditions into waiting mode in non-fulfillment of utilisation criteria and fulfillment of waiting criteria, and into operating mode from waiting mode in non-fulfillment of waiting criterion. In waiting mode, elevator unit is partially disconnected from main power source.

EFFECT: reduced power consumption in waiting mode.
