摘要： An elevator safety circuit includes a plurality of relays; safety logic for monitoring status of the plurality of relays, the safety logic generating an output signal in response to the status of the plurality of relays; and a processor controlling operation of an elevator drive in response to the output signal; wherein at least one of the relays is a forced guided relay and at least one of the relays is other than a forced guided relay.

摘要： A system for managing elevator power includes a power line connected to a power grid, a motor connected to the power line and configured to receive power from the power line to drive an elevator, an alternative power source connected to the motor, and a power control system configured to control the power line to supply power to the motor to drive the elevator, to detect a predetermined threshold value of power supplied from the power line, and to supply both power from the power line and power from the alternative power source to the motor based on a determination that the predetermined threshold value of power is supplied from the power line.
