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.
