摘要

In a elevator safety - control device and an elevator safety - a control method according to this invention, when the elevator safety - control device detects an abnormality in itself, in that calculation results are compared by a plurality of processing devices are obtained, a stop instruction for a next stage output to a control device, in order to stop cabin on the next stage, and, if a time limit of a timer - device, which in each processing device is provided, is reached, a safety controller is implemented, in order to stop the cabin. To this time form the timer - devices a the dual system and a function for the diagnosis of the reliability of the timer - devices of the dual system is provided by respective count values are compared, the timer - devices.
