Abstract
The invention relates to a procedure and an apparatus for analyzing elevator functions and detecting deviating functions. By monitoring signals associated with traffic events in the elevator system, an analyzer connected to the elevator learns the normal operation of each elevator independently. Signals occurring during operation are compared with the information thus acquired and a failure alarm is produced or the information is altered to make it accord with the new, changed situation.
