ABSTRACT:
In an operating system for an elevator wherein operation means are disposed in a plurality of cages, cipher code memory means for storing predetermined operating sequences of the operation means are disposed for the respective cages, and switching means are disposed for comparing operating sequences of the corresponding operation means with the stored predetermined sequences when the operation means are operated and to switch the corresponding cages to predetermined runs when the operating sequences agree; an common cipher code alteration means is provided for altering the stored predetermined operating sequences to different operating sequences for all the cages.
When the cipher code alteration means is manipulated, all the cipher code memory means are commanded to alter their cipher code contents at once, whereby the single altering manipulation suffices to complete the cipher code alterations for all the cages.
