Abstract

PURPOSE: To provide an emergency operating system for elevator, capable of protecting auxiliary motor from damages when emergency operation is over.
CONSTITUTION: When power sources R, S, T are again set into operation, timing relay 23 is energized and contacts 23a, 23b are closed, whereby current interruption detecting relay 21 is energized again so that contacts 21d, 21e are opened. Resultantly, a circuit 20 - 21a - 21c- 26a - 22 - 21b - 20 is established and relay 22 for detecting recommensement of operation of power sources is energized so that contacts 22a, 22b are closed and contact 22c is closed. On the other hand, through the circuit 20 - 21a - 22b - 23b - 29 - 21b - 20, a voltage is impressed on main motor contactor 1. At the same time, contact 29b is also closed and brake coil 28 is energized, so that main motor is released and rotated and a first gear 2 is also rotated. Thus, timing relay 26 is de-energized
