PURPOSE:To ensure effective works of maintenance and inspection and prevent drop of user service by separating a cage from the parallel run management condition when an inspection switch is put on for lighting up, providing an operational circuit for changing over into the proprietary condition, and thereby driving the elevator proprietarily at the time of maintenance and inspection. CONSTITUTION:When No.1 unit is to be worked for maintenance an inspection, operator shall get on the cage of No.1 unit, and a switch 1A for inspection is turned on. Now a relay 2A for inspection of an inspection lamp is energized, and the contact 2A1 is separated. This shuts off the power to a get-on place call circuit 6A and a cage allocation circuit 3A, and even though a get-on place call is generated in the elevator, this get-on place call will not be registered in the No.1 unit, and neither the No.1 unit will respond to the get-on place call. When a cage call register is generated, however, a cage call register circuit 4A senses the floor which was cage call registered, and a cage advance circuit 5A operates on the basis of this sensing signal to permit the cage to go directly to the floor cage call registered. |
