PURPOSE: To insulate a contact point of a door chain circuit from a safety chain circuit in a separation circuit, prevent traveling in a door opened state and attempt safety with a safety network to excite a safety chain circuit relay to transmit a safety chain circuit state signal to a signal processing device. ;CONSTITUTION: A door chain circuit 50 insulated from a safety chain circuit 52 is constituted by furnishing a series of door contacts 42, 44,...48 of an elevator, and a separation coil 54 to independently check a state of this circuit 50 is provided on the same circuit 50. The safety chain circuit 52 is constituted by furnishing a series of contact points 66, 68,...70 related to various conditions for authorization, and they are connected in series to related coils 54, 56 and contact points 76, 78 and contact points 72, 74 related to rear door relay coils 80, 82. A series of the contact points 72, 74, 76, 78 is closed to excite a relay coil 84 of the safety chain circuit, a normally opened contact point 58 of the safety chain circuit relay coil 84 is monitored by a processor 30, and a motor 18 is driven at the time of closing the same contact point 58.;COPYRIGHT: (C)1995,JPO
