PURPOSE:To execute quickly one-behavior control without receiving a slave station-side equipment selection end signal by allowing a master station side to display and alarm the operating state of an equipment selection relay of the slave station side in advance. CONSTITUTION:In case of one-behavior control from a master station remote supervisory controller 1, when any of equipment selection relays 9 of a slave station remote supervisory controller 2 is operated for a preset constant time or over, the master station lights a fault display lamp 7 and rings an alarm buzzer 8 to recognize the operating state of the equipment selection relay of the slave station side at the master station even at the non-selection state. Moreover, Interlocking is applied so as not to control by an equipment selection interlock circuit 4 even when the equipment selection switch 3 is depressed. Thus, quick one-behavior control is attained.
