Abstract
PURPOSE: To secure the alarm ringing by the fault signals at the fault occurrence time as well as to ensure confirmation of the state of the fault via the ITV on the central control board at the power plant or the like by installing the ITV camera to the control board at the site and the ITV to the central control board each.
CONSTITUTION: When single fault signal 11A of the apparatus and others enters one of collective fault display windows 1A which is incorporated into the control board installed at site 9, the window glows up. And collective fault signal 12A is supplied to control unit 3 as well as to alarm control unit 2 in central control room 10 to give the fault display to illumination-type push-button switch 4A, and at the same time the buzzer 5 rings. When the operator knows the fault through switch 4A and presses the switch, ITV switch unit 6 selects via unit 3 video signal 18A given from ITV camera 8A projecting display window 1A and then projects window 1A of site 9 on ITV7. Thus, the single fault occurring at the control board at the site can be confirmed in room 10.
