Title:
FAULT DISPLAY FOR POWER PLANT
Document Type and Number:
Japanese Patent JPS58121410
Kind Code:
A
Abstract:
PURPOSE:To obtain a compatible fault display circuit and to give a display system flexibility in alternation, extension, etc., by interrupting a fault detection signal corresponding to a fault occurring newly. CONSTITUTION:When a contact for circuit closure in a falt detection contact group 1a is operated firstly, a detecting circuit 18 and a detecting circuit 19 generate outputs. A gate circuit 20 generates a fault detection signal (i) lagging said outputs. The signal (i) is inputted to an ANN circuit 5a and a holding circuit 21 generates and holds an output. On receiving it, an output circuit 24 sends out a lamp flashing output and an alarm output. Once an operator presses a confirmation button after confirming the genertion of the display and alarm outputs, a signal K is inputted. Then, a holding circuit 23 operates to hold the output. The output circuit 24 receives the output to generate a successive display signal as a lamp display signal l while interrupting the alarm signal (b).
