Abstract
PURPOSE:To prevent failure of equipment in advance, due to jam of control, by monitoring the jam earlier through a timer in a computer with several sections for the monitor of jam of control circuits, and by outputting the display of operation of relays in normal cases to peripheral devices of the computer. CONSTITUTION:If a condition 21 out of progress conditions 10 of a control circuit is not satisfied, since additions 17, 18 are set but additions 19, 20 are not set, an end signal 11 from the control circuit and an input signal 24 to the computer are not made. That is, control is jammed. Thus, the input signal 24 of the computer from the control circuit to the end is not input, and addition circuits are set when the estimate time from the control circuit to the end passes with an inner timer signal 27, to produce an alarm signal 30. The operation personnel can know the jam of control from the control circuit. Further, the operation personnel can immediately know the unsatisfied progress conditions 21 through the collation of the illuminating light of relay status of the control circuits of the relay panel, by indicating the status of relays at the normal state of circuit elements 9 from the control circuit on CRT and the like, at the same time with this alarm.
