Abstract

PURPOSE:To monitor many pieces of information of the positive polarity and negative polarity to be monitored which belong to units, by displaying them on a single display circuit with a small number of connection lines by providing intercepting circuits, etc., which intercept or output pieces of information of the positive polarity to be monitored according to a control signal. CONSTITUTION:Connection lines obtained by successively connecting monitored- information lines (1-1-1-3)-(3-1-3-3) of units 1-6 to be monitored which are respectively equipped with intercepting circuits 1-4-6-4 intercepting or outputting pieces of information of the positive polarity to be monitored according to a control signal by one from every unit in parallel are changed over via switch 7 to obtain a single output. Similarly, the information lines that correspond to pieces of information of the negative polarity to be monitored are changed over via switch 12 to obtain a single output. Then, control signals corresponding to intercepting circuits for the positive polarity and negative polarity are selectively supplied to switch 13 and switches 7, 12 and 13 are operated to monitor the pieces of information to be monitored on single display device 9.
