Abstract

PURPOSE:To cause brightness of an indicating lamp to be darkened at a boundary position without providing a lighting control pattern signal by utilizing fluctuation of data in a closed loop control system which includes a comparative circuit and a D/A converter. CONSTITUTION:A voltage value Va set by a level adjusting element 1 is input to a + input terminal of a voltage comparator 2. Whereas, an output voltage value Vb of a D/A converter 3 is input to a - input terminal of the comparator 2. The comparator 2 outputs 1 in case of Va>Vb and 0 in case of Va<Vb. An operation control circuit 5 receives output from the comprator 2 and then, increments a value output to the converter 3 when the output from the comparator 2 is 1 while decrementing them value when the output from the comparator 2 is 0. The circuit 5 also makes a conparison of the values output to the converter 3 with a proper data value stored in advance at all times. When the output value is within a proper range, an indicating lamp lighting-up signal is output to an indicating lamp circuit 4, while such lighting-up signal is not output when the output value is out of the proper range. Thus, brightness of the indicating lamp is darkened at a boundary position of the proper value.
