Abstract
PURPOSE: To attain a self-diagnosis by providing the 1st rectangular-wave signal generating circuit, a digital processing circuit having a program to generate the 2nd rectangular-wave signal and logic circuits that detect levels of both the rectangular waves.
CONSTITUTION: Oscillating circuit 3 outputs the 1st rectangular wave (a) to digital processing circuit 2 and logic circuits 4 and 6. Digital processing circuit 2 generates an output (2nd rectangular wave) for a fault diagnosis which becomes high in level only when input waveform (a) is at a high level. This 2nd rectangular waves are also applied to logic circuits 4 and 6. While waveform (a) stays at the high level, the 1st logic circuit 4 judges that when a fault diagnosis output from digital processing circuit 2 never becomes high in level even once, digital processing circuit 2 is out of order. The 2nd logic circuit 6, when waveform (a) is at the low level and the fault diagnosis output is at the high level, judges that digital processing circuit 2 is in trouble.
