PURPOSE:To protect quickly and properly a system and an attachment device against various environmental abnormalities, by controlling an output circuit directly without the intervention of a computer by the control signal of a signal converting part. CONSTITUTION:Temperature sensors 1a-1c are connected together with other sensors to a malfunction detecting part 3 through a sensor disconnecting part 2. When discriminating the occurrence of an abnormality, the detecting part 3 drives a display and alarm part 4 to report it and sends a signal indicating the occurrence of the abnormality to a signal converting part 6. The signal converted by the converting part 6 is given to an operating setting part 7, and the setting part 7 outputs a proper control signal to a signal converting part 8 in accordance with a program set preliminarily in the circuit. The converting part 8 converts the given signal to a form which can be accepted by a computer 9, and this converted signal is outputted to the computer 9. The control signal from the computer 9 is applied to an output circuit 11 through a signal converting part 10. The circuit 11 is connected directly to the converting part 8, and the circuit 11 is controlled directly by the output of the converting part 8 in case of emergency. |
