PURPOSE:To improve the reliability of the titled system by presetting a presettable counter in a fixed cycle by the software and giving a decision on an operating fault when the count value of said counter exceeds the set value. CONSTITUTION:An automatic restart control system comprises an accessable preset command register 1 using a program, presettable counter circuits 20-2n, a setting switch, comparators 30-3n which compare the value of said switch with the output values of circuits 20-2n respectively, a detecting circuit 4 which decides the outputs of comparators 30-3n and a restart circuit which works on the output of the circuit 4. The circuit 5 is actuated automatically when the coincidence is obtained between the output values of circuits 20-2n and the set value of the setting switch. |
