CONSTITUTION:When stop or emergency stop instruction is not made, the output signal 8 is taken place from the output circuit 71 with the AND condition of the AND circuit 12 satisfied with the output instruction of each control circuit. Further, stop or emergencey stop instruction is taken place, the output signal 8 is produced with the output instruction of each control circuit under the OR condition of the OR circuit 14 satisfied.
