Abstract

PURPOSE:To quickly cope with a slight abnormality of a main controller by comparing a load control signal in a stand-by controller and that in the main controller with each other by the stand-by controller and not only switching the controller through a monitoring device but also raising an alarm in case of noncoincidence between them. CONSTITUTION:A main controller 1 generates the load control signal in accordance with the operation of an operation part A to control a load part B. In this case, a stand-by controller 2 generates the load control signal and compares this signal with the load control signal generated by the controller 1, and a noncoincidence signal is supplied to a monitoring device 4 if they do not coincide with each other. Then, the device 4 switches the controller 1 to the controller 2 through a switching device 3 and an alarm is raised. By this constitution, even a slight abnormality of the main controller is immediately detected to quickly cope with this abnormality.
