  • a first controller that has a control section responsible for sequence control of the medical device, wherein the first controller includes a first monitoring section which generates a first notification signal having an ON state or an OFF state corresponding to detection of a failure in the first controller;

    a second controller responsible for sequence control of the medical device if a failure occurs in the first controller, wherein the second controller includes a second monitoring section configured to detect a plurality of failures each having a respective priority, wherein the second controller generates a second notification signal in response to detecting one of the failures in the second controller, wherein the second notification signal has a flashing rate between an ON state and an OFF state identifying the respective priority, wherein one of the monitoring sections receives the notification signal from the other monitoring sections and inverts the second notification signal when the first notification signal is in an ON state; and
