The disclosure relates to a method for operating a medical device, (e.g., an imaging apparatus such as an X-ray device or magnetic resonance tomography unit), and a fault monitoring apparatus for carrying out the method. The fault monitoring apparatus is connected to the medical device via a signal connection. In the method, the fault monitoring apparatus receives an item of status information from the medical device and stores the item of status information in a system state. Further, the fault monitoring apparatus compares the stored system state with a predetermined target state, and, depending on the comparison, releases a function of the medical device, wherein the predetermined target state has a successfully executed function test.
