ABSTRACT:
X-ray examining apparatus generally conprise various supervisory circuits which must prevent, for example, that the table top is lowered too far when the table is in the vertical position or that the pressure exerted on the patient becomes too high. The quantities to be supervised are simulated by the voltage to be derived from the potentiometer, and if such a potentiometer becomes defective it may occur that the supervisory device is not actuated. It is also possible that the supervisory circuit itself is defective. In order to detect such a defect, a fault-simulation generator is provided which during operation is connected at regular instants to the input of the supervisory circuit instead of to the potentiometer tapping and which generates voltages which correspond to a failure. If the supervisory circuit is not actuated in such a case, it means that it is defective. This defect can be signalled by the test circuit.
