Potential safety issue with the X-ray high voltage generator incorporated into the FDR Visionary Suite X-ray diagnostic equipment. It was found that the contacts of the electromagnetic contactors used inside the cabinet of the X-ray high-voltage generator may weld, and the current might continue to be supplied to the power supply circuit even if the power of the device is cut off. As a result, it is possible that the circuit in question overheats and damages the surrounding parts. It may also cause smoke.
