Siemens has completed an investigation of the reported event.Assessment of the log files does not indicate a system failure or malfunction and no non-conformity was identified.According to the log files, movement of the system was possible at slow speeds in override mode.The technician went on site and performed troubleshooting; however, he could not find any defect and the system was running properly.Since the situation on site stabilized as a result of the service call and the original problem no longer existed, it was not possible to determine the cause of the fault.According to system specialists, it is conceivable that the proximity switch responsible for collision detection was activated for a short time, which was then rectified by the service intervention on site.The log file shows temporary actuation of the proximity switch, confirming this theory.Another indication of a temporary problem is that the system ran as specified after the on-site actions and no parts were replaced, nor could a defect be detected.The system has been tested successfully by the local service organization.The error has not been reported again.A possible general fault that would require corrective measures on the installed base could also not be determined by the investigation.After detailed investigation, the incident is not classified as a reportable event as neither serious injury, death nor an unexpected, prolonged hospitalization of the patient or any other person occurred or could be expected.
