System Faults
Are classified as fatal and require immediate action. When an error is generated the
fault relay operates, permanently operating the reject device and/or stopping the
conveyor transport. In addition the Fault Relay LED
illuminates. If your detector is fitted with the Reports/Logs package the faults can be
accessed in the System Fault menu "View faults". All faults are described as either
passive (PSV), active (ACT) or as an event (EVT) the date & time accompany errors.
