The foreign matter detection is the function to reject an article including foreign matter.
The system consists of the AD-4404 and the foreign matter detector.
The rejection is performed with the following procedure.
1 When an article including foreign matter is detected, a signal is transmitted from the
foreign matter detector to a preset I/O control interface terminal of the AD-4404.
2 When the AD-4404 receives the signal, the
starts.
