Foreign Matter Detection
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 Foreign detect timer [5q f-58]
starts.
3 When the timer is up, the current weighing value is ignored. Judgement is regarded
as fault. Rejection signal is transmitted from the AD-4404 to the selector.
4 The article is rejected with the selector.
The function can be used with automatic mode and conveyor stop mode.
