4  METAL DETECTOR 

The  opportunity  to  connect  metal  detectors  has  been  introduced. At  the  process 
entrance,  the  machine  programs  the  recipe  detailed  in  the  process  (parameter 
inside  the  METAL  group)  in  the  metal  detector. The  storage  of  the  recipe  in  the 
metal detector must be carried out on board metal through the procedure of data 
capture/calibration. 
The machine can connect to different models of metal detector 
It  is  also  possible  to  have  in  the  checkweigher  report  the  number  of  products 
rejected by a metal, which in this case is connected via input/output line.
