3.8.10 Barcode reader
Where present, the reader must be mounted upstream of the probe, in order to read a code
stamped on the pack; it must be connected to connector J11 on the ALM card. If the code is
recognized, the reader sends a command to the Metal Detector to select the relevant product type.
The time required by the THS/21 to process the barcode is usually insignificant, but becomes
significant if the detection mode, or band, is changed due to a modification in the type of product.
When the Metal Detector receives the signal to change product type, an internal adjustment
procedure is activated to adjust the length of the minimum distance between two packs with
different codes, that is to say containing different products.

Installing the barcode reader closer than 3000 mm will result in product ejection during two
detection mode cycles. After the cycle time, the system will be operated normally.
