3.9.10 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.
In this cases, a
minimum distance between two packs with different codes
, shall be granted.

.
The following code formats are supported:
- XXXXXX<CR>
- XXXXXX<CR><LF>
- <STX>XXXXXX<ETX>
Where XXXXXX is a string of 48 characters (max.)
Refers to the electrical connections description (par.3.7.1) for the requested electrical requirements
of the barcode reader.

: Distance between the packs of different products
DDD
: Distance allowing the Metal Detector to change configuration after a Band/Detection mode change, before the
pack reaches the Probe. It dependes on pack speed, sensitivity settings and Probe dimensions and it must be
determined experimentally.
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.
