Operation
A2. Tracking mode (controlled by Increment)
•
Max.
10 consecutive objects
in conveyor direction simultanously in the reading field,
reading one side with internal object tracking
Conditions:
•
Minimum object gap between two objects in conveyor direction:
50 mm (1.97 in)
•
Size of reading field = distance between sensor for beginning/end of object and object
release point parameterized (data output)
•
Autofocus mode "Differential background and tracking“, see
event-controlled focus position switchover
•
Incremental encoder connected to "IN 4" switching input
Possible reading triggers:
•
One external sensor (e. g. photoelectric reflex switch)
•
Command strings

Configuring no. of bar codes to be read: see
Chapter h) Parameterizing the evaluation
Note
To separate bar codes of the same type with identical contents, connect an incremental
encoder and activate the "Seperate codes dependent on reading angle" function. See also
