Performing automatic adaption
Automatic adaption using the "READ" button
Using the "READ" button, you can align the optical reader and automatically adapt all
relevant program settings. This function basically corresponds to the function "Full program"
of the WBM.
Requirements
● To use the function, you need a code in the target area of the reader.
● The WBM of the reader is closed.
Function description
The first time you press the "READ" button, the reader changes to "Adaption" status and an
"Alignment" LED is switched on. You can optimally align the reader to its target area using
the LED.
If the "READ" button is pressed again, the reader automatically adapts the camera settings
to the prevailing ambient conditions. You can find detailed information on this function in the
"Auto Setup" section of the online help. The process can take up to five minutes depending
on the model version and the code used. During this process, the "READ" LED flashes
green.
When the process has been completed successfully, the "READ" LED lights up in green for
5 seconds. If the process could not be completed, the "READ" LED lights up red for 5
seconds. After the adaption has been successfully completed, the settings are saved in the
specified target program. Finally, the reader returns to processing mode ("Start").
If errors occur during the process, they are indicated by a yellow or red flashing "READ"
LED. You can find detailed information on the errors in the section "Diagnostics via the LED
display (Page 185)".
You can find additional information about the functions and settings of the "READ" button in
the section "Settings > Options > Extras" of the online help.
Aborting automatic adaptation
You can cancel running automatic adaption in the following way:
● With open WBM: by pressing the "Cancel" button in the progress bar, by a page change
or by closing the WBM.
● With closed WBM: by pressing the "READ" button again. Note that during the first
adaptation step, the "Alignment", pressing the "READ" button signals the completion of
the alignment to the reader.
Additional function of the "READ" button
When the "Program" page of the reader's WBM is open, you can press the "READ" button to
switch result generation on or off.
