Calibrating the label gap / blackmark sensor:
LERC10 label eye sensor
AUTOSET
Simply put the gap in view and push and hold the AUTOSET button for 1 second. The AUTOSET LED
will remain on when the setup is complete. If the setup is not adequate, the AUTOSET and Output
LEDs will flash 3 times. This may indicate a backing material that is too dense to penetrate.
UP/DN Adjustments
The Label Eye sensor has the ability to "tweak" the setup incrementally. Simply momentarily tap
the AUTOSET (UP ˄) button, or LT/DK (DN ˅) button to adjust the sensor to a more stable and
repeatable setting. This feature is used when the AUTOSET does not provide the optimum setting
initially.
Example: If the label backing material is inconsistent, or the label material has more translucent
areas coming into view, then the sensor may need to be adjusted slightly for this rare occasion.
Having the ability to fine tune the sensor for changing conditions provides a solution that is easy to
implement and simple to understand.
Light/Dark
Push the LT/DK button to change output from Dark On to Light On...output turns on when label in
view, or output turns on when gap in view.
1.
Cut a piece from the label material which has a blackmark on it. Then put the blackmark exactly to
under the middle of the LABEL • EYE™ text on the sensor, where the small dot indicates the exact
position of the sensor beam.
2.
Keeping the blackmark under the sensor beam, press and hold the
‘AUTOSET’
button on the sensor
until only the green AUTOSET LED is lit constantly (the red output and the green autoset LEDs will
start flashing first and then red LED goes off and green LED stays lit if calibration is successful).
3.
Check detection by moving a label (not blackmark) into the sensor beam. If sensor is properly
calibrated, then the red output indicator LED will go on indicating that the sensor can differentiate
between blackmark and label. When the blackmark is under the sensor, then only the green
autoset LED is lit.
4.
Repeat the calibration in case you do not see the same result as described in point 3 above.
