The statical Teach-in mode (TM/TB) allows the teach of mark and
background at the same time (one after the other but independently of
the order) or separately. There is no need to teach always both mark and
background.
• Place a paper under the sensor and switch to the Teach-in mark
(TM).
• Teach-In starts with a continuous value capturing. The object’s
color may change. When the switch position changes, the last
captured value will be saved as the marks value. During TM mode,
the green and the yellow display LED are flashing simultaneously
(f = 2.5 Hz).
• Remove the paper and activate the Teach-in background (TB)
mode. Measure the contrast color of the background (the belt).
During TB mode, the green and the yellow display LED are flashing
simultaneously (f = 2.5 Hz).
• Activate the switching mode (S). Control the set contrast values by
placing a paper under the sensor by hand. The LED should
If the teach-in was not successful, the LEDs start flashing alternating
with a frequency of approx. 8.0 Hz. The sensor returns to the switch
mode (normal operation) after 7 seconds without changing the saved
values.
Cause: Maybe the contrast was too bad. Try to teach-in the paper on the
darkest color passing the sensor.
