8.2. Setting the Switching Threshold with the Teach-In Function
With the help of integrated Teach-In technology, the Sensor automatically calculates appropriate settings based
upon currently acquired values and saves them to memory after the corresponding key has been activated,
or after an external control signal has been received.
Two-Point Teach-In
The marking to be recognized is first taught into the Sensor in two steps, and the background is taught in subse-
quently. The Sensor then automatically calculates the ideal switching threshold based upon these two values.
The brightness relationship of the two intensities is irrelevant as far as switching characteristics are concerned.
Sensor output A is activated when the Sensor recognizes the intensity value which was taught in first. Sensor
output A is deactivated when the Sensor recognizes the intensity value which was taught in second.
