5 Teaching the OADR
Every sensor is delivered with the factory setup (max. measuring range). The teach-in feature was designed
to choose a smaller range within the nominal measuring range for optimizing the resolution and linearity.
Output current, output voltage and alarm output adapt to the new range. Two positions must be taught.
The first teach-in position aligns with 0 V (or 4 mA) the second position aligns with 10 V (or 20 mA)
These teach-in positions are always just at the limit of the new range (inside the measuring range)
The sensor may be taught more than 10'000 times in its lifetime
The sensor can always be reset to its factory settings
The sensor may be taught using the external teach input
During the teach-in process the red LED provides visual feedback to the operator
When in running mode the red LED on the back side of the sensor indicates whether there is an object
within the measuring range or not.
