Teaching The Oadm - Baumer OADR 20I6 Series User Manual

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.
