5 Teaching the OADM
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, 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 border 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 the factory settings
The sensor may be taught with the teach button or via the external teach input
During the teach-in process, the red LED and the alarm output provides a feedback
The red LED on the back side of the sensor and the alarm output indicate “run” mode if an object is within
the measuring range.
Attention:
Within 5 minutes after power on, the sensor can be taught via the button or the teach-in wire. After 5 minutes,
the teach-in button will be locked preventing accidental adjustment. The teach-in wire is active all the time.
