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.
