Outputs:
Analog output
Two sensor versions are available: with voltage output 0 ... 10 V or current output 4 ... 20 mA.
Alarm output (active high)
As long as there is an object within the actual - taught - measuring range and the signal received is
sufficiently strong the output is low.
If there is no object inside the actual - taught - measuring range or the signal received is of
insufficient strength or quality the alarm output is high.
Functions:
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. 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 using 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 using 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.
