Outputs:
Analog output
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 and alarm output adapt to the new range. Two positions must be taught.
•
The first teach-in position aligns with 4 mA, the second position aligns with 20 mA
•
These teach-in positions are always just at the border of the new range (inside the measuring
range)
•
The sensor may be tauht 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.
