5.1 How to teach a new range using the teach button
Teaching a new measuring range:
Within 5 minutes after power-up, the button may be used to teach a new range. After finishing a teach
procedure, the 5 minutes starts again. After the 5 minutes, the sensor does not respond to pressing the
button. Seven steps to teaching a new measuring range:
1. Press (and hold) the button. The red LED will turn on, if the sensor can be taught.
2. Hold down the button for 5 more sec. The LED will start to blink.
3. Release the button.
4. Place a target at the first new position of the measuring range. This is the position that will later produce 0
V (or 4 mA) .
5. Briefly press the button again. The LED will stop blinking and will stay on for about 3 sec to indicate that
the first position has been stored. Then the LED will blink again.
6. Now place the target at the second position (the other end of the new range), which will produce 10 V (or
20 mA) .
7. Briefly press the button again. The LED will stop blinking and will stay on for about 3 sec to indicate that
the second position has been stored. The LED will then turn off and blink once more. Now the sensor is
ready to measure.
The new, smaller operating range is now set. The red LED now indicates whether an object is within the new
range (LED OFF) or not (LED ON)
If one of the new borders of the range was outside the standard range or the two positions were too close to
each other, then the new settings are not valid. The sensor will respond with an extended blinking at the end
of the teach procedure. The previous settings are still valid and the new settings are lost.
Timing of the teach procedure
If teaching was successful,
the LED will be on
If the teaching was not
possible, the LED will flash
