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 start 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 seconds. 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 0V (or
4mA) .
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 10V (or 20mA) .
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.
