To teach a new range using the teach button
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 teach a new measuring range:
1. Hold down the button. The red LED will turn on, if the sensor can be taught.
2. Hold down the button for 2 more sec. The LED will start to flash.
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 4 mA
.
5. Briefly press the button again. The LED will stop flashing and will stay on for about 0.5 sec to
indicate that the first position has been stored. Then the LED will flash again.
6. Now place the target at the second position (the other end of the new range), which will produce
20 mA
.
7. Briefly press the button again. The LED will stop flashing and will stay on for about 2 sec to
indicate that the second position has been stored. The LED will then turn off and flash 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 both positions have been chosen too close to each other the new settings are not valid. The
sensor will respond with an extended flashing at the end of the teach procedure. The previous
settings are still valid and the new settings are lost. For more details see table below:

To teach a new range using the external teach input
Teaching the sensor using the external teach input is equivalent to the teaching procedure via the
button. There is no 5 min. time limit. The sensor may be taught any time. In addition to the LED, the
alarm output is used to indicate the state of the sensor for an external digital controller.
To reset the factory settings
Within 5 minutes after power up, the button may be used to reset the sensor back to the factory
settings. After finishing a teach procedure
,
the 5 minutes start again. After the 5 minutes, the sensor
does not respond to the button anymore.
1. Hold the button down. The red LED will turn on provided the sensor can be taught.
2. Hold the button down for 2 more sec until the LED starts flashing. Keep holding it down for
further 4 sec until the LED increases its flashing rate to first 8Hz shortly followed by 16Hz.
3. Release the button now: red LED is on for 2 sec.
4. Sensor factory settings have been successfully restored.
Teaching the sensor using the external teach input is equivalent to the teaching procedure via the
button. There is no 5 min. time limit. The sensor may be taught any time. The alarm output can be
used as an acknowledge signal for a control system.
