5.2 How to reset the factory settings using the teach button

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 starts again. After the 5 minutes, the sensor does not

respond to the button.

1. Push the button. The red LED will turn on, if the sensor can be taught.

2. Hold down the button further 5 sec. The LED will start to blink. DO NOT RELEASE the button now. Wait

another 10 sec until the LED is ON without blinking. Factory settings have been restored to the sensor.

3. Release the button.

5.3 How to teach a new range using the external teach input

Teaching the sensor via 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 at any time.
