1. Position object at 1.
2. Apply "L+" to "MF" for approximately 3 seconds until both LEDs ash
simultaneously.
3. When both LEDs ash alternately, position object at 2.
4. Apply "L+" to "MF" for approximately 1 second.
b The analog output has been taught-in. The ultrasonic sensor is in
normal operational mode.
NOTE!
You can teach-in the limit near the sensor or the limit
away from the sensor rst. You can teach-in the output
characteristics afterwards. → See the following section.
7.2.2 Conguringtherisingorfallingoutputcharacteristiccurve
Factory setting: "Rising output characteristic curve"
1. Apply "L+" to "MF" for approximately 13 seconds until both LEDs ash
alternately.
2. The green LED ashes. The orange LED indicates the current setting:
• On: Rising output characteristic curve
• O: Falling output characteristic curve
3. To change the setting, apply "L+" to "MF" for approximately 1 second.
The orange LED changes its status.
4. After conguring, wait approximately 10 seconds until the green LED
stops ashing.
b The setting has been applied. The ultrasonic sensor is in normal
operational mode.

7.3.1 Switchingbetweenteach-inandsynchronization/multiplexmode
NOTE!
The teach-in functionality is deactivated when
synchronization/multiplex mode is activated.
For synchronization/multiplex mode, the ultrasonic
sensors must be interconnected via the "MF" input (pin
5). You can operate a maximum of 20 UM18-2 Pro
sensors in synchronization/multiplex mode.
