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, apply "L+" to "MF" for approximately
10 seconds until both LEDs stop ashing.
b The ultrasonic sensor's switching point has been taught-in.
The ultrasonic sensor is in normal operational mode.
Congure the switching output as normally closed or normally open.

Factory setting: normally open
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: normally open
• O: normally closed
3. To change the setting, apply "L+" to "MF" for approximately 1 second.
The orange LED changes its status.
4. After conguring, wait approximately 10 seconds until the green LED
stops ashing.
b The setting has been applied. The ultrasonic sensor is in normal
operational mode.

7.2.1 Conguringthescalingoftheanalogoutput
The orange LED lights up when the object is located within the congured
scaling.
The minimum distance between the two scaling limits is 1 mm. A failed
teach-in is indicated by the simultaneous rapid ashing of both LEDs.
The original settings are retained.
