4. Description of Sensor Functions
Adjust the paramater
The ultrasonic sensor is equipped with a switch output featuring two teachable switching points. To set these points, the supply voltage, either -UB or +UB, needs to be applied to the TEACH-IN input. During this process, LEDs provide feedback, indicating whether the sensor has successfully recognized the target. Switching point A1 is configured using -UB, while A2 is set with +UB. The sensor offers the flexibility of eight different output functions.
It's important to note that the switching point and setting distance can only be adjusted after the power is turned on. The internal clock ensures that changes cannot be made after 5 minutes of power-on time. If there's a need to modify the switching point, the user must set the desired distance after restarting the power. This ensures a clear and controlled adjustment process for the sensor's configuration.

5. Installation conditions
If the sensor is installed at the environment temperature fall below 0℃,It should do well on the protective measures. In case of direct mounting of the sensor in a through hole using the steel nuts, it has to be fixed at the middle of the housing thread.
