4. Description of Sensor Functions
Adjust the paramater
The ultrasonic sensor features a switch output with two teachable
switching points. These are set by applying the supply voltage - UB
or + UB to the TEACH-IN input. The supply voltage must be applied
to the TEACH-IN input for at least 1 s.LEDs indicate whether the
sensor has recognised the target during the TEACH-IN procedure.
Switching point A1 is taught with - UB,A2 with +UB. Eight different
output functions can be set. Switching point, Setting distance only after power on. The internal
clock can assure can't be changed after 5 mins when power on. If
want to change the switching point, the user can only setting the
request distance after power restart.

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.
