Description of Sensor Functions Adjusting the switching points and the analog output. The switch output type and analog output type sensor can be programed as the user want. There are 8 types of output functions can be programed. All the teach routine as follows, step 1 teach one point with the related teach in condition (High level voltage or GND). step 2 choose a different distance (not the same with step1) point and a different teach in condition (not same with the step1). The program routine must be finished during the blue led flashing; the default value will be efficient if the not. 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 recognized the target during the TEACH-IN procedure. Switching point A1 is taught with - UB, A2 with +UB. Five different output
