Ultrasonic Water Level Sensor function analog
The analog output can be set through RS485, and the ultrasonic water level sensor can work in 8 modes. The specific reference is as follows:
Step 1: Connect to the host computer through serial port debugging assistant or modus debugging assistant.
Step 2: Set a near point reference distance point.
Step 3: Set a far point reference point
Step 4: Set the output voltage or current of the near-point reference point.
Step 5: set the output voltage or current of the far point reference point.
Step 6: Set the analog output to switch characteristic selection.
Step 7: Set the analog output as linear output or switch output option.
Step 8: Reset the sensor to make the new parameters take effect.
8 working modes of the KUS630 ultrasonic water level sensor.
- Open window mode by default
- Windowed mode is turned off by default
- 3: Single-point mode is turned on by default
- Single-point mode is turned off by default
- Single-point hysteresis mode is turned on by default
- The single-point hysteresis mode is turned off by default
- The presence or absence of detection mode is turned on by default
- The presence or absence of detection mode is turned off by default
485 output data
485 output data is in MODBUS-RTU format. Refer to the software instruction manual for details.

3. Description of ultrasonic water level sensor | ultrasonic proximity sensor
The switch output type and analog output type of ultrasonic proximity 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.
Ultrasonic proximity sensor feature
The ultrasonic proximity 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 ultrasonic proximity sensor has recognized the target during the TEACH-IN procedure.
Switching point A1 is taught with – UB, A2 with +UB. Five different output functions can be set.
1. Window mode normally-open and liner mode positive slope output function.
2. Window mode normally-closed and liner mode negative slope output function.
3. Single switching point, normally-open function.
4. Single switching point, normally-closed function.
5. Single switch point with hysteresis gap normally-open function.
6. Single switch point with hysteresis gap normally-closed function.
7. Detection of object presence-normal open function.
8. Detection of object presence-closed open function.
Switching point, Setting distance only after power on. The internal clock can assure can’t be changed after 5 minutes after power on. If want to change the switching point, the user can only set the request distance after power restart.
