Description of Ultrasonic Transmitter Functions

Adjusting the switching points and the analog output.
And the switch output type and analog output type sensor can be programmed as the user want.
There are 8 types of output functions that can be programmed.
All the teaching routines are as follows,
The first step, teach one point with the related teaching in condition(High-level voltage or GND). Second step, choose a different distance(not the same as step 1) point and a different teacher in condition(not same as step 1). The program routine must be finished during the blue led flashing, the default value will be efficient if it 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 functions can be set.

Window mode normally opens and liner mode positive slope output function.
Window mode is normally closed and liner mode negative slope output function.
Single switching point, normally-open function.
Single switching point, normally-closed function.
Single switch point with hysteresis gap normally-open function.
Single switch point with hysteresis gap normally-closed function.
Detection of object presence-normal open function.
Detection of object presence-closed open function.

Switching point, Setting distance only after powering on. Because the internal clock assures it can’t be changed 5 minutes after power is on, so if want to change the switching point, the user can only set the request distance after power restart.
For the RS485 output type.
There are 2 kinds of working styles, One is for the auto measure, the sensor will measure the distance or level repeatedly, and the measurement period can be set by the art. The measurement result can be fetched every time.
The other style is the power save mode when the sensor is sleeping until the sensor received the inquiry command with pre-code. The communication protocol is Modus-RTU.
For example, the measurement result can be read by accessing the register 0x101 by Modbus protocol.

LED displays
		programming time	working time
Red LED	ON	—	Error occurred
	OFF	Working well	Working well
	Flash	Doing the echo lost program, For Single switching point, program, or Detection of the object.	—–
Yellow LED	ON	—-	Object detected
	OFF	——	Echo lost
	Flash	Teach in for the status ready, That means the sensor has locked the set distance for the program	—–
Blue LED	ON	Power on	Power on
	OFF	Power off	Power off
	Flash	Program period indication, Only the blue led flashes the program routine can be done	The program can be carried on

Indicators /operating means

LED blue	Flashing: program can be acted, this status The Blue led will flash around 5 minutes after the sensor power on, which indicates the sensor can be programmed, and then the blue led will perpetually turn on. To indicate the power status.
LED yellow	indication of the switching state flashing: during program function object detected
LED red	Normal working: light on indicates error detected. Programming: flashing, echo lost, that means the sensor is covered or no object in the front of the sensor,
