Device functions and indicators
The sensor has two buttons for adjusting output OUT1 and output OUT2. Alternatively, all adjustments can also be made via IO­Link. The multi funct teach input can be used to perform the 1-point teach and the changeover of the switching function (NO
contact/NC contact).

HTU418B ADVANCED ultrasonic sensors with 2 switching outputs
Adjustment of the switching points (Teach) using the control buttons
The two switching points of the sensor are both set to 400mm or 1300 mm (static 1-point teach) on delivery.
By means of a simple operating procedure, the switching points for each output can be individually taught to an arbitrary distance within the scanning range with 1-point teach (static) or 2-point window-teach (static).
Moreover, the output function can be switched from NO contact (NO - normally open) to NC contact (NC - normally closed). For the adjustment, an individual control button is permanently assigned to each output (see dimensioned drawing).
1-point teach (static) 2-point window-teach (static)
1. Place object at desired switching distance. 1. First, place object at desired switching distance for switching point 1.
2. To adjust output OUT1, press button 1, to adjust output OUT2, press button 2 for 2…7s until the yellow LED flashes at 3Hz.
3. Release the button at the end of the teach event.
The current object distance has been taught as the new switching point.
4. Error-free teach: LED states and switching behavior according to the dia­gram shown above. Faulty teach (object may be too close or too far away – please note scan­ning range): yellow LED flashes at 5Hz until an error-free teach event is performed. The affected output is inactive as long as there is a teach error.
1) See table "Switching behavior with 2-point window-teach as a function of the switching function"
Notice! All operating functions are identical for outputs OUT1 and OUT2.
2. To adjust output OUT1, press button 1, to adjust output OUT2, press button 2 for 7 … 12s until the yellow and green LED flash alternately at 3Hz.
3. Release button. The sensor remains in teach mode and the LEDs con-
tinue to flash.
4. Then, place the object at the desired switching distance for switching point 2.
Notice:The minimum distance between the switching points is as follows:
5. Briefly press the button again at the end of the teach event.
The switching window has been taught.
6. Error-free teach: LED states and switching behavior according to the dia­gram shown above. Faulty teach (object may be too close or too far away – please note scan­ning range): green and yellow LED flash at 8Hz until an error-free teach event is per­formed.

Adjustment of the switching function (NO/NC) using the control buttons
The control buttons can be used to switch the output function from NO contact to NC contact (or vice versa). To do this, proceed as follows:
Action / Description Control button
Changeover of the switching function:
Switching outputs OUT1 and OUT2 are set as NO contact ex works. If the switching function is changed, the corresponding switching output is changed to the opposite state (toggled).
Notice! For 2-point window-teach, the switching behavior is dependent on the selected object distances for switching points 1 and 2. See previous page!

Adjusting the switching points (teach) via the teach input
The switching points of the sensor outputs OUT1/OUT2 are set to 400mm or 1300mm on delivery.
By means of a simple teach event, the two switching points can be individually taught to an arbitrary distance within the scanning range. The Leuze PA1/XTSX-M12 teach adapter can be used for this purpose. The adapter can also be used to easily switch the output function from NO contact to NC contact.

1. Place object at desired switching distance. 1. Place object at desired switching distance.
2. For the adjustment of output OUT1, connect input Teach-IN to GND for 2…7s (Leuze teach adapter: position "Teach-GND"). The current state of output OUT1 is frozen during the teach event.
3. The yellow LED flashes at 3Hz and then remains on.
The current object distance has been taught as the new switching point.
4. Error-free teach: switching behavior according to the diagram shown above. Faulty teach (object may be too close or too far away – please note scan­ning range): yellow LED flashes at 5Hz until an error-free teach event is performed. The output OUT1 is inactive as long as there is a teach error.
Notice!
Please note that the switching point is taught when GND is connected and the output function is reversed when
is connected. If no sensor action is desired, pin 2 must remain unconnected!
