Adjusting the switching points via the teach button
The switching points of the sensor for both outputs are set to 3500mm or 6000mm (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). An
LED is permanently assigned to each output for the setting.
Selecting the output that is to be taught: OUT1 or OUT2
1.Press the teach button for ≥2s to activate teach mode. The yellow LED (OUT 1) flashes at 1Hz.
While in this state, output OUT 1 can be taught.
2.To teach output OUT 2, briefly press the teach button again. The blue LED (OUT 2) now flashes at 1Hz.
While in this state, output OUT 2 can be taught.
3.Briefly press the teach button again to toggle between outputs OUT 1 and OUT 2 in this state. The flashing LED indicates which
output is ready for teaching:
yellow LED flashing = OUT 1 ready for teaching,
blue LED flashing = OUT 2 ready for teaching.
Teaching output OUT 1 or OUT 2
First activate the previously described teach mode for output OUT 1 or OUT 2.
1-point teach (static) 2-point window-teach (static) 1)
1) See table "Switching behavior with 2-point window-teach as a function of the switching function"
1.Place object at desired switching distance. 1.First, place object at desired switching distance for switching
point 1.
2.To adjust the selected output, press the teach button for
2…7s until the yellow LED (OUT 1) or blue LED (OUT 2)
flashes at 3Hz.
The current state of the selected output is frozen during the
adjustment process.
2.To adjust the selected output, press the teach button for
7…12s until the yellow (blue) and green LEDs flash alter-
nately at 3Hz.
3.Release the button.
The current object distance has been taught as the new
switching point.
3.Release the button. The sensor remains in teach mode and
the LEDs continue to flash.
4.Error-free teach: LED states and switching behavior accord-
ing to the diagram shown above.
Faulty teach (object may be too close or too far away – please
note scanning range):
green and yellow (blue) LEDs flash at 8Hz until an error-free
teach event is performed.
The selected output is inactive as long as there is a teaching
error.
4.Then, place the object at the desired switching distance for
switching point 2.
Note:The minimum distance between the switching points
is as follows:
scanning range of 3500mm: 350mm
scanning range of 6000mm: 600mm
5.Briefly press the teach button again to complete the teach
event.
The switching window for the selected output was taught in.
6.Error-free teach: LED states and switching behavior accord-
ing to the diagram shown above.
Faulty teach (object may be too close or too far away – please
note scanning range):
green and yellow (blue) LEDs flash at 8Hz until an error-free
teach event is performed.

Adjusting the switching function (NC/NO) via the teach button
The switching function of the sensor is preset as follows on delivery:
OUT 1: NO contact
OUT 2: NC contact
The output function for each output can be individually switched from NO contact (NO - normally open) to NC contact (NC - nor-
mally closed) and vice versa. If the switching function is changed, the switching output is changed to the opposite state (toggled).
First activate the previously described teach mode for output OUT 1 or OUT 2.
Changeover of the switching function
1.To change the switching function of the selected output, press the teach button for longer than 12s.
The current state of the selected output is frozen during the adjustment process.
2.The green and yellow (blue) LEDs flash alternately at 3Hz.
If the yellow (blue) LED is ON afterwards, the selected output operates as an NO contact.
If the yellow (blue) LED is OFF afterwards, the selected output operates as an NC contact.

Synchronization of multiple HTU330 ultrasonic sensors
If adjacent ultrasonic sensors receive the signals of other sensors, so-called crosstalk occurs, which leads to faulty measurement
results. Through temporal synchronization of the adjacent sensors, this can be avoided. Via the Sync/MUX input, the HTU330
ultrasonic sensors can be synchronized in 2 different ways:
Synchronous operation
In this operating mode the mutual interference of adjacent sensors can be avoided; a minimum mounting distance between the
sensors is to be maintained, however:
Sensors of the same type are wired together in a network according to the following diagram. A synchronization pulse from the
control activates synchronous operation.
The devices work in synchronous operation with a simultaneous transmission pulse. The response time of the individual sensors
in the network corresponds approximately to that of a single sensor.

Sensor 2 Sensor 1Sensor n
NOTE
Please make certain that the wiring is performed accord-
ing to the connection diagram.
The Sync/MUX pin 5 on all sensors in the network must
be connected to one output of the control. Generation of
the synchronization signal for all sensors in the network
occurs via the control.

Multiplex operation
In this operating mode the mutual interference of adjacent sensors can be reliably avoided. For this purpose, each sensor is wired
with a separate output of the control.
The devices operate in multiplex operation with a cyclically time-delayed transmission pulse and are switched to a passive state
outside of the active phase.
Multiplex operation wiring schematic
Timing diagram for multiplex operation
Resetting to factory settings
The sensor can be reset to the factory setting (one switching point each at 3500 mm or 6000 mm).
Resetting to factory settings
1.When switching on the supply voltage (during power-on), press the teach button for >5s.
2.Release the button. The green, yellow and blue LEDs flash alternately and very quickly for a brief time.
The sensor was reset to the factory setting:
switching output OUT 1: NO contact, 1 switching point at 3500 mm or 6000 mm (static 1-point teach),
switching output OUT 2: NC contact, 1 switching point at 3500 mm or 6000 mm (static 1-point teach).
