Device functions and indicators – switching output
The sensor has two buttons for adjusting switching output OUT1 and analog output OUT2. Alternatively, all adjustments can also
be made via IO-Link. 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).

Adjustment of the switching points (Teach) using the control buttons
The switching point of the sensor is set to 400mm or 1300 mm (static 1-point teach) on delivery.
By means of a simple operating procedure, the switching point for output OUT1 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, control button 1 is permanently assigned to output OUT1 (see dimensioned drawing).

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 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.

2. To adjust output OUT1, press button 1 for 7 … 12 s 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.

Adjustment of the switching function (NO/NC) using the control buttons
Control button 1 can be used to switch the switching function of output OUT1 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 output OUT1 is set as NO contact ex works. If the switching
function is changed, the 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!

Adjustment of the analog output (Teach) using the control buttons
The choice of distances for start of measurement range and end of measurement range can be used to adjust the characteristic
curve of the analog output.
If an object is located outside of the taught measurement range, an error signal is output. A different analog signal is output here
by the sensor for the errors "distance too close: object outside of the measurement range" and "distance too far: object outside
of the measurement range".
Rising characteristic curve

range.
