N type (Potentiometer)

The detection range can be individually set to between 0.2 m and 3 m (0.7 ft and 10 ft) using the potentiometer located
at the rear of the sensor.
Important:
When setting with the potentiometer (Figure 14) as the settings are not printed on the sensor. Take a small screwdriver
and turn the potentiometer according to the potentiometer teach-in procedure (Figure 13).

Teach:
 Mount the sensor at its final position.
 Switch on the power supply.
 Set the sensor in the teach mode. (Step 1 and 2 of
Figure 13)
 Set the potentiometer to the decried value
 Place an object (or person) at the limit distance.
 Turn the potentiometer clockwise, starting at the left,
 Until the LED shines bright.
 Turn it back slowly until the LED dims.
 Now the limit is set to the correct distance.
 After 5 minutes the potentiometer value is stored and
can only change by repeating Figure 13.

 A power off in the teach mode loses the value and a
new teach process is requested
 A power off after 5 minutes in the teach mode the value
is stored and the sensor starts to work with the latest
stored value by the next power up.

T type (Teach-in)

The T type features a teach-in function that can be initiated
in two ways:
1. Exchange of the polarity of the supply voltage (brown
wire to GND and blue wire to U
With the exchanged connection of GND and U
is put into a setting mode and learns the distance to the
background. The status LED starts to blink. To indicate that
the calibration is finished, the sensor stops blinking and
stays red for about 30 s. Now the wiring of the TOF/Spot-S
has to be adjusted according to the electrical connections
(brown wire to U
The mode is an endless loop of 30 s setting time (blinking
LED) followed by a 30 s break (red LED). In this mode, the
sensor cannot work.
