TOF/Spot
6.1

P type (Preset)

The P type needs no configuration; a specific detection
range is factory set according customer request. Due to
the preset value, the P type is a pure plug-and-play sensor.

C type (Automatic calibration)

The C type cannot be manually calibrated. The sensor
calibrates the background every time it starts up. The C
type has to be fully installed and implemented into the
application before connecting it to the controller.
Functionality:
Every time the sensor starts up (power-up), the TOF/Spot
learns the background information anew during the first 30
s after start-up (the start-up time increases by 30 s). If the
sensor has no background (e.g. it doesn't "see" anything) at
start-up, the switching distance is set to 6 m (20 ft).
Important:
 When there is a background, be aware that the set
switching distance is always set about 150 mm (5.9 in)
less than the distance to the background or the object
used for calibration.
 A background is used to calibrate the sensor. If there
is none, an object has to be used for simulating the
background during the distance setting or the sensor
calibrates to the maximal range.
6.3

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, use Figure 12 as the
settings are not printed on the sensor. Take a small screw
driver and turn the potentiometer to the required position.

Figure 12: Example of an adjustment between 0.2 m and 3 m
Preset:
 Set the potentiometer to the limit value before the
sensor is mounted.
Teach:
 Mount the sensor at its final position.
 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.

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
has to be adjusted according to the electrical connections
(brown wire to U and blue wire to GND).
SP
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.
