Wiring Diagram

The PNP- or NPN-load will automatically
be detected.

Always connect the white wire to (+) supply
for running mode (Locked setup)

Installation

First time calibration

Install and wire the sensor according to the above wiring
diagram. Remember to connect the white wire, the 4th wire,
to (+) supply
The very first time the sensor is powered up, the sensor will

automatically adapt to the surroundings and calculate an
optimal sensitivity by itself – no matter what kind of plastic
material to be detected.
As long as the white wire is connected to (+) supply, the
sensor will be locked and be in running mode.

The sensor is now in running mode

Locked sensor set-up

No other adjustment is needed. As long as the white wire is
connected to (+) supply, the set-up of the sensor is locked,
and will not change during another power down/up.

No Self-Teach. The sensor is now in running
mode

Re-calibration of the sensor

If needed, a new Self-Teach can be activated by discon­necting the white wire from (+) supply, and then connect it
again to (+) supply.

You have now activated a new Self-Teach and the sensor
will now re-calibrate and calculate a new sensitivity accord­ing to the application. Be sure that the application is empty
– no object to detect.
