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.
New Action Description of sensor setup

New sensor Factory settings
Install the sensor in the application -
Connect the sensor electrical. White wire to (+) supply -
Power ON
Self-Teach: Red LED blinking
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.

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.

Installation Hints
Dimensions
Relief of cable strain
Protection of the sensing face Switch mounted on mobile carrierTo avoid interference from inductive voltage/
current peaks, separate the prox. switch power cables from any other power cables, e.g.
motor, contactor or solenoid cables
Not correct
Correct
The cable should not be pulled
A proximity switch should not serve as
mechanical stop
Any repetitive flexing of the
cable should be avoided
