## **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
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 very first time the sensor is powered up, the sensor will automatically adapt to the surroundings and calculate an

## **Recalibration 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 now be recalibrated and calculate a new sensitivity according to the application. Make surethat the application is empty – no object to detect.
