Installation
- The indicator will shine for a few seconds when starting. When an object is detected by the sensor, the indicator lights up.
- Sensitivity potentiometer:
- Fluctuation up and down
- Rotation left and right
- NOTE: Initial setting is 45 degrees by factory. All the parameters above are only for reference, detection height is 2.2M. Detection range will be different because of the making material of door and ground, please adjust the sensitivity by the knob mentioned above. When it is adjusted to 60 degrees, the detection range is the widest, and the door will keep on closed and open all the time.
- Please do the installation in the proper position, installation height within 3.5m. Please arrange hole (mm) on the installation module. And hole (12m) for insetting guide line.
- Please connect the signal cable with the terminal of the automatic door.
- Brown and Yellow cable: AC/DC12V-24V
- Green and White cable: Signal output COM/NO
- Special Note:
- Take the outer cover off and fix the screws.
- Finish the cable connection and get power.
- Please set the detection range and disjunctor accordingly.
- Cover With The Lid
Adjustment (Get on power)
Detection range as below shown:
