Calibration
●Calibration function
This function records (memorizes) the background of the detection area without any pedestrians or vehicle
present.
This process makes the sensor detection capability higher and provides stable detection.
If any noticeable changes occur around the detection area (such as construction of a wall or fence), you must
perform the calibration again.
NOTE
● How to Perform Calibration
[1] Verify that within the detection area there is no vehicle, pedestrian, or objects. If anything is present
remove them out of the detection area.
[2] Press and hold the Calibration button on the sensor unit for 2 seconds and verify that the operation
indicator is blinking blue slowly.
The operation indicator blinks for 10 seconds and blinks more quickly for 2 seconds.
The first 10 seconds are preparation of calibration. You must keep the detection area vacant during this period.
The calibration is performed during the 2 seconds quick blinking period.
If a vehicle or pedestrian enter the detection area during calibration, perform the calibration again.
It may take more than 2 seconds for the calibration if the sensor detected a moving object during the
calibration.
If the calibration does not complete, check if there is any pedestrian or moving object (e.g. flag, banner, tall
weed) around the detection area. Remove it, and calibrate again.
[3] When the calibration is complete, the operation indicator turns to a solid green.
● Cancelling Calibration
To cancel calibration, press and hold the Calibration button for 2 seconds again while the operation indicator
is slowly blinking for 10 seconds. (The operation indicator turns to a solid green)
It is not possible to cancel it while the indictor is blinking quickly. Perform the calibration again.
For normal sensor operation, the calibration must be correctly performed.
The following instructions must be observed.
Perform this after sensor installation.
●
It must be performed without vehicle, pedestrians or any other moving objects in the
●
detection area.
If a vehicle or pedestrian enters the detection area during the calibration,
●
perform the calibration again.
If changes are made to the sensor installation height, direction, and/or Maximum
●
Range after the calibration, the calibration has to be performed again.
