Optex Virtual Loop - Close Range Sensitivity; Side Approach Detection; Side Approach Detection on; Vibration Sensitivity

-26-
This parameter adjusts the sesitivity of close range 100-500mm (4-20 in.) from sensor when a
vehicle enters the detection area. The vehicle detection capability (close range) and the false
detection avoidance capability have the relationship shown in the figure below.

This function could be used only for 90 degree setting. And it could enhance the sensitivity for a
vehicle which approaches from side. This setting is a duration when the sensitivity is enhanced.
The sensitivity enhanced time and the false detection avoidance capability have the relationship
shown in the figure below.
This may need to be changed if:
• This needs to be increased : Even though there is a vehicle, it is not kept detecting.
• This needs to be decreased : False detection due to rain or snow occurs or tailgating
happens a lot.

Side approach detection
This parameter adjusts the ability to kept detecting when a vehicle is detected.The capability to
keep detecting vehicles in the detection area and the capability to avoid false detection due to
rain, snow, tailgating and etc. have the relationship shown in the figure below.
Ingeneral, even with EV creating some vibration, so this function could enhance the sensitivity
for the vibration.
