Detection Sensitivity - Optex ViiK Exposed Type OVS-02GT Series Installation Instructions Manual

9
Advanced Installation (Applied)
The following setting items should be configured if the sensor does not operate as expected
during a system operation check or if an error occurs. These do not need to be set for normal
installation. Change the settings as required using the application.
9-1
Angle
The sensor processes detection responses based on the "Angle" parameter.
Set the "Angle" parameter according to the installation conditions.
9-2
Detection Area Range (Max. Range)
If the detection range is set too long, the sensor may mistakenly detect objects outside of the
detection area. On the other hand, if it is set too short, detection becomes difficult and some
objects may be missed during detection.
9-3

Detection Sensitivity

The detection sensitivity parameter adjusts the susceptibility of detection when a vehicle enters
the detection area.
The detection and human cancellation rates have the relationship shown in the figure below.
In normal cases, use with sensitivity level 4.
9-4
The non-detection sensitivity parameter adjusts the susceptibility to switch to the non-detection
status when a vehicle leaves the space, leaving the space empty.
The detection and human cancellation rates have the relationship shown in the figure below.
In normal cases, use with sensitivity level 4.
