Optex Virtual Loop - Presence Detection Timer; Relay Response Time; Slide Gate Cancellation

-28-
This parameter adjusts the recognition time of the sensor.
The respose time and the false detection avoidance capability have the relation shown in the
figure below. Also it effects for human cancellation capability.
This may need to be changed if:
• This needs to be increased : Pedestrians are sometimes detected.
• This needs to be decreased : Sometimes a vehicle is not detected.
Higher speed vehicle is not detected.
NOTE
The presence detection timer starts calibration regularly, regardless of the detection status.
This prevents continuing false detection by the sensor when the ambient condition changes.
This may need to be changed if:
• This needs to be increased : Vehicles are prone to stay long in the detection area.
• This needs to be decreased : The sensor is kept detected by some ambient condition.

Presence detection timer
This parameter adjusts the function to prevent false detection when a slide gate closes. By
setting it On, the sensor could ignore the closing slide gate more. If it sets to On, a vehicle
entering to slide gate with some angle might not be detected more.
