Page 18: Sensitivity Adjustment
CAUTION: It is important to carefully test the application before the system is put into operation. Setting the sensitivity too high or too low, can lead to unexpected behaviour of the application. Rev.00 - 03.2019 | LDP2PA2BU24-7-8 Loop Detector | © 2019 | CARLO GAVAZZI Industri... -
Page 19: Automatic Sensitivity Boost (Asb)
Note: It is generally recommended to only use the ASB function for applications where high bed vehicles needs to be detected. For detection of passenger cars, vans etc. best detection is usually achieved with ASB OFF. Rev.00 - 03.2019 | LDP2PA2BU24-7-8 Loop Detector | © 2019 | CARLO GAVAZZI Industri... -
Page 20: Fail Safe And Fail Secure Mode
Note: If power is returned to the product while a vehicle car is parked on top of the loop, the Loop Detector will not activate. Only a new vehicle entry will generate an activation.
