Loop Detector GLDS:(this loop detector has two models: black and red color)
Features:
1) Reset Switch: The reset switch enables the detector to be manually reset during commissioning and testing . This results in the detector re-tuning the sensing loop and becoming ready for vehicle detection;
2) Selectable Pulse Time: This feature sets the length of time that the pulse relay will be energized for 1 Second or 0.5 Seconds;
3) Pulse Relay Selection: The Pulse Relay may be configured to energize on detection of a vehicle or when the vehicle leaves the loop ;
4) Sensitivity Boost : This feature sets the un-detecting level to maximum sensitivity and is used to prevent loss of detection of high-bed vehicles ;
5) Switch Selectable Sensibility : 4 sensitivity setting are available on the switches to allow flexibility in configuration ;
6) Switch Selectable Frequency : 4 frequency settings are available to prevent cross-talk between adjacent loops ;
7) Filter Option : This option is used to provide a delay between detection of the vehicle and switching of the output relay . This relay is normally used to prevent false detection of small or fast moving objects ;
8) Permanent Presence Option: This feature ensure detection of the vehicle will be maintained when the vehicle is parked over the loop for extended periods .
