The Vehicle Loop Detector is designed to detect the presence and passage of vehicles. It features a reset switch that allows manual resetting during commissioning and testing, enabling the detector to re-tune the sensing loop for optimal vehicle detection. Selectable Time: This setting determines the duration the relay remains energized—either 1 second or 0.5 seconds. Relay Configuration: The relay can be set to activate upon vehicle detection or when a vehicle exits the loop. Sensitivity Boost: This function sets the detection sensitivity to maximum level, helping prevent missed detections of high-bed vehicles. Switch-Selectable Sensitivity: Four sensitivity levels are available via switches, providing flexibility in system configuration. Switch-Selectable Frequency: Offers four frequency options to minimize interference between adjacent detection loops. Filter Option: Introduces a delay between vehicle detection and relay activation, helping avoid false triggers from small or fast-moving objects. Permanent Presence Mode: Maintains continuous detection signal when a vehicle remains over the loop for extended periods.
