Operation Indicators
Upon power-on, the detector enters self-calibration mode with green LED flashing and red LED extinguished for approximately 1 second. No vehicles should be on the loops during calibration. After calibration, the green LED stops flashing and red LED remains extinguished. When a vehicle passes over the loop, the red LED illuminates.
DIP Switch and Wire Jumper Configuration
DIP1 and DIP2 set sensitivity; DIP3 sets presence output time for relay 1; DIP4 configures relay 2 as presence/pulse output; DIP5 sets presence signal output time; DIP6 sets frequency. Jumper wire connected to open end links PIN16 to NO of relay 1, while close end connection links PIN16 to NC of relay 1.
Work Frequency Settings
Users can adjust loop work frequency to prevent cross-talk from adjacent loops or environmental interference. Two frequency styles are available, configured via DIP6.
Sensitivity Adjustment
Sensitivity can be adjusted using DIP1 and DIP2 on the front panel. If vehicles are not detected during testing, increase the sensitivity setting.
Packaging & Shipping
Packaging: Standard exported carton/wooden package, with customized packaging available upon request. Shipping: Typically dispatched within 48 hours after payment confirmation.
