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.
