Install Detector :
The detector must be installed in a convenient weatherproof location as close to the loop as possible. Installation location must choose to stay away from the heat source, it around other devices must maintain a distance of at least 10mm (mustn’t fix cling to the cabinet). A correct loop configuration and detector installation will ensure a successful inductive loop detection system. Loop of several important parameters include: loop figure, size, and turns, install methods (details as “Loop installation guide”).
Operation and Indication
Whenthe power is applied, the red Power LED will glow and the detector is tuning,the green Check LED blink about 3 seconds. The green LED will also glow whenever a vehicle is detected passing over the inductive loop. If a loop fault
exists the green LED will come on and flash indicating a fault.

Frequency
Thefrequency can be set by the two DIP switch on the circuit board. Disconnect power and then take down the detector from the socket, remove the shell. DIP6 (LA) is used for setting the frequency. ON: working in low frequency. OFF:working in high frequency The detector will be calibrated automatically when connecting the power after adjusting the frequency. Notice: High frequency has been set. The installation distance is too close between the two loop
detectors, the different frequency can be setting by the user.Sensitivity The response sensitivity can be set using the threestage switch on the front. The setting L corresponds to the lowest sensitivity. M is the medium sensitivity and H is the highest sensitivity. After the sensitivity has been set, a reset and a calibration automatically takes place.
Attention If thedetector isn’t working normally, you must check the loop and wiring at first, and then alter the frequency or the sensitivity.
Output Relay
Whenvehicle press loop, the relay's output mode set by the main control panel switch. TLD-410 has two loops, corresponding to two output relays. loop1 (7-8 pin) corresponds to the relay 1 (5, 6, 10 pin) output for the existence of a fixed output signal, the loop 2 (7,9 pin) corresponds to the relay 2 (3,4,11 pin) and pull the output signal from the DIP code switch DIP1, DIP2, DIP3 (SW0,SW1, SW2) decision.ListenRead phonetically.Vehiclepresence check model output setting Vehicle direction (count) check mode output signal and setting:
Reset
Thedetector automatically reset and tune to the inductive loop when the power is applied, whether on initial installation or after any break in power supply.Should it be necessary to retune the detector, as may be required after
changing any of the switches or after moving the detector from one installation to another.
