NUMBER OF TURNS OF WIRE IN THE SENSING LOOP
• Perimeter of sensing loop
• Perimeter of sensing loop
• Perimeter of sensing loop
In the event two loops are set alongside each other, use 3 turns of wire in one and 4 in the
other to avoid possible crosstalk.
Please be advised that there should be no joints in the wire used for the loop.
POSITION OF DETECTION DEVICE AND INSTALLATION
• Install the device in a watertight box.
• The detection device must be installed as near to the sensing loop as possible.
LOOP DETECTOR SETUP
Select the functions on the 9-way DIP switch.
Turn on power: after 5 seconds, the unit will beep and the red DL1 status LED will start flash-
ing.
The device will beep for the first 10 detections

detection boost option ACTIVE: when a truck is detected by the loop,
sensitivity is increased to its maximum level to detect trailers that are
high off the ground
detection boost option NOT ACTIVE
PERMANENT PRESENCE mode: the relay stays on for as long as the
vehicle is detected by the sensing loop. Once the vehicle leaves the
detection area, the relay goes off.
LIMITED PRESENCE mode: the relay activates when a vehicle is de-
tected and stays in this state for up to 30 min. If the vehicle fails to leave
the detection zone, a buzzer sounds after 25 minutes to indicate that
the relay will go off in another 5 min.
ACTIVATE ON EXIT mode: The relay activates when the vehicle (or
metal object) leaves the detection area.
ACTIVATE ON ENTRY mode: the relay activates when the vehicle (or
metal object) is detected.
