SYMPTOM POSSIBLE CAUSE SOLUTION
The POWER LED is not on. No power supply voltage on the input. Check that the power supply is correctly wired to the detector (terminals 1 and 2).
The DETECT LED flashes
erratically. There may be a poor connection in the loop or loop feeder.
The detector may be experiencing crosstalk with the loop of an
adjacent detector. Check all wiring.
Tighten screw terminals.
Check for broken wires.
Try changing frequencies using the frequency switch. Put the detector with the larger loop
onto low frequency and the detector with the smaller loop onto high frequency.
The DETECT LED stays on. Faulty loop or loop feeder wiring, not correctly fixed.
Movement of the loop in the ground. Check the wiring.
Tighten screw terminals.
Check for pinched or bent wires.
Check for cracks in the road surface near the loop.
The LOOP FAULT LED is flashing. The loop inductance is to small or the loop is short circuit. Check that there is no short circuit on the loop feeder wiring or the loop.
If there is no short circuit then the inductance is to small and more turns of wire should be
added to the loop.
The LOOP FAULT LED is
permanently illuminated. The loop inductance is to large or the loop is open circuit. Check that there is electrical continuity on the loop.This can be done using a multimeter on
the ohms range (< 5 Ω).
If the loop inductance is to large then try reducing the number of turns.
