Faulty loop – Open loop or loop frequency below 20Khz:

Fault LED - 3 flashes, 3 sec pause, 3 flashes, 3 sec pause.........this continues until the faulty loop is

corrected and the detector is reset.

Buzzer - 3 beeps, 3 sec pause, 3 beeps, 3 sec pause.......repeats five times and then silences.

■

If the loop circuit is continuous (measure with continuity meter) then increase the loop

frequency by adding more turns of wire.

Faulty loop – Short circuited or loop frequency above 120Khz:

Fault LED – 6 flashes, 3 sec pause, 6 flashes, 3 sec pause - ..........this continues until the faulty loop is

corrected and the detector is reset.

Buzzer – 6 Beeps, 3 sec pause, 6 beeps, 3 sec pause..........repeats 5 times and then silences.

■

If there is no short circuit in the loop circuit then reduce the number wire turns around the

loop to reduce the loop frequency.

Good loop:

All three the Detect LED, Fault LED and the buzzer will beep/flash (count) between 2 and 11

times to indicate the loop frequency.

■

For example; 3 counts x 10Khz = Loop frequency of 30 – 40 KHz.

Buzzer and LED indications after initial power up/reset:

1 sec flashes 1 sec apart

On permanently

3 flashes 3 sec apart

6 flashes 3 sec apart

Tone as long as vehicle

is in loop area

Continuous tone w ith no

vehicle in the loop area

METAL LOOP DETECTOR

1 Count = 10Khz

Detect LED -

No vehicle (metal) detected in loop area.

Vehicle (metal) detected in loop area.

Fault LED -

Loop w ire is open circuit. Use Dip-sw itch 9 after

any corection is made

Loop w ire is short circuited. Use Dip-sw itch 9 after

any corection is made

Buzzer -

Buzzer sounds to confirm the first ten detections

Loose w iring in loop or pow er terminals.

Use Dip-sw itch 9 after any correction is made.
