＊
When more than two loops are used, please set up different frequencies in order to eliminate the crosstalk.
(4) RESET Button
RESET button can reset the detector. RESET is needed whenever a frequency is changed.

Installation Information
(1) Teflon loop is recommended and the maximum length could reach
500 meter.
(2) Loops should have 3 to 5 rotaries; the remains of the cable need
to have a helix every 15 cm.
(3) Typical saw cut loop installation
：
(4) The more rotaries of a loop, the lower of the frequency.
(5) The appropriate way of the rotation of a loop is 1.0 to 2.0M in
length and 0.8 to 1.2M in width.
(6) The loop should be installed in an area where has no electric
overhead door near by.
(7) Any vehicle with a speed of no more than 120Km/Hr will be
detected.
(8) The specification for both outputs is 110VAC/10A.
(9) Appropriate way to correct a failed detector:
Press “RESET” button.
Check the DETECT and POWER LED
：
If POWER RED LED is dark, check AC power source and fuse (0.5A, inside of the detector).
If DETECT GREEN LED is blinking, the loop may have a short circuit.
If DETECT GREEN LED is blinking very slowly, loop does not have enough rotaries.
If DETECT GREEN LED is blinking very rapidly, loop has too many rotaries.
When loop has not enough rotaries (frequency will also be too high), change DIP switch to low frequency.
When loop has too many rotaries (frequency will also be too low), increase the loop rotaries.
