INSTALLATION MANUAL
POSSIBLE CAUSE
No power supply voltage on the
input.
There may be a poor connection
in the loop or loop feeder. The
detector may be experiencing
crosstalk vith the loop of an adja-
cent detector.
Faulty loop or loop feeder wi-
ring.
Movement of the loop in the
ground.
The loop inductance is to small
or the loop is short circuit.
The loop inductance is to large or
the loop is open circuit.

SOLUTION
Check that the power supply is correctly wired
to the detector. (PINS 1 and 2)
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.
Check the wiring. Tighten screw terminals.
Check for pinched or bent wires. Is the feeder
wire twisted?
Check for cracks in the road surface near the
loop.
Check that there is no short circuit on the loop
feeder wiring or the loop. If there is no short cir-
cuit then the inductance is to small and more
turns of wire should be added to the loop.
Check that there is electrical continuity on the
loop. This can be done using a multimeter on
3
the ohms range (< 5 Ω). If the loop inductan-
11
ce is to large then try reducing the number of
turns.
