Multiply this number by 10KHz. For example: if the
LED flashes eight times, then the loop frequency is
approximately 80KHz

6. Tips for a successful loop installation
1.
The FLUX SA should be installed in a weatherproof location, such
as the inside of a gate operator, as close to the loop as possible.
2.
The loop and feeder should be constructed from XLPE (cross-
linked polyethylene) insulated multi-stranded copper wire with a
minimum cross-sectional area of 1.5mm . The feeder should be
twisted at a rate of at least 20 turns per metre to improve
reliability (Remember that twisting the feeder will shorten its
length, so ensure a long enough feeder wire is used). Feeders
which may pick up electrical noise should use screened cable,
with the screen earthed at the detector.
3.
Joints in the wire are not recommended, but where required must
be soldered and made waterproof.
Faulty joints will lead to unreliable operation.
4.
The loop should be either square or rectangular in shape with a
minimum distance of 1m between opposite sides.
5.
Two to six turns of wire are typically used in the loop – see table
below.

6.
When two loops are laid in close proximity to each other, it is
recommended that different numbers of turns are used in each
loop to prevent cross-talk.
7.
Cross-talk describes the interference between two adjacent loops,
and can cause reliability issues.
To minimize cross-talk, adjacent loops should be at least two
metres apart, and on different frequency settings
.
8.
The most reliable form of loop is preformed and enclosed in
conduit. This prevents water ingress, and minimizes the effects of
vibration.

9.
Where a pre-formed loop is not practical, slots should be cut into
the road using a masonry cutting tool. A 45 cut should be made
across the corners to prevent damage to the wire on the corners.
2
The slot should be about 4mm wide and 30mm to 50mm deep.
Remember to extend the slot from one of the corners to the
roadside to accommodate the feeder. After the loop and feeder
wires have been placed in the slot, the slot must be filled with an
epoxy compound or bitumen filler.

The housing of the FLUX SA is not weatherproof, and it should not be

obtaining the optimal position.
8. Electrical setup
1. Ensure that all low voltage systems (less than 42.4V) are
suitably protected from damage, by disconnecting all
sources of power such as chargers and batteries before
doing any work.
2. All electrical work must be carried out according to the
requirements of all applicable local electrical codes.(It is
recommended that a licensed electrical contractor perform
such work.)

9. Commissioning the system
1.
With the loop connected, apply power to the FLUX SA.
2.
The red Power LED will light up, and the green Detect LED will
flash until the loop has stabilized, and then turn off.
3.
If the buzzer is enabled, it will sound continuously during this
period.
4.
Once the loop has stabilized, only the red Power LED should be on.
5.
Bring a metal object towards the loop, and the Sense level LEDs
will begin to light up, indicating the detection range of the loop.
6.
Once all five lights have lit up, the unit will enter detect, with the
green Detect LED lit.
7.
If the buzzer is enabled, a variable tone will indicate the sense
level, and change to a continuous tone once the unit has detected.
8.
Configure the desired operational settings using the Dipswitches

Solution
Check that the power supply is
correctly wired to the 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.
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 electrical continuity
on the loop. If the loop inductance is
too large then try reducing the number
of turns.
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 too small and more turns
of wire should be added to the loop.
