INSTALLATION MANUAL ENGLISH
RRME 1 and RME1 BT are two single-channel inductive loop detectors. By using microprocessor and surface-mount
technology, a great many features can be integrated into a small space. RME 1 and RME1 BT are compatible with
most commercially available single-channel detectors and are easy to set and install.
Typical applications in the parking and access control environments are safety loops, arming loops and entry or exit
loops.
Standard features of the detector are :
- Reset Switch.
Pressing the reset switch enables the detector to be manually reset during commissioning and testing. This
results in the detector re-tuning the sensing loop and becoming ready for vehicle detection.
- Switch selectable Sensitivity.
The detect sensitivity is the minimum change in inductance required to produce a detect output. (%L/L)
Eight sensitivity settings are available on the switches to allow exibility in conguration.
1 High - 0.01% 5 - 0.2%
2 - 0.02% 6 - 0.5%
3 - 0.05% 7 - 1%
4 - 0.1% 8 Low - 2%
- Switch selectable Frequency.
The frequency of the loop is determined by the inductance of the loop and the frequency switch setting. If the
frequency switch is on, the frequency is reduced. It may be necessary to change the frequency to prevent cross-
talk between adjacent loops.
- Sensitivity Boost.
This feature sets the undetect level to maximum sensitivity and is used to prevent loss of detection of high-bed
vehicles.
- Filter Option.
This option is used to provide a delay of 2 Seconds between detection of the vehicle and switching of the output
relay. This delay is normally used to prevent false detection of small or fast moving objects.
- Permanent Presence Option.
This feature ensures detection of the vehicle will be maintained when the vehicle is parked over the loop for
extended periods.
- Selectable Extend Time.
When switched on this feature extends the outputs for 2 Seconds.
- Pulse Relay Selection.
The Pulse relay may be congured to energise on detection of a vehicle or when the vehicle leaves the loop.
- Selectable Pulse Time.
This feature sets the length of time that the pulse relay will be energised for. 1 Second or 0.2 Second.
- Power Indicator.
This LED Indicator illuminates when power is present.
- Detect Indicator.
This LED Indicator is illuminated when there is a vehicle over the loop or the loop is faulty. This LED can also be
used to determine the loop frequency. On reset, count the number of times the LED ashes. Multiply this num-
ber by 10KHz.For example: if the LED ashes 6 times, then the loop frequency is between 60KHz and 70KHz.
- Loop Fault Indicator.
This LED Indicator is illuminated when the loop is either open circuit or short circuit and is used to give a visual
indication of a faulty loop.

DIAGNOSTICS:
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. (PINS 1 and 2)
The DETECT LED ashes
erratically.
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.
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 randomly
stays on.
Faulty loop or loop feeder wi-
ring.
Movement of the loop in the
ground.
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.
The LOOP FAULT LED is
ashing.
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 cir-
cuit then the inductance is to small and more
turns of wire should be added to the loop.
The LOOP FAULT LED is per-
manently 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 ). If the loop inductan-
ce is to large then try reducing the number of
turns.

INSTALLATION GUIDE:
1. The detector should be installed in a waterproof housing as close to the loop as possible.
2. The loop and feeder should be made from insulated copper wire with a minimum cross-sectional area of 1.5mm2.
The feeder should be twisted with at least 20 turns per metre. Joints in the wire are not recommended and must
be soldered and made waterproof. Faulty joints could lead to incorrect operation of the detector. Feeders which
may pick up electrical noise should use screened cable, with the screen earthed at the detector.
3. The loop should be either square or rectangular in shape with a minimum distance of 1 metre between opposite
sides. Normally 3 turns of wire are used in the loop. Large loops with a circumference of greater than 10 metres
should use 2 turns while small loops with a circumference of less than 6 metres should use 4 turns. When two
loops are used in close proximity to each other it is recommended that 3 turns are used in one and 4 turns in the
other to prevent cross-talk.
4. Cross-talk is a term used to describe the interference between two adjacent loops. To avoid incorrect operation
of the detector, the loops should be at least 2 metres apart and on dierent frequency settings.
5. For loop installation, slots should be cut in the road using a masonry cutting tool. A 45o cut should be made
across the corners to prevent damage to the wire on the corners. The slot should be about 4mm wide and 30mm
to 50mm deep. Remember to extend the slot from one of the corners to the road-side to accommodate the
feeder.
6. Best results are obtained when a single length of wire is used with no joints. This may be achieved by running
the wire from the detector to the loop, around the loop for 3 turns and then back to the detector. The feeder
portion of the wire is then twisted. Remember that twisting the feeder will shorten its length, so ensure a long
enough feeder wire is used.
7. After the loop and feeder wires have been placed in the slot, the slot is lled with an epoxy compound or bitu-
men ller.
