BFT RME 1 Instructions D'installation page 7

RRME and RME 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 and RME 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. (%ΔL/L)
Eight sensitivity settings are available on the switches to allow flexibility in configuration.

- 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 (only for RME/BT 1).
This feature sets the undetect level to maximum sensitivity and is used to prevent loss of detection of high-bed
vehicles.
- Filter Option (only for RME/BT 1).
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 configured 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.
- Direction Logic (only for RME/BT 2).
This feature enables the detector to give a pulse output on relay1 for a vehicle travelling from loop1 to loop2 and a pulse
output on relay2 for a vehicle travelling from loop2 to loop1. To enable this feature switches 2 and 4 must be
on.
- 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 flashes. Multiply this num-
ber by 10KHz.For example: if the LED flashes 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.
