Setting At Work - BFT RME Manual Del Usuario

RME
In the case of two contiguous coils, keep a minimum distance of at least two metres between each.
Note: The inductive activity and hence the sensitivity of the coil detection system is reduced by the presence of a steel reinforcement
beneath the road surface. Ideally allow for a distance of 150 mm between coil cable and steel reinforcement.
5. WORKING INSTRUCTIONS
5.1 RESET/CALIBRATION push-button
The RESET push-button makes it possible to initialize the RME and automatically acquire the parameters of the loop connected for
correct functioning.
N.B. Making sure that there is no metallic mass on the loop, press the RESET push-button to carry out an automatic calibration of the
detector.
The RESET push-button must be pressed each time the position of one more dip-switches is varied.
5.2 LED (Fig. 3)
- The led is flashing during the self-calibration phase.
- The led turns on when the presence of a metallic body is detected.

5.3 SETTING AT WORK

•
Realize the connections for the undekal socket as shown in Fig. 3 and subsequently insert the detector as shown in the same figure.
•
Set up the frequency through the dip-switches 1 and 2 as shown in Fig. 2. The change of frequency is mainly useful to avoid
interference between two near loops (2-3 mt.); in this last case it is necessary to set up different frequencies. As a general rule the
frequency must be low for large loop and high for small loop.
•
Set up the sensitivity through the dip-switches 3 and 4 as shown in Fig. 2. Setting the sensitivity allow to forbid the detection of
metallic body with little dimensions such as bicycle and motorcycle.
•
Output OUT1 may be active or not through the dip-switch 8 (Fig. 2) and provides an impulsive functioning (100 ms).
Output OUT2 may be set for impulsive (100 ms) functioning with activation on the entrance or on the exit of the loop; otherwise this
output may be set to presence functioning, through the dip-switches 6 and 7 (Fig. 2 ).
•
Be sure that there is no metallic mass on the loop, and press the RESET push-button to carry out an automatic calibration of the
detector.
•
Carry out sensitivity tests with the various types of vehicles that the device must detect. If necessary, vary the setting of dip-switches 3
and 4 until the desired sensitivity level is obtained. It is not advisable to use excessively high sensitivity values.
•
Once the optimal sensitivity level has been established, if necessary enable the BOOST function using dip-switch 5.
