1. LAB 9 magnetic loop
The LAB 9 magnetic loop operated detector is controlled by a micropro-
cessor, and its task is to detect the passage or the presence of vehicles
in parking lots, factories, etc.
2. Technical data
Power supply:
24 V
Absorption:
60 mA max.
OUT1:
N.O. relay impulse output 0.5A / 24 V
OUT2:
N.C. relay presence output 0.5A / 24 V
OUT3:
relay exchange output 0.5A / 24 V
Impulse outputs activation time: 1 s
Operating frequency:
from 20kHz to 80 kHz
Temperature:
from -20° C - +55° C
3. Creation and installation of the loop
Create the loop by means of a 1.5 mm²
/(AWG 16) unipolar cord (not
supplied by us).
Loop [A] should be secured firmly to the ground and can be laid under-
ground at a maximum depth of 50 mm, as indicated in the example of fig. 3.
The dimensions of the loop are indicated in fig. 2 and in tab. 3. The total
length of the loops should be from 15 to 30 m.
The loop have to be designed in such a way that the current always flows
in the same direction (clockwise and counter-clockwise), as show by the
arrows in fig. 4, 5, 6 and 8.
The complete loop must be at least 5 m. If possibel, the single-pole wires
should be transposed with each other.
WARNING. If two LAB 9 detectors are to be installed, the loops should
be separated by at least 2 m one from the other to prevent interference,
and DIPs 1 and 2 should be set to different frequencies.
If a grid or metal plate is present under the loop, it might be necessary
to increase the total length of the loop 1 or 2 times.
4. Installation examples
In fig. 2 the magnetic loop is used as an open control (impulse OUT1, or
presence OUT3).
In fig. 7 the magnetic loop is divided into two equal sections so as to obtain
the open control (OUT1 when the vehicle enters the loop) and the close
control (OUT3 when the vehicle exits the loop). Warning: the distance [D]
between the two loop sections should be shorter than the length of the
vehicles that are transiting.
5. Wiring
- Insert the LAB 9 detector card into the appropriate seat AUX inside
the control panel, or use
the CONT1 card-holding base.
- Connect the loop to the terminals of the LAB 9 detector card.
- If LAB 9 detector is inserted inside a controls/radio card seat, the
OUT1 impulse output (N.O.) is connected to the open control (1-3).
To disable the OUT1 output, position DIP8 to OFF.
- If LAB 9 detector is inserted inside a safety card seat, the OUT2 vehicle
presence output (N.C.) is connected to the reversal safety card (1-8).

7. Starting
- Set the operating frequency by means of DIP1 and DIP2, as indicated
in ch.6.
- It is advisable to set DIP5=ON to automatically increase the sensitivity
of the magnetic loop once it has detected a vehicle.
WARNING:if the vehicles occupy the magnetic loop for a long time, set
DIP5=OFF.
- Set a low initial sensitivity value (DIP3=ON and DIP4=ON).
- Power the LAB 9 card and press the RESET button to calibrate the
magnetic card (the LED flashes and then turns off after the calibration
has terminated).
WARNING: during calibration, make sure there is no metal mass above
the loop.
If the DIPs are changed, the RESET button must be pressed again.
- Carry out some tests with transiting vehicles and check for the
correct activation of the outputs (with the lighting up of the LED). If
necessary, increase the sensitivity of the magnetic loop by means of
DIP3 and DIP4.
WARNING You are advised to set low sensitivity values.
- Select the working mode of output OUT3 by means of DIP6.
- Select the impulsed operation of output OUT3 by means of DIP7.
- Activate or deactivate output OUT1 by means of DIP8.
- Set the presence detection duration by means of DIP10.
