Instruction Manual
Card designed to detect the pass of vehicles.
The card is powered when is inserted into the connector.
Entry into the detector loop is protected against over voltage.
Automatic readjustment.

Activate controller security function when the vehicle
is being detected.If you use it, you must remove the
C.SEG jumper connector of the controller.
In another security system is used you must connect
it in serial.

INTERMIT OFF
Loop is too short or its broken.
If the loop its not broken, try selecting a low
frequency or readjusting the detector
OFF
INTERMIT
Loop is too long or there are too many turns
in the loop.Try selecting a higher frequency
or readjusting the detector.
OFF
ON
Vehicle detected.

CONDITIONS TO BE TAKEN INTO ACCOUNT
TERMINAL DESCRIPTION
Before proceeding with the installation of the card unplug the supply voltage.
Insert the card into the indicated card connector (Card detector or a similar name)
Detector should be installed as close as possible to the loop and the connection must be made with twisted cable.
By powering the manoeuvres box, the detector will automatically enter into adjustment process.
The magnetic detector sensor loop generates a magnetic field that is altered by a sudden change caused by the proximity of a metallic
mass (vehicle) that impinges on it. This change in the magnetic field causes the detection of the vehicle, invoking an action accordingly.

A vehicle detection invoke two actions ( if are allowed), generate an input pulse (i.e.: to open a door) and a presence signal during the
detection over the loop.
Red Led indicates a vehicle is detected.
The readjusting button is used to readjust the detector to any changes that may be occurred around or over the loop and that can affect
it. The detector enter into readjustment mode automatically when its power connected, but pressing the button you can cause an
adjustment whenever is necessary.
When two different loop detectors are close, the magnetic field of one interferes on the other. To avoid this phenomenon selects a
different frequency of oscillation in each individual detector and put the loops as far as possible (minimum 1 meter).
