FREQUENCY SELECTOR
OPTION 1 - 2 : Select the detector working frequency
OFF - OFF - Maximum frequency of oscillation
OFF - ON - Mid-Maximum frequency of oscillation
ON - OFF - Mid-Minimum frequency of oscillation
ON - ON - Minimum frequency of oscillation.
ACTION SELECTOR
OPTION 1 - 2 : Select the action to cause by the detector
OFF - OFF - No action
OFF - ON - 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.
ON - OFF - Activate controller open function when vehicle is
being detected
ON - ON - Option not implemented
LED INDICATOR
There are 2 leds, one Red an one Green, indicating the follow function
condition
GREEN RED
ON ON Readjusting
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.
Instruction Manual
1 Loop
Card designed to detect the pass of vehicles.
The card is powered when is inserted into the connector.

Loop
Entry into the detector loop is protected against over voltage.

CARD INSTALLATION
Readjust
Before proceeding with the installation of the card unplug the supply voltage.
button
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.
FUNCTIONING
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.
Input pulse
Presence
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.
CONDITIONS TO BE TAKEN INTO ACCOUNT
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).
