FREQUENCY
This depends on loop dimensions. Frequency microswitches generate one variation only.
To avoid interference between closely positioned detectors, you should set different frequencies.
In general, the detector connected to the loop with the higher inductance (the larger one with more windings) must be
set to the lower frequency, and vice versa.
SW3 – SW4
SENSITIVITY
This function is for selecting users, i.e. denying access to motorcycles and small vehicles.
SW5
BOOST
This function enables an increase in sensitivity level at detection. When the vehicle moves away from the loop, sensitivity
returns to the selected level. This system makes it possible to maintain the detection contact even for very high vehicles
or when a tractor with trailer passes through.
SW6
FILTER
This is used to prevent rapid transits of metal masses on the loop (e.g.: manoeuvring cars).
If this function is activated when the loop is occupied by a vehicle, the response time is delayed by two seconds.
SW7
PULSE ACTIVATION
Two different pulse activation times can be selected:
• when the magnetic loop is engaged;
• when the magnetic loop is released.
SW8
PRESENCE TIME
To prevent permanent accidental presence of vehicles from disabling the system, by selecting a LIMITED presence time,
the system resets automatically to the new inductive state and, therefore, returns the contact to its initial state.
The presence time of the vehicle enabling the new setting cannot be quantified exactly, because it is closely linked to all
the system's parameters (inductance, sensitivity and frequency). If the above parameters are at average values, the
vehicle presence time causing the new setting is about one hour.
If a PERMANENT presence time is selected, this activates the detection contact unlimitedly for the vehicle's entire
presence time on the loop.
Detector setting is fully automatic when it is powered up.
The detector performs the setting automatically according to the inductance value of any detection loop in the range
from 20 to 1500 microhenry.
While this operation is taking place, there should not be any metal masses on the loop surface.
Any loop inductance variations are, however, compensated by the detector, which automatically sets itself to the new
state.
In any event, you can always press RESET to command a new automatic setting operation.
