1) GENERAL OUTLINE

The induction detector is an inductive-loop vehicle recognition system.
2) APPLICATIONS
- barrier control devices
- door and gate control devices
- technique for parking and traffic management
3) CHARACTERISTICS
- 230 Vac 50/60 Hz power supply
- Use of two loops
- Galvanic insulation between loop and detector electronics
- Automatic system setting after activation
- Continuous frequency variation resetting to eliminate environment in-
fluences
- Suitable for checking individual car park places
- No interference of loop 1 and loop 2 by means of Multiplex process
- Sensitivity setting independently of loop inductance
- Indication of engagement by means of Led signal
- Dead contacts-relays operating as outputs
- Relay activation which can be converted from dark current mode to input
continuous current mode by means of a switch
- Indication of loop breakage or closure by means of Led
- Indication of loop malfunction occurred and then eliminated
- Indication of base frequency by means of green Led blinking light
- Round 11-pole plug.
4) SETTING OPTIONS
- 2 frequency levels common to both channels
- 4 sensitivity levels for each channel
- Holding time of 5 minute or timeless, common to both channels
- Presence or direction recognition
- Continuous or impulse signal for channel 2 relay
- Continuous direction signal or impulse direction signal
5) SETTINGS
5.1) SENSITIVITY
Sensitivity setting is used to establish which inductance variation a vehicle
must provoke for each channel, in order to set the corresponding detector
output.
The sensitivity value is set by means of 2 dip switches divided into 4 levels
for each channel according to the Dualsystem.
Dip switches 1 and 2 set the values for channel 1 while dip switches 3 and
4 manage channel 2.
Sensitivity level
Dip-switch
1 low (0,64%∆f/f)
2 (0,16%∆f/f)
3 (0,04%∆f/f)
4 high (0,01%∆f/f)
5.2) FREQUENCY
The detector working frequency can be selected in the same way for both
channels over two levels. The allowed frequency range goes from 30kHz to
130kHz. The frequency depends on the geometric shape of the loop, the
number of windings, loop power supply and the switch position selected.
The frequency can be set by means of dip switch 5 for both channels.
Frequency level

low
5.3) HOLDING TIME
The holding time can be set in the same way for both channels by means
of dip switch 6.
Holding time
5 minutes
timeless
Once the holding time is over, the "loop free" message is displayed, and a
new loop resetting carried out automatically. The holding time of one of the
detector channels starts with the engagement of the loop belonging to it.
5.4) EMISSION FUNCTION
5.4.1) PRESENCE RECOGNITION
To detect any presence, move dip switch 7 to the OFF position. In this mode, dip
switch 8 is used to determine the emission signal for the relay on channel 2.
For channel 1, a continuous signal is always emitted by relay 1.

5.4.2) DIRECTION RECOGNITION
With dip switch 7 in the ON position, two direction logics are supported in rela-
tion to dip switch 8. The direction impulse is mainly applied to systems involving

counting functions, whereas the continuous direction signal is required for door
or barrier operation devices.
The example of loops 1 and 2 with drive direction 1
logic operation method. The direction signal is emitted by the relay of the loop
which is activated first. This means that in case of drive direction 1
indication is given by relay 1.

cates vehicle reversing.
In case of reverse drive direction, the drive signal is determined in the same way. In
case of loop breakage and/or closure, the presence recognition mode is activated
while the malfunction lasts.The continuous signal is emitted on loop engagement
by means of the relay of the channel which is left operating.
5.5 RESETTING
When the power supply is connected, the detector automatically carries out a
setting. In case of short power cuts <0.3s, there is no resetting; the existing con-
ditions remain unaltered, i.e. with power supply on. Resetting can obviously be
carried out manually by operating the reset key. The setting time is about 1s with
stable loop frequency.In the case where, during setting, a loop becomes engaged,
the setting time is lengthened accordingly. In the case where the loop becomes
permanently engaged during the setting process, the detector is reset as soon as
the vehicle leaves the loop. This allows the following vehicles to be recognised. In
case of prolonged setting times, the loop frequency is unstable. If necessary, the
loop/detector system must be inspected to detect any malfunctions.
