5.1 - Operating principle of the relays
The factory setting establishes that both relays function according to the principle of standby current. The
operation principle of the relay can be set according to the following table by using jumpers, if tted on the
card. In this regard, the housing of the detector must be opened carefully (see table 7).
- Warning! On the card there are components which are sensitive to static energy. When
working with the device open, appropriate precautions are required. Do not touch the compo-
nents or conductors! The warranty will be nullied for damages caused by improper handling!

5.2 - LED indicators
The green LED indicates that the detector is ready for operation. The red LED, depending on the occupa-
tion status of the loop, indicates the activation of the relay output (see table 8).

5.3 - Loop frequency indication
About 1 s after the adjustment of the detector, the loop frequency is indicated by ashing signals on the
green LED. First of all, the 10 kHz location of the frequency value will be displayed. For each frequency
value of 10 kHz, the green LED of the detector channel will ash once. After 1 sec. the 1 kHz position will
be displayed in the same manner. If the value at the position of 1 kHz is ‘0’ the LED will ash 10 times.
The 1 kHz position ashes are slightly shorter than the 10 kHz position ashes.

3 - FUNCTIONAL SPECIFICATIONS
The inductive loops detector LP22 is a system used for detecting vehicles by
means of inductive loops with the following characteristics:
• Evaluation of two loops
• Presence detection or directional detection
• Galvanic isolation between loop and electronic parts of the detector
• Automatic adjustment of the system after power up
• Continuous balancing of frequency drift
• Suitable for monitoring individual parking spaces
• No interference between loop 1 and 2 due to multiplexing.
• Sensitivity can be set regardless of the loop inductivity
• Occupied loop message reported by the LED indicator
• 0V Relay contacts which serve as outputs
• Operating principle of the 2-channel relay with switchable jumper
• Indication of the loop frequency via LED
• Loop connection available for Diagnostics
In the design and installation of inductive loops, you
should take into consideration the table opposite.
A normal insulated copper wire, preferably with a
cross-section of 1.5 mm2, can be used to create the
loop.
Lay the cable,with the number of windings indicated
in the table. The two cable ends must be intertwined
(at least 20 times per meter) from the loop to the
detector.

4 - PROGRAMMING
4.1 - Sensitivity
The sensitivity setting determines for each channel the change in inductivity that a vehicle must cause in
order to use the output of the detector.
The sensitivity setting is performed separately for each channel using the 2 DIP Switches (see table 1).
Table 1
Sensitivity level Channel 1: DIP Switch 1 and 2
Channel 2: DIP Switch 3 and 4
1 low (0.64 % Δf/f)
2 (0.16 % Δf/f)
3 (0.04 % Δf/f)
4 high (0.01 % Δ f/f)
4.2 - Frequency setting
The operating frequency of the detector can be adjusted in 2 levels by using the DIP Switch 5 (see table 2).
Table 2
Frequency DIP Switch 5
Low
High
The permitted frequency range is between 30 kHz and 130 kHz. The frequency depends on the chosen
frequency level, and the inductivity resulting from the geometry of the loop, the number of loops and the
power supply line of the loop.
4.3 - Wait time and new adjustment
The hold time can be adjusted with DIP-switch 6. At the completion of hold time it will be displayed “free
loop” and the detector calibrates automatically. The hold time starts with the occupation of the loop.
Table 3

5 '
5 '/

A new adjustment can be activated manually by changing the delay time.
When switching on the power supply voltage, the detector will adjust the loop frequency. If there are brief
outages in voltage (< 0.1 s), no new adjustment will take place.
4.4 - Output function
• Presence detection
For presence detection, the DIP Switch 7 must be positioned to the left. In this position, by means of
the relay 1 the presence on loop 1 is reported. With the DIP Switch 8, the output signal for the relay 2 is
determined (see table 4).
Table 4
Output function DIP Switch 7 - DIP Switch 8
Both channels perform presence detection
Channel 1 presence det.
Channel 2 output pulse
• Directional detection
If DIP Switch 7 is in the right position, two directional logics will be supported depending on the DIP Switch
8 (see table 5).
Table 5
Output function DIP Switch 7 - DIP Switch 8
Direction presence signal
Direction pulse output
The directional pulse is mainly used for counting systems, while the presence direction signal is used for
door and barrier control systems.
The examples in table 6 explain the operation modes of the direction logics. The direction signal is sent
via the relay of the rst loop to be crossed, i.e. in the driving direction 1➟ 2 the signalling is done via the
relay 1.

The direction signal in the opposite direction is generated in the
same way.
In case of breakage or closure of a loop the operation switches to
the “Presence detection” mode, until the fault has been xed.
Through the relay of the loop channel without faults, the signal of
presence is now emitted if the loop is occupied.
