3 Product Description
3.1 Overview
Together with the inductive loops laid beneath the surface, the LC series loop detectors form a
universal sensor system for detecting vehicles. People are not detected. Vehicles that enter the
inductive loop change the resonant frequency. This frequency change is measured and
analyzed by the microprocessor in the LC10 loop detector. The analysis is automatically and
periodically adjusted to the respective loop, ensuring that any changes in the loop inductance
caused by temperature, humidity or component age are automatically compensated for.
The loop detectors are control units that are fully functional without the need for any other
auxiliary equipment once the power supply and an inductive loop have been connected. The
inductive loop laid below the surface forms the inductor of a high-frequency oscillating circuit.
The metal parts of a vehicle that enters or is located in this wired loop cause the frequency of
the oscillation circuit to change. This frequency change is analyzed by the loop detector, and
the outputs, which are zero-potential relay contacts, can switch. The switching outputs are relay
contacts with a high switching power that can directly control contactors, valves and alternating
current motors. The dimensions of the detection area can be adjusted by changing the size and
shape of the inductive loops.

3.2 Use and Application
Possible areas of application for the LC10-* series loop detectors are:
■ Selective vehicle detection
■ Opening impulse sensor for automatic gates and barrier systems
■ Presence checks for vehicles
■ Direction-specific vehicle checks
■ Controlling traffic light and vehicle detection systems
■ Ticket detection in parking garages
■ Managing tasks in automatic conveyor systems

3.3 Indicators and Operating Controls
3.3.1 LC10-1-*
LED indicator
L D signals the allocation state of the loop (Loop allocated = L D On). A fault in the loop due to
a short-circuit or lead breakage and loop inductance outside the permissible range is indicated
by flashing of L D.
D P switches
It is possible to modify frequency, sensitivity and operating mode by using the DIP switch.
Sensitivity
The response sensitivity of the loop detector can be set in three stages by switches 3 and 4.
Frequency switches
The loop frequency can be set in four stages using the switches 1 and 2.
Operating mode switches
The following operating modes can be set with switches 5 and 6:
1L D indicator
2DIP switch
switch 3 switch 4 sensitivity
OFF ON low
ON OFF medium
ON ON high
Table 3.1 In the switch position "OFF", "OFF" the loop evaluation is switched off.
switch 1 switch 2 frequency
OFF OFF basic frequency f
ON OFF f - 10%
OFF ON f - 15%
ON ON f - 20%
Table 3.2 After actuation of the frequency switches 1 and 2 the loop must be readjusted with switches
3 and 4 set to "OFF", "OFF".
switch 7 switch 8 result
OFF - Pulse (0,8 s)when loop is allocated
ON - Pulse (0,8 s) when loop is abandoned
- ON Increased sensitivity (Boost)
Table 3.3 The increased sensitivity (Boost) is used for the detection of vehicles with high body
assemblies, e.g. HGVs.

3.3.2 LC10-2-*
LED indicators
Indications: L Ds 1 and 2 signal the allocation state of the loops (Loop 1 allocated = L D 1 on,
Loop 2 allocated = L D 2 on).
A fault in a loop due to a short-circuit or lead breakage and loop industance outside the
permissible range is indicated by flashing of the respective L D.
D P switches
It is possible to modify frequency, sensitivity and operating mode by using the DIP switch.
Sensitivity
The response sensitivity of the loop detector can be set in three stages using switches 3 and 4
(for loop 1) and switches 5 and 6 (for loop 2).
Frequency switches
The loop frequency can be set in four stages using the switches 1 and 2.
