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.
