Description and intended use

Induction loop detectors such as traffic detectors are electronic sensors for inductive detection of metallic objects. Using induction loops, for example, vehicles are detected, and depending on the device, their design and direction of movement. The traffic detectors are operated in combination with various induction loops and electronic controllers, such as frequency converters or PLC controllers. The areas of application are, for example, the detection, monitoring and counting of vehicles in the areas of traffic engineering, door and barrier controller, parking and tunnel monitoring as well as traffic light systems.

Product characteristics

The traffic detectors have the following properties:

• 1 loop channel (single-channel variants) or 2 loop channels (dual-channel vari- ants)
• 2 potential-free relay outputs with changeover contact (R24 variants)
• 4 open collector outputs (O24 variants)
• 8-pole DIP switch for configuration
• 4-pole DIP switch for advanced configuration
• 2 or 4 LEDs for the indication of detector and loop states
• USB interface for diagnostics and advanced configuration
• Connection for power supply (AC/DC)
• Galvanic isolation between loops and electronics
• Automatic adjustment of the device after switch-on
• Continuous adjustment of frequency drifts to suppress environmental influences
• Sensitivity independent of loop inductance
• Fixed hold times regardless of the loop coverage
• Direction detection based on two loop channels (dual-channel variants)
• Multiplexing prevents mutual interferences of the loop channels (dual-channel variants)
• Compact plastic housing for mounting on DIN rail in control cabinet

Vehicle detection

Whether a metallic object is located in the loop area is identified via an LC oscillator (electrical oscillatory circuit). The channel output is switched according to the output function configured.

Output signals

Depending on the output configuration, presence, pulse or direction signals or direction logics as well as loop faults are output. For the pulse signal, it is also possible to select whether an output should occur when a loop is driven past or vacated. In addition to inversion of the output signal, both outputs can individually be permanently switched on or off.

Alignment of the loop channels

When the detector is switched on or the reset button on the front is pressed for one second, an alignment of the loop channels is run. If there has been an interruption of power, an automatic alignment only takes place if the operating voltage has been interrupted for at least 0.5 seconds. Alignment takes around one second if no vehicles drive over the loop in this time. External influences on the loop frequency may result in longer alignment times, and their causes must be determined and eliminated.

Scanning of the loop channels

The dual-channel traffic detector can evaluate two loop channels. The timed scanning of the loops is carried out in multiplex mode. They are connected to the common oscillatory circuit oscillator over a multiplexer. This prevents the loops interfering with each other. The connected induction loops are switched on and off in rapid succession. Current is only ever supplied to one loop at a time. This means that both loops can be operated at the same frequency. The cycle time of a scan in multiplex mode is 12 ms.

Loop error detection

Loop closure and loop break are identified as loop errors. If no induction loop is connected to the loop channel, this corresponds to a loop break error status. Once a loop error has been detected, the loop channel switches off. This may cause the available operating modes to be restricted, for example direction detection. When one loop channel is switched off by the Detector Tool, this does not affect the second, connected loop channel (2 channel versions).

Electrical connections

In the following section, the connections for the inputs and outputs are described.

Power supply

The detector can be operated with direct or alternating current , according to the requirements for Safety Extra-Low Voltages (SELV) of Protection Class III.

Note the permitted power supply Comply with the technical data and safety instructions!

The power supply is connected to the blue terminal block.

Power supply connection (blue)

Loop inputs

Up to two analogue inputs for the induction loops on the terminal block are located on the underside of the traffic detector. The terminal block is either 2-pole or 4-pole, depending on the product variant.

The induction loops are connected to the orange terminal blocks as shown in the illustration.

L2a Induction loop channel 2 connections
L2b (dual-channel variants)

Loop connections (orange)

Signal outputs

The open collector outputs are primarily intended for applications with high switching rates and low output power, e.g. PLC controller. Each signal output can be inverted. In this case, when the power supply is turned on, normally open contacts function as normally closed contacts, and vice versa. This happens by switching between open circuit and closed circuit principle. Loop faults can also be interpreted as loop covered or as loop free.

Status| Normally closed contact (NC)| Normally open contact (NO)
---|---|---
Not inverted (open circuit)| Inverted (closed circuit)| Not inverted (open circuit)| Inverted (closed circuit
 Voltage off| | | |
Detector ready loop free| | | |
Loop covered| | | |
Loop failure| (loop covered by default configurable as loop free with Detector Tool)

Switching states of the signal outputs

Relay outputs with changeover contact

The relay outputs are designed as changeover contacts. This allows the contacts to be connected as normally closed (NC) or as normally open (NO) contacts. The relays are potential-free and suitable for many different switching modes.

The analogue outputs of the (R24) relay variants are connected to the red and yellow terminal blocks as shown in the following illustration.

NO1 Normally open contact to output 1 or output 2 NO2
COM1 Common contact to output 1 or output 2 COM2
NC1 Normally closed contact to output 1 or output 2  **NC2

Assembly and electrical installation

In the following section, assembly and electrical installation are described.

NOTE Illustrations and technical data on the device can be found on the illustrations and technical data on the housing and connections in the sections at the beginning of this document.

Setting up the magnetic loop

Realisation of the loop

Use a flexible cable with section 1,5 mm2 Insofar as possible, the loop must have a shape like it is shown in the picture below.

The number of turns depends on the perimeter (P):

The minimum clearance between two loop cables is 65 cm. The closest loop cable of a retractable bollard (distance at the axis) or of any mobile metal object is 80 cm

In case that a current line passes close to a loop, it is appropriate that it observes a minimum distance of the loop with respect to the path of the electrical cable:

Loop tail:
Each installation loop has its own loop tail; it is impossible to bind several loops to a detector with a common loop tail
A loop tail cannot exceed 150 metres (length of the cable).

Realisation of the loop tail (Lc)

Lc < 10 m

Starting from the loop corner until the detector bollard, keep the same cable and twist the two wires along the entire length of the loop tail with a minimum of 12 twists per metre

10 m < Lc < 150 m

Make the actual loop by meeting the instructions of paragraph (Realisation of the loop). At the loop corner make a splice between the loop cable (VGV1.52) and the shielded cable (Use a shielded cable of the Belden type for the loop tail). Weld the conductor wires among them (wire to wire welding). Insulate the thus manufactured loop to the detector and connect the braid of the cable to the earthing.

Functional test:

Once positioned, proceed with the following measures and check compliance with the following parameters:

Insulation resistance with the respect to earthing (measure with the help of an insula- tor voltmeter)| > 5 MOhm
Internal resistance of the loop and of the loop tail (measure with the help of a multimeter)| < 20 Ohm

NOTE:
LED position The LEDs for loop channel 1 are located at the top or side of the device, while loop channel 2 are in the middle.

Adjusting sensitivity (switch-on threshold)

The switch-on threshold can be selected in 255 increments in the range between 0.01% and 2.55% f/f. The higher the switch-on threshold, the lower is the sensitivity for signal activation.

Typical settings

• Generally speaking, sensitivity is adjusted in large steps, and the switch-on thresh- old selected is not greater than 640.
• Switch-on thresholds of over 640 and fine tuning may not be required for differ- entiation between vehicles. It is possible to differentiate, for example, buses with large loops (e.g. 10.0 m x 2.5 m) and correspondingly high threshold values (>1000)

NOTE
Minimising interference factors:
In order to minimise interference factors, the sensitivity should be as low as possible, i.e. the value of the switch on threshold should be as high as possible.
