UL listed equipment for UL 508

A. CABLE SPECIFICATIONS FOR LOOP AND FEEDER

• 1.5mm

cross section area

• Multi-strand cable

• Insulation material : PVC or Silicone

• For the feeder cable, the wire must be twisted at least 15 times by meter

• Feeder for long runs used for foil screened cable is recommended (earth at equipment end only)

• The feeder cable must be firmly fixed to avoid any false detection (max length : 100 m)

• Waterproof cable junction box is required

B. LOOP GEOMETRY

• With two adjacent loops connected to a dual channel sensor, it is possible for

these loops to share a common slot, if so required.

As the channels are multiplexed, no interference will occur

• Avoid large loops or long feeder (max 100 m), the sensitivity will be affected

The MATRIX Digital Inductive Loop Detector range is the ideal solution for parking barrier control, motorized gates and

doors, vehicle access control and industrial control systems.

The MATRIX range is a high performance single or dual channel vehicle detector packaged in a compact housing, the

connection is made with an industrial standard 11-pin round connector.

Six versions listed below are available, single or dual channel, and 3 possibilities for the power supply :

MATRIX-S110 : Single loop detector with 110 to 120 V AC power supply

MATRIX-S220 : Single loop detector with 220 to 240 V AC power supply

MATRIX-S12-24 : Single loop detector with 12 to 24 V AC/DC power supply

MATRIX-D110 : Dual loop detector with 110 to 120 V AC power supply

MATRIX-D220 : Dual loop detector with 220 to 240 V AC power supply

MATRIX-D12-24 : Dual loop detector with 12 to 24 V AC/DC power supply

APPLICATIONS

42-0570-V1 01/08

• 1 Green LED shows when the module is powered

• 2 Red LEDs give

• the corresponding loop detection state in normal situation

• the value of the oscillation frequency measurement or an error message on power ON

In normal situation the red LED stays ON as long as the loop detects any metallic object.

On power ON the sensor measures the oscillation frequency of each loop. The result of this measurement is displayed using

the corresponding red LED. The amount of blinking indicates the tens value of the frequency. For example 4 short flashes

correspond to a frequency between 40 kHz and 49 kHz. After this message the LED goes back to normal display.

If the loop oscillation frequency falls outside the limits set between 20 kHz and 130 kHz the red LED displays an error

message and the sensor activates the corresponding relay. The blinking frequency shows the type of error according to the

next table. The sensor will stay in this state until the problem is cleared and the frequency goes to the right range.

Remark : The sensor launches automatically a learning process if the oscillation frequency changes more than 10% in

comparison with the measurement value.

Loop frequency error LED display

Oscillation frequency too LOW or loop open LED blinking at 1Hz

Oscillation frequency too HIGH LED blinking faster at 2 Hz

Loop shorted or no oscillation LED blinking slower at 0.5 Hz

SYMPTOM

The loop detector will not work

The green LED is off

The loop detector will not work

The red LED is flashing slowly

(0.5 Hz)

The loop detector will not work

The red LED blinks at either 1Hz or

2Hz

The loop LED is detecting properly but

the contact is not made

Dip switches 5 to 8 are not responding

properly

PROBABLE CAUSE

There is no power supply to the loop

detector

The corresponding loop is shorted

The frequency of oscillation falls

outside the allowed range

Bad connection of the relay contacts

Their function varies according to

dip switch #10 setting

CORRECT ACTION

Check power supply

Check the loop cable

Adjust frequency with dip switches

or change loop turns

Check relay connections

Check the appropriate loop mode

required and adjust dip switch #10
