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.

SYMPTOM
PROBABLE CAUSE
CORRECT ACTION
The loop detector will not work
The green LED is off
There is no power supply to the loop
detector
Check power supply
The loop detector will not work
The red LED is flashing slowly
(0.5 Hz)
The corresponding loop is shorted
Check the loop cable
The loop detector will not work
The red LED blinks at either 1Hz or
2Hz
The frequency of oscillation falls
outside the allowed range
Adjust frequency with dip switches
or change loop turns
The loop LED is detecting properly but
the contact is not made
Bad connection of the relay contacts
Check relay connections
Dip switches 5 to 8 are not responding
properly
Their function varies according to
dip switch #10 setting

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

A. CABLE SPECIFICATIONS FOR LOOP AND FEEDER
• 1.5mm2 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
Check the appropriate loop mode
required and adjust dip switch #10
• 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
D. DIP SWITCHES
C. DETERMINATION OF THE NUMBER OF LOOP TURNS
After each dip switch change the sensor launches a learning process
WARNING :
For conformity reasons, in any situation, the antenna factor defined as the loop surface multiplied by the number of turns
should not exceed NA = 20
For example, if L=2m, Ea=1m and the number of turns=4, then the NA = 2x1x4 = 8 < 20.
Find hereafter the recommended values for the turns :

< 3 m2

Automatic Sensitivity Boost (ASB option) [recommended for better trucks detection] :
During a detection the sensitivity increases automatically to 8 times the preset sensitivity given by the
sensitivity potentiometer adjustment. It is limited to the maximum sensitivity (Δf = 0.005%).
It goes back to the preset value after detection stops.
Dip Switch #5
Relay A function : presence or pulse (not used with dual loop in combined mode)
Dip Switch #6
Relay A Pulse type : entry or exit (used only at pulse function)
or Relay B mode (with dual loop in combined mode) (see next drawing)
• non-directional :
The relay B provides a pulse according to the dip switches #7 and #8 setting.
• directional A— B :
The relay B provides a pulse only if the loop A is detecting before the Loop B.
The detection takes place according to dip switches #7 and #8 logic.

Warning : During the detection, the 2 loops have to detect simultaneously for a short period to be
able to determine the movement direction. During loop installation make sure the 2 loops are close
enough to each other to ensure a common detection (typical 1m).
