SAFETY
PRECAUTIONS
!
• Shut off all power before attempting any wiring procedures.
• Maintain a clean & safe environment.
• Constantly be aware of traffic around the door or gate area.
• Always suspend traffic through the doorway or gate area when performing testing that may result in unexpected
reactions by the door or gate.
• Always check placement of all wiring and components before powering up to insure that moving parts will not catch
any wires and cause damage to equipment.

A . CABLE SPECIFICATIONS FOR LOOP AND FEEDER
•
16 AWG (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 per yard for each cable.
• 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: 330 feet (100 m)).
• Waterproof cable junction box is required.
B. LOOP GEOMETRY
Ea
Eb
C. DETERMINATION OF THE NUMBER OF LOOP TURNS
• Measure the length (L) and width (Ea) of one loop. Multiply these numbers together to determine the
loop surface area. See above drawing.
• For example, if L=10 ft, Ea= 3 ft, then the area = 30 ft2; 4 loop turns are recommended.
Recommended values for the turns:
<32 ft² <3 m² 4
32 – 54 ft² 3 – 5 m² 3
65 – 108 ft² 6 – 10 m² 2
D. SLOT DEPTH
or if L=2m, Ea=1m, then the area = 2 m2 ; 4 loop turns are recommended.
Area Number of turns
L
• When two adjacent loops are 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 330 feet (100 m)], or
else the sensitivity will be affected.
WARNING:
For conformity reasons, in any installation,
the loop surface multiplied by the number of
turns should not exceed 215 (for square
!
feet); 20 (for square meters)

DIPSWITCH
SETTINGS
A 10 position dip switch is located on the front of the Matrix single detector. Dip switch 3, 5, 6, 7, and 8 configure the relay, while
dip switch 9 controls the duration of the pulse when the Matrix is configured for pulse operation, (as opposed to presence).
Configurations are as follows:
Dip Switch 3:
OFF= FAIL-SECURE MODE Relay is NOT energized when power is applied. Relay is energized upon detection only. In this
mode, the N.O. circuit is open, and the N.C. circuit is closed. Thus, if a closed circuit is required upon detection, one must use the
N.O. and COM terminals since they would close upon detection. When the Matrix is NOT powered, it is in the same state as it
would be for non-detection.
ON = FAIL-SAFE MODE Relay is energized as soon as power is applied, and de-energizes upon detection or power loss. In this
mode, upon powering the detector, the N.O. circuit becomes closed, and the N.C. circuit becomes open. Thus, if a closed circuit
is required upon detection, one must use the N.C. and COM terminals, since they would now be OPEN during non-detection, and
would close upon detection. When the Matrix is NOT powered, it is in the same state as it would be for detection.

III. DIP SWITCHES
After each dip switch change the sensor launches a learning process.
Dip Switch #1
Frequency Adjustments of Loop A (see ADJUSTMENTS on the next page)
Dip Switch #2 Frequency Adjustments of Loop A (with single loop) or Loop B (with dual loops)
Dip Switch #3 Relay configuration : active (fail-secure) or passive (fail-safe_ (see above)
Dip Switch #4
Automatic Sensitivity Boost (ASB option) [recommended for improved truck 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
(∆f = 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 drawing on next page)
• Non-Directional :
Relay B provides a pulse according to the dip switches #7 and #8 setting.
• Directional A→B :
Relay B provides a pulse only if loop A is detecting before loop B. The logic
detection takes place according to dip switches #7 and #8.
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 3 feet).
Dip Switch #7 Relay B function : presence or pulse
Or loop selection for relay B pulse : pulse on Loop B or pulse on Loop A (used with dual
loop in combined mode)
Dip Switch #8 Relay B Pulse type : entry or exit (used only at pulse function)
Dip Switch #9 Pulse duration for both relays (used only at pulse function): 100 ms or 500 ms
Dip Switch #10
Dual loop mode : independent or combined A→B (not used with single loop)

Green LED shows when the module is powered;
Red LED gives:
Normally, the red LED stays ON as long as the loop is in a state of detection.
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 number of flashes 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 (20 kHz to 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 error mode until the error is cleared and the frequency goes to the right range.
Remark : The sensor launches automatically a learning process if the oscillation frequency varies more than 10%
in comparison with the measurement value.
• the corresponding loop detection state in normal situation;
• the value of the oscillation frequency measurement or an error message on power ON.
