SENSITIVE
INDUCTIVE
LOOP DECTOR
1. Introduction
The FLUX SA is a single channel stand-alone inductive loop detector
designed for vehicle access applications.
The detector is responsive, highly sensitive, and utilises sophisticated
software algorithms which adapt to prevent false triggering due to
changing environmental conditions. Easy to use dipswitches, as well as
visual and audible feedback of loop operation, ensure a hassle-free
installation experience.
Typical uses include free-exit loops, safety loops, closing loops for
traffic barriers, arming loops for access control equipment, and
general vehicle sensing applications.
IMPORTANT
Safety Instructions
1. All installation, repair, and service work to this product must be
carried out by a suitably qualified person.
2. Do not in any way modify the components of the system.
3. Do not install this product near sensitive electrical components
(e.g. the DOSS sensor inside a CENTSYS gate operator
housing).
4. Do not install the equipment in an explosive atmosphere: The
presence of flammable gas or fumes is a serious danger to safety.
5. Before attempting any work on the system, cut electrical power
and disconnect the batteries.
6. Do not leave packing materials (plastic, polystyrene, etc.) within
reach of children, as such materials are potential sources of
danger.
7. Dispose of all waste products like packaging materials, etc.,
according to local regulations.
8. CENTSYS does not accept any liability caused by improper
use of the product, or for use other than that for which
the system was intended.
9. This product was designed and built strictly for the use indicated
in this documentation. Any other use, not expressly indicated
here, could compromise the service life/operation of the product
and/or be a source of danger.
10. Anything not expressly specified in these instructions is not
permitted.

4. Standard features of the detector
Pressing the reset button enables the detector to be
manually reset at any time. This results in the
Reset Button
detector re-tuning the sensing loop and becoming
ready for vehicle detection. In addition, a 0.5s
output pulse will be generated.
Dipswitches
If this switch is ON, the detector is in Run Mode, and
functions normally. If OFF, the detector halts, and
Run Switch the output relay defaults to the detected state. This
is useful when working on a traffic barrier, as it will
prevent the barrier from lowering.
The frequency of the loop is determined by the
inductance of the loop and the frequency switch
Frequency
setting. If the frequency switch is on, the frequency

is reduced by approximately 25%. It may be
Switch
necessary to change the frequency to prevent cross-
talk between adjacent loops.

If pulsed output is selected, this switch configures

This switch enables a delay of two seconds between
detection of the vehicle and switching of the output.
Filter Switch
This delay is normally used to prevent false
detection of fast-moving objects.
This option increases the sensitivity of the detector

after initial detection of a vehicle. This is useful to

reliably detect vehicle and trailer combinations.
Boost (ASB)
Sensitivity returns to the selected value once the
Switch
vehicle has been undetected.
If selected together with Presence Output, the
output will remain active as long as a vehicle
remains on the loop. The danger of using this
setting is that any change in the environment (for
Permanent
Presence example the introduction of metal into the vicinity
Switch of the loop) will not automatically be tuned out
without pressing the reset button. If not selected,
the loop will automatically tune out any permanent
detection after five minutes.

Power
This red LED is on when power is present, and the
Indicator LED
controller is functioning.
This red LED is illuminated when there is a loop
Loop Fault fault. If the loop is open circuit, the Fault LED will

remain on.
These five red LEDs provide a visual indication of
the Detection Level. Once all five LEDs are on, the
Detection
detection threshold is almost reached. This is a very

LEDs perform reliably. With no vehicle in the vicinity, all
the LEDs should be off.
