5.5. SETUP FOR INTEGRATED LOOP DETECTOR

The 624 BLD is equipped with an integrated metallic mass
detector for induction detection of vehicles.
Features:
• galvanic separation between the electronics of the detector
and of the loop
• automatic alignment of the system immediately after
activation
• continual resetting of frequency drifts
• sensitivity independent of loop inductivity
• regulation of the working frequency of the loops
• message of loop engaged with LED display
• loop status addressable on the OUT 1, OUT 2, OUT 3 and
OUT 4 outputs

CALIBRATION
0 1
Each time the 624 BLD board is powered,
the display shows the automated system
status and the integrated loop detector
calibrates the connected loops. Therefore,
perform a calibration, removing power from
the 624 BLD for at least 5 seconds.
Calibration is shown on the display through
flashing of the two points, as in figure 15.
no
If one or both the magnetic loops are not installed,
the loop detector is continually calibrated without
this creating problems to the functioning of the
board. Therefore, during display of the automated
system status, one or both the decimal points will
flash constantly.
Once calibration has taken place, the decimal points indicate
no

REGULATION OF SENSITIVITY
Regulating the sensitivity determines the variation of the
inductivity, for each channel, which a vehicle must cause to
activate the relative output of the detector.
Regulation of the sensitivity is performed separately for each
channel with the aid of the two
1st programming level. Consult chapter 5.1
REGULATION OF HOLD TIME
The retaining time count starts on engagement of the loop.
If, on expiry of this time, the loop is still engaged, a new
calibration is performed automatically where the presence
of the metallic mass on the loop no longer causes its
engagement. At the end of the new calibration, the loop is
considered "disengaged".
The retaining time can be regulated with the aid of the two
h 1 h2
and parameters at the 2nd programming level.
