6.1.3 Calibration
EachtimetheE680boardispowered,theintegratedloopdetector
performsacalibrationoftheconnectedloops.Therefore,youcan
performcalibrationbycuttingoffpowertotheboardforatleast10
secondsandthenreconnectingit.
Fromthebarrier status display, youcanpress, at any time, + to
calibratetheloopconnectedtotheLOOP1inputor+ to calibrate
theloopconnectedtotheLOOP2input.
CalibrationishighlightedbytheboarddiagnosticsbyashingLEDs
DL3andDL4,andwhencalibrationiscompleted,theywillindicate
theloopdetectionstatus,ifconnected.
Theothersignalsprovidedbytheboarddiagnosticsaredescribed
inthefollowingtable:

If one or both magnetic loops are not installed, the loop
detector, following a rst attempt to calibrate, will keep
the status LEDs ashing every 5 seconds (as shown in
the above table)

6.1.4 Adjusting sensitivity
Byadjustingthesensitivityoftheloopdetector,youdeterminethe
variationofinductivity,foreachchannel,thatavehiclemustcausein
ordertoactivatethecorrespondingdetectoroutput.
Sensitivity is adjusted separately for each channel using the two
parameters S1 and S2inBasicconguration
6.1.5 Making the loops
Theloopmustbelaidatleast15cmfromfixedmetalobjects,atleast
50cmfrommovingmetalobjectsandnomorethan5cmfromthe
surfaceofthefinalpaving.
Usea standard unipolar cable measuring 1.5mm²in diameter (if
the cable is laid below ground level directly, it must have double
insulation).Makeapreferablysquareorrectangularloopbypreparing
aPVCcableductorbytracingthepaving,asshowninfigure16(the
cornersmustbecutata45°angletoavoidcablebreaks).Laythe
cableusingthenumberofwindingsshowninthetable.Thetwoends
ofthecablemustbetwistedtogether(atleast20timespermetre)
fromthelooptotheE680board.Avoidsplicingacable(ifnecessary,
weldtheconductorsandsealthespliceusingaheat-shrinkingsheath)
and keep it separate from the mains power lines.

6.2 Expert Conguration
EXPERTconfigurationisusedonlyintheeventthatoperationlogicscustomisationisalreadystored.
Before making changes at this level, be certain that the steps you wish to change and their effect on the automated
system are fully understood.
Changing the third-level parameters involves indicating the
CU value on the LO parameter of the rst-level programming
ToaccessEXPERTconfiguration,press F and, holding it, press + for approximately 10 seconds.
TheuseofF,+ and -inthismenuisthesameasintheothertwoprogramminglevels
