1. INTRODUCTION
The electricalcontrolboxtowhichthismanual referscan beused toregulateandmanage
automaticdistribution unitsconsisting ofelectromagneticindustrialvibratorsthathavea
maximumintakethat isnot greaterthanthatindicated on theratingplateonthebox.It hasin
factbeen conceivedforcontrol systemsusingmodulesthatarealsodifferentfromone
anotheranddialogue.
Inalltheavailableversionstheboxinquestion is stabilised inasmuchasthecircuit(EL7_ST,
EL7_PLC, EL7_AC, EL7_AC_PLC)isnotonlystableintermsof temperatureandreliablebut
isalsoequipped withfeaturesthatenableittocompensateanylinevariations(±20)thus
keepingconstanttheintensityofvibrationsregardless ofthefluctuationstowhichthenetwork
issubjected overthespaceoftwenty-fourhours.Thisfeatureisunalteredbyanytypeof
powersupply.
The EL7.AC and EL7.AC.PLC aretheversionswithvibration sensors.Thecircuitsthatthey
contain(EL7_AC or EL7_AC_PLC)notonlyenablelinevoltagevariationstobestabilised but
alsostabilisethe weightvariations withwhichthevibratorisloaded.
The versions EL7.SE, EL7.AC.SE, EL7.PLC.SE and EL7.AC.PLC.SE consistoftwocircuits,
oneforactual regulation ofthevibrator(EL7_ST, EL7_AC, EL7_PLC and EL7_AC_PLC)and
theotherformanagingtime(SE).
2. GENERAL INSTRUCTIONS
Beforeconnectingthecontrol boxtothepowersupply,makesurethatthepowersupplyis
compatiblewiththeratingplatevalues.
The control boxmustbeused onlyforthepurposesforwhichithasbeendesigned,i.e.for
controllinganelectromagneticvibrator.Anyotheruseisimproperandthereforehazardous.
The manufacturercannotbeheldresponsibleforanyimproper,incorrectorunreasonableuse.
Intheeventof faultsand/ormalfunctionsof theappliance,switchitoff and donottamperwith
it. Foranyrepairs,contactonlyTUMAC,whichwill useoriginal spareparts.Failuretocomply
withtheseinstructionsmayjeopardisethesafetyoftheappliance.
Anyadjustment, measurementorcheckthatisrequired must becarriedout byauthorised and
qualified personnel.Themanufactureracceptsnoliabilityforharmtopersons,animalsor
thingscaused byinterventionstothecontrolbox byunauthorised andunqualified personnel.
WARNING
Donotusetheappliancenearzonessubjecttovibrationsorindampand/oracid

−vibratortoclamps5-6;
−earthtoclamps3-4.
IncompliancewiththeEMCstandard,thecardisequipped withafilterwithleakage

•Setting minimumandmaximumvibratorspeed
The vibrator’sminimumand maximumspeedscan beseteitheronlybyapotentiometer
command(versions:EL7_STandEL7_AC)orbyapotentiometerand PLCcommand
(versions:EL7_PLCandEL7_AC_PLC);inthelattercasetheselection mustbemadeby
jumperY4asshownin thefig. (disconnectpowersupplybeforemaking the
selection).
−Setting speed bypotentiometercommand
Settingminimumspeed:
Turntominimumthespeed-adjustmentknob(100Kpotentiometer) locatedon the
lidofthebox,thenadjust theminimumTRIMMERuntiltherequired minimumspeed
isreached.
Settingmaximumspeed:
Turntomaximumthespeed-adjustmentknob (100Kpotentiometer)) located on the
lidofthebox,thenadjustthemaximumTRIMMERuntil therequired maximum
speed isreached.
−Setting speed throughPLCcommand
Speedcanbeset byconnectingan externalsignal comingfromthePLCthatvaries
from0-10Vtoinputs2and3of theconnector2orbyconnectingan external signal
varyingfrom0-20mAtoinputs1and3oftheconnector2.
Payattentionto+and -polarities
Settingminimumspeed:
Transmittheexternal minimumsignal andadjusttheminimumTRIMMERuntil the
requiredminimumspeedisreached.
Settingmaximumspeed:
Transmittheexternal maximumsignal andadjustthemaximum(automatic)
TRIMMERuntil therequired maximumspeedisreached.
•Variation ofinitial ramptime
Initial ramptimecan bechanged:
−slow1second
−fast0.1seconds
bymeansofjumperY2asinthefig. (disconnectpowersupplybeforemaking the
selection).
•Switchingcontrol boxON-OFF
The vibratorcan beswitched off usingtheconnector2inthefollowing manner:
connecttheinputs3-5oftheconnector2withacleancontactthatcarriesnovoltage
(e.g. relaycontact)orconnectorofinput3-4ofconnector2with24-VDCinputsignal (e.g.
fromPLC).Inthelattercase, payattention to+and –polarity.
Disconnectpowersupplybeforemaking theconnections.
