Sincro HB4 - 2 Intended Use; 3 Introduction; Control of ID Plate; 4 Operating Principle and Characteristics of Voltage Regulation System

2. INTENDED USE
All generators are supplied with a declaration of
incorporation in accordancewith Europeanrules and
regulationsasprovidedinfinalpagesofthismanual.
Furthermoregenerators aresuppliedonthefollowing
basis:
• theyshallbeusedaspowergeneratorsorforrelated
functions;
• theyshallbeusedinoneofthefollowingapplications:
-mobile(withorwithoutcanopy-fortemporarypower
supplies);
-onboard(marineuse);aftercertication
-on commercialvehicles(freight transport /cold
storage,etc.);
-onrollingtrack(auxiliarypower);
-onindustrialvehicles(earthhandling,hoisting,etc.);
-stationaryinstallation(industrial,factory/plant);
-stationaryinstallation(residential,commercialand
lightindustry,house/o󰀩ce/hospital);
-energymanagement(cogeneration,peaksshaving);
-alternativeenergyschemes;
• thestandard generatorsaredesigned tosatisfy
“industrial” electromagnetic emission limits and
immunitystandards.Intheeventthatgeneratorshave
tocomplywithelectromagneticemissionlimitations
forresidential,commercialandlightindustrialzones,
someadditionalaccessoriesmaybenecessary;
• the installation wiringdiagram requiresthat the
generatorhousingisconnectedtotheearthconductor,
usingan adequatelysized cablewith a minimum
lengthpossible;
• theuse ofanysparepartsthatare notgenuineor
notexpresslyauthorisedshallfree Sincro from any
warranty liability and any responsibilityconcerning
conformitytoregulationsandrelevantconsequences;
• installation,aftersales assistanceandmaintenance
mustbecarriedoutbyproperlytrainedsta󰀨witha
knowledgeoftheprovisionsofECdirectives.
3. INTRODUCTION
Ondelivery inspect the generatorto checkit hasnot
been damaged during transport or that no parts are
missing.
3.1 Control of ID plate
ThegeneratorscanbeidentiedbytheirIDplate.The
ID plate must be checked and compared with order
specications.
TheSincro Technical O󰀩ceisalwaysavailablefor
anyclarication.
4. OPERATING PRINCIPLE AND
CHARACTERISTICS OF VOLTAGE
REGULATION SYSTEM
TheBL4-U AVR (AutomaticVoltageRegulator) of HB-
IB series, is supplied by the auxiliary winding. AVR
acts on the exciter stator, directly controlling the field
generatedbythemainrotorbymeansofthesequence
exciterrotor-diodebridge-mainrotor.
Thevoltageregulatorcontrolsandkeepsconstantthe
voltageofonephase.
Alternatively, the generator can be equipped with
a digital regulator type (AVR RD2). The RD2 AVR
regulatorcontrolsandmaintainsconstanttheaverage
voltageofallthreephases.
A frequency control progressively deactivates the
machinewhenthe drive engine speeddrops below a
pre-set,adjustablethreshold,preventingover-excitation
atlowoperatingspeedsandreducingtheloadengage
effectsontheengine.
5. GENERAL MECHANICAL AND
ELECTRICAL SPECIFICATIONS
FOR COUPLING WITH ENGINE
As an independent unit, designed to be built into a
generating set, it is impossible to apply all the signal
decals on the generator during production. These
decals,indicatingapotentialhazardorriskduetolive
componentsaresuppliedlooseandhavetobeapplied
bytheconstructorofthegeneratingset.
Thisgeneratorsaredesignedtooperateatatemperature
between-20°Cand40°Candatamaximumaltitudeof
1000ma.s.l.
Thenominalperformanceindicatedontheplaterefers
tooperationwithinthesetemperatureandaltitudelimits.
ContactSincro Technical Office for operateoutside
theseparameters.
At temperatures over 40°C and/or altitudes above
1000ma.s.l.aderatingshouldbeapplied(seetable).
Forall“UL”generators,don’tconsiderthesedataand
contacttheSincro Technical Office.
Thegeneratorsarefittedwithanairventilationsystem,
protective guards and drip-proof covers; they are not
suitable for outdoor installation unless an adequate
protective shelter is provided. When under storage,
awaitinginstallationorinstandby,itisadvisabletouse
anticondensationheaterstoprotectthewindingsfrom
damp.
Intheeventofinstallationinsideaclosedhousing,make
surethatthecoolingairtemperatureforthegenerator
doesnotriseabovestandard.
The canopy must be constructed so that the engine
airvent inthecanopyisseparatefrom thegenerator
air vent, especially if the air inlet in the canopy has
to be supplied by the cooling fan. What’s more, the
generator air vent should be constructed to prevent
dampfromenteringbyfittingsuitableprotections.The
