deviceviaananalogueoradigitaloutput(eldbus).
5.1.2 General operation of the Mass Flow
Controller (MFC)
TheMFCcomprises:

5.3 Operation of an MFM or MFC
sensor
• Theintegratedow-ratesensorsusethethermalmeasurement
process(anemometricandcalorimetric)tomeasurethemass
ow-rate.Themaincomponentsareaheatingresistoranda
temperatureprobe.Thegaswhichpassesthroughthedevice
modiesthetemperaturedierencemeasuredbetweenboth
resistors.
• ThethermalmeasurementprincipleallowstheMFCtocontrol
therequiredmassow-ratecompletelyindependentlyof
thepressureandtemperatureuctuationsintheapplication
concerned.
Thedampingoftheoutputsignalcanbechangedwith
the"MassFlowCommunicator"(seechapter10.1.3).
OntheMFCtypes8710,8711,8713,8715,thetechnology
fortheintegratedsensorrequireslterstobettedupstream

Thecontrolelectronicscomparethemassow-rate(x)measured
by the integrated ow sensor with the mass ow-rate set-point

Thecontroloperatesindependentlyofuctuationsinpressureor
increasesintheowresistancewhichmaybecausedbysoiling
ofthelter.Therapidlyrespondingsolenoidvalveandthesensor

5.4.1 Control electronics
Thecontrolelectronics:
• processthemassow-rateset-pointvaluesandmeasured
values,
• controlthesolenoidvalve.
Set-point value
Theset-pointvalue(w)istransmittedeitherbyananalogue,nor-
malizedinputsignal,ordigitallyviatheserialinterfaceortheeld
businterface.Iftheset-pointvalueissuppliedbyanaloguetrans-
mission,thefollowingassignmentsareapplied:

Forthecontrolofasystemwherequickow-ratechangesarenot
permitted,arampfunctioncanbeactivated.Thesettingsforan
ascendingandadescendingset-pointvaluecanbesetseparately.
Moredetailedinformationontherampfunctionandon
allotherfunctionscanbefoundinthesoftwaredocu-
mentationfortheMFM/MFC.
Control settings
Theinitialcontrolsettingsaresetatthefactory.
• Amplicationfactors:
After start-up, the controller operates with amplication factors
dependent on the loop properties. When the Autotune function
runs,thesearedeterminedautomatically.Thisfunctionenablesthe
controlsettingstobeoptimizedforthesystem'sactualconditions.
• Controldynamicssetting:
Thedevicehasasettingwhichcanchangethecontroldynamics
with the aid of the "Mass Flow Communicator" software (see
chapter10.1.3).Itsextremeeectsare:
1. averyquickadjustmentinwhichovershootsarepos-
sible.Thisenablesthecontrollertorespondimmediatelyto
verylowcontroldeviations,causingthecontroltobevery
turbulent,
2. asloweradjustmenttotherequiredow-rate.Ifthesystemis
lessdynamic,thebehaviorofthecontrollermaybedamped
sothatminoructuationsofthemeasuredvalueorset-point
valueareadjustedslowly.

Zero point shut-o
Azeropointshut-oisintegratedtoensurethesealingfunction
ofthevalve.Thisisactivatedifthefollowingconditionsoccurat
thesametime:
Set-pointvalue<2%of

(withcontrolrange1:50)
and
Measuredvalue<2%of
nominalow-rateQnom(with
controlrange1:50)
Ifthezeropointshut-oisactive,thePWMsignalisset
to0%sothatthevalveiscompletelyclosed.
5.4.2 MFC solenoid valve
ThesolenoidvalveusedforanMFCisadirect-acting,normally
closedsolenoidcontrolvalve.
TheND(nominaldiameter)ofthesolenoidcontrolvalveisdeter-
minedbytherequirednominalow-rateQnom,thepressurecondi-
tionsintheprocessandthedensityoftheoperatinguid.
Ifthedeviceisoperatedwithinthespeciedpressure
range,thesolenoidvalvealsotakesoverthesealing
functiontogetherwiththecontrolfunction.
Limitation:inthecaseofspecial,hardsealmaterials,the
sealfunctioncannotbeensured.Inthiscaseanaddi-
tionalshut-ovalvemayberequired.

7 INSTALLATION AND
COMMISSIONING
7.1 Safety instructions
DANGER
Danger due to high pressure in the installation/device.
▶Beforeworkingontheinstallationordevice,cutthepressure
andventanddrainthepipes.
Risk of injury from electric shocks.
▶Beforeworkingontheinstallationordevice,switchothe
powerandensurethatitcannotbereactivated.
▶Observetheapplicableaccidentprotectionandsafetyregu-
lationsforelectricalequipment!
Danger due to escape of the medium.
▶Observetheapplicableaccidentprotectionandsafetyregu-
lationsrelatingtotheoperatingmediumused.

Installation and commissioning
Type 8700, 8701, 8703, 8705
WARNING
Danger due to nonconforming installation or commissioning.
▶Installationandcommisioningcanonlybecarriedoutby
qualiedandskilledstawiththeappropriatetools.
Risk of injury due to unintentional switch on of power supply
or uncontrolled restarting of the installation.
▶Takeappropriatemeasurestoavoidunintentionalactivation
oftheinstallation.
▶Guaranteeasetorcontrolledrestartingoftheprocesssub-
sequenttoanyinterventiononthedevice.
7.2 Prior to installation
→BeforeinstallingtheMFM/MFC,removedirtfromthepipes
anduidsystemcomponents.
→Connectasuitablelter(≤25µmmeshsize)upstreamto
ensurethattheoperatinguidiskeptclean.
NOTE
• Useapowersupplyunitwithadequatepower.
• Observethemaximumpermittedresidualrippleoftheoper-
atingvoltage.
7.3 Sequence of the steps to be
performed
1. Mechanicalinstallation
2. Fluidinstallation
3. Electricalinstallation
4. Setthedeviceparameters
5. Pressurizethelineswithoperatinguid
6. Flushandcompletelydeaeratethelineswithoperatinguid
atthecalibrationpressure
7.4 Setting the parameters
7.4.1 Setting the bus address
Toensuretrouble-freesetting,resetthedeviceby
switchingothepowersupplytothedevice.
ThebusaddressofthedevicecanbeseteitherviatheBürkertcon-
gurationtool"MassFlowCommunicator"inthe"Views"window
→PROFIBUS/CANopenordirectlyviathemasterbus.
Theaddressmustbereinitializedafterachangeontheslaveand
onthemaster.Itmaybenecessary,dependingonthebus,tosend
acorrespondingtelegram.
