Thepositionsensorrecordsthecurrentposition(POS,actualposition)ofthepneumaticactuator.Theposi-
tionercomparesthisactualpositionwiththeset-pointposition(CMD)speciedasastandardsignal.
Ifthereisacontroldierence(Xd1),thepositionersendsapulsewidthmodulatedvoltagesignaltothe
actuatingsystemasanactuatingvariable.Withsingle-actingactuators,thepressurisingvalveisactuated
viaoutputB1ifthereisapositivecontroldierence.Ifthecontroldierenceisnegative,theexhausting
valve is actuated via output E1.
Inthisway,thepositionoftheactuatorischangeduptocontroldierence0.
Z1 is a disturbance.

IftheSideControlType8635isoperatedasaprocesscontroller,thepositioncontrolbecomesasubor-
dinateauxiliarycontrolloop.Thisresultsincascadecontrol.
Theprocesscontroller(asthemaincontrolloop)isimplementedinthedeviceasaPIDcontroller.Inthis
case,theprocessset-pointvalue(SP)isspeciedastheset-pointvalueandcomparedwiththeprocess
actualvalue(PV).Theprocessactualvalueissuppliedbyasensor.
