6 DESCRIPTION OF SYSTEM
6.1 General description
ThepositionerType8792/processcontrollerType8793isa

proportionalvalves.Thedeviceincorporatesthemainfunction
groups
     -Positionsensor
-Electro-pneumaticcontrolsystem
-Microprocessorelectronics
Thepositionsensormeasuresthecurrentpositionsofthepropor-
tionalvalve.Themicroprocessorelectronicscontinuouslycompare
thecurrentposition(actualvalue)withaset-pointpositionvalue
speciedviathestandardsignalinputandsuppliestheresultto
thepositioner/processcontroller. If thereisacontroldierence,
theelectro-pneumaticcontrolsystemcorrectstheactualposition
accordingly.

6.2 Designs
6.2.1 Type 8792, positioner
Thepositionoftheactuatorisregulatedaccordingtotheposition
set-point value. The position set-point value is specied by an
externalstandardsignal(orviaeldbus).
6.2.2 Type 8793, process controller
Type8793alsofeaturesaPIDcontrollerwhich,apartfromactual

Theprocesscontrollerislinkedtoacontrolcircuit.Theposition
set-pointvalueofthevalveiscalculatedfromtheprocessset-point
valueandtheactualprocessvalueviathecontrolparameters(PID
