Malfunction Possiblecauses Correction
Theoutletpressureincreasesduring
zeroflow.
Acomponentisleaking. Performmaintenance.
High‐frequencyfluctuationsattheset
pressure.
Recognizedas:Outletpressurefluctu‐
ation<0.2sec.
Ifthisfluctuationdoesnotdisappearasthe
dischargeincreases,thecausecanbetraced
backtotheinteractionbetweentheprocess
andtheregulator.
Checktheregulatorsettings.
Low‐frequencyfluctuationsattheset
pressure.
Recognizedas:Outletpressurefluctu‐
ation>0.2sec.
Interactionbetweentheprocessandthe
regulator.
Solution1:Checktheregulatorsettings.
Solution2:Ifsolution1doesnotfixtheprob‐
lem,youcantrytoreplacethepilotspringwith
astifferone(sothatyoucansetahigheroutlet
pressure).
Themaintenanceintervalsaretoolong.
Solution3:Anotherpossiblereasonforthe
fluctuationsisincreasedfrictionbetweenthe
regulatingsystem’smovingparts.Thisincludes
factorssuchasthedynamicsealsaginganddirt
accumulatingintheguides,andcanonlybe
detectedbyperformingmaintenanceona
regularbasis.Incertaincases,therewillbean
audibleindicationwhenguidesaresoiledor
unabletomovefreely,i.e.,intheformofnoise.
