Runmeisthemethevalverotates.
Pauseme1isthemethevalveisstopped.
Pauseme=0meansthevalverotatesconnually.
Outputtomotorcontactorisconnuous(Pause=0)orintermient/twointervals
controlledbyLI(levelindicator).

Therearetwomodes:
1. Timecontrolisthedefaultmode,thenRun/Pause1/Runetc.IfLIindicateshighthen
Pause2(normallysettoashorterme).ReturntoPause1aertwoRunperiods
withoutLIindicaonhighlevel.SupervisionbyLIandWarningandAlarmdelay.
2. Levelcontrol.Thepurposeoflevelcontrolistomaintainadustlevelabovethe
valve.ItstartstoRunaerPause1andstopswhenLIindicatesalowlevel.IfLInever
indicatesalowlevel,eitherduetocoveredsensor,orbridgingsothedustisnotfed
out,thesupervisionismadebytheLIandtheWarningandAlarmdelay.
EmptyingisalsopossiblewhenmanuallyiniatedinOFFandStandbymode,i.e.,no
