5 SETUP AND OPERATION
5.1 CONTROLANDFUNCTIONS
Thepumpcanbecontrolledbydisplaypanel,10‐stepswitch,analoginputs,modbusorEthernetconnection.
 Displaypanelcontrolsandoverviewspumpmodes,parametersandon/offstatus,
 10‐stepswitchallowsustochangerelayoutput,analoginputs/outputsandresettingthepumps
communicationconfiguration,
 Analoginputsgiveuscontroloverthepump(start,stop,max.curve,min.curve,0‐10V,4–20mA,…),
 Analogoutputsareusedforgettinganaloginformationaboutthepumpsperformance(errors,speed,
mode,flow,height),
 Relayoutputsignalizespumpsstatus,
 Ethernetconnectionsofferscontroloverallpumpfunctionsandsettings(pumpsvariables,digitalinputs,
erroroverview),
 Modbusconnectiongivesustheoverviewofallparametersandsettings(pumpsvariables,analog
inputs/outputs,erroroverview).

Severalsignalswillinfluencethepumpoperation.Forthisreason,settingshavedifferentprioritiesasshowninthe
tablebelow.Iftwoormorefunctionsareactiveatthesametime,theonewithhighestprioritywilltake
precedence.

InnightmodetheexternalsignalsandModbusstopsignalbecomeactive.Duetothepossibilityofconfusionwe
donotrecommendusingthenightmodewhileusingexternalsignals.
