Proportional/constant pumpdrivenbyacurrentsignal.
Settingtheswitchonconstant position,thepumphasflowcontrol(frontpanelknobmaybeset
from0%to100%ofpumpnominalcapacity).Flowcontroliselectronicallysetanditoperatesonpump
injectionsnumber.Toavoidlinearityproblemdonotsettheknobofpumpflowbetween0%and10%.
Settingtheswitchontheproportional position,thepumpcapacityissetproportionallytoanalog
currentinputsignal;asignalchangewillbefollowedbyalinearchangeofpump’scapacity.
Thecurrentrangeis0÷20mA(0dosing,20maxdosing).
Themaximumpumpcapacityformaximuminputsignalissetbythe%markedknob.
TheFICpumpcanbecontrolledbyanyelectronicdevice(suchaspH-meter,redox-meter,etc)that
hasananalogcurrentsignaloutput.Thissignalmustbeappliedtothebipolarcableprovidedwiththe
pump,usingthefollowingconnections:
-Redwire:positive (+)
-Blackwire:negative (-)
