8.4.1 Details on DIP switches
DIP1 and DIP2:
areinterpretedtogether:
DIP1:0=voltage→ DIP2:0=0-10Vor1=2-10V.
DIP1:1=current→ DIP2:0=0-20mAor1=4-20mA.
Attention
Either a voltage source can be connected to the U-terminal or a current
source to the I-terminal. Never connect both at the same time.
DIP3:
DIPswitch3congurestheanalogueoutputsAO1andAO2(seewiringdiagram,Fig.9,page
21
).DIPswitch3denesthescalingofthetwoanalogueoutputs.WhenDIP3=0,AO1is
setto0-10VandAO2to0-20mA(factorysetting),whenDIP3=1,AO1issetto2-10Vand
AO2to4-20mA.InModbusmodeAO1andAO2canbeconguredseparately.
Using 2-10 V / 4-20 mA enables clear identication of a loss of signal (= 0 V / 0 mA).
DIP4:
DIPswitch4changesthedirectionofoperationoftheactuator.
Thedirectionofoperationcanonlybechangediftheunithasbeeninitialized.Untiltheunithas
beeninitialized,thefollowingsettingapplies:Valveclosedwhenactuatorspindleextended.
Therecanalsobenochangeinthedirectionofoperationduringaninitializationrun,whether
ornottheunitwasalreadyinitializedbeforestartingthecurrentinitializationrun.
Thedirectionofoperationmustnotbeconfusedwithheating/cooling!Heatinginstandard
modeiscarriedoutwithDIPswitches7,8and9setto"0".Coolinginstandardmodeis
carriedoutwithDIPswitches7,8and9setto"1".Split-rangecanbecombinedwithheatingin
standardmode,butnotwithcooling.InModbusmode,split-rangecanbecombinedwithboth
heatingandcooling.
DIP5:
Savesthecurrentpositionasswitchingposition"2EZ-1"whenswitchedfrom0to1.No
functionisassignedtoswitchingfrom1to0.EvenifDIP5isleftinposition1whenthe7020A
positionerisswitchedon,thecurrentpositionwillnotbesaved.
DIP6:
Savesthecurrentpositionasswitchingposition"2EZ-2"whenswitchedfrom0to1.No
functionisassignedtoswitchingfrom1to0.EvenifDIP6isleftinposition1whenthe7020A
positionerisswitchedon,thecurrentpositionwillnotbesaved.
DIP7, DIP8 and DIP9:
ThesethreeDIPswitchesworktogethertodenethesplitrangefunctionatanalogueinput2
(AI2).
