16.4.12 External demand using a 0 to 10V signal
Thecontrollercanrequestademandforthemaximumowsetpoint(withboost,ifneedbe)
byissuingananalog0to10Vsignalforexternaldemand.Forthispurpose,the0to10V
output is used as an alternative to issuing the control signal.
Analog or binary demand processing can be integrated into the analog request for an exter-
nal demand.

16.4.13 Creep feed rate limitation with a binary input
It is possible to report to the controller when the creep feed rate has fallen below a certain
levelbyusingalimitswitchoftheprimaryvalveconnectedtotheterminals04/12ortoin-
putRüF1.Eithertheopen(BI=0)orclosedbinaryinput(BI=1)canbeconguredattermi-
nals04/12toindicatethatthecreepfeedratehasfallenbelowacertainlevel.Onlythe
closed binary input at RüF1 can be processed. Shortly after the alert, the controller closes the
valveRk1.Assoonastheowtemperaturefallsbelowthesetpointbymorethan5°Cafter
the valve has been closed, control operation is started again.
