Instruction ManualNivuFlow Mobile 600page 84 NFM 600 - rev. 02 / 10.07.201937.3.4 Digital OutputsThe transmitter is equipped with one digital output.Default setting: output inactiveThe following different functions can be assigned to the digital output.Fig. 37-11 Digital output activation• Sum ImpulsesOutput of flow-proportional sum impulses. Selection/Input Options:Logic: >Normally open< or >Normally closed<Negative sum impulses: check boxQuantity: manual inputDuration: manual input• SamplerIn connection with a sampler provided by the customer it is possible to define the ac-cording cyclic control. Selection/Input Options:Logic: >Normally open< or >Normally closed<Level: manual inputVolume: manual inputDuration: manual input• Limit Contact FlowExceeding the >Threshold on< value will output a digital signal, falling below>Threshold off< will reset the digital signal = hysteresis function to avoid output flutter. Selection/Input Options:Logic: >Normally open< or >Normally closed<Threshold on: manual inputThreshold off: manual inputValue at error: >Off< or >On< or >Hold Value<• Limit Contact VelocityExceeding the >Threshold on< value will output a digital signal, falling below>Threshold off< will reset the digital signal = hysteresis function to avoid output flutter.The calculated average flow velocity (calculated even from multiple paths) is used. Selection/Input Options:Logic: >Normally open< or >Normally closed<Threshold on: manual inputThreshold off: manual inputValue at error: >Off< or >On< or >Hold Value<
