Parameter SettingNFM 600 - rev. 02 / 10.07.2019 page 109The individual settings are explained in greater detail in chapter “37.3.3 Digital Inputs”:44 Parameter Menu AlertThe alert menu includes up to eight subsections: >Flow<, >Velocity<, >Water Temperature<,>Battery (12V)<, >Analog Input 1<, >Analog Input 2<, >Analog Input 3< and >Digital Input<.All subsections can be viewed only as soon as the analog and digital inputs have been previ-ously assigned to a type under >Application< and hence have been activated (see chapters“37.3.1 Analog Inputs” and “37.3.3 Digital Inputs”).Details on alarm management, alarm messages, alarm overview, status in-formation etc. going beyond this instruction manual, can be found also in theNIVUS Web Portal handbook.44.1 Menu >Alert< / >Flow<Fig. 44-1 FlowThe >Flow< subsection permits to specify up to five different limit values by using the “+” and“-” keys in >Upper threshold Entries< and in >Lower threshold Entries< each of which isused to trigger an alarm e-mail.Define the threshold values by clicking the fields and by entering numerical values. Themeasurement transmitter will sort the specified threshold values in decreasing order. This ismade independent from the input sequence.In >Hysteresis (abs.)< and >Hysteresis (rel.)< values can be specified by clicking and typ-ing. The measurement transmitter evaluates both values and sends an e-mail on reachingthe highest top limit (highest possible value) and the lowest bottom value (lowest possiblevalue). This mail includes the information that the alert is cancelled.Default settings:Hysteresis (abs.): values and units depend on the language settings previously adjustedHysteresis (rel.): 5.0 %Alarm-E-Mail in case of defective flow velocity sensorIf you wish to receive an alert in case of a defective flow velocity sensor via e-mail check>Alert on error< under “44.3 Menu >Alert< / >Water temperature<“.This setting is not adjusted in the “Flow” section here since the transmitter does not distin-guish between “invalid” and “Error” during detection.
