AMenu / parameter DescriptionDiagnosticsMaintenance control Selection of submenu ‘...Maintenance control’ using .Diagnosis Control Selection of submenu ‘...Diagnosis Control’ using .Diagnosis Values Selection of submenu ‘...Diagnosis Values’ using .Simulation Mode Selection of submenu ‘......Simulation Mode’ using .Output Readings Selection of submenu ‘...Output Readings’ using .Diagnostics / Maintenance controlPreset Maint. cycleSets the service interval (0 ... 9999 hours).After the service interval has expired, the corresponding error message "Maintenance interval is reached.Perform maintenance." is set. The setting "0" deactivates the maintenance interval.Maint. Remain. Time Time remaining in the maintenance interval until the error message "Maintenance interval is reached.Perform maintenance." is set.Start New Cycle Resetting of the maintenance interval. The service interval is reset to the value set in ‘Preset Maint. cycle’.Diagnostics / Diagnosis Control DescriptionEmpty Pipe Detector Selection of submenu ‘...Empty Pipe Detector’ using .Noise Check Selection of submenu ‘...Noise Check’ using .Fingerprints Selection of submenu ‘...Fingerprints’ using .Diagnosis IntervalSets the time span between performing the individual diagnostic.The "Empty Pipe Detector" function will be performed in the selected time span (e. g. every 5 seconds).Default setting: 5s.7 OperationParameter descriptionsMenu: DiagnosticsDiagnostics / Diagnosis Control / Empty Pipe DetectorEmpty Pipe DetectorActivate the "Empty Pipe Detector" function (only for sizes ≥ DN 10).An entirely full measuring tube is essential for an accurate measurement. The "Empty Pipe Detector" functiondetects an empty measuring pipe.In the case of an alarm, the current output assumes the status that was defined in the "Input/Output / ...Curr.Out 31 / 32 / Curr. at EPD Alarm" menu, and the pulse output is stopped.Adjust EPThe Empty Pipe Detector function must be adjusted according to the conditions on site. The switchingthreshold is set during the automatic adjustment.Start automatic adjustment of the Empty Pipe Detector function.Manual Adjust EP F.Manually adjust the Empty Pipe Detector function.The value must be modified in such a way that the frequency for empty pipe detection (Detector EP Value) isclose to 2000 Hz.NotePrior to starting the (manual / automatic) adjustment, make sure that:• There is no flow through the flowmeter sensor (close all valves, shut-off devices, etc.)• The flowmeter sensor is completely filled with the fluid to be measured.ThresholdSet the switching threshold for empty pipe detection.The switching threshold is set automatically during automatic adjustment. The switching threshold can bechanged in order to obtain manual fine adjustment.Detector EP ValueDisplay of the frequency for empty pipe detection. If the current value exceeds the defined switchingthreshold, a message appears on the display and an alarm is output via the digital output, if configuredaccordingly.
