...Maintenance control
Preset Maint. cycle
Sets 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".

Diagnosis Interval
Sets 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.

...Empty Pipe Detector
Empty Pipe Detector
Activate 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" function
detects 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 EP
The Empty Pipe Detector function must be adjusted according to the conditions on site. The switching threshold 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) is close
to 2000 Hz.
NOTE
Prior 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.
Threshold
Set the switching threshold for empty pipe detection.
The switching threshold is set automatically during automatic adjustment. The switching threshold can be changed
in order to obtain manual fine adjustment.
Detector EP Value
Display of the frequency for empty pipe detection. If the current value exceeds the defined switching threshold, a
message appears on the display and an alarm is output via the digital output, if configured accordingly.
