function for the digital outputs or 'Failure signal' for the analog output) (see menu items 4.1.2,
4.2.1 and 4.3.1).
• A flashing "F" process related error at the top right of the display indicates a process error.
• A flashing "D" at the top right of the display indicates a device error.
Should errors in groups 'F' and 'D' occur at the same time, only 'D' will flash.
In communication via PROFIBUS, the diagnostic message displayed here is also reported under
the extended diagnosis with the diagnostic bit "EXTENSION_AVAILABLE".

For texts with more than 16 characters, the marks
device display respectively indicate that there are other characters to the left and/or right of the

Electrode check (Menu item 2.2)
The electrode DC voltage is scanned cyclically when this menu item has been selected. This
detects e.g. deposits on the electrodes. If there is a fault or an error, the alarm signal 'Flow
measurement unreliable' is triggered.
Note
This function requires a sensor with SmartPLUG.
Empty Pipe Det. (menu item 2.3)
The function checks whether the electrodes of the sensor are wetted by the medium. To do this,
you have to determine the monitoring interval.
