The sensor must be installed and operated only by authorized persons. After the unit is switched
on, the unit starts an automatic self-test. Operation via three plastic film keys is menu-driven.
These keys must not be touched with hard objects!
Flow rate [l/min] 0.04... 10 0.1... 25 0.16... 40 0.4... 100 0.68... 170

switching mode of the two outputs. In case of overflow of the volume amount the decimal point at
the bottom right will be flashing.

9 Error display
If an error is recognized during the self-test or during operation, this is signalled by the (yellow)
flashing alarm LED (AL).
The error can be read out in the menu.
