Dosing timeout monitoring
The dosing timeout monitoring checks whether the dosing procedure has been finished within
the configured Duration time (menu item 2.5.5.7.2 for Recipe 1). If the duration time is
exceeded, an alarm will be triggered, see Fault codes and corrective actions (Page 171).

This function can detect a valve malfunction (non-closure) caused by a blockage, wear, etc.
