… is/are recognised when main air flow set x %
Example If the blockage of 2 aspiration apertures out of a total of 5 aspiration
apertures is recognised, then with the help of the diagnosis tool flow
monitoring can be set to ±20 %.
For a project planning according to EN 54-20, the air flow monitoring
has to be adjusted to ≤20 % in either case.
