Example
If blockage of three aspiration apertures of a total of eight aspiration
apertures should be detected, the air flow monitoring setting must be set to
±20% using the diagnostic tool.
5.3.2 Simplified project planning
Simplified project planning is applied in equipment monitoring and in rooms
with small dimensions. The advantage in this project planning is the uniform
diameters of the aspiration apertures.
The specifications from chapter "Project planning guidelines" apply to the
project planning. In addition, the following limit values and diameters of the
aspiration apertures must be observed. Additional accessories (e.g. air filters
or condensate separators) can influence the max. pipe length.
