No standard conformity in case of improper project planning
The air flow monitoring should be set to
≤20 % to achieve project planning
that complies with AS ISO 7240.
NOTE
Always record the type of calibration (air pressure-dependent or -
independent) and, if applicable, the values of height above sea level, air
pressure, temperature and voltage set in the test record (see chapter
"Appendix").
TIP
► Tighten the PVC transition screw connections.
8.9 Checking the air flow sensor calibration
Air pressure-dependent
calibration
The air flow value is checked using the diagnostic software. This shows the
tolerance range of the selected trigger threshold as well as the actual and
target values. The limits correspond to the preset air flow range.
The current air flow value may deviate from the target value not only due to
a fault in the pipe system (breakage or blockage), but also due to air
pressure fluctuations in the surrounding area.
► Check the deviation of the actual value from the target value.
► Make sure that there is a deviation of > ±3/4 of the set trigger threshold.
► The pipe system should be checked as a preventive measure (see the
section "Rectifying air flow faults" in this chapter).
In order to ensure fault-free long-term operation of the unit, the air flow
sensor must be calibrated depending on the air pressure (see chapters
"Commissioning" and "Calibration of air flow sensor"). Only with this type of
calibration are slight air pressure fluctuations still within the monitoring
window and therefore in the permissible tolerance range.
