After initialization, close the 4.2 mm aspiration boring of the test pipe with some duct
tape. After approximately 5 secs, the fault indication on the device must start to flash.
After approximately 35 secs, the fault indication on the device must be permanently
illuminated. The device reports the malfunction "Air flow too low (static evaluation)". The
airflow value is approximately -35%.
Open the 4.2 mm aspiration boring again. After a few seconds, the fault indication on the
FAS-420-TM must stop flashing.
Open the 7.0 mm aspiration boring on the test pipe. After approximately 5 secs, the fault
indication on the device must start to flash. After approximately 35 secs, the fault
indication on the device must be permanently illuminated. The device reports the
malfunction "Air flow too high (static evaluation)". The airflow value is
approximately +85%.
Close the 7.0 mm aspiration boring again. After a few seconds, the fault indication on the
FAS-420-TM must stop flashing.
Remove the test pipe and reconnect the pipe system.
On completion of the functional tests, the original settings must be restored.
The commissioning of the device with the pipe system must be repeated from
Section 6.3 Calibrating the Airflow Sensor.
Once commissioning has been concluded, the set values must be collected and saved
using the FAS-ASD-DIAG Diagnostic Software. A printout of the set values should be
