Depending on the planning process - with or without the “ASD PipeFlow” calculation software - the following setting procedure
is required:

Warning
Switch settings W01 to W44 may be used only after consulting with the manufacturer. The airflow monitoring val-
ues stored under those switch positions are not tested in accordance with EN.
The description of the predefined positions and the operator structure is found in Sec. 4.4.4.3, 4.4.4.4, 7.2.1 and 0.
Depending on the use of the ASD 532, it may be necessary to make adjustments to the airflow monitoring using the
“ASD Config” configuration software. These adjustments relate merely to the size of the monitoring window (pipe break-
age/pipe blockage) and the fault delay time (time until the exceeded monitoring window is reported as a fault). Please note and
adhere to the following information:
Warning
•
Increasing the LS-Ü values ( > ±20% / > 300 s ) means exceeding the normed EN 54-20 range and should be
used only after consulting with the manufacturer.
•
The window size ±20% should in principle not be undershot . Smaller window sizes may be set only if, at the
same time, the delay time of the airflow monitoring is increased to at least 10 min . Due to the very high sensi-
tivity of the airflow monitoring when the window size is below ±20% and the delay time is ≤ 300 s, the risk of
false alarms due to airflow monitoring faults increases accordingly.
Notice
•
In applications with high levels of air turbulence, it may be necessary in some instances to increase the delay
time and the window size to over ±20
% . Important : This means that norm EN 54-20 is no longer complied
with and should only be used after consultation with the manufacturer.
•
Changing the configuration “ Airflow pipe blockage / pipe breakage On/Off ” is for use under special condi-
tions and may be implemented only after consulting with the manufacturer.
