air flow fault
If the air flow sensor adjustment has been effected in
dependence on the air pressure and the measured value is not within the
tolerance range of the selected air flow threshold (air flow fault is indicated at
the device), another fault other than those caused by air pressure or
temperature variations is present.
1. In this case check the pipe system for tightness and blockage (refer
to chapter 7.3, section "Trouble Shooting").
If the pipe network has been modified during the trouble shooting, the
original configuration of the pipe network is to be restored after the
completed trouble-shooting and the air flow is to re-adjust.
2. If this check leads to no negative results, check the air flow monitoring by
connecting the test pipe and carrying out the operational check described
in chapter 7.5.2.
If the air flow monitoring is damaged only authorized personnel is allowed to
exchange the detector module!
If the test results do not vary from the given values, it is obvious that the air
flow monitoring has no defect.
3. Carry out a new adjustment for the connected pipe system.
Register the adjustment type (dependent on the air pressure or not) and, if
required, the values of the air pressure, the height above sea level and the
set voltage at MP1 / MP4 in the commissioning protocol.
4. Keep an eye on the current air flow value during maintenance or check it
during the next inspection at the latest.
The diagnostic software allows filing any memorized and current diagnostic
data and the settings of the DIL switch. Rename this file to be able to
compare these data with the newly read-out values during the next check.
For more information about the diagnosis software DIAG 3 refer to
separated documentation.
5. If there is a similar variation from the rated value like before, interfering
environmental influences are the cause for this variation. If these negative
influences on the air flow monitoring cannot be stopped, the next less
sensitive threshold is to be set.
