Fault indication suppression
If a fault is detected by the system, this results in a programmed response. In addition,
the system saves the appropriate (fault) report (see section System messages). The
message is saved in the memory of the message logbook (in the measuring head)
and can provide the maintenance engineer with information for/when carrying out de­
vice maintenance, if applicable.
The fault indication suppression designates the time period (in seconds) for which the
system will first pause. The system response is then only initiated if the failure still per­
sists after the specified time has expired. This means transient failures can be ignored
without triggering a system response.

This communicates to the system whether purge air sensors and / or fail-safe shutters
are fitted. After installation and connection of the protective device (at the measuring
head/at the reflector) (see section 5.5.4 D-SK AE electrical connection [
}
88] ) the corre­
sponding entry must be made at this point in the device configuration.
Fig. 7.13: Device configuration
The device configuration example shown above indicates that only at the measuring
head is a protective device configured (1), whilst the reflector there is no entry (0).
For use of the protective device the value "1" must be entered for
Purge air
sensor x present
and for fail-safe shutter
x installed
.
If the value "0" is entered for
Purge air sensor x present
, the system shows a
"0" from the purge air flow (but does not report an error). Any fail-safe shutter that is
fitted will therefore not be opened.
If the value "0" is entered for fail-safe shutter
x installed
, the status of the fail-
safe shutter is always "4-shutter closed“ (and no error message is output in this case
either).
