Chapter 2.
10.1 Fault display and acknowledgement
If a fault occurs, the background colour of the
main menu turns RED, the collective fault signal is
activated and the "Current alarms" page is dis

played.
A signal is sent to the defined recipient(s) for sys

tems equipped with remote diagnostics.
The fault can be acknowledged on the user inter

face by remote diagnostics.
If the cause of the fault is removed before
acknowledgement, the background colour of the
main menu turns back to white. If the fault per

sists after acknowledgement, the background
colour of the main menu changes to yellow and
the associated fault signal is marked yellow in the
list of alarms.
10.2 History memory for the faults

(first in, first out). Each fault is stored with a time
stamp (date/time of day).
The list of alarms can be viewed on the "Alarm
history" page.
