If the “Masking” function has been set (see paragraph
2.13 System options

1.5 AUTOMATIC FAILURE DISPLAYING
When a system failure occurs, the keyboard buzzers will ring immediately, and the reason for signalling will appear
on the displays. Moreover, all the outputs programmed as “Failure” will be actuated. Since a failure may affect
correct operation of the system, these signals take priority over any other type of signal found on the display. In the
event that several types of failure occur, the individual signals will be displayed again and again by turns.
The writings on the display will disappear only after all the causes that led to failure signalling are removed. The
buzzer sound can in any case be stopped earlier by pressing key
F
; otherwise, it will stop after 1 minute.
