Display And Cancellation Of Alarms And Warnings; Event Log (History) - Salda MCB Technical Manual

5.13. DISPLAY AND CANCELLATION OF ALARMS AND WARNINGS

The system notifies the user about the system failures by warnings that are canceled automatically and by alarms that have to be canceled man-
ually. The latter are recommended to be canceled by a specialist prior to finding out the causes of the alarm. Information on alarms and warnings
is also displayed in the main window ADJUSTER › VENTILATION CONTROL. If at least one alarm is active, the system is shut down and external failure
indication is activated. Alarms and warnings can be reviewed and canceled in the window ADJUSTER › ALARMS or USER › ALERT. All possible alarms
and warnings are provided in the table below.
