Fault – Cause – Remedy
Alarm messages in the alarm display field are displayed in hierarchical order.
For example, if two faults are detected at the same time, the more critical of the two is displayed.
The priority level of the alarm messages is identified by exclamation marks:
Warning = !!! Message with top priority
Caution = !! Message with medium priority
Advisory = ! Message with low priority
Savina displays a message for your guidance in the information line when certain alarm messages occur.
The messages are listed in the table in alphabetical order.
In the event of an alarm, this table is designed to enable you to identify the cause and take rapid
corrective action.
