System Messages and Alarms
4.1 Alarm Message Types and Priority
There are five categories of messages, as shown below:
Critical error
(highest priority) A fault has occurred and affected much the system performance, so that normal operation
is not possible.
Error (high priority) A fault has occurred and affected the system performance. The fault must be fixed as soon as
possible.
Warning messages (medium priority) An event has happened, which may affect the system performance or cause a
system failure unless no precautions would be taken during a reasonable period of time.
Information messages
(low priority) Messages give some information to be taken into account, however, no system
failure has occured, so there is no need for urgent precautions to take.
System messages Such a message is rather for a service engineer than a system operator, so it is displayed in the Alarm
Monitor Window only (it is not displayed in the Alarm Window).
Messages may be “new” — not acknowledged, and “actual” (alarm condition is presented) or “not actual”. Some
events cannot be actual (like information messages — for example, “Gyro filter started”).

4.2 Audible and Voice alarms
All generated alarms except the system messages are attended both by voice messages and beep noise.
Depending on a category of the appeared message the beep can sound before or after a voice message.
When appearing the information and/or warning messages the beep preceeds a voice message.
When generating the error and/or critical messages the beep sounds both before and after a voice message.
It should be noted that the beep sounds after a voice message until the alarm is acknowledged.
4.3 Alarm/Message Line
The last unacknowledged message is displayed on the Alarm/Message Line at the top of the screen (see Figure 4.1).
Figure 4.1: Alarm/Message Line
