Technical Alarm Messages
This section lists major technical alarms, their default priority, indication on alarm reset, and the actions that can
be taken when an alarm occurs. Some of alarms may not be included.
Technical alarms give different alarm indicators when the alarm system is reset. In this section we classify the
technical alarms into three categories for easy clarification:
■
A: technical alarms are cleared. The monitor gives no alarm indications.
■
B: technical alarms are changed to the prompt messages.
■
C: the alarm is silenced and a √ appears before the alarm message, indicating that the alarm is
acknowledged.
In the following tables we will use A, B, and C to refer to the indications on alarm reset.
