Chapter 7 Alerts
The alert management system generates
alerts related to displayed information or
equipment malfunction.
In addition, prompts (permanent and/or
temporary) are raised to communicate
information that does not necessarily require operator action.
The Alerts menu includes a Mute Settings facility, which enables the
operator to either change the length of time the alert buzzer is temporarily
muted, or mute the alert buzzer for an unlimited period of time.
Alerts
There are three types of alert priority:
•
Alarms
•
Warnings
•
Cautions
Alarms and warnings are indicated visually and audibly, via the alert
buzzer. Cautions are only indicated visually.
The following conditions apply to the three different types of alerts:
1. Alarms are conditions that require immediate attention or user
action.
2. Warnings indicate changed conditions requiring attention for
reasons of precaution which are not immediately hazardous but
may become so if no decision or action is taken.
3. Cautions indicate a condition which does not warrant an alarm or
warning, but still require attention and consideration of the
condition.
Alerts are initially displayed on the Alert Status Indicator, from where they
can be acknowledged. An unacknowledged alert displays as a flashing
colour whereas an acknowledged, but still existing alert, displays a
constant colour, see Alert Status Indicator.
Alerts are raised until they are acknowledged, and the visual indications of
individual alerts remain until the fault has been corrected, when the alert
system automatically resets to normal operating condition. Alerts can only
be cancelled if the condition causing them has been dealt with successfully.
For some alerts, the system may provide the acknowledgement
automatically and clear the alert.
