Argus Radar Operator Manual
Alert and system failures
In the alert section (“System data area sections” on page 23) the system will visualise all
information regarding alerts. The system will continuously check for danger situations and
system faults while running.
External bridge alert systems
The system supports Bridge Alert Management (BAM) and Bridge Navigational Watch Alarm
Systems (BNWAS).
Bridge Alert Management (BAM)
All system alerts are transferred to the bridge alert system if this is connected to the system.
An alert generated by the system - e.g. Danger target alarm - can only be acknowledged from
the system itself. Global alarms - e.g. Position timeout or Gyro failure - can be acknowledged
on both the system control unit and on the bridge alert system.
Bridge Navigational Watch Alarm Systems (BNWAS)
If a BNWAS is connected to the system, the system can output an EVE sentence to the BNWAS
when an user interaction with the system occurs.
Type of alerts
There are 3 alert types in the system:
•
Alarms:
This is the system’s highest priority alert, activated when situation occurs that might
result in collision, or for conditions that critically e
ffect the capability or performance of the
system. An alarm is accompanied by an audible signal (3 short signals repeated every 7 sec-
onds), and the alarm icon i
s flashing until the alarm is acknowledged.
•
Warnings:
This is alerts of lower priority, announcing conditions that could result in un-
wanted system response or eventual failure if no action is taken. A warning is accompanied
by an audible signal (2 short signals repeated every 60 seconds, until acknowledged), and the
warning icon is flashing until the warning is acknowledged.
•
Cautions:
This is information about danger and caution objects that requires attention. Cau-
tion alerts have no audible signal.
Aler
t notifications
When an alert is triggered, the alert appears in the Alerts panel. The latest and most severe
alerts are displayed in the Alerts panel. To access the entire list, move the cursor to hover over
the Alerts panel, and then press the left trackball button.
The alerts are displayed in a sorted order. The sort order is the severity (i.e. alarm before warn-
ing), then age.
Alarms and Warnings have different states:
•
Active - not acknowledged, not silenced
•
Active - not acknowledged, silenced
•
Active - acknowledged
•
Active - responsibility transferred to another work station
•
Rectified - not acknowledged
When a rectified alert is acknowledged it will disappear from the Alerts panel.
Cautions are not acknowledged, and they disappear from the system when they are rectified.
Cautions have therefore only an active state.
The table below shows alert icon and behavior depending on if the alert is active, acknowl-
edged, transferred or rectified.
