System messages
The ECDIS message system
The system will continuously check for danger situations and system faults while the system
is running.
In the system, the alert escalation is set to 60 seconds and users are not able to change the
alert escalation time.
There are 3 types of messages displayed in the Alerts panel:
• Alarms: This is the system's highest priority alert, activated when situation occurs that
might result in collision with other vessels, when you enter shallow water area, or for
conditions that critically effect the capability or performance of the system. You must
critically examine all alarm messages to determine their cause and effect.
Alarms are followed by an acoustic alarms. The alarm icon is flashing until the alarm is
acknowledged.
• Warnings: This is alerts of lower priority, announcing conditions that could result in
unwanted system response or eventual failure if no action is taken
-
Warnings are sounded with two beeps every minute while active.
- All warnings are repeated as warnings except the following which are repeated as
alarms:
• Early course change (timeout = 30 sec.)
• Actual course change (timeout = 30 sec.)
• Outside the anchor watch swing circle (timeout = 2 min.) which are repeated as
alarms.
• Navigational cautions: Information about danger and caution objects within the guard
zone defined for your vessel. See "Setting a guard zone around the vessel" on page 31.
Alert notifications
When an alert is triggered, the alert icon appears in the alert panel. The alerts are also added
to the Alerts list, displayed from the main menu.
Alarms trigger an audible signal unless the sound is turned off in the System Settings dialog.
Alarms and Warnings have different states:
• Active - not acknowledged
• Active - acknowledged
• Rectified - not acknowledged
When a rectified alert is acknowledged it will disappear from the alerts panel and from the
Alerts list.
Cautions are not acknowledged, and they disappear from the system when they are no
longer present. Cautions have therefore only an active state.
The table below shows alert icon and behavior depending on if the alert is active,
acknowledged or rectified.
