NAVIKNOT 600 SD 056353/J
Alert Management Preliminaries 3-1
Chapter 3: Alerts
3.1 Alert Management Preliminaries
CAUTION
Risk of non-compliant System State / defective Alert Handling
Software update of the NAVIKNOT EU at least to version 3.000 and of all
installed CDUs at least to version
2.000 is mandatory for correct opera-
tion and alert handling of the NAVIKNOT system.
Operating the NAVIKNOT system with legacy software versions of the
NAVIKNOT EU and the CDUs (software mismatch) negatively impairs the
alert handling and causes non-compliance of the system.
Always make sure that the NAVIKNOT EU and CDUs are correctly
updated before operating the NAVIKNOT system.
Note In case of Software Mismatch, the NAVIKNOT system is in non-compliant
system state and the alert handling is not operable.
NAVIKNOT EU and CDU must correctly be updated before operating the
NAVIKNOT system again.
Proceeding with operating the NAVIKNOT system in a non-compliant
system state is not allowed.
Note NAVIKNOT complies with the statutory requirements regarding a serial
interface for the alert management (alert presentation and acknowledge-
ment) by a Central Alert Management System (CAM) following IEC 61162
(NMEA 0183) and MSC.302(87) (BAMS).
Note The NAVIKNOT alert management via the CAM interface can be chosen
by selecting different NMEA messages within the Service Setup 600
RS422 Output and NMEA Input settings:
NMEA Messages ALR/ACK, or
NMEA Messages ALF-ALC-ARC/ACN (BAMS)
Note The selection of the NMEA messages for the NAVIKNOT alert manage-
ment may be chosen according to ship classification requirements and
hardware equipment during installation and must not be changed after-
wards when the ship is in operation.
Note The NAVIKNOT alert management with NMEA message selection
ALR/ACK
differentiates between alarms and warnings as alert priorities.
The alert priority of the topmost alert and the total number of active alerts
are indicated in the alert display area of the main display.
Additional alert information as alert ID (two digit) and alert status are only
displayed in the alert list.
Note If NMEA messages ALR/ACK are selected for alert management,
the NAVIKNOT alerts have no IEC standard categorization.
