12 ALERT MESSAGES AND CORRECTIVE ACTIONS
This section provides a description of system errors and corrective actions
that should be performed by the system operator.
12.1 The alert system
The GC80/85 system will continually check for faults while the system is
running.
If any alarm is generated, verify the reason for the alarm.
If a fault occurs, an alert code will be displayed in the LCD. The alarm lamp
will be flashing and an audible alarm will be activated.
Up to 4 alarm codes may be displayed in the LCD to indicate that several
alarm situations are present. The last activated alarm will be displayed on
the right side of the display. The figure below shows that alarm codes 1, 3
and 2 were generated in that order.
Caution
When an alarm is generated, bearing information from the GC80/85
may not be present or may have large error. Any equipment using
bearing information from the Gyro compass should therefore
immediately be operated according to the equipment’s emergency
operating procedure.
Alert display
Select <ALERT> in the display menu list to access the display.
In the alerts display, you can review the alert history and further details
(date and cause).
