Both of the Dual systems at each separate Gyro will continually check for
faults while the system is running.
If a fault occurs, an alarm code will be displayed in the LCD, the Alarm lamp
will be flashing, and an audible alarm will be activated.
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.
Alarm messages on the compass control panels
Up to 4 alarm codes may be displayed in the LCD at the same time to
indicate that several alarm situations are present. The last activated alarm
will be displayed on the right side of the display. The figure shows that
alarm codes 1, 3 and 2 were generated in that order.
If more than 4 alarms are active, this will be indicated with a dot behind
the last number as shown in the figure below. Further alarm codes may be
displayed by pressing the "ARROW UP" button.
The example shows that alarm codes 2, 3, U, d and 7 were activated.
When an alarm is generated, bearing information from the GC80/85 may
