ALARM MESSAGES AND CORRECTIVE ACTIONS
13.1
The alarm system
Note!
Caution
988-12718-003
This section provides a description of system errors and corrective actions
that should be performed by the system operator.
The GC80/85 compass 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.
The audible and visual alarm may be disabled by DIP switch S1-8 on the
ICNT board (refer page 103). A failure will then only be indicated with
flashing display.
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.
For a complete list of alarm codes and explanation of the alert priority
system, refer page 116 onwards.
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
then be displayed by pressing the "ARROW UP" button.
The example above shows that alarm codes 2, 3, U, d and 7 were 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.
