SYSTEM OVERVIEW
20221537 / D 3
1.2 Precaution in use
The GC80/GC85 Dual Gyro system displays and outputs
bearing information. Although the system continually checks for
faults while the system is running, failures or malfunctions may
occur.
Any errors in input information will generate an alarm. These
errors may also cause large jumps in the output bearing from the
gyro compass. If this happens, any external equipment
depending on the bearing output from GC80/GC85 should be
operated manually or switched to other bearing sensors.
To assure long time safe operation, the following precautions
should be taken:
- Assure that the operator is familiar with the use of the
gyro compass
- Perform daily check to maintain normal system operation.
Refer MAINTENANCE, page 29 onwards
- If any unusual behavior is observed during daily
inspection, the cause should be found and corrected. If
necessary, the local Simrad dealer should be contacted
- If any alarm is generated, verify the reason for the alarm
