GC80/85 Dual Gyro systems have been designed for any size of vessels
which requires more than 1 Gyro system. The system includes 1 common
Control unit, from which each Gyro system may be operated individually or
as 1 Dual system.
A GC80/85 Dual Gyro system enhances the navigational capabilities and
reliability. It eliminates the inconvenience and limitations of magnetic
compasses, and provides a variety of electrical outputs to supply accurate
and consistent heading information to other navigational equipment.
GC80 standard and GC85 high speed Dual Gyro systems have different
Sensitive elements, but use the same GC80/85 Dual MK2 Control unit. The
systems are identified by divergent DIP switch settings in Master compass
and in the Control unit.
A GC80 or GC85 system is identified by the labelling on top of the Master
compass' case as shown in the figure below.
The labelling on the Control unit is identical for both Gyro systems.
The GC80/85 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
GC80/85 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 checks to maintain normal system operation. Refer
MAINTENANCE, page 29 onwards.
