TG-8100/8600-D: Two gyrocompasses system (Standard Dual gyrocompasses)
For the above systems, -S and -D, the following types are provided depending on the
output signal.
Step type : System mainly the step signal (repeater signal) used
Serial type : System mainly the serial signal (repeater signal) used
1.2 Display and alert
Considering the navigational safety, various indicators and indicator lamps required for
the system operation and alert function are built in the system.
These are concentrated and arranged on the operating panel.
1.3 Kinds of function
CAUTION
●
When an alert related to GNSS (alert code "c" or "d") is generated and the gyrocompass
true heading has not been determined, once turn the steering mode to "MANUAL" or
"Non Follow Up", then determine the true heading because erroneous heading
information (repeater signal and serial signal) is possible to be outputted to the outside.
Refer to "3.4.5 (2) Countermeasures when GNSS communication abnormality is
generated" in Chapter 3 Operation, for determination method of the true heading.
●
When an alert regarding to LOG (serial) (alert code "P" or "U") is generated and the true
heading of the gyrocompass has not been determined, once turn the steering mode to
"MANUAL" or "Non Follow Up", then determined the true heading because the
erroneous heading information (repeater signal and serial signal) is possible to be
outputted to the outside. Refer to "3.4.5 (4) Countermeasures when LOG (serial)
communication abnormality is generated" in Chapter 3 Operating Method, for
determination method of the true heading.
●
When an alert regarding to the log contact (alert code "u") is generated and the true
heading of the gyrocompass has not been determined, once turn the steering mode to
"MANUAL" or "Non Follow Up", then determine the true heading because erroneous
heading information (repeater signal and serial signal) is possible to be outputted to the
outside. Refer to "3.4.5 (5) Countermeasures when LOG contact abnormality is
generated" in Chapter 3 Operating Method, for determination method of the true
heading.
●
When an alert regarding to the external heading sensor (alert code "E", "F", "L" and "N")
is generated, the heading information immediately before the alert generated is
outputted. Once turn the steering mode to "MANUAL" or "Non Follow Up", and then
determine the true heading. Refer to "3.4.5 (3) Countermeasures when external
heading sensor related communication abnormality is generated" in Chapter 3
Operating Method, for determination method of the true heading.
After the true heading is determined, this system's heading is outputted to the outside.
●
When the system is switched, perform it after once turned the automatic steering
system to "MANUAL" or "Non Follow Up" to prevent course turning with larger angle.
