(30) Warning regarding countermeasures when external heading sensor related communication
abnormality is generated (See page 3-24.)
CAUTION
●
When an alert related to the external heading sensor (alert code "E", "F", "L" and "n") is
generated, the heading information (repeater signal and serial signal) immediately
before the alert was generated is outputted to the outside.
Once turn the steering mode to "MANUAL" or "Non Follow Up", and then determine the
true heading.
After the true heading is determined, the heading of this system is outputted to the
outside.
(31) Warning regarding countermeasures when external heading sensor related communication
abnormality is generated (See page 3-24.)
CAUTION
●
Determination of the true heading may cause large change of the outputted heading
information. During the automatic navigation, great care should be taken because
large course change may be happened.
(32) Warning regarding countermeasures when LOG (serial signal) communication abnormality
is generated (See page 3-25.)
CAUTION
●
When an alert related to LOG (serial signal) (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 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 (4) Countermeasures when LOG (serial signal) communication
abnormality is generated" in Chapter 3 Operating Method, for determination method of
the true heading.
(33) Warning regarding Countermeasures when LOG (serial signal) communication abnormality
is generated (See page 3-25.)
CAUTION
●
Determination of the true heading may cause large change of the outputted heading
information. During the automatic navigation, great care should be taken because
large course change may be happened.
