When the alert related to the external heading sensor is generated, the true heading
of the data indicator
⑧
is blinking.
The true heading which is currently indicated is the heading immediately before the
alert was generated if the alert has been continued, and the heading currently
received if the alert has been recovered.
When the alert is continued, the true heading cannot be determined.
The true heading outputted to the external is the heading immediately before the
alert was generated.
1. Confirm that the alert related to the external heading sensor has been recovered.
2. Push ACK / ENT switch
④
in the state where the true heading is indicated.
3. The external heading sensor true heading indication for the true heading goes lit,
and the outputted true heading to the external is also determined true heading.
(4) Countermeasures when LOG (serial signal) communication abnormality is
generated
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 "3.4.4 (4) Countermeasures when LOG (serial signal) communication
abnormality is generated" in Chapter 3 Operating Method, for determination method of
the true heading.
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.
When abnormality related to LOG (serial signal) is generated, the data indicator
⑧
is
blinking.
The gyrocompass true heading and the heading information outputted to the external
which are currently indicated, is the corrected value based on the ship's speed
immediately before the alert was generated.
1. Select the other than "LOG (serial signal)" for the ship's speed input system.
(Refer to "3.4.1 (7) Setting of the ship's speed input system.)
2. As the gyrocompass true heading calculated from the corrected ship's speed is
blinking, determine the true heading by pushing ACK / ENT switch
④
.
3. The true heading indication goes lit and the true heading outputted to the external
is also determined.
