•
Change of the ship's Speed Input System and the Latitude Input System, or large change of the ship's speed
and latitude, may cause a large change of the Gyro Compass True Heading. When on automatic steering,
first turn the steering mode of the automatic steering system to "MANUAL" to prevent a large course change.
Confirm the area around the ship is clear and turn to "AUTO" steering again.
•
CAUTION - Confirmation of Latitude
•
Change of the latitude input system or large change of the latitude may cause a large change of True
Heading. When on automatic steering, first turn the steering mode of the automatic steering system to
"MANUAL" to prevent a large course change. Confirm the area around the ship is clear and turn to "AUTO"
steering again.
•
CAUTION - Confirmation of Ship Speed
•
Change of the ship's speed input system or large change of the ship's speed may cause a large change of
True Heading. When on automatic steering, first turn the steering mode of the automatic steering system to
"MANUAL" to prevent a large course change. Confirm the area around the ship is clear and turn to "AUTO"
steering again.
•
CAUTION - System Selection
•
System selection (switching) may cause large change of True Heading. When on automatic steering, first turn
the steering mode of the automatic steering system to "MANUAL" to prevent a large course change. Confirm
the area around the ship is clear and turn to "AUTO" steering again.
•
CAUTION - Operating Procedure Master Compass Switch (Option)
•
DO NOT touch the Master Compass Power Switch while the Gyro Compass operates normally, to prevent
serious damage to the sensitive element, reduce the life cycle of the product, or unexpected problems. The
Master Compass Power Switch must be operated only when the master compass is in abnormal condition.
•
CAUTION - Alarms
•
When the following alarms are activated, the heading information from this system may not be sent at all,
or may have a large error. All units operated by the heading information from this system (in particular, the
automatic steering system, etc.) should be operated immediately according to the individual emergency
operating procedure.
•
CAUTION - Corrective Measures GPS Communication Failure
•
When an alarm related to GPS (alarm code "c" or "d") is activated and the Gyro Compass' True Heading has
not been determined, first turn the steering mode to "MANUAL", or "Non Follow Up", then determine the True
Heading, because wrong heading information (repeater signal and serial signal) may be sent out.
•
CAUTION - Corrective Measures GPS Communication Failure
•
Determination of the True Heading may cause large change of sent heading information. During automatic
navigation, great care should be taken, because large course changes may have happened.
•
CAUTION - Corrective Measures EXTERNAL HEADING SENSOR Communication Failure
•
When an alarm regarding the EXTERNAL HEADING SENSOR (alarm code "E", "F", "L" and "N") is activated,
the heading information (repeater signal and serial signal) immediately before the alarm generated is sent.
First turn the steering mode to "MANUAL" or "Non Follow Up", and then determine the True Heading. Once
True Heading has been determined, the system's heading is sent out.
•
CAUTION - Corrective Measures EXTERNAL HEADING SENSOR Communication Failure
•
Determination of the True Heading may cause large change of sent heading information. During automatic
navigation, great care should be taken, because large course changes may have happened.
•
CAUTION - Corrective Measures LOG Communication Failure
•
When an alarm regarding LOG contact (alarm code "u") is activated and the Gyro Compass' True Heading
has not been determined, first turn the steering mode to "MANUAL" or "Non Follow Up", then determine the
True Heading because wrong heading information (repeater signal and serial signal) may be sent externally.
•
CAUTION - Corrective Measures LOG Communication Failure
•
Determination of the True Heading may cause large change of sent heading information. During automatic
navigation, great care should be taken, because large course changes may have happened.
•
CAUTION - Corrective Measures LOG Contact Communication Failure
