•
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 out.
•
CAUTION - Troubleshooting
•
When an alarm is activated, immediately confirm content of the activated alarm and take appropriate
measures.
●When
a failure has been activated, confirm area around the ship is clear to perform check and
take appropriate measures in non-hazardous sea area, stopping the ship as a rule.
•
CAUTION - Corrective Measures
•
Before checking and replacing of fuses, and disconnecting / connecting of each unit, connector, printed
circuit, terminal cable, turn "OFF" the power switch of the operating panel, and disconnect the power cable
from the ship’s distribution board, etc. It may cause electric shock and failure if left in "ON" position.
•
CAUTION - Failure Phenomena Corrective Measures
•
Whenever the internal setting of the system is changed, follow instructions of the Alphatron Service Engineer.
•
When another failure is activated than appeared in this clause, or a replaced fuse has blown again, turn
"OFF" the power switch of the operating panel, disconnect the power cable from the ship’s distribution board
and request repair from an Alphatron Service Engineer.
•
When a failure has occurred and it has not been repaired according to this clause, turn "OFF" the power
switch of the operating panel and request an Alphatron Service Engineer to repair it on making a call to port.
Even if it has been repaired, request an Alphatron Service Engineer to check it.
•
CAUTION - Rotor Level Failure (alarm code 6)
•
Turn OFF the power switch.
•
CAUTION - Zero Cross Failure (alarm code 8)
•
Determination of the Gyro Compass True Heading when alarm code 8 is activated, may cause a large
change of the True Heading. During automatic navigation, take great care, because a large course change
may have happened.
•
CAUTION - Master Compass Heading Failure (alarm code G)
•
When an alarm code G is activated, the Gyro Compass True Heading may have an error. New input of the
True Heading may cause a large change of the True Heading. When on automatic navigation, first turn the
steering mode to "MANUAL", then determine the True Heading to prevent turning course with larger angle.
Confirm area around ship is clear and turn to "AUTO" steering again.
•
CAUTION - The Gyro Compass does not operate, when turned ON and the power switch on the operating
panel is turned ON.
•
Be aware of electric shock when checking the main power supply.
•
When checking fuses, turn OFF the power switch on the operating panel and disconnect the power cable
from the ship’s distribution board before checking fuses.
•
CAUTION - Not all repeaters operate
•
When checking fuses, turn OFF the power switch, and disconnect the power cable from the ship’s distribution
terminal board.
•
CAUTION - No repeaters operate
•
When checking fuses, turn OFF the power switch, and disconnect the power cable from the ship’s distribution
board.
•
CAUTION - Maintenance and check
•
Main units of this system consist of electronic circuits of high reliability. If a failure occurs, perform the check
and maintenance as described in this chapter and correct the fault(s) to prevent further risk of failure and to
maintain the system's performance. Failure to carry this out, the detection of the failure sign will be delayed
and may cause accidents such as collision or grounding.
