4.6.5.9 System Internal Communication Failure (1) (alarm code E) or System Internal Communication
Failure (2) (alarm code F)
1. Confirm that the external heading sensor signal processing unit of this system operates properly.
2. Contact Alphatron Service Engineer, or agent, after checking step 1.
4.6.5.10 Master Compass Heading Failure (alarm code G)
•
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.
1. Confirm that the Gyro Compass True Heading displayed in this system coincides with the heading by some target, or
by observation.
2. Make correction according to Confirmation of True Heading on page 44, if there is an error is detected in step 2.
3. Contact Alphatron Marine Service Engineer, or agent, after checking steps 1 and 2.
4.6.5.11 External Heading Sensor Communication Stop (alarm code L) or External Heading Sensor
Data Failure (alarm code n)
1. Confirm that the external heading sensor operates properly.
2. Operate it according to the Operator's Manual for the external heading sensor, if it does not operate properly.
3. Take appropriate actions according to Corrective Measures External Heading Sensor Communication Failure on
page 51, if it was not recovered after executing step 2.
4. Contact Alphatron Marine Service Engineer, or agent, after checking steps 1 to 3.
4.6.5.12 LOG (serial signal) Communication Stop (alarm code P) or LOG (serial signal) Data Failure
(alarm code U)
1. Confirm that LOG operates properly.
2. Operate it according to the Operator's Manual of LOG, if it does not operate properly.
3. Change the input system according to Corrective Measures LOG (serial signal) Communication Failure on page 51,
if it was not recovered after executing step 2.
4. Contact Alphatron Marine Service Engineer, or agent, after checking steps 1 to 3.
4.6.5.13 LOG Contact Failure (alarm code u)
1. Confirm that LOG operates properly.
2. Operate it according to the Operator's Manual of LOG, if it does not operate properly.
3. Change the input system according to Corrective Measures LOG (contact) Failure on page 52, if it was not
recovered after executing step 2.
4. Contact Alphatron Marine Service Engineer, or agent, after checking steps 1 to 3.
