I.3 Glossary
The meaning of standard definitions and terms as used in this manual are explained in the table of Definitions Table 1:
Table of Definitions on page 6.
Definition Explanation
External Heading Sensor General term for the Heading Detection Sensor for Magnetic Compass System,
Electronic Compass, GPS Compass, etc.
External Heading Sensor
Signal Processing Unit Optional unit to this system. It enables to completely backup several circuits of the
repeater signal (step signal / serial signal) by attachment of this unit when connected to
the external sensor.
Fixed Error Error between this system and keel line depending on the installation.
Last Azimuth This system can set and detect last azimuth of previous stop time. According to this
operation, system settling time can be reduced when started the system again.
Leveling operation Operation to keep the sensor horizontal
Magnetic Compass System The heading detector is mounted on the magnetic compass and detected heading signal
from the heading detector is sent out as repeater signal and serial signal.
Rate of Turn Speed of ship's turning
Sensitive Element Element to detect north of own ship
Speed Error Correction Gyro-compass generates error from the North depending on the speed and position
of ship's navigation. This system automatically calculates and corrects this error using
speed and position data.
Step Signal Three phase signal with resolution of 1/6°. Voltage is 24 V standard. 70 V / 35 V output
can be put out by expanding with the optional unit.

I.4 Storage
Observe the following items when storing:
1. Turn all power switches of this system to the OFF position to disconnect the power.
2. Storage temperature should be between –
20℃
to
+55℃.
3. Avoid a place with high humidity as much as possible.
4. Prevent the storage place from generating corrosive gas, breeding of bacteria such as mold or intrusion of insects
and small animals.
5. Cover the system with a plastic sheet, etc., when generation of dust is foreseen. When welding works, etc., are
carried out near this system, provide suitable protection to prevent damage caused by sparks, etc.
