III Introduction
This Gyro Compass provides increased Rate of Turn and a broad range of input/output signals.
• WARNING - Operations
• Improper operations caused by failure of this product, or malfunctions caused by operator's misunderstanding
may cause collision or grounding and may result in property damage and environmental pollution. Also, death
or serious injury may happen.
• Full attention must be paid in the use of this product by understanding its limitations in performance and
characteristics. Thoroughly familiarize yourself with the operation of this product.
• CAUTION - General use
• This system displays Gyro Compass heading and outputs the heading information externally. Although the
safety design such as the alarm function against failure, etc., is provided, at the present time there is no
perfect safety design. In addition, as this system has many important functions, it is hard to say that any
one can use this system without failure. Failures or malfunctions of this system may cause distress, and
full attention should be paid in using this product. The use of this equipment does not absolve the user's
responsibility and obligation in practicing proper navigational techniques.
• Observe the following CAUTIONS:
• Always perform daily check to maintain normal system condition.
• When anomalies are detected as a result of daily checks, investigate and repair at once to restore to normal
conditions and request advice from Alphatron service engineer.
• When the alarm system is activated during use, always check to confirm the cause and reinstate.
It has the following features:
1. Automatic speed error correction.
2. Digital signal processing conform International Standards IEC61162.
3. Long service life.
This system has been designed to build an I - System : One gyro compass system.
Depending on the output signal the following type is provided: Step type : System mainly uses the step signal (repeater
signal).
III.1 Display and Alarm
For navigational safety considerations, various indicators and indicator lamps required for the system's operation and
alarm functions, have been built into the operating panel.
III.2 Types of Alarm Function
Alarms can be related to:
• GPS (alarm code "c" or "d")
• LOG (serial) (alarm code "P" or "U")
• Log Contact (alarm code "u")
• EXTERNAL HEADING SENSOR (alarm code "E", "F", "L" and "N")
• System is switched
• CAUTION - Types of Alarm
• When an alarm regarding 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.
• When an alarm regarding LOG (serial) (alarm code "P" or "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.
