Gyro Set Alarm - JRC JMA-9133-SA Instruction Manual

JMA-9100 Instruction Manual
When it is impossible to continue tracking any acquired and tracked target, or the
data of AIS target cannot received for a specified time, the
will be generated. The typical causes for alarm generation are shown below, but
not limited to the following:
• The target echo is very weak.
• The target is shadowed by a shore or a large ship and its echo is not received.
• The target echo is blurred by sea clutter returns.
If a target under tracking goes out of a range of 32 nm and can no longer be
tracked, it is canceled without a lost target alarm.

Gyro Set Alarm

The GYRO I/F in this system receives signals from a gyro. Even if the power is
turned off, the system will follow up the gyro. However, the system stops the
follow-up operation when the power of the master gyro is turned off or when any
trouble occurs to the line. When the power of the master gyro is recovered, the
alarm will be generated.
