……System Function Alarm ARPA (DATA) …………………………
When an abnormal state of an input signal or a trouble in the processing circuitry occurs, an character or
alarm is generated. When an alarm occurs against any ARPA function, ARPA (DATA) will appear in
the WARNING display area, but no indication is made in the ARPA information display. This status
means that there is any operational trouble in the ARPA system. Please, contact the service depot or the
manufacturer.
……Gyro Set Alarm SET GYRO ………………………………………
The North Stabilizing Kit (NSK) 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 SET GYRO alarm will be generated.
If this alarm occurs, set the gyro.
