System Function Alarm [ARPA (DATA)]･･････････････････････
When an abnormal state of an input signal or a problem in the processing circuitry occurs, a
character string or alarm is generated. When an alarm occurs for any ARPA function,
ARPA (DATA) will appear in the WARNING display area, but no indication is made in the
ARPA information display. The cause of the alarm may be an operational error in ARPA,
so please contact the service depot or 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 track gyro motions. However, the system stops
tracking the gyro if the power of the master gyro is turned off or if there are any problems
with the line. When the power of the master gyro is turned back on, the SET GYRO alarm
will be generated.
If this alarm is sounded, set the gyro.
