Section 3: POWER FAILURES, ALARMS, AND TROUBLESHOOTING
3.2
230 VAC Failure
If the AC power is not connected, a notification screen will indicate “AC Mains Low”. If the failure is not
corrected within two minutes, an “AC Mains Low” alarm will occur. The brake will lock and the gyro will
stop moving if stabilization was on.
•
Verify the boat’s circuit breaker supplying 110-230 VAC to the Motor Drive Box has not tripped.
Once 110-230 VAC is restored:
•
Press POWER ON/OFF
to clear the alarm. Then press the POWER ON/OFF button again to
continue gyro operation.
The progress bar will appear and indicate Gyro flywheel speed. When Gyro flywheel is at
minimum operating speed the progress bar will go away and stabilization will begin.
3.3
230 VAC Fluctuation, Spike or Momentary Failure
If the AC voltage to the Motor Drive Box is outside Seakeeper’s specified range (110 – 230 VAC), the
Motor Drive Box will briefly shut down for protection. The Motor Drive Box will continue operation
when the voltage returns to the specified range.
A brief fluctuation can happen when the generator is unable to regulate its output voltage, particularly
when a large AC load is switched on or off. A momentary AC failure also happens during transition from
shore power to ship’s power.
3.4
Alarms
The Gyro issues an alarm when it detects a malfunction that could cause damage or erratic operation.
When an alarm occurs, the Gyro will stop and an alarm message is shown on the Display.
The alarm will not clear until the operator presses the POWER ON/OFF button and the alarm condition is
no longer present. The operator can then press the POWER ON/OFF button again to continue gyro
operation.
