Section 3: POWER FAILURES, ALARMS, AND TROUBLESHOOTING
3.2 230 VAC Failure
If an AC failure longer than thirty seconds occurs, the motor will be disabled and the flywheel speed will
start to decrease. The brake is locked and the gyro will stop moving. A “Drive Fault” alarm will occur.

Verify the boat’s circuit breaker supplying 230 VAC to the Motor Drive Box has not tripped.

Verify that the circuit breaker on the Motor Drive Box has not tripped.
Once 230 VAC is restored:

Press POWER ON/OFF
The progress bar will appear and indicate Gyro flywheel speed. When Gyro flywheel is at
minimum operating speed the progress bar will turn green and stabilization can resume.

Press LOCK/UNLOCK
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 (208 – 230 VAC) or if the
AC voltage fails for less than thirty seconds, the Motor Drive Box will briefly shut down for protection,
but will reset itself and continue operating. In this case a “Drive Fault” alarm will not occur. The
operator will not be aware of the power disturbance unless there are 4 power disturbances in 1 hour. In
this case, a FREQUENT DRIVE RESET warning will be issued. If this warning occurs, Seakeeper
recommends that the cause of this large voltage variation be investigated as it could damage electronic
components on the boat.
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 Model 8000 Gyro issues an alarm when it detects a malfunction that could cause damage or erratic
operation. When an alarm occurs the Gyro switches to Stop and Lock, and an alarm message is shown
on the Display. If installed, the audible alarm will sound until the operator presses the POWER ON/OFF
key on the Display.
