Section 3: POWER FAILURES, ALARMS, AND TROUBLESHOOTING
3.0 Power Failures
There are two sources of power to the Seakeeper 6:
12 Volts DC powers the Seakeeper Control Box for all the control electronics.
110 - 230 Volts AC powers the Motor Drive Box to drive the motor inside the Seakeeper.
These are supplied on Cables 1 and 2 which are shown on Seakeeper drawing 90396, Cable
Block Diagram.
The Motor Drive Box contains hazardous voltage
and the cover should not be removed while the
flywheel is spinning and the AC input has been
disconnected for at least 10 minutes. This high
voltage exists even if the flywheel is coasting
down and the supply voltage has been shut off.
3.1 +12 VDC Failure
The display will be blank. Seakeeper flywheel speed will decrease. The brake is locked (no
precession).
Verify the boat’s circuit breaker supplying +12 VDC has not tripped and the AC breaker
is On.
When +12 VDC is restored, the display will be powered up, Splash Screen will appear,
and then Home Screen will appear.
Press Power On/Off button
The progress bar will appear and indicate flywheel speed. When the flywheel is at
minimum operating speed, the stabilize button will appear so stabilization can be turned
on. This may take up to 30 minutes, depending on the speed of the flywheel when the
+12 VDC low current is turned back on.
