3.0 Power Failures
There are two sources of power to the Seakeeper 5 Gyro:
• 12 Volts DC powers the Gyro Control Box for all the control electronics.
• 110 - 230 Volts AC powers the Motor Drive Box to drive the motor inside the Gyro.
These are supplied on Cables 1 and 2 which are shown on Seakeeper drawing 90296, 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. Gyro 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
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.
