NORMAL SHUTDOWN
•
Verify that no alarms are present on the Gyro
display
•
Depress Lock (Lock lamp will illuminate in a few
seconds)
•
Depress Run (Run lamp will go out and flywheel
will start to coast)
!
•
It is important to keep both AC and DC power “on” so the boat’s seawater pump
and the gyro’s glycol pump are running until the flywheel coasts down to 5000
rpm. Seakeeper appreciates that this places an unusual requirement on the boat
operator as it takes 1.5 hours for the flywheel to coast down to 5000 rpm. The
flywheel bearings are still generating significant heat during the first half of the
coast down cycle and Seakeeper requests that this procedure be followed until we
gain more experience and can issue an updated operational instruction to reduce
the “power on” time during coast down.
•
Turn “Off” the boat’s AC and DC circuit breakers that supply power to the Gyro.
