GYRO STABILIZER OPERATION
SG60 Operation Manual
3. Make sure the flywheel is completely
stopped, turn off the seawater pump (if
connected to a circuit other than the gyro
system), and turn off the DC and AC power
protection breakers.
Note:
- If the seawater pump is driven by the gy-
roscope, it remains powered as long as the
flywheel speed is above 300RPM. When the
speed drops below this value, the pump is
de-energized. However, even below this
speed, if the bearings temperature is above
45°C, the pump will remain in operation.
- The glycol pump, on the other hand, re-
mains energized even when the flywheel is
stopped and as long as the temperature of
bearings is above 45°C.

Note:
- The circle around the power (ON/OFF) icon
goes grey and the circle around the preces-
sion lock toggle icon goes red: precession is
locked and the flywheel begins to deceler-
ate.
- When you press the icon and turn off the
gyro, power is removed from the motor
and the flywheel begins to decelerate; the
flywheel speed is still shown on the display
up to about 500 rpm but not below that.
Wait at least 15 minutes after the flywheel
speed indication disappears before ap-
proaching the gyro.
- If the flywheel was spinning at full speed, it
will take about 2 hours to come to a com-
plete stop.
