GYRO STABILIZER OPERATION
Note:
- It takes about 25 minutes for the flywheel to
reach 65 % of the top speed
- After the flywheel speed reaches 65 % of
the top speed, it will reach the set speed in
about 30 minutes in day mode and about
10 minutes in night mode.
Note:
- Precession is locked and stabilization is
turned off when the boat is turning at high
speed with a small turning radius. The IMU
(Inertial Measurement Unit) of the gyro sys-
tem automatically senses this condition and
activates precession lock; precession move-
ments and consequently stabilization is
automatically restored whenever this high
acceleration state is no longer present.
- During precession lock due to high acceler-
ation conditions, the circle around the pre-
cession icon turns red, as when precession is
intentionally stopped.
Temperature derating
If, during normal operation, an over tempera-
ture condition is found in the gyro (in the inter-
nal bearings or in the Inverter Box), the system
automatically reduces the power supplied to
the motor, in order to keep the temperature
within safe limits; flywheel speed is reduced as
well.
This condition is indicated by an orange ther-
mometer icon displayed on the bottom left of
the Home page (Figure 9).

This condition may happen, for example, if sea-
water hoses connected to the heat exchanger
are clogged.
Normal operating conditions are automatically
restored once the over temperature condition
has been removed.
