PRODUCT OVERVIEW
Display item Description
4 Identification
number
Displays the identification number of the gyro currently selected. The stabilizer
identification number can be set in a password protected page of the Settings
menu.
In general, data presented on the various pages of the display refer to the gyro
whose ID is selected (and displayed) on this page.
5 Roll angle This information is derived from the IMU (Inertial Measurement Unit) inside the
control box and is presented in both digital and analogue form; digital data is in a
“two sign” format. See “Indication of roll and pitch angles on page 16.
6 Precession angle
(gyro sphere
angular position)
Precession angle given in both digital and analogue.
In digital form, it is presented as the actual angle (in degrees) of the gyro sphere
with respect to the vertical.
In analogue form, it is represented by a blue bar that originates from the center
and goes to the left or the right depending on the angle of the sphere. See “Indi-
cation of precession angle” on page 17.
7 Speed indication Flywheel rotation speed given in both digital and analogue.
In digital form, it is shown as a percentage of top speed (“day” speed); when the
system is accelerating, this indication goes from 0 % to 100 % (if the system is in
“day” mode) or to 65 % (if in “night” mode).
In analogue form, it is shown as a circular dial, whose red pointer indicates the
actual speed, expressed as percentage of top speed.
8 Bearing
temperatures
The temperatures of both upper and lower bearing packs are presented in the
form of two curved segments whose length increases proportionally to the meas-
ured temperature.
9 Pressure of
hydraulic circuits
The two pressure values are presented here in the form of two curved segments
whose length is proportional to the pressure itself.
10 Local time
(hours, minutes,
seconds)
Hour information is stored in the battery-powered real-time clock inside the gyro’s
Control Unit. The local time can be set reaching the “Set time” option described on
page 18.
11 Gyro working state Indicates the current operating state (“mode”) of the stabilizer.
See table on page 25.
