Kongsberg cJoy OT
Normally, input from the wind sensor will be enabled. The system then receives and
compares the signal from the sensor and uses it to calculate the wind force acting on
the vessel.
The raw measurements of wind speed and direction are filtered internally (using a
Kalman filter with both low and high frequency parts), to estimate the most reasonable
speed and direction values to be used by the system.
Displayed wind information
An indication of the measurements from the wind sensor is shown in the
Wind
area of
the Main view (see Main view on page 28). You can examine the status and measured
values for the wind sensor on the Sensor view (see Sensor view on page 38).
Enabling the wind sensor
To enable the wind sensor, proceed as follows:
1 Display the Sensor Enable input dialog.
2 Check that the colour of the
Ready
field for the wind sensor is green.
3
Move the focus to the
Enable
field for the wind sensor and change the option to
On
.
4 Press the
Enter
button.
• The wind sensor is enabled.
5 Close the Sensor Enable input dialog.
Disabling the wind sensor
To disable the wind sensor, proceed as follows:
1 Display the Sensor Enable input dialog.
2 Move the focus to the
Enable
field for the wind sensor and change the option to
Off
.
3
Press the
Enter
button.
• The wind sensor is disabled.
4 Close the Sensor Enable input dialog.
Faulty wind sensor
If the measurements from the wind sensor are not accepted by the system, a message
is given with information about the failure, for example:
Wind 1 not ready
When the wind sensor has been repaired and is ready for use, you should enable it again.
Rejection of faulty wind data
A fault causing jumps in readings from the wind sensor could lead to an unwanted
change in thrust force.
