5.18 Selection of parameter settings
After finishing the mechanical adjustments, the control unit itself
must be "programmed" for adaption to the vessel's characteristics.
With the INFO button it is possible to call up a number of functions
and adjust parameters. Some of which are used under normal
operation, the others are set during installations and sea-trials.
The INFO function is divided into two levels. The first level is
accessed simply by pressing the INFO button, and contains functions
and settings used during normal operation.
The second level is accessed by keeping the INFO button pressed
while pressing and releasing the WEATHER button. This INFO level
contains functions and settings set during installation and sea trials.
Both levels are a closed loop and rotates one at a time each time the
INFO button is pressed. The parameter that is called up is shown in
the information display. The value of each parameter can be changed
by pressing the INCREASE or DECREASE button.
Note that some changes will occur when "THRUSTER" function is
selected (connecting J4-11 to J4-13).
In the table on page 5-48 the range of each function is listed, together
with a recommended value for setting before sea trial. Note the final
value selected under the sea trial, and also note any changes of
values.
Note !
Also use “SAVE PARAMETER” function to store all parameters after sea
trial. Refer to Debug loops page 5-44.
