7. Operating System
The exciter is controlled by a microprocessor system. Software operations may
be grouped into two broad categories: start-up and normal operation.
7.1 Using the encoder
The interaction between the user and the exciter’s control software is performed
using the encoder.
Figure 7.1
The possible operations that you can carry out on the encoder are:
•
rotation
: moves the cursor shown on the display; if you turn the encoder
to the left (counterclockwise), the cursor moves downwards, if you turn
it right the cursor moves upwards; it also permits to increase or diminish
the parameters (turning the encoder left diminishes the parameter,
turning it right increases it) or to select an item from a list of options.
The rotation of encoder causes the lighting of the display, in case it is not been
lighted.
•
pushing
: push the button once when the cursor is on the name of a
menu to enter in that menu, push it when the corsor is on the name of a
parameter to enter in modification mode (the cursor starts blinking); after
the modification of a parameter, push the button to save the new value.
The pushing of encoder causes the lighting of the display, in case it is not been
lighted.
After having modified the value of a parameter, the cursor goes on blinking for
approximately 10 seconds, waiting for confirmation from the user. If the user doesn’t
confirm the new value (i.e., the button is not pressed), the cursor stops blinking
and remains on the selected parameter.
Turn the encoder counterclockwise
to move the cursor downwards, to
decrease the value of a parame-
ter or to choose an element from
a list of possibilities
Turn the encoder clockwise to
move the cursor upwards, to in-
crease the value of a parameter
or to choose an element from a
list of possibilities
Push the button once to enter in the desired
menu, to enter in modification mode or to
confirm a choice
