Technical Information
Switching from one parameter to the next (using the "NEXT" key) indicates
confirmation of any changes made to the specific parameter. If the changes cannot
be accepted by the controller, the "Data out of limits" error message is displayed,
the changes are cancelled and the value of the parameter prior to the modification
is reproposed.
Switching from a parameter to the previous parameter (using the "PREVIOUS" key)
indicates the intention to abort any changes made to the specific parameter. Abort
is indicated by the caption "Changes aborted" that is displayed for approx. 1 second
before moving to the previous parameter.
The configuration environment has a tree-like structure and permits "circular"
navigation; on reaching the end of a branch, the user is returned automatically to
the start of this. Navigation can proceed in a forwards (NEXT button) or backwards
(PREVIOUS button) direction
It is possible to enter a sub-branch by pressing the "INCREASE" button. If no
buttons are pressed for more than 1 minute, the controller automatically quits the
programming environment canceling any modifications made to the current
parameter.
The figure below shows the first level of the configuration menu and the links to the
respective second level menus (indicated below).
