Technical Information
Programming
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).
