Various groups of parameters are grouped together in blocks to aid in the rapid na-
vigation through the large number of configuration screens. Selecting "YES" or
"NO" does not determine if control or monitoring is performed. The user’s selec-
tion has the following effect:
YES
.............. The configuration screens in this block are displayed and can either
be viewed ("Select" push button) or modifications can be made to the
parameters ("Cursor
→
", "Digit
↑
" or "Select" push buttons). This
does not disable or enable individual parameters, only if the individ-
ual parameters in this parameter block may be accessed for modifica-
tions.
NO
................ The parameters in this block are not displayed, cannot be modified
and are therefore skipped.
