[-100.00 - 100.00 %]
Enter up to eight different preset references (0-7) in this parameter, using array programming. The preset ref-
erence is stated as a percentage of the value Ref
MAX
(par. 3-03
Maximum Reference
) or as a percentage of the
other external references. If a Ref
MIN
different from 0 (Par. 3-02
Minimum Reference
) is programmed, the preset
reference is calculated as a percentage of the full reference range, i.e. on the basis of the difference between
