0.00%
*
[-100.00 - 100.00 %] Enter up to eight different preset references (0-7) in this pa-
rameter, using array programming. The preset reference 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 Ref
MAX
and Ref
MIN
. Afterwards, the value is added to
Ref
MIN
. When using preset references, select Preset ref. bit 0 /
1 / 2 [16], [17] or [18] for the corresponding digital inputs in
parameter group 5.1* Digital Inputs.
