Range:
Function:
0.000
Unit
*
[-100000.000 – par.
3-03]
Enter the Minimum Reference. The Minimum Reference is the
lowest value obtainable by summing all references.
3-03 Maximum Reference
Option:
Function:
[0.000
Unit]
*
Par. 3-02 -
100000.000
Enter the Maximum Reference. The Maximum Reference is the

3-04 Reference Function
Option:
Function:
[0]
*
Sum
Sums both external and preset reference sources.
[1]
External/Preset
Use either the preset or the external reference source.
Shift between external and preset via a command on a digital input.
2.5.2. 3-1* References
Parameters for setting up the reference sources.
Select the preset reference(s).
Select Preset ref. bit 0 / 1 / 2

3-10 Preset Reference
Array [8]
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.
