Parameter:
Minimum value
•
Default setting
Minimum value
=
1
Parameter:
Maximum value
•
Default setting
Maximum value
=
15
The parameters
Minimum value
and
Maximum value
are initially calculated by DIGSI 5 based on the tap
coding, the
Number of tap positions
, and the
Tap-display offset
. They represent the allowed
control area of the position value. Positions outside this area are defined as invalid. This control area can be
further restricted within the initially set physical range (see
Number of tap positions
and
Tap-
display offset
).
Parameter:
Tap-display offset
•
Default setting
Tap-display offset
=
0
If you want to move the height of the displayed value in a positive or the negative direction with respect to
the height of the actual value, enter the value for this in the
Tap-display offset
field.
Parameter:
Number of bits f. tap code
•
Default setting
Number of bits f. tap code
=
4
With the
Number of bits f. tap code
parameter, you set the number of bits you need for encoding the
transformer taps. The number is dependent on the selected Encoding and on the Moving contact. For
example, you need 3 bits for 7 binary-encoded transformer taps. The range of values extends from 2 to 32.
