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.
