NOTE
If you change the setting value of the parameter
Inverted phases
, consider the following:
The device can take the new setting value only if the binary input signal
>Invert Phases
is not active.
Input signal:
>Phs-rotation reversal
The
>Phs-rotation reversal
binary input is used to switch between the
ABC
phase sequence and the
ACB
phase sequence. The switchover direction depends on the setting of the
Phase sequence
parameter. In
doing so, the phase sequence of all 3-phase measuring points is changed. Changing of the phase-rotation
reversal via the binary input is only possible if no measurands (< 5 % of the rated variables) are present at all 3-
phase measuring points.
Input signal:
>Invert Phases
The binary input
>Invert Phases
is used to activate the setting of the parameter
Inverted phases
. In
doing so, the phase sequence of the selected measuring point is changed. Changing of the phase sequence
via the binary input is only possible if no measurand (< 5 % of the rated variables) is present at the respective
3-phase measuring point.
