20.15.5 Operation principle
Every Signal matrix for analog inputs function (SMAI) can receive four analog signals
(three phases and one neutral or residual value), either voltage or current, see figure
281
and figure 282 . SMAI outputs give information about every aspect of the 3ph analog
signals acquired (phase angle, RMS value, frequency and frequency derivates etc. – 244
values in total). The BLOCK input will force all outputs to value zero.
System phase rotation and frequency are defined using the PhaseRotation and Frequency
settings in the primary system values PRIMVAL function. Logic 1 in the REVROT input
to the SMAI function means that the phase rotation is changed relative to the set
PhaseRotation in PRIMVAL.
The output signal AI1 to AI4 are direct output of the, in SMT, connected input to GRPx_A,
GRPxB, GRPxC and GRPx_N, x=1-12. AIN is always calculated residual sum from the
