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 301 and figure 302. 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 if BLOCK is TRUE (1).
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.
