Alarm digital output

The activation of the alarm can be high or low depending on how the

ON and OFF parameters have been set, as per the following table:

FFO-NO

SUTATSSEULAV

EPYTMRALA

FFONOHGIH

FFO<NOWOL

Where: Vmax is the max. value among VL1-N, VL2-N, VL3-N

Vmin is the min. value among VL1-N, VL2-N, VL3-N

Vavg is the average: (VL1-N, VL2-N, VL3-N)/3

Vmax - Vmin

Vavg

always without sign. The “L” or “C” type are displayed with the

PF phase variables. The total system “var’s” are obtained by

summing algebraically the single phase “var’s” ( “L” type “var’s”

are considered positive, “C” type “var’s” are considered nega-

tive). The system’s PF shows the “L” or “C” sign depending on

the result of the algebraic sum of the single phase “var’s”.

What is ASY

The ASY variable allows the user to control the symmetry of

the delta voltages (for systems without neutral) and star

voltages (for systems with neutral). The variable is calculated

according to the following formula:
