The " ASY" potentiometer is concerned with the asymmetry function between phases. You can set the percentage between 5% and 15 % of the default voltage value. If the voltage on one phase falls under the specified value, the relay will give a signal.
The difference between this function and the under voltage function is that the under voltage has a higher range. It considers the voltage as a total but it doesn't consider the asymmetry between phase waves.
