RstV>,V>> [%V>]
Voltage level at which the protection activates again after a trip caused by overvoltage. The TRIP status will
be terminated. The setpoint is set in percentage of overvoltage threshold. In case the nominal voltage is 230
V and the overvoltage threshold is 250 V, the hysteresis limit for default setting 96 %V> is 240 V. It means that
voltage must drop under 240 V to reset the fault.
Range
90 - 100 %V>
0
= OFF, the reset threshold is not activated
Default setting
100 %V>

RstV<,V<< [%V<]
Voltage level at which the protection activates again after a trip caused by undervoltage. The TRIP status will
be terminated. The setpoint is set in percentage of undervoltage threshold. In case the nominal voltage is 230
V and the undervoltage threshold is 200 V, the hysteresis limit for default setting 104 %V> is 208 V. It means
that voltage must get over 208 V to reset the fault.
Range
100 - 110 %V<
0
= OFF, the reset threshold is not activated
Default setting
100 %V<

12.1.3 Group: dU, A.dU
V unb, A.V unb [V]
Threshold of the voltage unbalance (amplitude asymmetry). The value corresponds with the maximum
difference between highest and lowest RMS phase voltage of the 3-phase system.
Range
0.0..100.0 %Un
0
= OFF, the amplitude asymmetry is disabled
Default setting
0.0 %Un = OFF

V< pos, A.V< pos [V]
Threshold of the positive sequence undervoltage (angle asymmetry method).
Range
0.0..100.0 %Un
0
= OFF, the positive sequence undervoltage is disabled
Default setting
0.0 %Un = OFF
