MainsPro Reference Guide
Range: 0..999 V
0 = OFF, the positive sequence undervoltage is disabled
Default setting: 0 = OFF
V> neg, A.V> neg [V]
Threshold of the negative sequence overvoltage (angle asymmetry method).
Range: 0..999 V
0 = OFF, the negative sequence overvoltage is disabled
Default setting: 0 = OFF
dU del, A.dU del [s]
Delay of the voltage unbalance (amplitude asymmetry) protection.
Range: 0,00..600,00 s
Default setting: 2,50 s
f <>, A.f <>
f>, f>>, f<, f<<, A.f>, A.f>>, A.f<, A.f<< [Hz]
Threshold of 1st and 2nd stage overfrequency and 1st and 2nd stage underfrequency protection,
respectively.
Range: 45,00..65,00 Hz
0 = OFF, the appropriate stage of frequency protection is not enabled
Default setting:
f> 51,50 Hz
f< 47,50 Hz
f>>, f<< 0 (OFF)
f> del, f>> del, f< del, f<< del, A.f> del, A.f>> del, A.f< del, A.f<< del [s]
Delay of the appropriate stage of the frequency protection.
Range: 0,00..600,00 s
Default setting:
f> Del 1,00s
f>> Del 0,10s
f< Del 4,00 s
f<< Del 0,10 s
Rstf>,f>> [%f>]
Frequency level at which the protection activates again after a trip caused by overfrequency. The
TRIP status will be terminated.
Range: 90,0 – 100,0 %f>
0 = OFF, the reset threshold is not activated
Default setting: 100,0 %f>
Rstf<,f<< [%f<]
Frequency level at which the protection activates again after a trip caused by underfrequency. The
TRIP status will be terminated.
Range: 100,0 - 110,0 %f<
0 = OFF, the reset threshold is not activated
Default setting: 100,0 %f<
