Ground fault 1 Generator ground current, limit value 1
3263 The measured or calculated ground current has exceeded the limit value 1 for the generator ground cur‐
rent for at least the configured time and does not fall below the value of the hysteresis.
Ground fault 2 Generator ground current, limit value 2
3264 The measured or calculated ground current has exceeded the limit value 2 for the generator ground cur‐
rent for at least the configured time and does not fall below the value of the hysteresis.
Inv. time overcurr. Generator inverse time-overcurrent
4038 Current monitoring with tripping time depending on the measured current. The higher the current is the
faster the tripping time according to a defined curve. According to IEC 255 three different characteristics
are available: normal, highly, and extremely inverse.
Mains decoupling Mains decoupling is initiated
3114 One or more monitoring function(s) considered for the mains decoupling functionality has triggered.
Mains overfreq. 1 Mains overfrequency, limit value 1
2862 The mains frequency has exceeded the limit value 1 for mains overfrequency for at least the configured
time and does not fall below the value of the hysteresis.
Mains overfreq. 2 Mains overfrequency, limit value 2
2863 The mains frequency has exceeded the limit value 2 for mains overfrequency for at least the configured
time and does not fall below the value of the hysteresis. Triggering this monitoring function causes the
mains decoupling function to trigger.
Mains overvoltage 1 Mains overvoltage, limit value 1
2962 The mains voltage has exceeded the limit value 1 for mains overvoltage for at least the configured time
and does not fall below the value of the hysteresis.
Mains overvoltage 2 Mains overvoltage, limit value 2
2963 The mains voltage has exceeded the limit value 2 for mains overvoltage for at least the configured time
and does not fall below the value of the hysteresis. Triggering this monitoring function causes the mains
decoupling function to trigger.
Mains phase shift Mains phase shift
3057 A mains phase shift, which has exceeded the configured limit, has occurred. Triggering this monitoring
function causes the mains decoupling function to trigger.
Mains df/dt Mains df/dt (ROCOF)
3106 A mains df/dt, which has exceeded the configured limit, has occurred. Triggering this monitoring function
causes the mains decoupling function to trigger.
Mains underfreq. 1 Mains underfrequency, limit value 1
2912 The mains frequency has fallen below the limit value 1 for mains underfrequency for at least the configured
time and has not exceeded the value of the hysteresis.
Mains underfreq. 2 Mains underfrequency, limit value 2
2913 The mains frequency has fallen below the limit value 2 for mains underfrequency for at least the configured
time and has not exceeded the value of the hysteresis. Triggering this monitoring function causes the
mains decoupling function to trigger.
Mains undervoltage 1 Mains undervoltage, limit value 1
3012 The mains voltage has fallen below the limit value 1 for mains undervoltage for at least the configured time
and has not exceeded the value of the hysteresis.
