Mains <V
[%]
Threshold for mains undervoltage. All three phases are checked. Minimum voltage out of three phases
is used.
Step:
1% of nominal voltage
Range:
50%
– 150 (Mains >V)%
Hint:
Over- and undervoltage protection is evaluated according to
setting.
3Ph4Wire and 3Ph3Wire connections are evaluated according to Ph-Ph nominal voltage (NomVolts
Ph-Ph) and Split Phase and Mono Phase connections are evaluated according to Ph-N nominal
voltage (NomVolts Ph-N).
Hint:
To evaluate Mains > V and Mains < V the controller has implemented additional hysteresis
If “Mains <V” <= 90% then hysteresis for “Mains<V” = ±4%
If “Mains >V” >= 110% then hysteresis for “Mains>V” = ±4%
If “Mains <V” >90% then hysteresis for Mains<V is calculated as 40% form (100 – “Mains<V”)
If “Mains>V” <110% then hysteresis for “Mains>V” is calculated as 40% from (100 – “Mains>V”)

Mains >Freq
[%]
Threshold for mains overfrequency. All three phases are checked. Maximum out of three is used.
Step:

Range:
50 (Mains <Freq)
– 150.0%
Mains <Freq
[%]
Threshold for mains underfrequency. All three phases are checked. Maximum out of three is used.
Step:
0.1% of Nominal frequency
Range:
50%
– 150.0(Mains >Freq)%
Mains Freq Del
[s]
Delay for mains underfrequency and overfrequency
Step:

– 60.0 s
MCB Logic
[CLOSE-ON / CLOSE-OFF]
The set point influences the behavior of the output MCB CLOSE/OPEN
CLOSE-ON: When the output MCB CLOSE/OPEN is closed
– MCB should be closed.
CLOSE-OFF: When the output MCB CLOSE/OPEN is closed
– MCB should be opened.
