If the mains rated voltage is 400 V, the upper voltage limit is 110 %
(of the mains rated voltage, i.e. 440 V), and the hysteresis for the
upper voltage limit is 5 % (of the mains rated voltage, i.e. 20 V), the
mains voltage will be considered as being out of the operating
limits as soon as it exceeds 440 V and will be considered as being
within the operating limits again as soon as it falls below 420 V
(440 V – 20 V).
If the rated system frequency is 50 Hz, the lower frequency limit is
90 % (of the rated system frequency, i.e. 45 Hz), and the hyste‐
resis for the lower frequency limit is 5 % (of the rated system fre‐
quency, i.e. 2.5 Hz), the mains frequency will be considered as
being out of the operating limits as soon as it falls below 45 Hz and
will be considered as being within the operating limits again as
soon as it exceeds 47.5 Hz (45 Hz + 2.5 Hz).

2 100 to 150 % The maximum permissible positive deviation of the mains voltage from the
mains rated voltage (parameter
[110 %]
This value may be used as a voltage limit switch. The conditional state of this
switch may be used as a command variable for the LogicsManager (02.09).

eter

ured here, to be considered as being within the operating limits again.
2 50 to 100 % The maximum permissible negative deviation of the mains voltage from the
mains rated voltage (parameter
[90 %]
This value may be used as a voltage limit switch. The conditional state of this
switch may be used as a command variable for the LogicsManager (02.09).
2 0 to 50 % If the mains voltage has fallen below the limit configured in param‐

ured here, to be considered as being within the operating limits again.
2 100.0 to 150.0 The maximum permissible positive deviation of the mains frequency from the
% rated system frequency (parameter
[110.0 %] This value may be used as a frequency limit switch. The conditional state of
this switch may be used as a command variable for the LogicsManager
(02.10).

easYgen-2200/2500 | Genset Control
The mains operating voltage/frequency parameters are
used to trigger mains failure conditions and activate an
emergency run.
The mains values must be within this ranges to syn‐
chronize the mains circuit breaker. It is recommended
to configure the operating limits within the monitoring
limits.
