2 The easYgen supports two types of generators:
n

[Synchronous] The unit provides all functions which are needed for synchronous generator
applications. Isolated and mains parallel operation is supported.
Asynchronous The unit provides the special function of the asynchronousos generator with:

Notes
The asynchron mode is not recommended for emergency power applications.
2 50 / 60 Hz The rated frequency of the system is used as a reference figure for all fre‐
quency related functions, which use a percentage value, like frequency moni‐

The speed is regulated with the speed signal from the MPU or J1939/
CAN input (as long as the GCB is open).
The closing of the GCB is executed, if the speed is within the corre‐
sponding frequency range of the generator operating window. The
voltage and phase angle is ignored in this case.
The generator monitoring (under/over frequency and under/overvoltage)
is switched off, until the generator breaker is closed.
After opening the GCB, under/over frequency and under/overvoltage
monitoring is switched off again.
The Frequency/MPU speed plausibility monitoring is only active, if the
GCB is closed.
The synchroscope is not displayed in the asynchronous modus.
