STATYS 200-1000A - Ref.:OPMSTA200910-GB_06
asYnchronous transFer
Automatic asynchronous transfer occurs only if it is authorised by the software conguration (standard factory con-
guration, advanced parameters see §10) and if the sources S1 and S2 are not synchronised, e.g. their phase de-
viation exceeds the tolerance window. In this case, switching the source may produce a signicant phase variation
during the changeover.
This type of transfer allows for automatic load changeover between sources which are not permanently controlled,
or which are unusually out of phase, thereby maximising the security of the power supply.

autoMatic restart Function
Following the total unavailability of both sources and if STATYS is in conduction state on one of the two sources, an
automatic restart and conduction occurs on the return to one of the 2 sources.
The supply is re transferred automatically onto the preferred source as soon as this source becomes available.
The automatic restart function is congurable and is set to OFF by default.
5. 4.
overload oPeration
The STATYS overload control is based on the principle of lling a reservoir more or less rapidly, depending on the
measured load rate.
Each STATYS string has its own reservoir.
When STATYS is in overload, an “OVERLOAD ALARM” message appears and the “GENERAL ALARM” is triggered.
