6.5.1
Introduction
This chapter shall inform about the possibilities how the LS-522 can be used in
cooperation with the easYgen-3000(XT) to match the VDE-AR-N 4105 mains directive
requirement. The easYgen-3000(XT) and the LS-522 are products which contain the mains
decoupling monitoring. Through the demanded one failure security in the system both
devices must be involved. In most cases the LS-522 acts together with an
easYgen-3500(XT), in few cases with an easYgen-3200(XT). Some typical applications are
shown below. For more information please refer to the according FNN VDE-AR-N 4105
document. To help in these speci󰈡c applications Woodward provides also an application
note with more details and how to con󰈡gure the devices.
For further information please refer to application mode "DE37671
easYgen-3000_LS5_VDE-AR-N 4105".
6.5.2
One easYgen-3500XT (Mode GCB/L-GGBMCB) with LS-522 as
separate mains decoupling device
The easYgen-3500(XT) performs an island and mains parallel operation. The easYgen and
the LS-522 act simultaneously as protection devices for mains decoupling. The
easYgen-3500(XT) operates the GCB according to the application mode 'GCB/L-GGBMCB'.
The LS-522 contains the counter part of mains decoupling function in regards of FNN VDE-
AR-N 4105 needs. It operates the GGB and the MCB according to the application mode 'L-
GGBMCB'.
This mode is only supported by the easYgen-3500XT version 1.13 and higher.
