• The easYgen recognizes through the LS-5 system the active
segment number.
• Connection to mains (MCB is closed) is recognized via the LS-5
system, if one or more “Mains”-LS-5 are available.
• The close and open commands for the single LS-5 breakers are
usually not generated in the easYgen.
•
Mains voltage and current is usually not connected at the
easYgen.
Exception: VDE-AR-N 4105 (refer to chapter VDE-AR-N 4105

• Run-up synchronization, acting on the GCB, is possible.

One or more easYgen with one LS-5x2 unit, acting on the GGB and
on the MCB in a 󰈡xed application. Multiple isolated and/or mains
parallel operation. The same handling as in the GCB/GGB/MCB
mode, but the GGB and MCB are operated by one LS-5x2.
This application mode provides the following functions:
• Handling of the GCB (dead bus closure, synchronization, open)
initiated by start command in AUTO or individually in MAN
mode.
•
Handling of the GGB (dead bus closure, synchronization, open)
initiated by start command in AUTO or individually in MAN
mode according to the rule of the GCB/GGB/MCB mode.
•
Handling of the MCB (dead bus closure, synchronization, open)
in AUTO and MANUAL according to the rules of the
GCB/GGB/MCB mode.
•
Measuring and monitoring of generator values (voltage,
frequency, phase rotation, current and power).
•
Measuring of generator busbar values (voltage, frequency)
• Indicating of mains values (voltage, frequency, phase angle)
sent from the LS-5x2.
•
Indicating of active and reactive power at the interchange
point sent from LS-5x2.
•
Regulating Import/Export power with active and reactive power
sent from LS-5x2.
•
Run-up synchronization, acting on the GCB or GCB/GGB, is
possible.

Setup Stand-Alone Applications (Mode A01)
Overview
The LS-5, con󰈡gured to application mode
A01
('Single LS-5'), runs as an independent unit
and does not expect any other unit on the CAN bus.
The idea of this mode is to use the LS-5x2 as a simple change over control (ATS)
controlled by discrete inputs or to run it together with a PLC. The PLC receives all
measurement values (voltages, current, power, phase angle) via communication interface
to run closed loop synchronization. Each breaker can be individually opened and closed,
whereby the LS-5 recognizes to “close only” or to synchronize.
