The LS-5 application mode
A02
opens a wide range of applications and requires more
e󰈠ort to con󰈡gure the whole easYgen – LS-5 system.
The sections below explain some of the terms and concepts required in understanding
these more complex applications.
Segment number
A segment is de󰈡ned as a section of the bus, feeder or interconnection, which cannot
electrically be isolated to a smaller section and is connected to a circuit breaker or an
isolation switch which is operated or supervised by an LS-5.
A transformer is not considered as a segment or a point of isolation. Each segment,
feeder, or interconnection must be assigned a number that is unique to that segment.
The LS-5x2 in CBA/CBB mode manages 3 segments:
• System A segment
• Load segment
• System B segment
CBA (Mains breaker)
The frequency and voltage are solid. A segment number is needed. The 󰈡rst breaker on
the mains side is the CBA.
The LS-5 is always connected with measurement system A on the mains side. The setting
"Mains connection" is always set on "System A". The system A measurement gets the
mains segment number.
CBB (Group breaker)
The LS-5x2 is always connected with measurement system B on the group breaker side.
The setting "Mains connection" is always set on "System A". The system B measurement
gets the busbar segment number.
Generator
The frequency and voltage are variable. A segment number is not needed.
Device number (control number)
All connected control units must be con󰈡gured with a unique device number (control
number). Hence the units are clear de󰈡ned in their function and location.
The numbers 1 to 32 are reserved for the easYgen(s) (easYgen "Device number"), the
numbers 33 to 64 are reserved for the LS-5 (parameter
1702).
CAN bus Node-ID number
To communicate via the CAN bus it is necessary to con󰈡gure all connected controls with a
unique CAN bus Node-ID number (parameter 8950). Usually the same number like the
device ID number is taken.
