WARNING!
Read this entire manual and all other publications
pertaining to the work to be performed before
installing, operating, or servicing this equipment.
Practice all plant and safety instructions and pre‐
cautions. Failure to follow instructions can cause
personal injury and/or property damage.
The engine, turbine, or other type of prime mover
should be equipped with an overspeed (overtem‐
perature, or overpressure, where applicable) shut‐
down device(s), that operates totally independently
of the prime mover control device(s) to protect
against runaway or damage to the engine, turbine,
or other type of prime mover with possible personal
injury or loss of life should the mechanical-
hydraulic governor(s) or electric control(s), the
actuator(s), fuel control(s), the driving mecha‐
nism(s), the linkage(s), or the controlled device(s)
fail.
Any unauthorized modifications to or use of this
equipment outside its specified mechanical, elec‐
trical, or other operating limits may cause personal
injury and/or property damage, including damage
to the equipment. Any such unauthorized modifica‐
tions: (i) constitute "misuse" and/or "negligence"
within the meaning of the product warranty,
thereby excluding warranty coverage for any
resulting damage, and (ii) invalidate product certifi‐
cations or listings.
CAUTION!
To prevent damage to a control system that uses
an alternator or battery-charging device, make
sure the charging device is turned off before dis‐
connecting the battery from the system.
Electronic controls contain static-sensitive parts.
Observe the following precautions to prevent
damage to these parts.
– Discharge body static before handling the con‐
trol (with power to the control turned off, con‐
tact a grounded surface and maintain contact
while handling the control).
– Avoid all plastic, vinyl, and Styrofoam (except
antistatic versions) around printed circuit
boards.
– Do not touch the components or conductors on
a printed circuit board with your hands or with
conductive devices.

2 Introduction
This brief manual must be used together with the
standard manuals
The following standard manuals are required to
install, commission, and operate the
easYgen-3500XT Packages P1, P2 with Option
K51 and the Group Controller:
– easYgen-3000XT Series Manual (No. 37580
and 37581)
– GC3000XT Group Controller (No. 37689)
The following functions described in the
easYgen-3000XT Series Manual are not supported
by K51:
– Localization tool
– LDSS without GC
– J1939 ADEC ECU9: rapid start, droop selec‐
tion
– J1939 SPNs: 3251, 3699, 3702
– AVR control
2.1 Overview
The easYgen-3500XT Packages P1, P2 with Option K51 are dedi‐
cated devices for the interaction with the Group Controller
GC3400XT (GC).
2.2 Description
Only the easYgenXT K51 works together with the Generator Group
Controller GC3400XT.
For detailed description of the Group Controller (GC) functionality,
please refer to the Group Controller manual.
The K51 easYgen derivate has included special functions to be
able to operate with the Group Controller GC3400XT-P1. The K51
device provides some special parameters which are needed to
work with the GC device. These parameters are by default
adjusted so that the usual GC functions are provided, but can be
configured so that the K51 device can work as a standard
easYgen, with the exception of the LDSS feature.

3 Additional Functionality
3.1 Operation with the Group Controller
To run the K51 easYgen together with the Group Controller, the
parameter “GC mode” (7950 Ä p. 15) must be configured to “On”
(which is the default option).
If the GC mode is enabled:
nParameter “Application mode” (3444) is fixed to “GCB/LS5.”
This is because some functions of the Group Controller bear
resemblance to Woodward's LS5 device. (For this reason, in
some screens "LS5" will appear, even though there is no LS5.)
nParameter "Load share interface” (9924 Ä p. 16) is hidden,
therefore, parameter "Load share interface GC mode" (9948)
becomes active and defines the communication interfaces
between the easYgens and their Group Controller. This load-
share interface to the GC is selectable as CAN3, Ethernet A or
redundant CAN3/Ethernet A.
nThe K51 easYgens share data for load sharing, “LS5”, diag‐
nostic and “Load dependent start/stop” (LDSS) with the Group
Controller.
nThe range of the parameter “Device number” (1702) is
restricted to 1-31. The Group Controller is fixed on device
number 32.
nIf the Group Controller works with a generator group circuit
breaker (GGB), the GGB status can be indicated in the “One
Line Diagram” of the K51 easYgen if parameter “GC Online
diagram with GGB” (4147 Ä p. 16) is configured to “On”
3.2 Application
3.2.1 Inhibit uncoordinated dead bus closure GCB
WARNING!
To avoid uncoordinated GCB dead bus closure
there are some fixed internal precautions (like in
the standard easYgen) and some precautions
which must be taken by configuring the LogicsMa‐
nager's "Inhibit dead bus closure GCB”. Logi‐
csManager is preconfigured by default as
described below.
Consider the following precautions:
nThe easYgens which do not recognize their Group Controller
must inhibit their GCB dead busbar closure. For this reason "
02.40 Ä p. 16 GC not recognized" is assigned to the Logi‐
csManager "Inhibit dead bus closure GCB” (15161 Ä p. 9)
nThe easYgens which recognize a dead generator busbar (Gen‐
erator Group is dead), with all the breakers acting on this
busbar being open, negotiate the dead busbar closure with all
generator group members (the easYgen with the smallest
device number has the highest priority). Where the GC wants
to effect the dead bus closure, too, it must inhibit all the easY‐
gens from closing their breakers. For this reason the Group
Controller is transmitting the command variable “02.41 GC
Inhibit DBCL GCB”, which is assigned to the LogicsManager
"Inhibit dead bus closure GCB” (15161 Ä p. 9).

nThe K51 easYgenXT (GC mode enabled) which has triggered
the "Missing easYgen alarm" delays its dead bus closure
depending on its device number. This is cascaded through:
(Device number easYgen) x 0.5s. The GC dead bus closure is
not delayed, if the "Missing easYgen alarm" is triggered. This
procedure cannot prevent a wrong dead busbar closure, but it
minimizes the probability of this happening.
nThe easYgen which recognizes at least one easYgen with a
closed GCB in its group, inhibits the GCB dead bus bar clo‐
sure.

3.2.2 Droop configuration
To avoid instable behavior of the voltage and frequency control if a
load sharing member is missing, the configuration of the K51 must
be adapted. In the K51, the LogicsManager's “12904 Ä p. 9
Freq. droop act.” and “12905 Ä p. 9 Volt. droop act.” are
changed (by default) in comparison to the standard easYgen
device:

3.2.3 Home Screen
If GC mode is on, it is possible to show the mains data measured
by the Group Controller “Mains (GC)” like in the screen below. If
this is wished, parameter “4103 Home screen data” must be con‐
figured to “Generator/LS5” .
Additionally, the state of the GGB controlled by the Group Con‐
troller can be shown if parameter “4147 Ä p. 16 GC One line dia‐
gram with GGB” is configured to “On”.

3.3 Communication Management / Diagnostics
Like in the standard easYgen, there is the function of Communica‐
tion Management. (For details refer to easYgen manual chapter on
Communication Management). Option K51 provides different
screens for the easYgen and the Group Controller diagnostics.
In the Group Controller mode, the load share interfaces can be
CAN, Ethernet A or redundant CAN/Ethernet A. For this reason,
there are additional indications “CAN” and “A” (in Toolkit “Only NW
CAN”, “Only NW A”). “Monitored easYgen” indicates the number of
easYgens which are taught in. Even if the Group Controller is a
member of the load share (device 32), it is not added to “Monitored
easYgen”. (The screens are located under “Status Menu / Next
page / Multi-unit Diagnostic devices” 1st and 2nd screen.)
