WARNING
Read this entire manual and all other publications pertaining to the work to be performed before instal-
ling, operating, or servicing this equipment. Practice all plant and safety instructions and precautions.
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 (overtempera-
ture, or overpressure, where applicable) shutdown 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 gov-
ernor(s) or electric control(s), the actuator(s), fuel control(s), the driving mechanism(s), the linkage(s),
or the controlled device(s) fail.
Any unauthorized modifications to or use of this equipment outside its specified mechanical, electrical,
or other operating limits may cause personal injury and/or property damage, including damage to the
equipment. Any such unauthorized modifications: (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 certifications 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 disconnecting the battery from the system.
Electronic controls contain static-sensitive parts. Observe the following precautions to prevent dam-
age to these parts.
•
Discharge body static before handling the control (with power to the control turned off, contact 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.

Safety Precautions
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
WARNING
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
•Only qualified workers should install this equipment. Such work should be performed only after read-
ing this entire set of instructions.
•NEVER work alone.
•Before performing visual inspections, tests, or maintenance on this equipment, disconnect all
sources of electric power. Assume that all circuits are live until they have been completely de-
energized, tested, and tagged. Pay particular attention to the design of the power system. Consider all
sources of power, including the possibility of backfeeding.
•Apply appropriate personal protective equipment and follow safe electrical practices.
•Turn off all power supplying the equipment in which the LSG is to be installed before installing and
wiring the LSG.
•Always use a properly rated voltage sensing device to confirm that power is off.
•Beware of potential hazards, wear personal protective equipment, and carefully inspect the work area
for tools and objects that may have been left inside the equipment.
•The successful operation of this equipment depends upon proper handling, installation, and opera-
tion. Neglecting fundamental installation requirements may lead to personal injury as well as damage
to electrical equipment or other property.
Failure to follow these instructions will result in death or serious injury!
WARNING
No dead bus closure interlock between easYgen and legacy products is provided by the LSG. A clo-
sure of the easYgen or legacy product onto a dead busbar simultaneously with other controls must be
prevented by external means!
The unit does not provide any protection and in addition renders the built-in protection of the easYgen
dysfunctional!
Regulatory Notes
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
•The LSG is suitable for use in non-hazardous locations only.
•The LSG is not authorized for use in life support devices or systems.
•Wiring and installation must be in accordance with applicable electrical codes in accordance with the author-
ity having jurisdiction.
•The LSG is designed for installation into an electrical switchboard or cubical as part of a fixed installation.

Electrostatic Discharge Awareness
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
All electronic equipment is static-sensitive, some components more than others. To protect these components
from static damage, you must take special precautions to minimize or eliminate electrostatic discharges.
Follow these precautions when working with or near the control.
1. Before doing maintenance on the electronic control, discharge the static electricity on your body to ground
by touching and holding a grounded metal object (pipes, cabinets, equipment, etc.).
2. Avoid the build-up of static electricity on your body by not wearing clothing made of synthetic materials.
Wear cotton or cotton-blend materials as much as possible because these do not store static electric
charges as much as synthetics.
3. Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam cups, cup holders, cigarette
packages, cellophane wrappers, vinyl books or folders, plastic bottles, and plastic ash trays) away from the
control, the modules, and the work area as much as possible.
4. Opening the Control unit will void the warranty!
Do not remove the printed circuit board (PCB) from the control cabinet unless absolutely necessary. If you
must remove the PCB from the control cabinet, follow these precautions:
•Make sure that the unit is completely de-energized (all connectors have to be pulled off).
•Do not touch any part of the PCB except the edges.
•Do not touch the electrical conductors, connectors, or components with conductive devices or with
bare hands.
•When replacing a PCB, keep the new PCB in the plastic antistatic protective bag it comes in until you
are ready to install it. Immediately after removing the old PCB from the control unit, place it in the an-
tistatic protective bag.
WARNING
To prevent damage to electronic components caused by improper handling, read and observe the pre-
cautions in Woodward manual 82715, Guide for Handling and Protection of Electronic Controls, Printed
Circuit Boards, and Modules.
Mounting and Removal
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The enclosure provides protection against solid objects according to IP 20 classification and NEMA Type 1 rat-
ing. When mounting the enclosure observe the following rules:
•Avoid splash water and water drops
•Avoid aggressive gas, steam or liquids
•Avoid dusty environments
•Make sure there is sufficient air ventilation and clearance to other devices mounted next to the module
•Do not exceed the specified operational temperatures.
•Mount inside a sealed electrical switchboard or cubicle
•Observe applicable local regulations like EN60204 / VDE0113

Manual 37442B LSG - Load Share Gateway
© Woodward Page 11/32
Application Overview
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The LSG is available in two different types:
•Active power load share (P)
•Reactive power load share (Q)
The following figures show application examples for both LSG types (marked with P or Q).
easYgen connected to EGCP-2 (CAN/RS-485)
The easYgen devices communicate via CAN bus among each other and therefore can´t communicate directly to
EGCP-2 devices which have no CAN bus interface. The LSG is able to connect EGCP-2 and easYgen devices in
a single load share network.
easYgen (CAN)
The LSG is fixed to work as generator with address 15 and 16. For this reason it is not allowed, to set any other
easYgen device to address 15 or 16. (For further information please refer to the easYgen manuals)
EGCP-2 (RS-485)
The LSG is fixed to work as generator with address 8. For this reason it is not allowed, to set any EGCP-2 to ad-
dress 8. (For further information please refer to the EGCP-2 manuals)
CAN, RS-485 interface and power supply are isolated galvanically, so there is no need for any additional galvan-
ic isolation.
Figure 2-1: Application – EGCP-2
WARNING
Please arrange additional precautions for the dead bus closure interlock. The LSG connection doesn´t
guarantee a dead bus closure interlock.
NOTE
All easYgen devices which are allowed to perform a dead bus closure, independent of the EGCP-2,
must have a generator number <15.

Manual 37442B LSG - Load Share Gateway
Page 12/32 © Woodward
easYgen connected to GCP/MFR (CAN)
The easYgen devices communicate via CAN bus among each other with an easYgen specific protocol which dif-
fers from the GCP/MFR protocol. The LSG is able to connect GCP/MFR and easYgen devices in a single load
share network on the same CAN bus. The CAN baud rate of this mode is 125kB. For this reason the number of
devices at the CAN is limited to overall 16.
easYgen (CAN)
The LSG is fixed to work as generator with address 15 or 16. For this reason it is not allowed, to set any other ea-
sYgen device to address 15 or 16. (For further information please refer to the easYgen manuals)
GCP/MFR (CAN)
The LSG is fixed to work as generator with address 8. For this reason it is not allowed, to set any GCP/MFR to
address 8.
CAN interface and power supply are isolated galvanically, so there is no need for any additional galvanic isola-
tion.
Figure 2-2: Application – GCP/MFR
NOTE
Dead bus closure interlock
The easYgen device group (LSG) appears for the GCP/MFR devices as a GCP/MFR with generator
number 8. The GCP/MFR device group (LSG) appears for the easYgens devices as an easYgen with ge-
nerator number 16.
If there are two units which want to perform a dead bus closure, the unit with the lowest generator
number gets the permission. For this reason every device group (1x easYgen and 1x GCP/MFR) is al-
lowed to perform a dead bus closure.
WARNING
The above described note makes it necessary to arrange additional precautions for the dead bus clo-
sure interlock. The LSG connection doesn´t guarantee a dead bus closure interlock. We highly recom-
mend disabling the dead bus closure on the easYgen device group or the GCP/MFR device group and
enable dead bus closure at all GCP/MFR devices.

Manual 37442B LSG - Load Share Gateway
© Woodward Page 13/32
easYgen connected to legacy device (CAN/Analog)
The easYgen devices communicate via CAN bus among each other and therefore can´t communicate directly to
analog legacy devices which have no CAN bus interface. The LSG is able to connect analog legacy devices and
easYgen devices in a single load share network.
NOTE
Find further information’s on supported legacy devices in Chapter 5 - Configuration.
WARNING
Please arrange additional precautions for the dead bus closure interlock. The LSG connection doesn´t
guarantee a dead bus closure interlock.
There are two application scenarios possible:
•Examples A shows the applications with one LSG for all easYgen devices.
•Examples B shows the applications with one LSG for each easYgen devices.
To decide which setup is to prefer in the application, different aspects for operation and safety should be re-
garded.
CAN, Analog Line and power supply are isolated galvanically, so there is no need for any additional galvanic
isolation.
Examples A:
Active power loadshare:
On CAN (easYgen) the LSG is fixed to work as generator with address (15) / 16. For this reason it is not allowed,
to set any easYgen to address (15) / 16.
Figure 2-3: Application – analog active power
NOTE
The easYgen device reserves the address 15 and 16 by default. Address 15 is in this case not used.

Manual 37442B LSG - Load Share Gateway
Page 14/32 © Woodward
Active and
On CAN (easYgen) the LSG for active power loadsharing is fixed to work as generator with address 16 the LSG
for reactive power loadsharing to work as generator with address 15. For this reason it is not allowed, to set any
easYgen to address 15 or 16.
reactive power loadshare:

© Woodward Page 15/32
Examples B:
Active power loadshare:
On CAN (easYgen) the LSGs are fixed to work as generator with addresses 15 and 16. For this reason it is not al-
lowed, to set any easYgen devices to address 15 and 16.
In this application the easYgen must not connected via CAN
