WARNING
Read this entire manual and all other publications pertaining to the work to be performed before in-
stalling, operating, or servicing this equipment. Practice all plant and safety instructions and precau-
tions. 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.

Table 1-1: Manual - overview
Intended Use The unit must only be operated in the manner described by this manual. The prerequisite for a
proper and safe operation of the product is correct transportation, storage, and installation as well as careful oper-
ation and maintenance.
NOTE
This manual has been developed for a unit fitted with all available options. Inputs/outputs, functions,
configuration screens, and other details described, which do not exist on your unit, may be ignored.
The present manual has been prepared to enable the installation and commissioning of the unit. Due to
the large variety of parameter settings, it is not possible to cover every combination. The manual is
therefore only a guide. In case of incorrect entries or a total loss of functions, the default settings may
be taken from the list of parameters enclosed in the configuration manual 37391.

Interface Overview
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The easYgen-1000 provides the following communication interfaces:
Serial interface (DPC)
LeoPC1 or Modbus Protocol
CAN interface
CANopen, CAN CAL, or CAN J1939 Protocol
NOTE
ECU data in J1939 format may be sent simultaneously with data in CANopen format on the same bus.
However, the baud rate must be the same.
Figure 1-1: Interface overview
WARNING
When connecting the direct configuration interface, the Woodward DPC with RJ45 connector must be
used. Failure to do so may destroy the unit.

Figure 1-2: Interface overview - serial interface
Modbus Half/Full Duplex Application
NOTE
Not every RS-232/RS-485 converter is suitable for this application when using more than one easYgen
because the converter has to control the data of the connected easYgen units.
The following model of the company Amplicon meets this requirements: Magic 485F9
This converter has also been verified for single unit applications.
Please refer to the manufacturer's homepage for further information about the suitable Amplicon RS-
485/RS-232 converter under http://www.amplicon.co.uk.

Characteristics of the CAN interface used by Woodward:
Standard: Compatible with ISO 11898
Electrically isolated: Isolation voltage 1,500 VDC
NOTE
Please note that the CAN bus must be terminated with an impedance which corresponds to the wave
impedance of the cable (e.g. 120 Ohm, ¼ W). The CAN bus is terminated between CAN-H and CAN-L.

Data Telegrams
Interface Monitoring
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
It is possible to monitor the interface for received data. Refer to the configuration manual for more information
about this monitoring function.
Transmit Telegram
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The transmit telegram provides all measuring and status data of the easYgen. The data have different addresses
and will be transmitted in the respective format depending on the selected interface.
Modbus
Data transmission in Modbus format is performed in the order of the transmit telegram (refer to Appendix A:
Transmission Telegram on page 41). The data addresses may be taken from the respective column of the transmit
telegram.
CAN (CAL)
The easYgen sends its data via cyclic CAN messages. If a GW 4 is used, the baud rate must be configured to
125 kBaud.
NOTE
Instead of using a GW 4, a CAN to USB (or RS-232) converter may be used.
CANopen
Using the mapped objects, which are described in detail starting on page 25, enables you to send data by setting
the object ID 2C76h on the basis of the CANopen protocol.
This document contains tables of further mapped objects, which may be configured in refer to Appendix A:
Transmission Telegram on page 41.
NOTE
When using the mapped objects listed in the appendix instead of the complete transmit telegram, the
refresh rate of the single messages may be reduced.
