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 (overtemperature, 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 governor(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 damage 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.

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 operation 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 Parameter List 37431 or from ToolKit and the respective *.SID file.

Chapter 2.
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 easily as synthetics.
3.
Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam cups, cigarette packages, cellophane wrappers, vinyl books or folders, plastic bottles, etc.) away from the control, modules, and work
area as much as possible.
4.
Opening the control cover may void the unit 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:
• Ensure that the device is completely voltage-free (all connectors have to be disconnected).
• 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 cabinet, place it in the
antistatic protective bag.
CAUTION
To prevent damage to electronic components caused by improper handling, read and observe the precautions in Woodward manual 82715, Guide for Handling and Protection of Electronic Controls, Printed
Circuit Boards, and Modules.

Marine Usage (Pending)
CAUTION
The following notes are very important for marine usage of the easYgen genset control and have to be
followed.
Application
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The easYgen-2000 Series has no internally isolated power supply.
For marine applications an EMI filter (i.e. SCHAFFNER - FN 2070-3-06) must be connected ahead of the power
supply input.
To meet the functional safety requirements of the application, the rules of marine classification independent protective devices must be applied.

2.
Remove terminals
Loosen the wire connection terminal screws on the back of the unit and
remove the wire connection terminal strip if required.
3.
Insert screws in clamps
Insert the four clamping screws into the clamp inserts from the shown
side (opposite of the nut insert) until they are almost flush. Do not completely insert the screws into the clamp inserts.
4.
Insert unit into cutout
Insert the unit into the panel cutout. Verify that the unit fits correctly in
the cutout. If the panel cutout is not big enough, enlarge it accordingly.
5.
Attach clamp inserts
Re-install the clamp inserts by tilting the insert to a 45° angle. (1) Insert
the nose of the insert into the slot on the side of the housing. (2) Raise the
clamp insert so that it is parallel to the control panel.
6.
7.
Tighten clamping screws
Tighten the clamping screws (1) until the control unit is secured to the

NOTE
If L1,L2 or L3 are connected to PE or N the single reactive powers VL1-I1, VL2-I2 and VL3-I3 cannot be
calculated correctly. So the overall reactive power does not fit. The apparent power is calculated out of
the reactive power and cannot be correct too.
The at all active power and the single currents are calculated all the time correct.

For different voltage systems, different wiring terminals have to be used.

Power Factor Definition
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The phasor diagram is used from the generator's view. Power factor is defined as follows.
Power Factor is defined as a ratio of the real power to apparent power. In a purely resistive circuit, the voltage
and current waveforms are instep resulting in a ratio or power factor of 1.00 (often referred to as unity). In an inductive circuit the current lags behind the voltage waveform resulting in usable power (real power) and unusable
power (reactive power). This results in a positive ratio or lagging power factor (i.e. 0.85lagging). In a capacitive
circuit the current waveform leads the voltage waveform resulting in usable power (real power) and unusable
power (reactive power). This results in a negative ratio or a leading power factor (i.e. 0.85leading).
Inductive: Electrical load whose current waveform lags
the voltage waveform thus having a lagging power factor. Some inductive loads such as electric motors have a
large startup current requirement resulting in lagging
power factors.
© Woodward
Capacitive: Electrical load whose current waveform
leads the voltage waveform thus having a leading power factor. Some capacitive loads such as capacitor
banks or buried cable result in leading power factors.

Control: If the control unit is equipped with a power factor controller while in parallel with the utility:
A voltage lower "-" signal is output as long as the
measured value is "more inductive" than the reference
set point
Example: measured = i0.91; set point = i0.95
A voltage raise "+" signal is output as long as the
measured value is "more capacitive" than the reference
set point
Example: measured = c0.91; set point = c0.95

Discrete Input DI01 "Emergency Stop" is only a signaling input. This input may only be used to signal
that an external emergency stop button has been actuated. According to EN 60204, this input is not
approved to be used as the emergency stop function. The emergency stop function must be implemented external to the control and cannot rely on the control to function properly.

Discrete Inputs: Operation Logic
Discrete inputs may be configured to normally open (N.O.) or normally closed (N.C.) states. In the state N.O., no
potential is present during normal operation; if an alarm is issued or control operation is performed, the input is
energized. In the state N.C., a potential is continuously present during normal operation; if an alarm is issued or
control operation is performed, the input is de-energized.
The N.O. or N.C. contacts may be connected to the signal terminal as well as to the ground terminal of the discrete input. See previous chapter Discrete Inputs: Signal on page 48 for details.

CAUTION
The discrete output "Ready for operation OFF" must be wired in series with an emergency stop function. This means that it must be ensured that the generator circuit breaker is opened and the engine is
stopped if this discrete output is de-energized. We recommend to signal this fault independently from
the unit if the availability of the plant is important.

CAN Bus Topology
NOTE
Please note that the CAN bus must be terminated with a resistor, which corresponds to the impedance
of the cable (e.g. 120 Ohms, 1/4 W) at both ends. The termination resistor is connected between CAN-H
and CAN-L.
Figure 6-61: Interfaces - CAN bus - termination
Troubleshooting Possible CAN Bus Problems
If data is not transmitting on the CAN bus, check the following for common CAN bus communication problems:
• A T-structure bus is utilized
• CAN-L and CAN-H are interchanged
• Not all devices on the bus are using identical Baud rates
• Terminating resistor(s) missing
• The configured baud rate is too high for bus length
• The CAN bus cable is routed in close proximity with power cables
Woodward recommends the use of shielded, twisted-pair cables for the CAN bus (i.e.: Lappkabel Unitronic
LIYCY (TP) 2×2×0.25, UNITRONIC-Bus LD 2×2×0.22).
Maximum CAN Bus Length
The maximum length of the communication bus wiring is dependent on the configured Baud rate. Refer to Table
6-47 for the maximum bus length (Source: CANopen; Holger Zeltwanger (Hrsg.); 2001 VDE VERLAG GMBH,
Berlin und Offenbach; ISBN 3-8007-2448-0).

Table 6-47: Maximum CAN bus length
The maximum specified length for the communication bus wiring might not be achieved if poor quality wire is
utilized, there is high contact resistance, or other conditions exist. Reducing the baud rate may overcome these issues.

DPC - Direct Configuration Cable
The easYgen provides a Service Port for connecting a computer via the DPC (direct configuration cable). The
configuration interface is the RJ45 socket on the side of the easYgen housing.
NOTE
The connection cable delivered with the DPC must be used between DPC and easYgen to ensure proper functionality of the easYgen. An extension or utilization of different cable types for the connection
between easYgen and DPC may result a malfunction of the easYgen. This may possibly result in damage to components of the system. If an extension of the data connection line is required, only the serial
cable (RS-232) between DPC and laptop/PC may be extended. It is recommended to use an industry
standard cable for this.
NOTE
For a continuous operation with the direct configuration cable DPC (e.g. remote control of the easYgen), it is required to use at least revision F (P/N 5417-557 Rev. F) of the DPC. When using a DPC of an
earlier revision, problems may occur in continuous operation. It is recommended to use an industry
standard serial (RS-232) cable to connect the DPC with the laptop/PC for continuous operation. The
shield connector (6.3mm tab connector) at the DPC of revision F (P/N 5417-557 Rev. F) and above must
be connected to ground.

Useful Information
Connecting 24 V Relays
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Interferences in the interaction of all components may affect the function of electronic devices.
One interference factor is disabling inductive loads, like coils of electromagnetic switching devices. When disabling such a device, high switch-off induces voltages may occur, which might destroy adjacent electronic devices
or result interference voltage pulses, which lead to functional faults, by capacitive coupling mechanisms.
Since an interference-free switch-off is not possible without additional equipment, the relay coil is connected
with an interference suppressing circuit.
If 24 V (coupling) relays are used in an application, it is required to connect a protection circuit to avoid interferences. Figure 9-1 shows the exemplary connection of a diode as an interference suppressing circuit.
