WARNING
Read this entire manual and all other publications pertaining to the work to be performed before install-
ing, 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 ty-
pe of prime mover with possible personal injury or loss of life should the mechanical-hydraulic gover-
nor(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.

NOTE
Some parameters of the easYgen-300 series can only be configured using the Direct Configuration Ca-
ble DPC (P/N 5417-557) and a notebook/PC with the software LeoPC1. These parameters are indicated
with an L in the parameter description under Parameters starting from page 69 and can not be config-
ured at the unit directly.
The configuration with LeoPC1 via the DPC is described under Configuration Using the PC on page 66.
The DPC is not part of the easYgen-300 shipment and sold separately (P/N 5417-557).
IMPORTANT NOTE ABOUT COUNTERS

The counters for
• Operation hours
• Maintenance Interval
• Number of starts
rd
can be recalibrated with LeoPC1 and the configuration files belonging to the unit. If 3 party users are
not allowed to change these values, you can easily remove the parameters which enable changing the
counters by editing the LeoPC1 configuration files as described under Editing the Configuration File
on page 67.
The counter for
• Maintenance Interval
can also be recalibrated using the front panel. You may prevent the user from recalibrating this pa-
rameter by setting a HMI password as described under Codes on page 94.

Chapter 3.
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 performing 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 char-
ges 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 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 de-energized (all connectors must 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 with your
hands.
• When replacing a PCB, keep the new PCB in the protective antistatic 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
protective antistatic bag.
CAUTION
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.
NOTE
The unit is capable to withstand an electrostatic powder coating process with a voltage of up to 85 kV
and a current of up to 40 µA.

Installation
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
For installation into a door panel, proceed as follows:
1. Panel cut-out
Cut out the panel according to the dimensions in Figure 4-1.
2. Remove terminals
Loosen the wire connection terminal screws on the back of the unit and
remove the wire connection terminal strips if required (1).
1
3. Loosen clamping screws

2
Loosen the four clamping screws (1) until they are almost flush with the 1
clamp inserts and tilt the clamp inserts down by 45° (2) to remove them
from the housing. Do not completely remove the screws from the clamp
inserts.
4. Insert unit into cut-out

Insert the unit into the panel cut-out. Verify that the unit fits correctly in
the cut-out. If the panel cut-out is not big enough, enlarge it accordingly.
Ensure that the gasket is placed properly if used. Ensure that the paper
strip is not pinched between gasket and panel to maintain isolation.
5. Attach clamp inserts
Re-install the clamp inserts by tilting the insert to a 45° angle (1). Insert
2
the nose of the insert into the slot on the side of the housing. Raise the
clamp insert so that it is parallel to the control panel (2). 1
6. Tighten clamping screws 1

Tighten the clamping screws (1) until the control unit is secured to the
control panel (2). Over tightening of these screws may result in the clamp
inserts or the housing breaking. Do not exceed the recommended tighten- 2
ing torque of 0.1 Nm.
7. Reattach terminals
Reattach the wire connection terminal strips (1) and secure them with the
side screws. 1
Note: If the gasket is damaged, it needs to be replaced. Use only the original gasket kit (P/N 3050-1057) for re-
placement.

Voltage Measuring
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The easYgen-300 series allows the use of different voltage measuring methods for generator and mains voltage
depending on the model. These are described in the following text.
Measuring Description
method
Measurement is performed phase-neutral (WYE connected system). Phase voltages and
neutral conductor must be connected for proper calculation. The measurement, display
and protection are adjusted according to the rules for WYE or delta connected systems.
3Ph 4W Monitoring refers to the following voltages:
• VL12, VL23, and VL31, or
• VL1N, VL2N, and VL3N.
Measurement is performed phase-phase (delta connected system). Phase voltages must

be connected for proper calculation. The measurement, display and protection are ad-
3Ph 3W justed according to the rules for delta connected systems. Monitoring refers to the fol-
lowing voltages:
• VL12, VL23, VL31.
Measurement is performed for single-phase systems. The measurement, display and pro-
tection are adjusted according to the rules for single-phase systems. Monitoring refers to
1Ph 2W
the following voltages:
• VL1N.
Measurement is performed for single-phase systems. The measurement, display and pro-
tection are adjusted according to the rules for single-phase systems. Monitoring refers to
1Ph 3W
the following voltages:
• VL1N, VL3N.
Table 6-3: Voltage measuring principles
The above described voltage measuring methods are shown with appropriate wiring examples for the different
models for generator and mains voltage measuring in Figure 6-4 to Figure 6-12.
NOTE
Please note that not all measuring methods can be performed with all models of the easYgen-300 se-
ries. The methods of measurement are indicated in the wiring diagrams for the respective models.
NOTE
LeoPC1 and a DPC cable (Revision B, P/N 5417-557) are required to configure the voltage measuring
methods for all versions of the easYgen-300 series.

Phase-Phase Voltage Measuring

It is also possible to perform a phase-phase voltage measuring. The units is intended for a phase-neutral measur-
ing as described above, but may also be used for phase-phase voltage measuring. In this case, phase L2 must be
connected to the N terminal of the easYgen and the Generator rated voltage (Parameter 11) must be configured to
the phase-phase voltage.

If you select to perform a phase-phase voltage measuring, the display is still indicating a phase-neutral
voltage since the voltage is measured between terminal 33 (L1) and 35 (N).
However, if the Generator rated voltage (Parameter 11) is configured correctly, the displayed value is
the correct phase-phase voltage value.

Discrete Inputs: Operation Logic

Discrete inputs may be configured to be used for normally open (N.O) and normally closed (N.C.) contacts.
The default condition for N.O. is that the voltage signal is low. If the N.O. contact closes, the signal becomes
high and the easYgen will detect an appropriate alarm or status.
The default condition for N.C. is that the voltage signal is high. If the N.C. contact opens, the signal becomes low
and the easYgen will detect an appropriate alarm or status.
The N.O. or N.C. contacts may be connected to the signal terminal or to the ground terminal of the discrete input.
See previous chapter Discrete Inputs: Bipolar Signals on page 27 for details.

For the easYgen-300 series, the discrete inputs 1-3 are configured to a factory default and cannot be changed.
The discrete inputs 4 and 5 are freely configurable depending on the parameter "Ignore CB reply". If this pa-
rameter is set to "YES", the discrete inputs are freely configurable, and the operation logic may be configured ei-
ther to N.O. or N.C.

Possible CAN Bus Problems
If no data is transmitted on the CAN bus, check the following for common CAN bus communication problems:
• T structure bus is utilized (stub-end feeders or branch lines are not recommended)
• CAN-L and CAN-H are interchanged
• Not all devices on the bus are using identical Baud rates
• Terminating resistor(s) is/are missing
• Incorrect baud rate (too high) for length of CAN bus
• The CAN bus cable is co-routed with power cables
Woodward recommends the use of 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
6-11 for the maximum bus length (Source: CANopen; Holger Zeltwanger (Hrsg.); 2001 VDE VERLAG GMBH,
Berlin und Offenbach; ISBN 3-8007-2448-0).

Table 6-11: 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 is-
sues.
DPC - Direct Configuration Cable
NOTE
Please note that the configuration via the direct configuration cable DPC (P/N 5417-557) is possible
starting with Revision B (first delivered July 2003). If you have an older model please contact technical
sales.
NOTE
The connection cables delivered with the DPC must be used to connect between the control unit and
the computer to ensure a proper function of the easYgen. Utilization of an extension or different cable
types for the connection between easYgen and DPC can result in 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 between DPC and notebook/PC may be extended.
Unplug the DPC after configuration to ensure a safe operation!

Operation and Display

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Purpose of the Status LEDs
The easYgen has several status LEDs to indicate the operating state. The LEDs indicate the following conditions:
LED 9 (on): Mains voltage present (only easYgen-350 and 350X)
LED 9 (flashing): Mains voltage and/or frequency are not within the Breaker Closure Limits (see page 59)
LED 10 : Mains circuit breaker (MCB) closed (only easYgen-350 and 350X)
LED 11 : Generator circuit breaker (GCB) closed
12
LED (on): Generator in operation
LED 12 (flashing): Generator voltage and/or frequency are not within the Breaker Closure Limits (see page 59)
LED 13 (on): Engine in operation
LED 13 (flashing):Engine in operation, but engine monitoring delay time (see page 73) not yet expired
LED 14 : Alarm message present
LED 15 : Genset in automatic operation
LED 16 : Genset in manual operation
LED 17 : Genset stopped
A function test of all LEDs and the seven-segment display may be conducted by pressing the 7 and 8
buttons simultaneously.
Operating the easYgen

• When the easYgen control unit is powered up and the genset is not operating, LED 17 is illuminated and
the MCB is closed (only easYgen-350 and 350X).
• The control unit may be started in automatic mode or have the operation mode changed from automatic to
manual by pressing the Auto - Manual button 3 . LED 15 (automatic) or LED 16 (manual) will indi-
cate the current mode of operation by the corresponding LED being illuminated.
• The Breaker Control button 4 enables the operator to open or close the circuit breaker(s) depending on
the current state of the breaker and the control unit being in manual operation mode. This button is disabled
in automatic operation mode.
• The Start/Stop Engine button 5 will start and stop the engine when the control unit is in manual opera-
tion mode. This button is disabled when the control unit is in automatic operation mode.
• The Stop button 6 is always enabled and when pressed while in the automatic mode will shut the en-
gine down after the configured cool down period has expired. Pressing this button twice will shutdown the gen-
set immediately.
• Active alarm messages may be acknowledged with the Alarm button 2 . Alarm conditions are indicated
when LED 14 is illuminated.

• When the easYgen is in normal operation, the operator may view the monitored parameters by using the
Scroll button 1 . The monitored values will be displayed on the 7-segment display 18 (a detailed de-
scription of the displayed operating values may be found later in this manual).
Acknowledging Alarm Messages

LED 14 will flash when an alarm is active. The alarm message will be displayed in the 7-segment display 18 .
Pressing the alarm button 2
will acknowledge the alarm, reset the alarm relay (if relay is configured for
alarm input), and the LED will change from flashing to continuously illuminated. If more than one fault condi-
tion is present, the operator may display these messages by pressing the Scroll button 1 . The alarm may be
deleted by pressing and holding the Alarm button 2a second time until the LED 14 is no longer illumi-
nated. If the fault condition is still present, the LED 14 will remain illuminated and the unit stays in a locked
mode according to the appropriate alarm condition.

Configuring the easYgen

To enter the configuration mode, press the Scroll 1 and Alarm 2 buttons simultaneously. Only the pa-
rameters 00 - HMI Password, 01 - Time until horn reset and 72 - Display level are visible without entering a
password. In order to display the other parameters, the correct password must be entered in the Parameter 00 -
HMI Password. Pressing the Scroll button 1 will display the various parameters that may be changed. The
displayed values for the parameters may be changed by pressing the 7 and 8 buttons (a detailed de-
scription of the parameters begins on page 69 of this manual). If the operator presses and holds these buttons, the
rate of change for the value will increase. After the parameter has been adjusted to the desired value, enter it into
the control unit by pressing the Scroll button 1 once. After a parameter has been changed and entered into
the control unit, the operator may advance to the next parameters by pressing the Scroll button 1 a second
time. To exit the configuration mode, press the Scroll 1 and Alarm 2 buttons simultaneously again.
Display of the Operating Values

The easYgen-300 control units are able to display various measured values during operation depending on the re-
spective easYgen model. You may advance through the single value displays using the Scroll button 1 .
The values are displayed numerically, while the engineering unit, source, and phase are coded in the seven-
segment display 18 if applicable. See the example below:
Figure 7-2: 6 digit 7 segment LED display
• The first digit (counted from left) indicates what is being measured, (mains, engine, or generator). The top
horizontal segment indicates mains, the middle horizontal segment indicates engine, and the bottom hori-
zontal segment indicates generator.
• The second digit indicates the measured phase. The top segment indicates L1, the middle horizontal seg-
ment indicates L2, and the bottom horizontal segment indicates L3. If only one line is displayed for phase
measurement, a phase to neutral measurement is displayed. If two lines are displayed, a phase to phase
measure ment is shown.
• Digits 3-6 indicate what the measured value of the displayed parameter is.
• The indicators located at the top left of the first four digits of the display indicate the engineering unit of
measure to be utilized. The indicators are assigned the following engineering units of measure.
o Digit 1: Operating hours [h]
o Digit 2: Revolutions [rpm]
o Digit 3: Frequency [Hz]
o Digit 4: Voltage [V]
With this information, the example in the figure above reads as follows:
Voltage at generator between phase L2 and N is at 235.0 volts
Digit 1: Generator
Digit 2: Measurement between phase L2 and N
Digits 3 to 6: Numerical value 235.0
Indicator at digit 4: Voltage [V]

J1939 Visualization [320X], [350X]
J1939 Operating Value Display

The easYgen-300 with the X package is able to display standard J1939 messages, which are sent by the engine
control to the easYgen via the CAN bus. The values are displayed on the unit and in LeoPC1. In order to visual-
ize J1939 messages with LeoPC1, the PC/laptop running LeoPC1 must be connected via the DPC interface (refer
to page 31). It is also possible to display Scania S6 and Deutz EMR2 messages in LeoPC1. The J1939 visualiza-
tion can be configured with parameter 90, J1939 device type. If this parameter is not configured to Off, the stan-
dard J1939 messages are displayed on the unit immediately following the operating values as described in the
chapter Display of the Operating Values on page 36.
You find detailed information about the J1939 visualization with LeoPC1 under J1939 Protocol Descriptions
starting on page 104.
NOTE
Only signals, which are present, will be displayed. If a signal is not sent to the control unit, the display
of this value is not shown. If the sent values exceed the specified range, the displayed value is not de-
fined.
The following J1939 messages can be displayed by the easYgen. The J1939 messages follow the operating val-
ues and can be viewed in the following order using the Scroll button 1 . The values are updated by pressing
the scroll button.

Table 7-3: J 1939 messages
In case of a defective sensor or a broken wire the easYgen-300 displays four dashes instead of the J1939 value
following the respective J1939 identifier.
Figure 7-3: J1939 fault display
The above display shows that the engine oil pressure (identifier 9r) sensor is defective or the cable from the sen-
sor to the ECU is unplugged or broken. A defective sensor or a broken wire is also displayed in LeoPC1. The
display appearing in this case is described under J1939 Protocol Descriptions starting on page 104.

J1939 DM1/DM2 Error Message Display

The easYgen-300 with the X package is able to display J1939 DM1 and DM2 error messages, which are sent by
the engine control to the easYgen via the CAN bus. The J1939 visualization can be configured with parame-
ter 90, J1939 device type. If this parameter is not configured to Off, the J1939 DM1 and DM2 error messages are
displayed on the unit if the unit is in STOP operating mode.
If the easYgen receives an error message, this will be evaluated in the unit and the scrolling display starts if no
alarm is present. The scrolling display may be cleared by pressing the Alarm button 2 . If DM1 and DM2 er-
ror messages are present at the same time, the scrolling display of the DM1 error messages is displayed as long as
no alarm is present. If the scrolling display of the DM1 error messages is cleared by pressing the Alarm button
2 , the scrolling display of the DM2 error messages is displayed. If all scrolling displays are cleared, the op-
erating value display is active again. A scrolling display can only be cleared at least 10 seconds after the first oc-
currence. If DM1 error messages are not received anymore for at least 10 seconds they will be reset in LeoPC1.
The following content is visualized for DM1 and DM2 error messages:
• DM identifier DM1 (Data Memory 1) or DM2
• SPN number Suspect Parameter Number
• FMI number Failure Mode Identifier
• OC Occurrence Counter
The error messages are indicated by a scrolling display. The scrolling display starts with a header, displays the
single messages, and ends with an end marker. There are two separate scrolling displays for DM1 error messages
and DM2 error messages. A scrolling display is composed as follows:
Content Display Description

Display header Header J1939 The header indicates the start of a scrolling message
dnx The data memory identifier indicates whether it is a DM1 message (dn1) or a
DM Identifier
DM2 message (dn2)
First error mes- xxxx
Suspect Parameter Number The four-digit SPN describes the error message
sage
Failure Mode Identifier xx The two-digit FMI describes the error message in detail
Occurrence Counter xx The two-digit OC indicates the number of occurrences of this error message
… … … Possible further error messages may be between the first and last error message

DM Identifier
DM2 message (dn2)
Last error mes- xxxx
Suspect Parameter Number The four-digit SPN describes the error message
sage
Failure Mode Identifier xx The two-digit FMI describes the error message in detail
Occurrence Counter xx The two-digit OC indicates the number of occurrences of this error message
Display end End Marker End The end marker indicates the end of the scrolling message
Table 7-4: DM1/DM2 error message composition
The header is displayed left-justified in the 7-segement display for one second and then it starts to scroll. The
header and the first error message are separated by a blank. The four content elements of an error message are
separated by a dash. Individual error messages are separated by two blanks. The last error message and the end
marker are separated by two blanks. The end marker is displayed for one second. Then the scrolling display starts
again.
Example for a scrolling display with only one error message:

J1939 dn1-0120-20-03 End
Example for a scrolling display with four error messages:

J1939 dn1-0120-20-03 dn1-0190-05-09 dn1-1312-31-10 dn1-0091-06-04 End
NOTE
The J1939 DM1 or DM2 error messages are only displayed in STOP operating mode.
You find detailed information about the J1939 protocol under J1939 Protocol Descriptions starting on page 104.

Alarm Messages
If the easYgen detects a fault condition, LED 14 starts to flash. The alarm message is displayed in the seven-
segment display 18 with a blinking "A" for alarm, an alarm number, and the respective alarm segment, if appli-
cable. The alarm may be acknowledged by pressing the Alarm button 2 . The flashing LED and "A" will
change to a continuously illuminated state and the relay will be reset. If more alarm conditions are present, the
operator may advance through the different alarm messages using the Scroll button 1 . By pressing the
Alarm button 2 again, the alarm may be cleared unless the fault condition is still present.
Figure 7-4 shows the additional alarm states using the vertical segments of the last two digits of the seven-
segment display 18 . The four top segments are pre-assigned with the alarms shown in Figure 7-4, but are freely
configurable via LeoPC1 for common alarms from a list of alarms located in Table 7-6. The customer-defined
paper strip label allows for a customized front display panel. The lower four segments are permanently assigned
to engine alarms (battery undervoltage (alarm no. 50A), engine over/underspeed (no. 20A/21A), oil pressure (no.
60A), and coolant temperature (no. 61A)).

Operating Modes
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Operating Mode STOP
NOTE
Selecting the operating mode STOP is not the same as an EMERGENCY STOP. In some cases the
easYgen will perform additional logic functions, such as an engine cool down period, before the en-
gine is stopped. It is recommended that an EMERGENCY STOP discrete input is utilized and pro-
grammed as a class F alarm (only configurable via LeoPC1).
In the STOP operating mode neither the engine or the power circuit breakers can be operated. The
following occurs if operating mode STOP has been selected while…
…the engine is not running

1. The GCB will not close
2. The fuel solenoid relay cannot be enabled
3. The discrete inputs "Oil pressure" and "Coolant Temperature" are ignored
4. The push buttons START - STOP and BREAKER CONTROL are disabled
5. The engine/generator monitoring remains de-activated (exception: all monitoring that is not delayed by the
delayed engine speed monitoring)
6. The MCB will be closed if it is open [350], [350X]
…the engine is running

1. The GCB will open if it is closed
2. The MCB will close if the GCB is open and mains are present

In the AUTOMATIC operating mode, all engine, GCB, and/or MCB functions are operated via the
discrete inputs or automatically by the control unit (i.e. a mains failure). The function of the easY-
gen depends on the configuration of the unit and how the external signals are used. LED 15 , in the

AMF / Auto Mains Failure Operation - [350], [350X]
The operation sequence for an AMF operation is similar to the above sequence with the difference that a remote
start signal is not required for the engine start and the engine monitoring delay time is not considered, i.e. the
CBs are operated immediately. For an AMF operation in automatic mode the parameter Emergency power moni-
toring (page 74) must be configured to ON, no class F alarms may be present, the engine must be ready for op-
eration, and the configured mains fail delay time (page 74) must expire to start the engine.
Example for an AMF Operation:
Initial situation:
• Mains are present

• Mains circuit breaker is closed
• The generator controller is in the automatic operation mode and emergency stand-by
A mains failure occurs:
• Mains are not present
Reaction of the unit:
• The mains failure is detected by the unit

• The period configured in the parameter "Mains fail delay time" expires
• The period configured in the parameter "Preglow time" expires
• The generator will be started
• The mains circuit breaker will be opened
• The time configured in the parameter "Transfer time GCBMCB" expires
• The generator circuit breaker will be closed
• The unit is in auto emergency power operation now
The mains return:
• The return of the mains is detected by the unit

• The period configured in the parameter "Mains settling time" expires
• The generator circuit breaker will be opened
• The "Transfer time GCBMCB" and "Cool down time" timers start to run
• If the time configured in the parameter "Transfer time GCBMCB" expires, the MCB will be closed
• If the time configured in the parameter "Cool down time" expires, the generator/engine will be shut
down
• The unit is back in emergency stand-by

Breaker Closure Limits

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Generator Circuit Breaker
The easYgen-300 series has fixed breaker closure limits which prevent the GCB closure if the generator voltage
and/or frequency is/are not within these limits. These limits depend on the parameters rated system frequency and
rated generator voltage (refer to Measuring on page 70) and cannot be changed. The limits are set as follows:
fgenerator must be within frated system +/- 10 %

Examples:
If the rated system frequency is set to 50 Hz, the upper limit is at 55 Hz and the lower limit is at 45 Hz.
If the rated system frequency is set to 60 Hz, the upper limit is at 66 Hz and the lower limit is at 54 Hz.
Vgenerator must be within Vrated generator +/- 10 %

Examples:
If the rated generator voltage is set to 400 V, the upper limit is at 440 V and the lower limit is at 360 V.
If the rated generator voltage is set to 120 V, the upper limit is at 108 V and the lower limit is at 132 V.
If the generator voltage and/or frequency is/are not within these limits, the generator LED 12 is flashing and the
GCB cannot be closed.
If the generator voltage and frequency are within these limits, the generator LED 12 is permanently on and the
GCB may be closed.
Mains Circuit Breaker

The easYgen-350 and 350X have flexible breaker closure limits which prevent the MCB closure if the mains
voltage and/or frequency is/are not within the mains failure limits.
These limits depend on the parameters rated system frequency and rated mains voltage and can be freely config-
ured (refer to Monitoring: Mains Failure Limits on page 79 for details).
The conditions for closing the MCB are specified as follows and all conditions must be fulfilled:
• The mains voltage is present.

• The mains settling time (refer to Emergency Power (AMF) on page 74) has expired.
• NONE of the following alarms is present:
- Mains over/underfrequency
- Mains over/undervoltage
- Mains rotation field alarm
If the mains voltage is present, but the voltage and/or frequency is/are not within these limits, the mains LED 9
is flashing, and the MCB cannot be closed.
If the mains voltage and frequency are within these limits, and the mains settling time has expired, the mains
LED 9 is illuminated permanently, and the MCB may be closed.
The mains LED 9 is off, if the phase-neutral measuring voltage is below 10V.

Functional Description of the Oil Pressure Input DI1

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The easYgen-300 series is provided with an input for oil pressure. The function of this discrete input is described
in the following.
Vdc (GND) 15
Discrete input DI1 (oil pressure)
GND (Vdc) 16
Oil pressure switch
Figure 8-2: Discrete input DI1 - oil pressure

15 DI1 oil pressure common 2.5 mm²
16 DI1 oil pressure signal 2.5 mm²
Table 8-1: Discrete input DI1 - oil pressure
The oil pressure switch is connected to the terminals 15 (common) and 16 (DI1 signal) on the easYgen-300. The
oil pressure switch (OPS) must be a N.C. contact. If the oil pressure is below the minimum required pressure, the
contacts need to close. If the oil pressure is above the minimum required pressure, the contacts need to be open.
The oil pressure is only monitored if the easYgen detects speed/frequency from the genset. If the genset is in a
stand-by or stop mode, the oil pressure switch is disabled.
Parameter "Crank termination by DI1"
If the parameter "Crank termination by DI1" is enabled, the oil pressure can be used to terminate the starting sys-
tem for the engine. 2 seconds after oil pressure is detected, the crank relay will be disabled. The delay ensures
that the crank relay is not disabled prior to the engine reaching firing speed.
Parameter "Starter time"
In all other applications, the starter is active only for the time configured in the parameter "Starter time".
The following diagram shows the starting procedure as a function of time.
Figure 8-3: Starting procedure

Firing Speed Detection and Crank Termination

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The firing speed is used for crank termination if the parameter "Crank termination by DI1" is not enabled (refer
to Parameter "Crank termination by DI1" on page 60 if this parameter is enabled). When "Crank termination by
DI1" is disabled, the firing speed is determined by the generator frequency or is calculated from the nominal
speed and the rated system frequency. The control unit shows the following behavior:
Case 1:
Firing speed is reached if a minimum generator frequency of 15 Hz is detected. The easYgen versions [320] and
[350] operate in this manner. It is possible for the easYgen versions [320X] and [350X] to also operate in this
manner if the parameter "Speed pickup" is disabled.
Case 2:
Firing speed is reached if the calculated firing speed is detected via an MPU. The easYgen versions [320X] and
[350X] must have the parameter "Speed pickup" enabled to operate in this manner.
Nominal Speed
The firing speed is calculated according to the following formula: Firing Speed =
Rated System Frequency
* 15 Hz
Example: If the nominal speed is 1,500 rpm and the rated system frequency is 50 Hz, the firing speed will be
(1,500 rpm / 50Hz) * 15 Hz = 450 rpm. The crank will be terminated if the calculated speed exceeds 450 rpm.

Functional Description of the Charging Alternator Input/Output

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The easYgen-300 series monitors the charging alternator operation with the following functionality.
In some cases the alternator itself needs auxiliary excitation from an auxiliary DC source to build up its terminal
voltage during start-up. For this, the battery will be connected into the alternator excitation windings during the
engine start-up. This ensures that the alternator will be self-excitated and provides voltage for charging the bat-
tery after the start-up sequence.
The easYgen provides two features:

1. Auxiliary excitation for the alternator
2. Continuous monitoring of the alternator terminal voltage
If the engine is started, the easYgen's internal electronic switch is closed simultaneously with the crank relay out-
put, and the battery voltage is applied to the exciter winding D+ through the internal switch contacts by termi-
nal 3 (for 24V systems) or terminal 4 (for 12V systems). This pre-excites the charging alternator so that voltage
is generated. The internal switch will disconnect the alternator excitation winding from the battery after the en-
gine has started properly and the crank relay output has been de-energized to terminate the crank cycle. Now, the
engine is driving the charging alternator, which is charging the battery through the alternator terminals. Terminal
3 (for 24V systems or terminal 4 for 12V systems) now acts as the charging alternator input for monitoring the
charging voltage.
If the voltage on terminal 3 or 4 falls below a defined limit, the easYgen will initiate an "alternator charge fail-
ure" alarm.
The terminals 3 and 4 for alternator excitation act as individual resistors for 12 or 24Vdc alternators for current
limiting against short circuit conditions due to the low impedance of the excitation winding.

start-up only. During regular operation, it acts as an input for monitoring the charging voltage.

Functional Description of the 2nd CB Close Delay Time

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The easYgen-300 series provides Delayed close GCB and Delayed close MCB (only [350], [350X]) signals in
the list of configurable parameters (find more details about this under Relay Outputs on page 90) in order to meet
the requirements of some special circuit breaker types which require an Enable CB Close signal before the actual
CB close signal. The function of these signals is described in the following text.
If those CBs are utilized, they require two Close CB signals with a time delay in between from two different re-
lays. This can be achieved by selecting Delayed close GCB (MCB) from the list of configurable parameters for a
freely configurable relay (relay 3 or 4). The delay time can be configured with the parameter 2nd GCB (MCB)
Close Delay Time. If the user initiates the command Close GCB (MCB), the signal is immediately issued from
the fixed relay (relay2 for GCB or relay 1 for MCB) assigned to give the close command. After the configured
delay time has expired, the second Close GCB (MCB) signal is issued. The user configures the delay time for the
second close command at the relay output.
Example for the functionality:
Assumption: The close GCB signal is to be issued parallel on a second relay with a delay. Relay 4 shall be used
in this example for this. The parameter "Relay 4" has to be configured to "Delayed close GCB" from the list of
configurable parameters (refer to Relay Outputs on page 90). The delay time may be configured with the parame-
ter "2nd GCB close delay time"(refer to Application on page 71). A period of 2 seconds shall be configured for
this example.
If the user triggers the command "Close GCB" now, the following sequence will be performed:
The signal "Close GCB" energizes the relay firmly assigned to it (relay 2) immediately.
After the configured delay has expired, the signal "Close GCB" energizes the relay assigned by the user (relay 4
in this example) with the configured delay.
Signal: close CB
t Signal: close CB with delay
The delay "t" corresponds with the values of the parameters "2nd GCB close delay time" and "2nd MCB close
delay time".
If the respective circuit breaker is opened, both relays return to their initial state.
NOTE
This functionality can only be configured using LeoPC1.

Functional Description of the Engine Released Signal

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The easYgen-300 series provides the engine released signal in the list of configurable parameters (find more de-
tails about this under Relay Outputs on page 90). It is possible to use this signal for some special applications. Its
functionality is described in the following for an emergency power supply.
Emergency power supply systems often require that all external system components (i.e. governors, etc.) except
the genset control be disconnected from the battery power supply and that the battery is not loaded unnecessarily
during engine downtime. This means that the external components shall only be connected with battery power, if
the engine is operating.
To achieve this, a genset control signal is required, which connects the external components to the battery, as
soon as the engine is started. This can be accomplished using the engine released signal when configuring a relay
(relay 3 [350], [350X] or 4) to initiate this signal. The functionality is described in the following text with relay
4.

Figure 8-5: AMF application with engine released signal
The following functionality depends on the setting of the fuel relay (page 72):
Fuel relay configured as operating solenoid:

The easYgen detects the mains loss and initiates the engine start. Relay 4 (configured to engine released) and re-
lay 5 (fuel relay) are energized. The fuel relay provides the fuel supply to the engine. Relay 4 closes the contact
K1 and connects the battery power to the external components that they are ready for operation. This ensures that
these external components are not energized until they are needed.
Fuel relay configured as stop solenoid:

The easYgen detects the mains loss and initiates the engine start. Relay 4 (configured to engine released) is ener-
gized. Relay 4 closes the contact K1 and connects the battery power to the external components that are needed
for operation. This ensures that these external components are not energized if they are not used. If the engine is
stopped, relay 5 (fuel relay) will be energized, cutting off the fuel supply.
NOTE
It is not recommended to use the fuel relay signal for connecting the external equipment with the bat-
tery since this signal drops in amplitude with every possible start pause in contrast to the engine re-
leased signal.

possible starting with revision B of the DPC (first delivered July 2003). If you have an older model
please contact our sales department.
For configuration of the unit via PC program please proceed as follows:
• Install the LeoPC1 program on your notebook/PC according to the provided user manual 37146. Consider the
options that are given during the installation.
• Prior to the completion of the installation you will be prompted to select the language with which you want to
start the PC program. The language of LeoPC1 may be changed at any time. The selection of the language re-
fers only to language with which the menus and subprograms that LeoPC1 program works with. This setting
will not change the configured language of the control unit.
• After the installation of LeoPC1 has been completed it is necessary to reboot your notebook/PC.
• Establish a connection between your notebook/PC and the control unit via the DPC cable. Insert the RJ45
plug into the RJ45 port on the control unit (see DPC - Direct Configuration Cable on page 31 for details) and
the serial cable to the COM1 port of your notebook/PC.
• You can now start the PC program as follows:
- by "Start/Program/Woodward/LeoPC1" (version 3.1 or higher) and opening the respective cfg file, or
- by a double click on the respective file ending ".cfg" in the subdirectory "/LeoPC1".
The cfg files differ in their language used. Use the file on the enclosed floppy disk with the language you
want, i.e. US for US English or DE for German.
• After the LeoPC1 program has started, establish communication by pressing the F2 button or selecting Com-
munication -> Connect from the menu. This will establish a data link between the control unit and the note-
book/PC.
• Start the configuration routine pressing the F3 button or selecting Devices -> Parameterize from the menu and
adjust the parameter of the unit to your application using this manual.
NOTE
You find detailed information about LeoPC1 and the utilization of the software in the user manual
37146 belonging to it.
NOTE
The connection cables delivered with the DPC must be used to connect it to ensure a proper function
of the easYgen. An extension or utilization of different cable types for the connection between easYgen
and DPC may result in a malfunction of the easYgen. This may further result in damage to components
of the system. If an extension of the data connection line is required, only the serial cable between DPC
and notebook/PC may be extended.
NOTE
Unplug the DPC after configuration to ensure a safe operation! If the DPC remains plugged into the
easYgen-300 unit, a safe operation of the unit can not be guaranteed.

Editing the Configuration File

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
If you want to edit the configuration file in order to inhibit resetting the counters, you have to proceed as follows:
Open the configuration file in a text editor
In order to edit the configuration file, open the respective *.asm file in the "Tools" subdirectory of your LeoPC1
installation path with a text editor like Microsoft Notepad. An example of a name (depending on unit and soft-
ware version) for a configuration file is:
8440-1701_NEW_EASYGEN350X_x20002_pDirUS.asm
Delete the lines which are used to display the counter entries in the LeoPC1 configuration
The lines to be deleted in the *.asm file are:
;!K <b> <color=EE0000> --CONFIG.COUNTERS---</b>

%TAB 0,0,0,H'03;!z2550,"> Maintenance hours","0000h",1.0,0,9999
%TAB 0,0,0,H'03;!M2562,"> reset maintenance period h" ,H'FFFF,2,"No","Yes"
%TAB 0,0,0,H'03;!l2515,"> Counter value preset","00000000",1.0
%TAB 0,0,0,H'03;!M2554,"> Set operation hours" ,H'FFFF,2,"No","Yes"
%TAB 0,0,0,H'03;!z2540,"> Number of starts","00000",1.0,0,65535
Store the modified file
Store the modified configuration file back to the "Tools" subdirectory of your LeoPC1 installation path under the
same file name.
If you load the modified file in LeoPC1 now, the deleted lines will not be displayed in the configuration menu
anymore.
Configuring the Flags

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The easYgen-300 series provides four configurable LED flags in the alphanumerical display to indicate alarms.
One or more alarm messages can be assigned to each one of these flags (i.e. the respective flag will be illumi-
nated if the configured alarm state(s) occur(s) in addition to the regular alarm indication). A detailed description
of these flags can be found in the chapter Alarm Messages on page 40. The configuration parameter is described
in detail under Flags on page 95. The flags may only be configured using LeoPC1.
Configurable display flag 4

Figure 9-1: Configurable display flags

The flag parameters are displayed in LeoPC1 (refer to Configuration Using the PC on page 66 and the LeoPC1
user manual 37146 for more information) under System – Codes like shown in Figure 9-2 in default state (alarm
"Start fail" is assigned to flag 1). The parameter with the name "Flag 1 Start fail" has the value "Yes", i.e. the
alarm "Start fail" is assigned to flag 1.
Figure 9-2: Flag configuration default
You may assign as many alarms as required to one flag using LeoPC1. Just mark the respective entry and press
Input to configure the alarm assignment or double-click the entry for configuration. The example in Figure 9-3
shows that the alarms "Unintended stop" and "Start fail" are assigned to flag 1, i.e. the flag is illuminated (flash-
ing) if at least one of these alarms is present.

rupted for the mains settling time (see parameter on page 74). If the monitored

Discrete Inputs
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The easYgen-300 series has 5 discrete inputs (DI1 to DI5). The discrete inputs 1 & 2 are pre-defined as alarm in-
puts for oil pressure (DI1) and coolant temperature (DI2). The discrete input 3 is a control input for remote start.
The functions of the discrete inputs 4 and 5 are dependent on the parameter Ignore CB reply (see page 71). If this
parameter is set to NO, these discrete inputs are configured as reply inputs for MCB (DI4) and GCB (DI5). Any
changes made to the settings of the discrete inputs DI4 and DI5 have no effect. If this parameter is set to YES,
these inputs can be configured freely with the following parameters using LeoPC1.

Flags
The easYgen-300 series provides four configurable LED flags in the alphanumerical display to indicate alarms.
One or more alarm messages can be assigned to each one of these flags (i.e. the respective flag will be illumi-
nated if the configured alarm state(s) occur(s) in addition to the regular alarm indication). A detailed description
of these flags can be found in the chapter Alarm Messages on page 40 and a configuration example can be found
under Configuring the Flags on page 67.

Chapter 11.
Event Logger
The event logger is a FIFO (First In/First Out) memory for logging alarm events and operation states of the unit.
The capacity of the event logger is 15 entries. Additional event messages overwrite the oldest messages. Since
the easYgen-300 units do not include a clock module, the operating hours are stored with each event logger entry
as the timestamp.
The individual alarm messages, which are stored in the event history, are described in detail under Alarm Mes-
sages on page 40. The operation states, which are stored in the event history, are listed in Table 11-1 on page 98.
NOTE
The event logger cannot be read out directly from the front of the unit. It can only be read out using the
program GetEventLog, which can either be used as a stand alone or within LeoPC1.
GetEventLog Software
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Installing GetEventLog
GetEventLog can either be used as a stand alone or within LeoPC1. In order to call it up from LeoPC1, it must be
installed into the LeoPC1 installation path.
To install GetEventLog, start GetEventLog_vxxxxx.exe from the GetEventLog directory on the CD delivered
with the unit.
If you want to use GetEventLog from inside LeoPC1, it must be installed into the LeoPC1 installation directory.
Starting GetEventLog
Connect the easYgen to a free COM port on your computer using the DPC as described under Configuration Us-
ing the PC on page 66.
Start GetEventLog directly or call it up by selecting GetEventLog from the menu Tools in LeoPC1.
After starting GetEventLog for the first time, you must configure the communication settings. To do this, select
the Interface tab, configure the COM port according to the port, to which you have connected the DPC, and enter
the other settings as represented in figure Figure 11-1 since these are the default settings of the easYgen-300.
Figure 11-1: GetEventLog - interface configuration

Reading Out GetEventLog

On the Eventlog tab of GetEventLog, click the Request Eventlog button to read out the content of the event log-
ger memory. The content of the event logger is displayed as shown in Figure 11-2.
Figure 11-2: GetEventLog - event logger content
The 15 latest events are displayed in chronological order and each entry is composed like this:
"sign";"operating hour";"alarm/state"
whereas "sign""+" indicates the occurrence and "-" indicates the disappearance or acknowledgement of the
alarm or state
"operating hour" serves as a timestamp and indicates the operating hour of the event occurred
"alarm/state" indicates the type of alarm or change of state that occurred
The alarm codes are the same as displayed on the unit and described under Alarm Messages on page 40. The
codes for the operation states are indicated in Table 11-1 below.
Example: The entry "+";"00008.4h";"00031A" means that alarm 31A unintended stop "00031A" oc-
curred "+" at operating hour 8.4 "00008.4h". The operating hours are indicated in decimals, i.e. 8.4 hours are
8 hours and 24 minutes.

Storing Event Logger Data

Using the Save Eventlog button on the Eventlog tab, you are able to save the content of the event logger in
CSV format (comma separated values).
Resetting the Event Logger

The event logger can only be reset using LeoPC1. To do this, perform the following steps:
Connect the easYgen with your PC and start LeoPC1 as described in Configuration Using the PC on page 66.
Set the parameter Factory settings to YES.
Set the parameter Clear Even Log to YES.
The event logger should be cleared.

Front Customization
The easYgen-300 series is designed language-independent, but can be customized to your demands using paper
strips. The left paper strip is intended for customization and may contain more detailed information about the dis-
play.
The right paper strip is divided in three parts. The lowest part serves for labeling the unit indicators (refer to
Display of the Operating Values on page 35). You can customize the paper strip to reflect the unit of measure in
your preferred language. The middle section serves for labeling the four configurable alarm flags (refer to Alarm
Messages on page 40). You can customize the paper strip to reflect the alarm message assigned to the respective
flag in your preferred language. The upper field is intended for customization and may contain more detailed in-
formation about the display.

Templates for paper strips in different languages can be found in the "Paper Strips" directory on the CD deliv-
ered with the unit. The templates are in Microsoft Word format and can be customized to your demands. Please
note that the paper strip geometry must not be modified in the templates. Just edit the text in the paper strips,
print them out, cut out the paper strips where indicated, and insert them into the openings at the side of the unit.
