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
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.

Application Notes Starting Firmware V1.0016
Rated Voltage / Frequency Mains
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The proportional values for emergency mode relate to the generator nominal voltage. The mains has no own pa-
rameters yet (implemented in V1.0017).
Rated Voltage Generator
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The generator rated voltage relates to the secondary values of the generator voltage transformer. Since V1.0017 it
relates to the primary values!
Close GCB in MANUAL Mode
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The generator undervoltage monitoring level 1 and 2 must be enabled to close the GCB in MANUAL mode.
Emergency Mode
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
When the mains return after a mains failure and the DI release MCB is disabled, the GCB will stay closed as long
as the mains settling time is active. After that the GCB will open and the generator will shutdown. To prevent a
dead busbar the unit needs a signal for "Start req. in AUTO", see also Test With Load on page 18.

Preheating of Coolant Water
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
To set up a preheating of the coolant water the following is required:
1 temperature sensor, connected to T1 or T2, e.g. PT100
1 free limit of this analog input
1 free relay output for the heating (here relay2)
The temperature sensor is connected to the analog input (AI), here T1 (terminal 13/12). The first monitoring limit
of this AI is set to the selected temperature, e.g. 10°C with a delay time of 3s. The alarm class will be "control",
the monitoring is set to "Underrun", and self acknowledge to "YES".
The level 2 monitoring can be used for high temperature monitoring.

The relay 2 is energized as soon as level 1 is reached. It de-energizes when the temperature is 10°C+hysteresis
(Figure 3-1).

Emergency Mode with an External Mains Protection
(without Message Emergency Mode)
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
It is possible to close the GCB before the delayed engine monitoring is active like in emergency mode. If the de-
vice does not monitor the mains voltage itself it can get a signal from an external monitoring unit. Therefore you
need:
1 external mains protection unit, e.g. MFR11xx/MP or VDEW which has a signal connected to
1 free DI with alarm class "control" (here DI4)
The default value for the LogicsManager "Undelayed close GCB" is "4.9 Emergency mode". Enter the DI4 here
(Figure 3-2)
Figure 3-2
The parameter Flag 1 [1] is the default value, in this case there is no need to change it.
The DI4 must be in the conditions for "Start req. in auto" if the unit is supposed to run as soon as the external
mains protection is active (Figure 3-3). Enter an OFF-delay time (here 10s) also to keep the engine running dur-
ing a mains settling time or make sure that the signal is active for enough time, e.g. with a fall back delay time in
the MFR11.
Figure 3-3
The parameter Flag 1 [1] is the default value, in this case there is no need to change it.

Start in Auto Via Clock Daily/Weekly/Monthly
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The timer functions provide a wide range of possibilities how they could be used. Each of the settings can be
used and combined in the LogicsManager. They can be made longer or shorter depending on the OFF-delay and
ON-delay timers of the LogicsManager flags.
Setpoint 1/2 Is an adjustable time. If used in the LogicsManager it is active when this time of the day is
overrun. It is FALSE at midnight.
Application: Setpoint 1 and 2 can trigger a "Start req. in auto" daily between 8:00 (AM) and 17:00
(5:00PM). This is the default setting for flag 8 (Figure 3-4). For a start in automatic, the result
of flag 8 (00.08) must be entered as input condition in "Start req. in auto".
Figure 3-4
Active day Is the day of the month, e.g. 15 is every 15th of the month. It is TRUE for 24h as long as this
date is displayed from the internal clock.
Application: It could initiate an automatic start of the engine once a month (together with an active hour).
Active hour It is TRUE for 60 minutes, e.g. 15 means between 15:00:00 (3:00PM) and 15:59:59
(3:59:59PM).
Application Can be combined with other signals or e.g. open a louver/shutter every day for one hour.
Active minute It is TRUE the same minute every hour, e.g. the 5th minute for 60 seconds.
Application Can be combined with other signals or e.g. a lube pump runs for one minute every hour.
Active second TRUE every minute for one second.
Application Can be combined with other signals.
Monday active The internal calendar checks the actual weekday. The setpoint is active during the specified day
from 0:00:00 to 23:59:59.
Application See
Figure 3-4 above, default is set to run the engine every Monday till Friday but not on Sat-
urday and Sunday.
Tuesday to Sunday active: see Monday.

Special Functions for Discrete Inputs,
e.g. External Acknowledge and Firing Speed
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Firing Speed Reached (from V1.0100 with LogicsManager)
A discrete input can be used as a signal that the firing speed is reached e.g. from an electrical generator. Firing
speed reached means the starter is de-energized, the delayed engine monitoring timer starts and this DI will be
monitored with the "Speed/frequency mismatch" monitoring.
Example (high signal = firing speed reached), here for DI3:
Configure engine DI for firing speed = 3
Configure digital inputs DI3 operation = N.O.
DI3 delay = min 80ms, depending on application
Alarm class = Control
DI3 delayed by engine speed = No
DI3 self acknowledge = No
External Acknowledgement (from V1.0100 with LogicsManager)
This DI needs a high signal twice, the first to shut off the horn, the second to acknowledge all alarm messages. If
a momentary-contact switch is used please make a label saying it has to be pushed twice. The duration of pushing
depends on the setting of the DI delay time.
Examples of How To Define the Analog Input Tables
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
If a sensor type is used that has no selectable characteristic, the table A and B can be used. It is possible to
choose every point on the X-axis as well from the Y-axis.
The X-axis offers values between 0 and 100%, this is the minimum and maximum of the configured hardware
range. The device creates a straight line between the single points internally. It also creates a straight line be-
tween 0% and the first entered value and between the last entered value and 100%.
Here in this example:
last entered value X=50% Y= -2000 The unit displays always the value –2000 between 250 and 500 Ohms
(or 10-20mA)
The range for the Y-axis is –9999 to +9999. It has no dimension and no decimals. For values greater than –999
the parameter value format needs five zeros, the minus symbol needs one. For decimal values a decimal point is
required in the parameter value format, e.g. 000.0°F, see also Display the Analog Input Value in °F and psi on
page 19.
value format = 00000 (only via LeoPC1) All zeros in this parameter will be overwritten with the actual meas-
ured value
0%= 0Ohm and 100%= 500Ohm

Manual 37205D easYgen-1000 - Genset Control
Page 12/68 © Woodward
The X-values can be choosen in a way that the range with the highest curvature has the most points, see the (ex-
treme) example below:

Using an Analog Input Instead of a Discrete Input
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
It is possible to use an analog input instead of a digital input. We recommend a potential free contact. T1 is used
in this example (terminal 13-12).
Door open
Figure 3-7
Attention! The contact resistance has to be less than 500 Ohms. The maximum current is limited to 2,3 mA at
0 Ohms (see also technical data in the installations manual)
The analog input is set to 0-500 Ohms, linear scale. The default 0-1000 is ok. Enter the name in LeoPC1, like
"Door open". Only one limit is used, the other is switched off. Filter should be OFF, this is the shortest process-
ing time. The limit is set in the upper range (e.g. 800) to avoid problems if a contact resistance occurs.

The analog input displays now 1000 if the contact is open and 0 if it is closed. Depending on when the alarm
should come the monitoring is set to overrun or underrun and the requested alarm class and delay time is entered.
The shortest possible time until the GCB opens in case of a stopping alarm is 50 to 70ms. The time until a relay
energizes via the LogicsManager is about 110ms.

Critical Mode (Sprinkler Operation)
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
This LogicsManager flag is only active in automatic mode. There is no critical mode in manual mode, all alarms
keep their alarm classes.
General
All shutdown alarms become only warning alarms during critical mode. This mode is for a fire pump that is con-
nected to the genset (before the GCB).
Alarm classes
Class A remains A
Class B remains B
Class C becomes B
Class D becomes B
Class E becomes B
Class F becomes B
So a stop of the engine can only come from the settings in the LogicsManager, e.g. "Start fail" as a protection of
the starter and DI1 emergency stop. These are default settings and can be changed if necessary.
The number of start attempts is fixed to 10, in V1.0100 it is selectable
The engine provides a normal cooldown phase if the LogicsManager flag "critical mode" becomes FALSE. All
existing alarms get their original alarm classes and might stop the engine now!
Stop Engine During Critical Mode Manually
Switch to MANUAL mode: Press the start/stop button. All alarms return to their original alarm classes.
Switch to STOP mode: Press the STOP button once and the engine will stop with a cooldown. Press the STOP
button twice and it will stop the engine immediately without a cooldown. All alarms return to their original alarm
classes.
Critical Mode and Emergency Power Simultaneously {2oc}
The emergency power operation has priority. If a mains failure occurs during critical mode, the generator will
supply the busbar. Therefore the MCB will be opened and the GCB will be closed. A message "Emerg/Critical"
or "Notstrom/Sprinkler" (German) is displayed. All shutdown alarms become warning alarms.
Critical mode ends before mains recovery: The emergency power operation will be continued and all shutdown
alarms will become active again. If the mains return, the unit transfers the load after the mains settling time from
generator supply back to mains supply.
Emergency power operation ends before the end of the critical mode: The critical mode is maintained and after
the expiration of the mains settling time the load is transferred from generator supply to mains supply. The en-
gine remains running until the conditions for the critical mode become FALSE.

Critical Mode and Start Request
The critical mode operation has priority. If there is a critical mode request while the generator is running, the
GCB will open (in application mode {2oc} the mains will take over the load). A message "Critical mode" or
"Sprinklerbetrieb" (German) is displayed. All shutdown alarms become warning alarms.
Critical mode ends before the start request: The engine keeps running, in {2oc} there will be a change from
mains to generator supply. All shutdown alarms will become active again. After resetting the start request the
GCB will open and the engine will shutdown after a cooldown.
Start request is terminated before critical mode: The critical operation is continued. The engine keeps running un-
til the conditions for critical mode are FALSE. The engine will shutdown after a cooldown.
Configure Critical Mode
All default settings are suggestions. They can be changed depending on the requirements.
Two parameters have to be changed to activate a critical mode with the default settings:
Remove the "0" for flag 3 in "critical mode" (configure engine->start/stop -> critical mode V1.0017, or in con-
figure application->critical mode V1.0100). Then it should look like Figure 3-8.
Figure 3-8
2. Remove the "0" for DI5 in flag 3 (configure logic manager->Flag 3 V1.0017; configure logic manager-
>internal flags->Flag 3 V1.0100) change the alarm class for DI5 (or any other DI that is configured here) to con-
trol. Flag 3 has a default OFF-delay time of 600s, this means a postrun of 10min after the DI is "0" again. (Figure
3-9) Any other requested time could be entered here.
Figure 3-9
The parameter Flag 1 [1] is the default value, in this case there is no need to change it.

Stop of Critical Mode
The default settings interrupt a critical mode when an alarm start fail occurs (protection of the starter) or DI1 be-
comes active (see Figure 4-14). DI1 is preconfigured as "Emergency stop". If another input is used for this it has
to be entered here. A hard wired shutdown is also required. If nothing may stop the critical mode, a "1" has to be
entered on position 2 and 3.
If more shutdown inputs are required e.g. overfrequency (gen. Voltage) or overspeed (pickup) an additional free
available flag is required (here 4). Replace one of the stop conditions with flag 4 (Figure 3-10) and enter all re-
quired shutdown conditions in this flag 4 (Figure 3-11).
Figure 3-10
Figure 3-11
NOTE
Differences to other software versions: In {1oc} the GCB will always close if critical mode is active.

Load Shedding
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The device has internal load limits for the generator and the mains. A load shed via the generator power is set
like below:
Configure LogicsManager
Gen. load limit 1 or 2 = enter requested load limit, the value relates to the generator rated active
power, default 80/90%
Gen. load hysteresis = default is 5%, set depending on the load that is disconnected
The parameters 03.09 Gen load limit 1 and 03.10 Gen load limit 2 are used to energize a relay, here relay 1. An
ON-delay of 10s is set in this example. (Figure 3-12).
Figure 3-12
With this setting the relay 1 closes if the generator active load reaches limit 1 (80%) for 10s. This relay could
disconnect all load that is not needed urgently. It opens if the generator active load goes below 75% again. The
parameter Flag 1 [1] is the default value, in this case there is no need to change it.
Emergency Mode
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
When the mains return after a mains failure and the DI release MCB is switched OFF the GCB will stay closed
as long as the mains settling time is active. After that the GCB will open and the generator will shutdown. To
prevent a dead busbar the unit needs a signal for "start in AUTO".
Unable To Close GCB In 1-CB Mode
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The message in the display reads "GCB dead bus cls" but the relay is not energized. All voltages are in range,
there is no stopping alarm (class C, D, E or F).
-> The relay 8 terminal 40/41 (close MCB in a 2-CB application) has to be open in this time. As long as this relay
is energized, the GCB close relay will stay open!
Solution:
Use relay 8 only for functions that are not active at this time

Test Mode: How To Set Up a Test with or without Load
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
There are a lot of different opinions of the behavior of a proper test mode. The easYgen-1500 can support the
following two modes: Test with load and test without load. Both modes work only in automatic mode. The cor-
rect test mode depends on your local specifications.
Test With Load
This is the start in automatic mode in the block "Configure application". No special message appears on the dis-
play. If the mains fail during start in auto the unit keeps running until the mains return and the mains settling time
is expired or the conditions for "Start in auto" are FALSE again. It depends on which is longer active.
Test Without Load
A special logic manager flag was created in the block "Configure application" called "Start without load". If the
conditions for this logic manager flag are true the engine will provide an automatic starting sequence and keep
the generator running until this flag is FALSE again. Then the unit will perform an automatic stop sequence and
remain stand by in auto mode. No special message will occur during the test without load. If the mains fails dur-
ing test without load and the emergency mode is switched ON the unit will take over the load.
It will open the mains CB and close the Generator CB. When the mains comes back it will open the GCB after
the mains settling time and reclose the MCB. The engine will keep running until the conditions for Start without
load are false again.
Example for test without load: The engine shall start once a month and run for one hour without overtaking the
load. The test day shall be every fifteenth of a month (with flag 2, see also chapter Start in Auto Via Clock
Daily/Weekly/Monthly on page 10). A relay output can be configured that this test is running, e.g. for a signal
lamp (no figure).
Settings for the timer (Configure logic manager –> set timers)
Active day: 15
Active hour: e.g. 10
Flag for start via clock, here 2 (no default) (Figure 4-1)
Figure 4-1
Note: The default settings will cause a "start w / o load" (LM flag) if idle mode is active. This is to make sure
that the GCB won't close or will open as soon as idle is selected. This is only for automatic mode! If the breaker
is already closed in manual mode when idle is selected it will stay closed!
The parameter Flag 1 [1] is the default value and it is blocked by [1].

Display the Analog Input Value in °F and psi
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The freely programmable tables for the analog inputs are preconfigured for two VDO sensors. The table A is
used for pressure VDO 0 to 145psi (0 to 10bar), table B for temperature VDO 104 to 120°F (40 to 120°C). The
values in the table are with one digit after the comma, e.g. the value 512 in table A means 51.2 psi.
The following parameters have to be changed:
Analog input 1 or 2: Type: Table A or Table B
Select hardware: 0 to 500 Ohm
Offset: usually 0 Ohms except for contact resistance, then enter the value in
Ohms
Description: Name, e.g. oil pressure
Value format: 000.0psi or 000.0 °F in some versions of LeoPC1 the degree symbol
is not supported
Limits: table A: for 26.0psi enter 260
table B: for 190.0°F enter 1900,
