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.

Configuration Example
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Mains Parallel Operation (mains interchange (import/export) power control)
The following example describes the configuration of a typical mains parallel operation with import/export power
control at the interchange point and load-dependent start/stop.
Multiple generators are to be operated in parallel to the mains maintaining a stable power at the interchange
point. The generators shall be started depending on the momentary load at the plant. An emergency operation in
case of a mains failure is also intended. The load dependent start/stop function (LDSS) shall be enabled with a
remote start request and during emergency operation. LDSS shall depend on the reserve power on the busbar. In
case of a dead busbar (caused by a mains failure) all capable generators shall be started and operated with their
minimum running time. No generator priority is considered. Generator selection shall be performed depending on
the operating hours.
The following assumptions are valid for this example:
•3 generators, each with 80 kW rated power, are available.
•The recommended minimum load for the generators is 40 kW.
•The minimum running time is 180 s.

Configuring Load-Dependent Start/Stop Isolated Operation
Additional assumptions are valid for isolated operation (IOP), i.e. in case of an emergency operation:
•A reserve power of 80 kW on the busbar shall be maintained, i.e. at least 2 generators are available in iso-
lated operation for redundancy because no supporting mains are present.
•A hysteresis of 20 kW is required to avoid frequent starts and stops.
•The delay for adding another generator shall be 10 seconds.
•The delay for adding another generator shall be reduced to 3 seconds if a generator at the busbar is operating
above its rated load (accelerated start of the next generator).
•The delay for removing a generator from the busbar shall be 180 seconds.
From the main screen on the unit select Parameter -> Configuration -> Application config. -> Automatic run con-
fig. -> Load dependent start/stop -> Isolated operation and configure the following parameters:

Configuring Load-Dependent Start/Stop Mains Parallel Operation
Additional assumptions are valid for mains parallel operation (MOP):
•The first generator is only started if it is able to operate at a minimum load of 40 kW.
•A hysteresis of 20 kW is required to avoid frequent starts and stops.
•A reserve power of 10 kW on the busbar shall be maintained, i.e. at least 10 kW of generator capacity are
available for short load peaks. Higher load peaks are supported by the mains.
•The delay for adding another generator shall be 30 seconds.
•The delay for adding another generator shall be reduced to 10 seconds if a generator at the busbar is operat-
ing above its rated load (accelerated start of the next generator).
•The delay for removing a generator from the busbar shall be 60 seconds.

Special Application Examples
Generator Excitation Protection
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The easYgen-2000 Series provides the user with power factor monitoring. These monitoring functions permit for
protection of the generator over- and under-excitation. The power factor monitoring consists of a warning alarm
and/or a shutdown alarm when enabled. An alarm and the specified action will be initiated if the monitored pow-
er factor surpasses the defined limits. Typically the generator is monitored for loss of excitation and/or over exci-
tation in a mains parallel application. When a generator plant is paralleled against a utility, it is possible to control
the power factor at a desired reference. When the plant is operated in an island mode or isolated parallel applica-
tion, it is not possible to control the power factor. The load will dictate what the power factor is due to the reac-
tive nature of the load.
Figure 4-1 shows a typical power factor (generator excitation) protection range, where the desired range of opera-
tion (green area) is from 0.7 lagging (capacitive) to 0.8 leading (inductive). When the power factor exceeds either
of these limits by entering the yellow shaded areas starting at 0.7 lagging or 0.8 leading for more than 30 seconds,
a class B warning alarm is initiated. If the power factor exceeds the desired range further and enters the red
shaded areas starting at 0.5 lagging or 0.6 leading for 1 second, a class E alarm is initiated and the generator is
shut down.
Figure 4-1: Example - generator excitation protection
In order to achieve the described protection, the power factor monitoring parameters (refer to Configuration Ma-
nual 37427 for more information) have to be configured according to Table 4-1.

Configuring a Set Point Control via Analog Input
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The following example illustrates how to configure an easYgen for using an external load set point via analog in-
put [AI 03]. The external set point may be enabled using a switch, wired to discrete input [DI 04] (configure pa-
rameter 1262 “Alarm class” to control). An analog 0 to 20 mA input is to be used where 4 mA corresponds with
0 % power (0 MW), 12 mA corresponds with 50 % power (1 MW), and 20 mA corresponds with 100 % power
(2 MW).

Creating Self-Toggling (Pulsing) Relays Using LogicsManager
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Various functions are possible with the LogicsManager. This is a simple example of a relay output that toggles
from energized to de-energized in automatic mode with adjustable on and off time. This pulsing relay may be
combined with a flexible limit, which can be programmed with a function like low battery voltage to get a blink-
ing warning light.
Relay 2 is the discrete output (DO 2) and Flag 5 is used as an auxiliary flag. Relay 2 will be ON (energized) for 2
seconds and then OFF (de-energized) for 2 seconds as long as the easYgen is in automatic mode.
Figure 4-5: Example - configuring Flag 5 for a pulsing relay
In this example is the Delay ON time in the LogicsManager of Flag 5 indicates how long the pause is. The Delay
OFF time of Relay 2 is the pulse duration.
