1.4 Safety
1.4.1 Intended Use
The easYgen unit has been designed and constructed solely for the intended use
described in this manual.
• Intended use requires operation of the control unit within the range outlined in the
speci󰍓cations listed in ╚═▷ “Technical Speci󰍓cations”.
• Steps to be taken for commissioning are outlined in ╚═▷ “Commissioning”.
• Intended use includes compliance with all instructions and safety notes presented in
this manual.
• Any use which exceeds or di󰍒ers from the intended use shall be considered improper
use.
• No claims for any kind for damage will be considered if such claims result from
improper use.
NOTICE!
Damage due to improper use!
Improper use of the remote panel unit may cause damage to the control unit as well as to
the connected components.
Improper use includes, but is not limited to:
•Operation outside the speci󰍓ed operating conditions.
1.4.2 Personnel
WARNING!
Hazards due to insu󰈢ciently quali󰈠ed personnel!
If unquali󰍓ed personnel perform work on or with the control unit hazards may arise which
can cause serious injury and substantial damage to property.
• Therefore, all work must only be carried out by appropriately quali󰍓ed personnel.
13easYgen-1600B37699A
1 General Information
1.4 Safety

This manual speci󰍓es the personnel quali󰍓cations required for the di󰍒erent areas of work,
listed below:
• Well trained for electrical installations.
• Aware of the local safety regulations.
• Experienced in working with electronic measuring and control devices.
• Allowed to manage the controlled (engine/generator) system.
The workforce must only consist of persons who can be expected to carry out their work
reliably. Persons with impaired reactions due to, for example, the consumption of drugs,
alcohol, or medication are prohibited.
When selecting personnel, the age-related and occupation-related regulations governing
the operating location must be observed.
1.4.3 General hazard warnings
Hazards by system controlled
DANGER!
Moving parts and dangerous electricity!
Be aware that the remote control of a system that is managing life-threatening engine-
generator-electricity parts must be adapted to the local situation!
The following safety notes cover both the device itself and basics of the overall genset
system. The dedicated genset-system safety instruction must be considered, too!
Prime mover safety
WARNING!
Hazards due to insu󰈢cient prime mover protection
The engine, turbine, or any other type of prime mover must be equipped with an
overspeed (over-temperature, or over-pressure, where applicable) shutdown device(s)
that operates independently of the prime mover control device(s) to protect from
runaway or damage to the engine, turbine, or any other type of prime mover. Failure to
comply with this also poses the risk of personal injury or loss of life if 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.

2 System Overview
General notes
The easYgen is a stand-alone genset controller with measuring, monitoring, and breaker
control functionality. It comes with an easily mountable plastic housing covering a
thoroughly tested electronic-electrical system.
Display and buttons of the HMI o󰍒er access to states and values, as well as access to the
application. Password protection enables the assignment of multiple operation access
levels. Remote access, monitoring, visualization, and con󰍓guration are possible via
integrated interfaces. Communication between easYgens using PLC control or as a
network member o󰍒ers an enhanced system management range; additionally supported
by easy to implement accessories.
For even higher challenges in genset control, the easYgen series o󰍒ers further solutions
encompassing complex and ambitious applications.
For dedicated protection tasks, ask Woodward for its protection (relay) solutions.
Operation Modes
•See ╚═▷ “Operation Modes”
2.1 Display and Status Indicators
General Notes
HMI and the con󰍓guration software enable access to control, settings, and visualization.
The front panel o󰍒ers a number of functionally de󰍓ned buttons and a set of menu
management buttons. LEDs visualize 󰍓xed states, the graphic display works together with
the menu management buttons to show all necessary information.
Restrictions
Full access to all parameters and settings with con󰍓guration software only!
HMI access o󰍒ers a number of information screens in general, and enables - password-
protected - access to parameters and settings.

2.2 Features and Functions of both easYgen-600 and -1600
Both easYgen-600 and easYgen-1600 are very close in hardware and software. The
easYgen-1600 is the device with more/higher functionality. For comparison and better
di󰍒erentiation both are described below.
easYgen-600 is intended to be used for single automation systems, auto start/stop of
the unit are performed with the help of remote signal.
easYgen-1600 has all functions of easYgen-600 as well as automatic mains failure
function (AMF), particularly well suited for single automation systems that include mains
and generator.
