1.4 Safety
1.4.1 Intended Use
The easYgen unit has been designed and constructed solely for the intended use
described in this Operation Manual and – with even more details – in the Technical
Manual.
• Intended use requires operation of the control unit within the range outlined in the
written speci󰍓cations.
• Steps to be taken for commissioning are outlined in the Technical Manual.
• 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.
9easYgen-400B37890A
1 General Information
1.3 Service And Warranty

• 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.
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.
