application. Password protection enables the assignment of multiple operation access

levels. Remote access, monitoring, visualization, and configuration are possible via

integrated interfaces. Communication between easYgens using PLC control or as a

network member offers an enhanced system management range; additionally supported

by easy to implement accessories.

The easYgen-600 are control units for engine-generator management applications.

The control units can be used in simple Start/Stop applications.

Scope of delivery

The following parts are included in the covering box. Please check prior to the installation

that all parts are present:

•Device easYgen genset control

•All screwable terminal connectors are delivered with plug and jack

•Clamp fastener installation material (4x)

A typical application mode for the control unit is the use for non parallel operation in a

single genset application.

• In this case, the easYgen will function as an engine control with generator and

engine protection.

• The control unit can open and close the circuit breaker .

Intended Use of This Control

easYgen-800 genset controllers are used for

• genset automation and monitor control system of single unit to achieve

• automatic start/stop,

• data measurement,

• alarm protection and

• three remote features: control, measuring and communication.

The controller adopts large liquid crystal display (LCD) and selectable Chinese, English or

other languages interface with easy and reliable operation.

This easYgen genset controllers adopt 32 bits micro-processor technology with precision

parameters measuring, fixed value adjustment, time setting and threshold adjusting and

etc. The majority of parameters can be set using front panel and all the parameters can

be set using PC (via USB port) and can be adjusted and monitored with the help of RS-485

port. It can be widely used in a number of automatic genset control system with compact

structure, simple connections and high reliability.

Functions

• Protection: automatic start/stop of the genset, ATS (Auto Transfer Switch) control

with failure indication and protection function

• All output ports are relay-out

• Parameter settings: parameters can be modified and stored in internal FLASH

memory and cannot be lost even in case of a power outage; most of them can be

adjusted using front panel of the controller and all of them can be modified using

ToolKit-SC on a PC via USB or RS485 ports.

• Temperature, oil pressure and fuel level curves can be used directly and users can

define the sensor curves by themselves.

• Multiple crank disconnect conditions (generator frequency, speed sensor, oil

pressure) are optional.

• Event log, real-time clock, scheduled start & stop generator (can be set as start

genset once a day/week/month with or without load).

• Start-up logo and display time are user-defined.

• Can be used on pumping units and as an indicating instrument (indicate and alarm

are enable only, relay is inhibited).

• Maintenance function: Actions (warning or shutdown) can be set when maintenance

time out.

• Instead of conventional analog modulation with a potentiometer, all parameters use

digital adjustment for more reliability and stability.

• Accumulative total run time and total electric energy of A and B. The user can reset

it to 0 and re-accumulate the value, which allows to count the total value.

• Precision measure and display parameters about Engine, Temp. (WT) °C/°F both be

displayed Oil pressure (OP) kPa/psi/bar all be displayed Fuel level (FL) %(unit) Speed

(SPD) r/min (unit) Battery Voltage (VB) V (unit) Charger Voltage (VD) V (unit) Hour

count (HC) can accumulate to max. 65535 hours. Start times can accumulate to

max. 65535 times

with perfect failure indication and protection function

• All output ports are relay-out

• Parameter setting: parameters can be modified and stored in internal FLASH

memory and cannot be lost even in case of power outage; most of them can be

adjusted using front panel of the controller and all of them can be modified using

ToolKit-SC configuration software on PC via USB, Ethernet, or RS485 ports

sensor

Key characteristics

• With ARM-based 32-bit SCM, highly integrated hardware, high reliability level

languages) which can be chosen at the site, making commissioning convenient for

factory personnel

• Improved LCD wear-resistance and scratch resistance due to hard screen acrylic

• Silicon panel and pushbuttons for better operation in high-temperature environment

• RS-485 communication port enabling remote control, remote measuring, remote

communication via ModBus protocol

• SMS (Short Message Service) function: When genset is alarming, controller can send

short messages via SMS automatically to max. 5 telephone numbers (external GSM

modem is needed). Besides this, generator status can be controlled and checked.

• Equipped with CAN bus port to communicate with J1939 genset. Monitoring

frequently-used data such as water temperature, oil pressure, speed, fuel

consumption and so on of ECU machine, and additionally also control start, stop,

raising speed, and speed droop via CAN bus port
