Alarm Acknowledgment

General notes

The alarm acknowledge handling is valid for following alarm classes

•

• Shutdown

•

• Trip/Stop

•

• Trip

Mute Horn

Any new active alarm activates the horn and is made visible by the flashing Alarm LED.

After pressing the "Down/Decrease" button, the horn is deactivated and the Alarm LED

changes from flashing to constantly active and stays active as long as any alarm is

present. An additional active alarm reactivates the horn and the Alarm LED starts flashing

again.

Stop by alarm

The operation mode automatically changes to STOP if a stopping alarm is active

(»Shutdown« or »Trip/Stop«).

Acknowledge alarm

In case of alarm condition, pressing the STOP button will reset the alarm.

Operation Modes

General notes

The easYgen offers three operation modes:

•

• AUTO

•

• MANUAL (MAN)

•

• STOP

•

• ... and an internal (non) operating phase during the start of the device itself

The operation mode can be initiated – provided the current settings allow for this

function:

•

• directly by pressing the respective button on the front panel

•

• directly by click on the respective button on the ToolKit-SC remote screen

•

• via discrete inputs

•

• via interface

3.3.1

General notes

In operation mode AUTO, both genset and breaker are under easYgen control. The start

and stopping of the engine is managed automatically, along with opening/closing the

breaker.

•

• supply load by generator

•

• start the engine

•

• stop the engine

3.3.2

Operation Mode MANual

General notes

In operation mode MANual, both genset and breakers are independent of each other

under easYgen control.

The starting and stopping of the engine are managed using the same procedure as in

AUTO mode but without breaker control. Breakers can be opened and closed without

taking care of load or genset state!

3.3.3

Operation Mode STOP

General notes

In operation mode STOP, the breaker is open and the engine is not running.

3.4

3.4.1

START/STOP Operation

Start engine to supply load

The AUTO Start procedure is going through sub procedures with own timers

3.5

Pressing

can stop the running generator as described above.

Transition Procedures

3.5.1

Disconnect during cranking

There are three conditions under control to abort the starting of the engine:

•

• speed sensor

•

• generator frequency

•

• engine oil pressure

They can be used separately or in combinations.

We recommend selecting all three at the same time: engine oil pressure together with

speed sensor, and generator frequency. This allows for an immediate separation of the

starter motor from the engine. Additionally, crank disconnect can be checked exactly.

When set to speed sensor, ensure that the number of flywheel teeth is the same as

setting.
