The operation modes can be selected using four buttons. The LED above the corresponding button indicates 
the selected operation mode. The buttons can be electrically locked via an input (e.g. by connecting an 
external key-operated switch), to prevent unauthorised or accidental change of an operation mode. The 
operation modes described further down can be activated with these buttons.

PERATION MODE 

O

FF

 

 

The mode O

FF

 is automatically selected when battery voltage is applied (reset function), to prevent an 

accidental start-up. When the system is switched to O

FF

 from another operation mode: 

− 

The genset operation is terminated immediately, 

− 

Any alarms are deleted, except alarms 13 und 14 if their alarm contacts are still activated, 

− 

The control system is unlocked if no signal is present at the I

ANUAL

 

 

The auxiliary drives are switched on when the control unit has been switched to M

ANUAL

 mode. Pressing the 

START button, after the start is enabled by the auxiliary drivers, starts the engine. The generator CB can be 
switched on by pressing G

 (

) if the generator voltage is within its limits and no alarm that switches 

the generator off is present.  
Pressing the G

FF

 (

O

) button switches the generator CB off. The generator CB is operated only 

manually in this operation mode. 
Pressing the On-button has no effect if the voltage of the generator is not within the preset limits. A remote 
start command does not cause the generator to be switched on automatically. 
Select operation mode O

The genset is started after a remote start command when the start delay time is up. The auxiliary drives are 
switched on and the start sequence is begins when the start is enabled. The F

AIL TO 

S

TART

 alarm is triggered 

and the control unit is blocked if the genset has not started up at the end of the start sequence. The generator 
CB is switched on as soon as the genset has run up and the generator voltage and frequency are within their 
limits. 
A delay time follows (command-off delay) after the remote command is removed. After that, the generator 
CB is switched off. To prevent the engine from a heat increase, the generator set will run unloaded for the 
configured cooling down period, and then it will be shutdown.

In this operation mode the genset can be activated by two external start commands: 

− 

Start with generator operation, 

− 

Start without generator operation for an easy stand-by.
