4.1 Power ON
Behavior during starting KEA 3X0
The start-up procedure of the KEA 3X0 device can be caused by the following reasons:
Power ON
Power cycling e.g. by 1701 p. 181 “ Set factory default values”
Power is back after voltage drop
This process is visualized by the HMI of the plastic housing version or the LEDs of the metal housing version.
Using the USB Service Port
With power ON and a PC/laptop connected via USB service port it can
happen that the USB window that pops up doesn't show all files and/or the
correct available free memory at the device: Please unplug/plug the USB
connection after the KEA finished starting.
With power ON and connected USB service port it can happen that a
connected USB device is not detected correctly: Please unplug/plug the USB
connection after the KEA finished starting.
With power cycle of the KEA 3X0 the USB connection is lost: Please
unplug/plug and/or start USB connection again after the KEA finished
starting.

4.2 Change Operating Modes
Startup
The genset controls starts in the operating mode defined by parameter 1795 [Startup in mode]. Refer to
Chapter 4.4.5. “Configure Operation Modes” on page 338 for details.
Select Operation Mode
Operation modes can be selected via
front panel buttons (plastic housing variant or Remote Panel RP 300 or VNC client),
HMI configuration (plastic housing variant or Remote Panel RP 300 or VNC client),
remote settings via interfaces, or
ToolKit
The following chapters describe the manually front panel access.
4.2.1 Operating Mode STOP
Usage
Use the STOP button to activate operating mode STOP.
Observe the notes on the system's reaction upon activation of operating mode
STOP as listed below.
STOP LED is illuminated at the front panel; ToolKit home page shows STOP icon left beside the prime mover.
System reaction
In operating mode STOP neither the engine nor the GCB can be operated. Dependent on the application mode
the power circuit breakers cannot be operated.

CAUTION!
Hazards due to improper use of operating mode STOP
Selecting the operating mode STOP is not the same as an EMERGENCY STOP.
In some cases the KEA will perform additional logic functions, such as an
engine cool down period, before the engine is stopped.
-For emergency stop functionality use an EMERGENCY STOP discrete
input, programmed as an F class alarm.
If the operating mode STOP is selected while the engine was already stopped the following applies:
The GCB will not be closed.
The fuel solenoid relay will not be enabled.
The start request is ignored.
The start push buttons (softkeys) are disabled.
The engine/generator monitoring remains activated (exception: all monitoring that is delayed by the
engine speed).
If the operating mode STOP is selected while the engine was running the following applies:
Dependent on the current application mode a soft shut down will be executed.
Pressing the STOP button again opens the GCB.
If the STOP button is pressed again, the cool down will be interrupted.
If the operating mode STOP is selected while the engine performs a cool down the following applies:
Pressing the STOP button again causes an immediate stop of the cool down and stops the engine.
If the conditions of the LogicsManager function "Enable MCB" (parameter
12923 p. 263/ p. 1038) are TRUE, the MCB will be closed again if it is open in
STOP operating mode.

4.2.2 Operating Mode MANUAL
General usage
In the MANUAL operating mode (mode button “MAN” illuminated) both the engine circuit breaker and the
power circuit breaker can be operated via the push buttons along the bottom of the display (softkeys).
Additionally the Start(I)/Stop(O) buttons can be used to start or stop the engine.
1 Mode button: MAN
2 START button: Engine
3 STOP button: Engine
4…6 Soft buttons: Breaker OPEN/CLOSE
Fig. 10: KEA 3X0 MAN-buttons
Use the mode button “MAN” to activate operating mode MANUAL.
The MAN button is illuminated.
The breakers will open immediately without power reduction. To open the
breaker in a no-load condition, reduce the load manually in the setpoints
screen (Chapter 4.1.5 “Specialized Menu Screens” on page 121).
Example for application mode A01
To start the engine:
Press the button [I] below the MAN button.
Success: The engine starts and the circular arrow and the eye symbol appear.
Failure: No change in the display until the "start failure" message appears.
To stop the engine:
Press the button [0] right below the MAN button.
Success: The engine stops and the circular arrow and the eye symbol disappear.
Failure: No change in the display until the "stop failure" message appears.
