6. 4. 3. 7 Warning Mode
The system switches to the Warning Mode if a problem occurs that impairs the sys-
tem’s normal operation. The Warning Mode is indicated by the red-green flashing
SYS-LED and is exited only once the problem is remedied.
The different warnings are binary coded and are indicated by the LEDs (F0...F4).

6. 4. 3. 8 Boot Mode
The boot mode enables an Emergency Upload via the Ethernet interface. This is re-
quired whenever there is no longer any executable system software stored on the
communication server for whatever reason or if a downgrade to an older software
version is to be carried out.
The Boot Mode is indicated by the SYS-LED flashing red.
To access the boot mode press the control key during the LED test red, which is ex-
ecuted during the start-up phase (see pattern[1], Tab. 89). The length of time the
pilot key is pressed is irrelevant. The red LEDs go off once the control key is pressed.
After a wait time of approx. 30 seconds, Pattern [21] of the boot mode is displayed.
Tab. 96 Combination patterns in Boot Mode
The boot mode remains active until the Emergency Upload is completed or the sys-
tem is restarted manually.
