Safe-state mode
If the device - for instance as a result of errors in the project design or during commissioning - does not
work properly, the execution of the loaded application program can be paused by activating the safe-
state mode. In the safe-state mode, the outputs cannot be controlled via the bus. A manual control for
broadcast is the only feature that can be activated. The Gateway remains passive in safe-state mode
since the application program is not being executed (state-of-execution: terminated). Only the system
software is still functional so that the ETS diagnosis functions and also the programming of the device
continue to be possible.
Activating safe-state mode
Disconnect the mains voltage supply.
Press the programming key and keep it pressed.
Switch on the mains voltage supply. Release the programming key only after the programming LED
starts blinking slowly.
The safe-state mode is now activated. With another brief press on the programming key, the
programming mode can be switched on and off as usual also in the safe-state mode. The
programming LED will nonetheless continue to blink independent of the programming mode as long
as the safe-state mode remains active.
The safe-state mode can be terminated by switching off the mains voltage supply or by programming
with the ETS.
For the activation of the safe-state mode, the bus voltage does not have to be switched on.
Unloading the application program
The application program can be unloaded via the ETS. In this case, only manual control is possible for
the broadcast of connected DALI devices.
