﻿The behaviour of the forced position after a bus or mains voltage return can be specified by this parameter. This initialises the forced position after a device reset.

After bus or mains voltage return, the configured state is transferred to the "Forced position - Activate/Deactivate" communication object. When a forced position is activated, the group or the single device is immediately activated and interlocked accordingly by forced control after bus/mains voltage return until a forced control takes place via the KNX. In this case, the parameter "After bus voltage return" is not evaluated.

*State before bus/mains voltage failure*: The last existing and internally stored state of the forced position before bus or mains voltage failure will be tracked. An ETS programming operation deletes the stored state (reaction in that case same as with "no forced position active"). If the tracked state corresponds to "No forced position active", the force-independent parameter "After bus voltage return" will be executed on return of bus voltage. If forced position is activated, the DALI operating devices are switched on to the brightness value predefined by the parameter "Forced position 'active, switch-on'".
