Set the parameter to "Start Staircase timer function".
Independent of the “Switching” object, the Staircase timer function will be activated after bus voltage
return. Make sure that the Staircase timer function has been enabled in the parameterization of the
plug-in. In case the Staircase timer function has not been enabled, this setting will produce no
reaction after the return of bus/ mains voltage.
• Setting: “Brightness value as prior to bus voltage failure” When programming the application or the
parameter with the ETS, the internally stored switching state will be reset to “Off – 0".
• Forced-control position as an additional function: The communication object of the forced-control
position function can be separately initialized after bus voltage return. This will influence the reaction
of the group if the forced-control position in case of bus voltage return has been activated. The
parameterized “Response to bus voltage return” will be executed only if no forced-control position is
activated after a bus voltage return.
• Disable function as an additional function: Active disable functions will always be inactive after a bus
or mains voltage failure.
• Any switching state set after a bus/ mains voltage return will be tracked in the feedback objects.
• When the mains voltage returns at the connected DALI devices (e.g. supply via another mains phase
conductor) the devices will adjust to the brightness according to their "PowerOnLevel". This value will
be programmed into the devices during the commissioning of the DALI Gateway and corresponds to
the “Response to bus voltage return”.
When set to “No change”, “Switch off”, “Brightness value as prior to bus voltage failure” and “Start
Staircase timer function”, the value for minimum brightness will be programmed as “PowerOnLevel”
into the devices.
• When set to “No change”: the communication objects of the Gateway will be initialized with “0” after
bus/ mains voltage return. In this case, the returned switching status or brightness value feedback
corresponds to the 'true' brightness status of the group only if the group has been activated at least
once via the bus or manual control. No telegram will be transmitted if feedback objects are set to
actively transmitting.
• As soon as bus voltage returns the active manual control will be terminated. Manual control is
unavailable during a mains voltage failure.
• The DALI Gateway initializes after mains voltage return. During the initialization, " " will be
displayed on the front panel in the 7-segment display.
