i
Flickering of the connected lamps is possible if the load is below the specified minimum.
This does not represent any defect in the device.
Behaviour after mains voltage failure in operation with DALI control unit
The behaviour is dependent on the DALI control unit.
i
The brightness of the lighting when DALI telegrams are missing – PowerON-Level – and in
case of DALI system voltage failure – SystemFailure-Level – is stored in the transformer
and can be changed using suitable DALI control units. In the state as supplied this is
maximum brightness.
Behaviour after mains voltage failure in operation with installation button
After mains return the switching position and the brightness that were stored before the mains
voltage failure are set.
4 Operation
Operation with DALI control unit
The operation and the behaviour of the transformer are dependent on the DALI control unit (see
instructions for the control unit).
Switching light with installation button
o
Press installation button briefly.
Light is switched on with the last brightness set or light is switched off.
i
If a fixed switch-on brightness was stored, the light is always switched on to this brightness
value.
Adjusting brightness with installation button
Light is switched on.
o
Make a long press on the installation button.
Light becomes brighter or dimmer as far as the respective limit value.
i
The dimming direction is reversed when there is another long press on the installation
button.
Switching light on to minimum brightness with installation button
o
Make a long press on the installation button until the light switches on.
i
If the installation button is still pressed, the light becomes brighter up to maximum
brightness.
Saving a fixed switch-on brightness
o
Set light to the required brightness.
o
Press installation button briefly twice in succession.
Fixed switch-on brightness has been saved permanently. For confirmation the light flashes
twice and switches to the saved brightness.
Deleting fixed switch-on brightness
Light is off.
o
Press installation button briefly twice in succession.
Fixed switch-on brightness has been deleted. For confirmation the light switches to
maximum brightness.
Synchronising transformers with installation button
In systems with more than one transformer it may be necessary to synchronise them, e.g.
because the brightness is no longer the same.
o
Make a long press on the installation button.
All transformers switch on.
o
Press installation button briefly.
