- Brightness setting for luminaires with DALI interface

- Installation in appliance box to DIN 49073

- Observe the technical data.

Product characteristics

- If mains voltage is connected to the device "= active operation", it supplies the control

current for 26 DALI subscribers.

- If no mains voltage is connected "= passive operation", then the device is powered using

the DALI voltage and serves as an additional control section.

- Parallel switching of up to four "active" DALI potentiometers with the option of supplying up

to 104 DALI subscribers.

- All the control sections have the same functionality.

- Saving of a basic brightness and a fixed switch-on brightness.

Behaviour after a mains voltage failure

When the mains voltage returns, the lighting is switched to that switching state in which it was
located before the mains voltage failed. If the lighting was switched on, then the switch-on
brightness is set.
