Using DALI luminaires with easy KNX commissioning
Using DALI lighting without complicated DALI commissioning
Ballasts with a DALI interface are used in lighting controls, e.g. to
report lamp failure. The N 525E switch/dimmer actuator now makes
it possible to completely replace DALI devices with GAMMA instabus
without any knowledge of DALI or DALI commissioning procedures.
The N 525E switch/dimmer actuator switches and dims eight inde-
pendent groups of fluorescent lamps with dimmable ballasts and DALI
interfaces. Up to eight DALI ballasts can be connected to each of the
eight channels.
Benefits
• True 0 to 100% light value control
• High operating safety due to targeted shutdown in the event of an
error
• Error messages for luminaire groups
• For individual room lighting control
Follow these steps
• Connect the switch/dimmer actuator N 525E to the KNX
• Connect each group of DALI ballasts to be controlled jointly to one
output of the switch/dimmer actuator N 525E
• Configure each channel in ETS just as you would a conventional
actuator and program the device
You will need
• Switch/dimmer actuator N 525E
• Dimmable ballasts with DALI interfaces
• ETS; see knx.org for the latest version
Note:
DALI stands for Digital Addressable Lighting Interface. DALI is a digital
interface that is integrated in the controlgear of lights and enables
flexible wiring and commissioning. As well as switching and dimming
functions, they are also able to detect and signal lighting failures.
