Overview

Using DALI lighting without complicated DALI commissioning

The lighting control system uses ECGs with DALI interfaces, for

example, in order to be able to signal lamp failures.

Using the N 525E switch/dimming actuators, it is now possible

to use DALI devices in GAMMA

instabus

without any prior

knowledge of the DALI system and DALI commissioning.

The N 525E switch/dimming actuators switches and dims eight

mutually independent groups of fluorescent lamps with

dimmable ECG with DALI interface. Up to eight DALI ECGs

can be connected to each of the eight channels.

The solution:

The benefits:

• Real 0 to 100% luminosity control

• High operating safety due to selective disconnection in the

event of a fault

• Fault indications for light groups

• For individual room light control

Proceed as follows:

• Connect the N 525E switch/dimming actuator to the KNX

• Connect each group of DALI ECGs that are to be jointly

controlled, to an output of the

N 525E switch/dimming actuator

• Configure each channel as a conventional actuator in the ETS

and program the device

You require the following:

• N 525E switch/dimming actuators (5WG1 525-1EB01)

• Dimmable ECGs with DALI interface

• ETS3 (current version see http://www.knx.org)

Note:

DALI stands for Digital Adressable Lighting Interface. DALI is a digital

interface that is integrated in the controlgear of lamps and enables flexible

wiring and commissioning. As well as switching and dimming functions, they

are also able to detect and signal lighting failures.
