These seings are achieved by soring he curren oupu values hrough a long press on he relevan buons nex o he oupu on he fron of he device. 2.1.3 Physical addressing In order o perform he physical addressing or o check wheher or no he bus is conneced, press he lighed push buon (see chaper 2.1.2 for he buon locaion). Ligh on = bus conneced and ready for physical addressing. Programming mode is acivaed, unil he physical address is ransferred from ETS. Pressing he buon again, exis programming mode. Physical addressing can be carried ou in auomaic or manual mode. TXA661 A/B - TXA663A - TXA664A 6 6LE001737A

2.2 Funcion modules of he applicaion The produc has several command modes, each wih a differen prioriy.. Prioriy P R I O R I T Y High Low Prioriy level 1 OUTPUT MODULE Oupu Dimming Basic funcions* P R I O R I T Y High Low Prioriy level 2 * ON/OFF - Dimming - Timer - Scene: The las command received will have prioriy. 2.2.1 Primary funcions The applicaions allow individual configuraion of he device oupus. The mos imporan funcions are: ON/OFF An oupu can be swiched on or off using he ON/OFF funcion. The command can come from swiches, buons or oher conrol inpus. TXA661 A/B - TXA663A - TXA664A 7 6LE001737A

Relaive or absolue dimming (Brighness value) Wih relaive dimming, he brighness value is raised or lowered wih respec o he curren brighness value. This is achieved, for example, by a long press on a sensor buon. Wih absolue dimming, he brighness value o be achieved is se on he dimmer as a % value. Timer The Timer funcion can swich a lighing circui on or off for a configurable period. The oupu can be swiched o a desired brighness level for a specified period. The imer may be inerruped before expiry of he delay ime. A programmable Cu-OFF pre-warning announces he end of he delay ime by halving he presen brighness value of he oupu. Prioriy The Prioriy funcion is used o force he oupu ino a defined sae. The Prioriy funcion is conrolled wih a 2-bi command. Prioriy: Prioriy > Basic funcion. Only a Prioriy OFF command auhorizes he oupu for conrol. Applicaion: Keeping lighing on for securiy reasons. Auomaic conrol The Auomaion funcionaliy allows commanding an oupu a he same ime as he ON/OFF funcionaliy or lighing value. The wo funcions have he same level of prioriy. The las command received will ac on he saus of he oupu. An addiional command objec is used o acivae or deacivae he Auomaic conrol. Scene The Scene funcion is used o swich groups of oupus ino a configurable predefined sae. A scene is acivaed by receip of a 1-bye command. Each oupu can be included in 64 differen scenes. Number of used oupus selecion (Reference TXA663A only) 1, 2 or 3 lighing circuis can be conrolled using his device. The maximum available power per oupu depends on he number of oupus used. The oal power oupu is limied o 900W: 1 oupu uses: 900W. 2 oupus use: One 600W oupu and one 300W oupu. 3 oupus use: 300W per oupu. Manual mode Manual mode allows he device o be disconneced from he bus. In his mode, each oupu can be prioriy conrolled locally.
