Exlux luminaires with Dali interface

R. Stahl puts its out­stand­ing light­ing tech­nol­o­gy exper­tise to good use, sup­port­ing plant oper­a­tors dur­ing the plan­ning, instal­la­tion, pro­gram­ming and com­mis­sion­ing of dig­i­tal­ly net­worked light­ing sys­tems in haz­ardous areas. Now, the explo­sion pro­tec­tion expert has expand­ed its range, adding mod­ern explo­sion-pro­tect­ed light­ing sys­tems with Dali inter­faces. The new Exlux vari­ants cor­re­spond to the Dali stan­dard accord­ing to IEC 62386 and are specif­i­cal­ly designed for con­sis­tent light­ing man­age­ment for gen­er­al and emer­gency light­ing, even up to Zone 1 explo­sion pro­tec­tion. As well as safe­ty and emer­gency light­ing, the range includes par­tic­u­lar­ly durable, ener­gy effi­cient lin­ear lumi­naires that can be installed as ceil­ing, pen­dant or pole mount­ed light fittings.

These lumi­naires, from the Exlux 6002/4, 6402/4, 6009/4 and 6409/4 ranges, are designed to func­tion for over 100,000 oper­at­ing hours at a max­i­mum ambi­ent tem­per­a­ture of +60 °C and achieve excel­lent light out­put val­ues up to 145 lm/W. Thanks to the use of bidi­rec­tion­al Dali com­mu­ni­ca­tion, around 200 pro­gram­ma­ble com­mands can be con­fig­ured, allow­ing oper­a­tors to set dif­fer­ent inten­si­ty val­ues and dim­ming behav­iour for indi­vid­ual light fit­tings or lumi­naire groups. In addi­tion, sta­tus and func­tion­al data can be trans­mit­ted to the bus mas­ter. The Dali stan­dard makes it eas­i­er to inte­grate exter­nal sen­sors for pres­ence or day­light con­trol and offers addi­tion­al func­tions for con­tin­u­ous data stor­age (NVM), device iden­ti­fi­ca­tion, light val­ue detec­tion and error diag­no­sis. The auto­mat­ic retrieval of switch­ing states, error mes­sages and bright­ness val­ues sup­ports for­ward-look­ing main­te­nance con­cepts. For loca­tion-inde­pen­dent remote mon­i­tor­ing, data can be man­aged using a web brows­er or smart­phone app. The safe­ty and emer­gency light­ing mon­i­tor­ing func­tion encom­pass­es both the light fit­tings and the bat­tery sta­tus. This means that the Dali func­tion is auto­mat­i­cal­ly switched off in a sit­u­a­tion requir­ing emer­gency light­ing. R. Stahl sup­plies its Dali light fit­ting vari­ants as devices suit­able for hard-wired net­work­ing using the Dali 24 V DC bus. Ex d pro­tect­ed emp­ty enclo­sures are avail­able for installing a Dali mas­ter in a haz­ardous area.
