ZPE 2771864 000 00 EN Page 1 of 11 DALI PROFESSIONAL Frequently Asked Questions What is the max. cable length in OSRAM DALI PROFESSIONAL system? Is it 300 m in total for all 4 DALI lines or 300 m per each DALI line? DALI lines are released for 300 m with 1.5 mm2 standard copper installation wires. The DALI PROFESSIONAL controller CONT-4 provides 4 electrical independent DALI lines which can be wired in opposite directions with the CONT-4 in the center. What is the wiring concept for DALI projects? DALI line topology is linear or star up to 300 m max. distance at min. 1.5 mm2 copper wire. But no closed loops, no ring topology. Do not mix with TOUCH DIM applications. Avoid shortcuts. DALI wiring needs only basic insulation to mains voltage, so standard installation cable NYM 5x1,5 mm2 is recommended. How many DALI ECGs can be used? In DALI there are 64 DALI ECG addresses per DALI line which results in 128 mA DALI current consumed by these ECGs. Because we have 4 DALI lines in DP CONT-4, there can be used max. 256 ECGs. For ECG with more addresses per unit (e.g. OSRAM OTi DALI 75 with optional 4 addresses) the max. number is reduced accordingly. How many DALI ECGs can be controlled individually in OSRAM DALI PROFESSIONAL? DALI PROFESSIONAL provides in total 256 DALI ECG addresses divided into 4 DALI lines. To control these individually you need 256 buttons or 64 pushbutton couplers which exceeds the maximum DALI current. With this you can only control 220 ECGs individually. To...
