Why L2 dimms with L1 ?

[almost]

O.K.
The system:
Profi 3ex
Matrix 8 x 54W with 4 dimmable ballasts (2 lamps each) and 2 EVG-AP2.

1st EVG-AP2 controls the first (1P) & third Pairs (3P) of lamps, connected to L1 &L2
2nd EVG-AP2 controls the second (2P) & the forth Pairs (4P) of lamps connected to L5 & L6.

The problem: when I dimm L1 both 1P & 3P dimms together. When I dimm L2, nothing happens.

(When I dimm L5, the 2P dimms & when I dimm L6, the 4P dimms).

So, I changed lines goes to the EVGS and this is what happens:
When I dimm L5, the 1P dimms and when I dimm L6 the 3P dimms. But 2P & 4P dimms together when dimming L1 and nothing happens when I dimm L2.

Changed wires between lines, some thing.

So it is like L1 & L2 dimms together.

No problem with connection in the Matrix or the EVGS because I can dimm 1P & 3P (when connected to L5, L6) or 2P & 4P (when connected to L5,L6).

All boxs are ticked (dimmable etc), what should I do?

I had the same problem with my LEDs. Check your 1-10v interfaces in ProfiluxControl. For me, I had L1 set to identical Illumination channels.

Thanks mate, that was the case with me too.
