lighttubes unwillingly linked

[Locarno]

Hi,

I have started working with the Profilux plus II and I have a problem with the dimmable light tubes.
The tube on port 2 start working only when the tube connected on port 1 is working.
The dimming of these 2 tubes are connected using both there own LF-ABOX.
Is there a setting in witch these ports can be (wrongly) connected/linked ???
Or what did I do wrong !! the tube on port 3 is working correctly.

Regards,
Hans

Yes, this works.
Splitter connected to the L port, then the two LF-ABOX to the splitter.
You have to set the second LF-ABOX to the second channel.

The LF-ABOX have two jumpers. One jumper for the 1-10V control line and one jumper for the shut off control line. You have to set both jumpers to select an other channel.

Thanks for your fast reply,
I have looked fot jumpers on the LF-ABOX but dont see them. Do I have to open the LF-BOX ????? or are these softwarejumpers, and if so where can I reprogram these jumpers ?
In the manual is nothing about jumpers ! and what do you mean with "you have to set BOTH jumpers to select an other channel" set on or off or put them out ???

I have opened the LF-ABOX and now I see these jumpers !!! Very user unfriendly if I may say !
Now the question is how to handle these jumpers :
This is what I see : O = unused and X is connected with the other X.
So, do I have to connect the O with the X in the middle by swithing the jumper on both places?

O
X
X O X X

1-2 : L1/L3
2-3 : L2/L4

Are you sure the jumpers aren't mentioned in the manual? In my manual version (V200) the jumpers are described.

Ok, no matter:

Yes, you are right. Switch both jumpers to this places and the LF-ABOX is configured for channel 2.
There is a small 1 near the first jumper pins and this marks the first pin of the jumper.
Both jumpers at position 1-2: LF-ABOX is configured to channel 1
Both jumpers at position 2-3: LF-ABOX is configured to channel 2

X 1 O X X 1

1-2 : L1/L3
2-3 : L2/L4
