I am getting ready to install 4 t5 set up that will be for dimming. I have 2 dimmable power bars and only one L port open L5/L6.
1. My question is can I put a splitter on the l5/l6 port and feed both dimmable power bars?
2. If I do this can the two bars be controlled differently? Lets say I want the first bar to dim first and then the second to start?
Thank you and I hope I didn't confuse everyone...

Yes, you can use a splitter.Quote:

Yes I have 2 dimmable power bars. 2 fixtures plug into 1 bar and the other 2 in the other power bar.Quote:

OK, so you want to control 2 ballasts.
If you're using 1-10V ballasts, you will need an EVG-AP-2F to control the shutting-off of your lights. With this item you will connect the ballasts to it, and then you will be able to control both ballasts separately
No I dont think I am making my self clear Im sorry.
I have 4 advance 24 watt dimmable ballast that I received from aqua digital. I also purchased 2 dimmable GHL power bars. I have the profilux ex controller with all the slots. The only slot I have open right now is the L5/L6 port on the back of the controller.
If i put a spliter on that port and connect the 2 power bars that have all 4 ballast connected to them will this be ok to dim the fixtures?
It is 1 ballast per 2 t5 so 4 ballast give me four plugs 2 per dimmable power bar.
Does this make sense?
thank you
Jimmy
BUMP need more info
Ok I can clear this confusion up ;)
Jimmy is using the PowerBar-2Dim AC variable power bar from GHL, so this has nothing to do with 1-10V ballasts Dali or EVG cards
Jimmy - The power bar 2 dim uses both channels on the 1-10V line so no you can not split it and put two powers bars on it otherwise the powerbars will act in pairs, unless this is what you wish to achieve?
Ok thanks Micheal,
I set up my T5 as illumination 3 and 4 so one socket reacts to 3 and one to 4.
If I split it with a y splitter 2 sockets react the same correct? If so it is fine I will make the first pair of lights on the right of the tank react the same and start dimming first and the second set on the left react to L4 starting 5 minutes later to create a sunset affect. what do you think??
Also does it matter how long it takes to dim to 100% and then back to 0% and do I need a burn in time?
Thank you very much,
Jimmy
Hi
Yes you are correct the ports will react together.
In regards to burn in times, this is something you would have to consult the lamp tube manufacturer for.
It can take as long as you like to go from 0-100%, the AC dimming has a different more compact curve than 1-10v diming so play with it to get the best results. You will have to adjust you input voltage also if you get flicker at low levels, it all depends on the tube you use, every one is different.
thank you Micheal,Quote:

thank you, Jimmy
Increase the voltage set in the 1-10V interface.
If no go set the off point to 10%, there is little viewable dimming curve below 15% generally
they are flickering after they pass 15%. What do you mean by increasing the voltage?Quote:

Also I am using version 4.05 does this matter should I update?
Thank you, jimmy
increase the min voltage, e.g. 3V
Hi, i have a little problem with the electronic ballast, my fixture have 2 electronics ballast, only on one, when they start, from 1% to 9% they work well, when they past then 10% the light shut off, and stay off, until a unplug the ballast, if i start the ballast a 20% and higher it work well.
the other one with exact the same setting and voltage, same tube, work well at all %
what ?????
i install your relay to shut off ballast.
Denis
ps, i try to exchange the tube from one ballast to the other and the probleme say to the same ballast.
exact ballast type?
