Why L1 lights up when L2 is at least in 1%?

[almost]

Lets say that the system has:
Lamp1, connected to Ballast1, connected to EVG-AP2 and it is controlled by Line1 of profilux &
Lamp2, connected to Ballast2, connected to the same EVG-AP2 (of Ballast1) and it is controlled by Line2 of profilux.

What I have notice is: Lamp1 will not light up (regardless the dimming %) unless Lamp2 is at least in 1% (through PLC).

How can I avoid it?

I want to light up Lamp1 when Lamp2 is in 0% (and vice versa).

Should I buy more EVGS and have one ballast in every EVG?
If so, should I connect one Line (from profilux) to every single EVG and leave the second Line of the EVG unconnected? Whould it work that way?

[almost]

I am asking because I read, that if lamp is dimming in 1% it consumes 20% of total Watts.

The only reason I can imagine is you possibly connected the power lines of the ballasts in a wrong way.

Check if you've connected mains power to X101 and the lamp ballasts to X102/X103 (like discribed in the manual)

[almost]

If main power was connected to X102 then X103 should have one ballast on it and the other should be in X101.

In that case, would it work like my system does? :

"L1 dimms if L2 is in at least 1% and L2 dimms if L1 is at least in 1%".


( I will check the connections but have to open the Matrix).

[almost]

Check the Matrix, connections are fine (still open if any new photos needed).
I change the N & P cables, nothing new happened.

So, why this happens?

L1 lights up just a little bit the lights (L1 from 1% till 100%, lights in about 1%) until L2 is at least in 1%, then it dimms normall (and vice verca for L2).

Am I the only one with this problem?

In order to programm the illumination, I have to put 1% in L2 when L1 is up and that makes it a little bit difficult to programm.

And the main problem, the Wattage that it is 20% of the total lamp Watts when dimming in 1%.

Ok, if both lamps show this behaviour, the reason is somewhat else... The first post won't make this clear.

If you set L1 to 0% your L2 is off - doesn't matter of the L2 setting (0..100%)
If you set L1 to 1% or more, the L2 now follows the L2 values
and
If you set L2 to 0% your L1 is off - doesn't matter of the L1 setting (0..100%)
If you set L2 to 1% or more, the L1 now follows the L1 values

In this case it seems the shut off signals and the illumination (1-10V) signals do not match (simply twisted). Try twisting both control lines for the EVG1 and EVG2 at X104.

[almost]

Both lamps show this behaviour:

If I set L1 to 0% my L2 is in 1-3% - doesn't matter of the L2 setting 1..100% (and 0 for 0%)
If I set L1 to 1% or more, the L2 now follows the L2 values
and
If I set L2 to 0% my L1 is in 1-3% - doesn't matter of the L1 setting 1..100% (and 0 for 0%)
If I set L2 to 1% or more, the L1 now follows the L1 values

EVG1 takes 2 ballasts (each one control 2x T5) and is controlled by L1 & L2 and EVG2 takes another 2 ballasts (each one control 2x T5) and is controlled by L5 & L6.
(In the first post I tryed to simplify the situation in order to make it more easy for understanding).

The same happens for L5 & L6 (in EVG2).

If you could make zoom in the above pictures, you could see that control lines to ballasts are o.k..

The EVGS are: EVG-AP2 PL-0058

[almost]

I would like some help here.

The fact that I have to dimm L2 in 1% so as to dimm the L1 leads me to dimm L2 in 20% (to stop flickering the tubes, burn in completed) and that leads me to have more Wattage and NOT the spectrum I want in the aquarium (different tubes in pairs).

Please, advice.

I still think this ia a wiring problem at the EVG-AP2. I can't see the (complete) wiring in the photos - even if I zoom in...

I think the best solution is to disconnect both EVG-channels on the EVG-AP2 an reconnect step for step.

1. disconnect both EVG-channels at X102, X103 and X104
2. make sure the power line is connected to X101
3. make sure the ProfiLux control lines at X105 are correctly connected
4. connect the power of first channel of the EVG to X102 and the control lines of the first channel of the EVG to pin 1&2 of X104
5. check if the EVG works well (set the second illumination channel to 0%, the illumination of the first channel should follow the settings and switch off, if vthe value reach 0%
6. connect the power of second channel of the EVG to X103 and the control lines of the first channel of the EVG to pin 3&4 of X104
7. check if the EVG works well (set the first illumination channel to 0%, the illumination of the second channel should follow the settings and switch off, if vthe value reach 0%

If you still have problems, you should ask an electrican to connect the EVGs.

O.K. Frank,
I will do that, but before re-opening the Matrix, I was thinking:

Could I measure the 1-10V signal comes from line L1 & L2 (and then L5 & L6)?
Maybe, signal from L1 doesn't change if signal from L2 isn't 1%.
Then I will measure the signal come from L3 & L4 (moonlight & sunlight) which is working great to see what I will found.
(It's easier to do this and maybe the problem is in Profilux).

I will come back.

[almost]

Signals from Profi are o.k.
Will re-open & double check.

"Why L1 lights up & is dimmable only when L2 is at least in 1%?"

and the answer:

"Because + & - of ballast 1 is in Pin 3 & Pin 4 on X104".


Frank, you were right. :rolleyes:

Re-open the Matrix and find out that + & - of ballast1 were in EVG on + & - of ballast2 (and of course, vice versa).

Now it is working great and I can play with light colours! :):)
