Problems dimming lower than 7%

[Gunther]

Maybe I should change the cable from the profilux to the drivers to a shielded one?!

This is not so easy due you need to have such a cable first.

For test purposes I would try it first:
- have a s much distance as possible between power cables and the signal cable
- use a tube or an old screen from a screened cable to protect signal cable temporarily. You should ground it on one side.
- don´t know where you located, but some countries have plugs you can turn by 180° - if yes, try this also (changing power and neutral wire)

You also should check if the ground of the drivers is available and o.k.

To my pwm card from stevesleds i use 2 channels and I need on ch1 (+) positive and (-) negative ; ch2 (+) positive and (-) negative

What is the correct connection from the profilux (pinout on the picture)

Is it ok to use the same (-) negative on both my channels? As I see it on the pinout there is only one negative from the profilux (pin 3)

I really want to solve this problem
Anyone have an idea?

Thanks for helping me!
Stevesleds says:

Quote:The wire connecting the controller to the ACI is picking up stray voltage/interference, or the wire is too thin gauge.

The driver won't blink unless it is over heating. End quote

One more think is when i unplug the rj12 from the profilux my ch1 is on about 8% and my ch2 is 0%

Thanks

Another quote from stevesleds

You may want to contact the manufacturer. I think Proflux can output PWM, which plugs directly into the driver with nothing else required.

Is that correct?

I think Proflux can output PWM,

Not directly but with the help of the PL-0776 LEDControl4Passive

Ok, thanks! That was also my thougt. I have this oneImageUploadedByTapatalk1359478709.676439.jpg
instead of the ghl PL-0776 LEDControl4Passive - maybe that is my problem?!

Now I bought the pl-0776
I'm gonna replace my stevesleds controller with that one and I really hope this is gonna work for me to dim down to 0% (it should work with the drivers)

Any thougts about that?

Björn please keep us posted. I believe that's the module you need to connect to StevesLED. Please take pictures of what you do and how you do it so others who use StevesLED can follow your lead.

Thank you in advance,

Hi Allen,

Hopefully I can do the installation tomorrow and I can also take some pictures and post here.

Now I tried to connect the profilux LEDControl4Passive to my drivers.

ImageUploadedByTapatalk1360057828.659266.jpg

The left RJ12 to profilux L1L2 port
LED-driver connector:
No1 to my drivers ground that is connected to my powersupply(dc-) stevesleds

No2 to Led driver channel 1 PWM input (stevesleds)
No3 to Led driver channel 2 PWM input (stevesleds)

When I turn everything on no lights at all! The profilux says it should be lights and I've tried different voltages and percents.
Connected the stevesleds controller back in again and the lights went on but not able to dim down to 0% as I want. Works pretty Well down to 7-8% then it starts to twinkle irregularly

Anyone have an idea??
