If it was the programing the LED indicator would not go out it would stay on to indicate that the outlet still has power I dont know about every one else but on mine the LED goes out. am sure we will come up with a solution sooner or later

the led goes out on mine as well even though the lighting is still on. so it cant be a programming issue because the controller has sent a signal to the powerbar which opens the relay and turns off the led. when i do fix it, i can hear the relay close again. it has happened with metal halides and t5's. i've heard today that when other controllers first came out and released in north america there was similiar issues with the power bars. i'm assuming it has something to do with the conversion to 110v

let's summarize:
bullit67: the LED and socket work simultanesly, but they don't do what you expected. Maybe the wrong settings. If you can't solve this you can send me your configuration files (save Profilux's config with ProfiLuxControl), tell me what exactly you want to do and what the problem is. I'll have a look onto your settings and find the problem.
niloc16: LED and socket don't work simultanesly - we have an inrush current problem.
I had a discussion with an engineer of the manufacturer of the relays. He told me that the relays have the best available contact material for switching high currents. The limit is 120A for 20ms. If this is exceeded the contacts become to hot while switching, the contacts glue together. Because USA/CD only have 110V the currents are usually 2 times higher than in Europe, so an overload condition can be reached faster.
Devices with high inrush-currents are: Transformers, ballasts, switching power supplies, large electro motors. Good devices usuallay have an inrush-limiter included to protect switches or fuses of the power supply. But some of them do not - and they could cause this trouble.
Solution:
1. if possible use inrush current limiters (so called ILC) for your application when there are problems
2. I decided to ship the next generation of powerbars (the digital ones) with buil-in ICLs. Four channels will be protected (disadvantage of them: 8A permanent current), 2 channels will have full 15A and are not protected.
The powerbars have been redesigned, production starts today.
