ATI Powermodule 4 of 8 bulbs not working

[Pisanoal]

Hello everyone,

I bought a used gen 1 ati powermodule hybrid 8x80w. The 4 inner bulbs are all not firing.

All leds are working.

So far, I've moved bulbs around and confirmed it's not a bulb issue, also I swapped one of the ballasts I knew was working with one on a pair that was not working. Same result. Outer pairs fire, inner ones don't.

Previous owner said he thinks they all went out at the same time.

Not really sure where to go from here.

Any ideas?

@ATI North America

Thanks!

Could be ballast.

I have the early Power module before they were led and two bulbs are out and guessing it is a ballast too..

So if I understand what you did, the same pairs of bulbs continued to not work on both ballast? If so it sounds like a socket or broken wire or the sockets themselves. Otherwise I would have said the ballasts also.

Thanks for the replies.

Some clarification.

Outer pairs work, inner pairs do not.

I swapped one of the inner ballasts with one of the outer ballasts and the above statement did not change. So I'm confident it's not a ballast issue unless one bad ballast can cause both pairs (4 bulbs) not to fire which I don't think would happen based on how they are wired.

It seems unlikely that it would be a socket issue since they went out at the same time.

It seems likely that it is something that is common to both.

oops sorry missed the fact you swapped ballast already.

 

[Biglew11]

Do you have a multimeter? Check for voltage going to the ballasts.

 

[Pisanoal]

I do. I'll check tomorrow if I get a chance.

I spoke with ATI this morning and it sounds like based on what I have already tried, its likely to be a faulty relay on the control board. Unfortunately this means a full controller replacement which is ~$400. Its pretty frustrating that they don't have a replacement board option, as there is a lot of cost in the controller itself that has nothing to do with the board that's bad.

The other option is to find the relay and change it out on the board.

Any electronics gurus out there have the knowledge to help identify the relay and source a replacement?

look for the numbers on the relay. you may find one available with a google search.
look at digikey.com, newark.com (newark electronics) may be able to cross reference the part number.

 

[Pisanoal]

Confirmed bad relay. Only problem is I can only find the exact relay out of China. I can't seem to find one without a delivery date of a month or more.

Not sure how I would go about finding an equivalent.

 

[Biglew11]

Here's one from the us on ebay.

[Pisanoal]

Thanks. I saw that one too right after i posted. Difference of searching through google, and actually searching ebay.

I found this OJ-SS-112HM.000 one on digikey. I think its an equivalent but I'm not experienced in looking at this sort of thing. Specs seem the same as far as coil voltage/current, output voltage rating, pin layout, etc. as best as I can tell.

 

[Biglew11]

good find looks like it should work.

Tagging along, really hoping this works. Please take lots of photos so I can share them in the future should it work and someone else wants to attempt it.

I tagged you so you could help me, not the other way around! Haha

I'm pretty confident based on voltage testing the output pins on the relays that the one is bad. Everything lines up. The board also isn't crowded at all where the relays are so the solder work should be easy. I say that not being very experienced, so should be very achievable for most people with minimal soldering experience.

I'll do my best to take pictures of the process and go back and show how I found the bad relay. If everything works, I'd be happy to share my findings and help. If it does, it sure beats the heck out of purchasing a replacement controller. I expect the new relays to be in on Thursday, and I'm anxious to try it so I'll report back after that.

 

[ATI North America]

I agree! And yes I'd much rather be selling you your next light and bulbs not a silly control box. I hope it works!

Why would a T5 light need a relay, or a control board? Is it for dimming? If so, you don't need that feature. Is it for the timer? If so, use a light timer.

Can't you just wire the ballast directly to the bulbs?

Hello Nereefpat,

The LED Powermodule is a controlled light setup with fully programmable LED clusters including color and intensity as well as dimmable T5's (except the 80w version) all operating with essentially a computer program.

You can do things like have the sun come up on one side and set in the other etc if one wanted too.

Can you directly wire your ballast to the T5 bulbs?
Or does a person have to get a different ballast to light the t5 bulbs?

 

[Biglew11]

The ballast is directly wired to the builds. The relay in the controller is between the power cord and the ballast. One new relay about 2 dollars plus shipping. Better to replace relay and retain factory controlls, other wise you're looking at an additional power cord a timer an drilling the housing for another cord.
