ATI PowerModule setup question

[PUParrothead]

Picked up my new 10x54W PowerModule over the weekend and I have a question on the setup.

The cord from the fixture goes to a small box which splits into to plugins for the various bulbs. There is also a small socket on this box. I assume that this is for the DC adapter that came with it for the fans. Correct? The adapter had several different tips that were not clearly documented, but only one seemed to fit so I'm using that one. Unfortunately I haven't seen any movement out of the fans. Should they be running all the time or do they only come on at certain times? Also, does it matter which way the tip of the DC adapter is put on?

Thanks for the help.

The small socket is for the DC power. The fan will work only with the right DC polarity; you'll need to play with the pin orientation to get the right polarity. I have my fan power up and off with my first set of light instead of letting the fan run 24/7.

So to switch the polarity I just flip the tip over and the fans should come on? I thought I tried that but I'll check again this evening. The fans start up immediately when you plug them in?

Yes and yes. My instructions when I received mine had stated exactly which tip to use.

Also sometimes the fan covers that say ATI on them need to be lightly lifted away so the fanblades don't have any pressure on them,then just give a litlle lite turn to help them along.

+1 on the ATI logo covers.

Pretty typical when shipping a PM.

Ok, figured it out. There was a little covered panel on the converter that was set to off, I changed it to the recommended 4.5V and things started working. Didn't see the panel at first and it wasn't mentioned in the instructions grrr. Oh well, every thing looks good now. Thanks for the help.

Hi,
Where did it say to set the fans to 4.5?

It's recommended to set the voltage to 7V or 9V for higher air flow to better cooling the lamps....especially in summer.

[tatoofr]

lost me, how do i set the voltage

[jusn317]

I also just received my powermodule last week. Took me a few hours to find that hidden switch on the converter too.

[PUParrothead]

It said 4.5V was recommended in the setup section of the manual. If you are suggesting the higher voltages for more speed thus more cooling in the summer is there any concern that the fans would wear out?

The voltage can be set by peeling back the black plastic cover on the adapter itself. Then there is a slider that you move to set the voltages.

Great Question?

Hate to jump on thread but since this ATI owner, thought I would ask, Is the ballast built into the unit or is it seperate?

[tatoofr]

The ballasts are built into the unit.

[drtrash]

Nice, I wish more products were this easy. Never enough room in cabinets. How much would a 24 or 36 in poweremod or sunpower weigh?

[tatoofr]

Hi,
Dont know , but my 48" 8 bulb weighs about 40lbs.

[drtrash]

Thanks, that is quite an anchor, forgot ballast was built in
Thanks

Does the fans blow the air into the bulbs or suck them out?

[tatoofr]

They blow in.

[tinnghe]

That is strange cause mine is blowing air out

[tatoofr]

Either you have to switch the plug around or you are feeling backflow. when you put your hand on the side of the fixture do you feel air blowing out.

[Versus]

take a piece of paper and make sure of the direction it is blowing also .. the fans are decent and sometimes the air movement can feel like its blowing/sucking and viseversa viceversa v.. that word that is like the reverse of the meaning but the same and such.

[tinnghe]

Strange thing is that when I first have it the air was blowing in and now is blowing out. I went from 4.5 to 7 could that make the diffrent

[tatoofr]

the speed will not change the direction
