Channel comes on in rain


Recommended Posts

I didn't think it was a relevant point jer...oops, wrong thread. Just switching the channels, whether it works or not doesn't explain the problem.

How many C9s do you have on that channel? Maybe you just happened to toast a triac on a rainy night.

My numbers say 140 C9s gets you around the 8 Amp limit per channel. But maybe the triac isn't mounted properly, maybe it was flawed, or maybe the rain started to short that channel out.

It's one of three controllers that I didn't cover. They're protected by an overhang, but maybe the wind driven rain got in it somehow. it's just funny how it's only one channel.

So you folks protect your boxes, other than just having them in a weatherproof box?

I've never done that, but we don't get a lot of rain here in December (but it does happen)

Okay first: I have my c93 really spread out. That particular channel only has a section of about 30 on it. And remember, this didn't happen during a show, when the show was over everything was off and fine. The rain didn't start for a few hours after.

Now here's an update. I just plugged the controller back in. Same story but I discovered there was another channel doing the same thing, I probably missed it before beacuse it's a bush and I really didn't walk over to that section to see it. Anyway, I powered down again and disconnected the cat5s and powered back up, same thing. I ran a sequence and everything worked fine except those two channels although they would go up to a hundred percent, still wouldn't go off more than probably 50%. I opened the box to look for moisture but when the box opened some water from the case got in. I got my leaf blower and hit the inside of the controller for a good few minutes. then I did it with a hair dryer. Hooked everything back up and everything works right again. Would I be correct in assuming that some moisture did indeed get in the enclosure and was "arcing" a circuit or something? By the way, both channels were on the same side of the board.

Probably (although technically not "arching", but somehow partially completing the circuit). Sounds like everything's good to go, although I would look at protecting the enclosures a bit better if water is getting in somehow... Plastic bags might sound silly, but they work great (I use them to protect lots of stuff...)

I didn't do it last year. I covered some of them this year but not to protect them, I covered the ones that are out in the yard, more for aesthetic reasons.

My guess would be that something got on the board that you removed (moisture, flux, slugs, bugs

I'm sorry, but I find gray boxes throughout the yard to be quite festive

(oops, wrong thread)

Has anyone contacted LOR about this? All kidding aside, this sounds like it could be a safety issue. You have circuits that are off, but there is still current flowing? That's not good.

Someone posted last year that they tried to fix a wiring issue with the controllers powered on but the lights off, and they found out the hard way that there's still juice flowing to the lights, even when they're "off". It's a property of how the triacs are fired...

Even if that weren't true, I'm not sure what LOR would do about it -- if the board gets wet, funky things are going to happen :) Worst case you could send 120V back through the com line and fry everything (including all controllers and your PC) but the way the board is laid out, that would be pretty unlikely.

I've had water get in the weatherproof boxes. Most of my controllers are covered with either a plastic bag, or inside a present.

But that's mostly so they don't stand out so much. The secondary waterproofing is a bonus.

I dont think I had the same problem, but this morning (in South Florida) I was sitting on the porch drinking coffee at about 5am. There was a cool front coming in and I noticed an occasional flash, but no thunder. When I walked down the driveway and looked back for lightning I noticed a strobe fired off. A short while later it did it again. I have about 20 strobes around the yard, but the same one fired about 3 more times, none of the others did. They are all on the same channel. Is this caused by static electricity? There was a storm approaching.:giggle:

No LOR here. My controllers are all DIY Renards.

Yes, moisture can cause a channel to com on or partially come on. You can cover them with bags and they still may get damp inside. In funky wet weather condensation can form if the board is warmed and cooled.

Many times when they dry out everything will be fine. It is possible that a Triac could be fried. I replaced two on one controller tonight. I noticed a couple days ago these would sometimes act up. Finally they were just stuck on at about 50%.

Other than the fact that a channel stays on dim, it really should not hurt anything. If the moisture was causing problems with the low voltage side of the electronics you would have more problems than a channel just stuck on.

If you have an extra channel, use it. Just remember that there is power on that line all the time.

And your issue with the strobe could be similar. Static won't cause a strobe to fire. But high humidity might. Just a trickle of juice going to a strobe would cause it to fire every once in a while. It would not need to be enough to even begin to light LED's or incandecants but a strobe is designed to store up energy and release it when it get to a certain level. Watch how most strobes will fire once or twice after the power is turned off to them.

Ha - you giggled at me when I unveiled my methods in camouflaging my controllers. Who

I know my controllers work good in the snow, because right now we are in a snow storm. We shoveled our sidewalks 6 times already. Snowing like mad. C7 arches sure look good with snow piled up between the lights......gives that glow in the snow.

After the snow comes the real cold and not this mild 25F we have now.....but Monday we are looking at -20F.

I maybe should not have done this, but I did it anyways. I ran my lights in a light drizzle last Saturday. Then I did not run them the next day, and then ran them the following day in snow.
