one channel stays on


Bruce Ingebretsen

Recommended Posts

I have one channel that is continuously on at about 50%. It is on whether I am running a show or not. If the controller has power, that channel is on. The only way to turn it off seems to be to unplug it.

Any help would be appreciated.

It has a blown triac.

contact LOR support and describe your problem.

I don't think it the same issue. Do you have this check box checked?

If not that could have been the channel that was left on at the end of the sequence.
If this is not the issue then how does it behave in the Hardware Utility?

Replacing a triac is really easy if you have soldering skills...and a new triac!
i haven't had to replace any this year but I keep a few on hand just in case I have issues. Mouser has them for sale.

I'm having the same issue with one channel staying on after the show. I'm blaming it on communication issues and will be switching the phone line going to that controller with cat5 tomorrow to see if this helps.

Do the channels function correctly during the show? Meaning do they do their effects and than just stay on after the show? If they work during the show it isn't a triac issue. It most likely is what was said below about the channels being left on after the show.

I just had two whole boards do this to me.

Is there an issue with unplugging a board while the show is going (to add a Kill o Watt amp tester) then plugging it back in with the network cable still attached and feeding the show to the board? Or do you always have to disconnect the network cable.

I can't find anything in the manuals that this will cause a problem..

I will say...NO there is not a problem with un-powering a board and re-powering with the network still connected. When I have situations where a GFI trips....the rest of the show plays, except what was on the GFI. Reset the GFI and as soon as the board initializes and gets a command the lights play as they should.

Tough to say - it stays powered on the whole show, I think it might be going from something less than 100% to 100% during the show. I have not noticed if it shimmers or twinkles when asked to. What would that tell me again?

Jim,

One other simple test. If you use the HWU and send an off command to those channels that are sticking on. Do they turn off? If they do not turn off. Then I would say you have a bad triac.

Wow, 3 whole boards? All 16 channels? Thats a lot of triacs to be blown. What are you putting on the outputs of these boards? Are you using relays on the outputs?

That is just mind blowing. I wonder if you have gotten some power line noise that is scrambling the PIC (aka brain). Please try a controller reset first. If this works, then I think you might need some kind of line conditioning.

I tried resetting by putting the boards to 00 then setting them back the correct board number per the manual but they stay on. No channel has more than 2 amps on them and most have about .6 amps. Last 3 years no problem with my same power hook up (splitting the dryer 220vac outlet into 2 120vac 30amp).

I have not tried doing a turn off with the LOR Hardware app.
