View Full Version : Problem with controller/outlet?

10/17/2011, 08:30 PM
For a while now I have noticed that while off I will have things plugged into my DC8 randomly turn on and off. I noticed first a few months ago with my sump light but just thought it was a problem with the light (old crappy work light). I recently upgraded my main lighting to an Orphek DIF-100. The outlet it is connected to has a simple

If Time 10:00 to 20:59 Then ON

In the last 30 minutes I have seen the light flicker on and then instantly off 6 times. What could be the problem? I am worried that this is actually happening to everything I have connected and could cause some of the hardware to fail prematurely.

Ideas? Things to test?

Is it actually a DC8, or do you mean EB8?

10/17/2011, 09:28 PM
sorry I mean EB8. I always get the two mixed up ><

Check the outlet log, and see it those sporadic events are logged.

From the DataLog for the last hour.

22:00 10/17/2011 82.3 8.44 0.0
22:10 10/17/2011 82.3 8.41 0.0
22:20 10/17/2011 82.3 8.40 0.1
22:30 10/17/2011 82.3 8.39 0.1
22:40 10/17/2011 82.3 8.38 0.3
22:50 10/17/2011 82.4 8.38 0.3

Unless there is another log you would like to check (via web interface).

I have the latest firmware and just updated the log interval to ever minute to help catch the problem (though I believe the .3's are the flickers)

Outlet log, not datalog... found under XML.

You can use the outlet log processor on http://www.reeftronics.net to make it easier to read.

The only two entries for the MainLED are:
<date>10/17/2011 10:00:00</date>
<date>10/17/2011 21:00:00</date>

So nothing to reflect the flashes I have seen. Next idea (I will check in the AM off to bed now.)

Ok, so according to the Apex itself, they are not turning on and off except as scheduled.

Make sure all all Aquabus cable connections are snug. If they are running next to other cables, try separating them. I'm off to bed too. If I think of anything else, I'll post tomorrow.

I will double check all the connections tonight when I get home. The only other thing I thought to do last night was to unplug the fuge light (which has been turned off at the light for a few months now). I should also manually turn the outlet to off.

I think there's electronic noise that radiates from an outlet running high-voltage lights that sometimes impacts a TRIAC outlet causing it to go ON/OFF either fully or partially.

Sometimes moving plugs around or putting the plug on an outlet strip that's then plugged into the EB helps.

Currently I have the following plugged into my EB (in this order/slot).

1) Heater (Temp control)
2) Closed Loop (Time control)
4) Fan (Temp control)
5) MainLED (Time control)

I have cleared the programming on outlets 3, 6, 7 ,8 (put them all to Fallback off and set off) as well as manually turning them off. I won't know how it does until tonight when the LED turns off.

Double checked all connections tonight and everything is snug and good. A few of the electrical wires obviously run parallel to each other, the light however is not parallel to anything. Other thoughts? I guess I am just really worried about frying the new light I just bought ><

10/18/2011, 08:43 PM
It won't be the wires if it's what I'm thinking of. It's internal noise. Try putting the offending device on a small outlet strip, then plug the outlet strip back into the original outlet. Just see if that helps at all.

10/19/2011, 08:33 AM
I will give that a try tonight and see what happens.

Plugged the light into a power strip, plugged the power strip into the outlet and still getting the random flashes. Next idea?

Is this the LED light that's flashing or your fuge light?

10/19/2011, 08:37 PM
LED light, the fuge light is completely disconnected right now. There is a chance my closed loop is doing this as well, I just don't notice it since there isn't a bright flash when it kicks :)

Well, the only suggestion I have at this point is to put the LED on #8, copy/paste your program from #5 to #8 (I think it's currently on #5) and see if that helps. That's a mechanical outlet and there should be no current leakage possible (if that's even the problem).

If that doesn't work (really, if it works also) then I'd email Neptune and see what they say.

10/20/2011, 08:46 AM
I did that last night and will see how it goes today. After I see I will email Neptune and see what they suggest. It seems to happen more the hour after it turns off, and the hour before it goes on. I don't know if that is because I am not up late/early enough to see it more. I guess I will find out this weekend for sure.

We had a similar issue with a dosing pump which resulted in an overdose in the middle of the night. Twice now the pump has turned on when it should be off. Fortunately the second time it happened I was there to see it, however even when I set the pump manually to OFF it was still running! I unplugged the pump to stop it and called Neptune Systems. They told me to use outlets 4 or 8 for the pump because they have a relay switch and can handle up to 10amps. We're monitoring it for now...

Plugging it into 8 seemed to work. I am still going to go ahead and email them as it seems kind of weird to me.

Me to.
