Unique Jebao DCP pump issue and controller swapping

First off, Jebao haters, no need to post on this one, thanks. I'm looking for helpful answers to my specific questions :)

I had a Jebao DC-6000 return pump for a long time, it worked great, however, it finally died and I replaced it with a DCP-8000. In the process, I discovered a unique issue. My reef angel controller is set to restart every morning at 7:00am, and I find that when the power cycles quickly as it does when the controller restarts, the pump gives an Err 001 code and stops working.

Of course I could set the controller so it doesn't restart, but if the pump stops anytime there is a brief power cycle then that is an issue of real concern.

I'm wondering if anyone else has had this issue, and if they have a solution. The only good option I can think of is use a battery backup.

Also, I'm wondering if anyone has seen this issue in the DCT or DCS versions?

One more question, I'm wondering if I can use my DC-6000 controller on the DCP-8000 pump.

Thank you!

Ted
 
dc and dcp controllers are incompatible, but dcs and dct I think should work with dcp (never actually tested this, so I can be mistaken).

Is the dcp simply using an outlet from your controller. If this is the case, i think the issue is with the controller. I think it is not a good idea to shutdown/restart that quickly. Besides, why the need to reboot the controller? controller instability issues?

I think the firmware of the dcp is too sensitive and gets into er01 state too easily.
 
Thank you for letting me know about the compatibility between models. I was hoping there might be a chance I could swap controllers between models, but realized it was a long shot.

Yes, the controller cycles the power. I have a good reason for cycling the controller, but I won't get into that now, it is kind of complicated, but there really are no problems with the controller.

Thinking it through, having a controller that could quit working any time there is a brief power cycle for any reason is a pretty big risk. Unless I decide to put it on a battery backup I don't think I'll take that path.

Anyone know if the DCS or DCT models have this same issue?

Thanks!

ok, you programmed the reboot.

without knowing any details, using reboot to fix a problem is never a proper solution, regardless of your reasons.

the jebao controller has a large capacitor at the dc input. open up your controller and see. There is space to connect 2 large capacitors, and it may only contain one. You can get another capacitor of same spec and solder it to the second spot. This might be enough to fix the problem caused by the reboot.
 
Yes, I programmed the reboot. Here's why. I turn my wifi router off at night sometimes, and the controller won't reconnect on its own sometimes without a reboot. I'm sure there's a better way to do it, but that's what was suggested to me on the Reef Angel Forum.

That's a great suggestion regarding the capacitor! I think I will try that!

I really appreciate your help!

The Jebao DCP-8000 controller has issues. Mine constantly used to get the er01 error code. I started a thread over at http://www.reefcentral.com/forums/showthread.php?t=2633893 trying to figure out what exactly is causing the issue. I know your issue is slightly different since you are manually cutting the pump off but there may be some good info there for you.

I gave up on my DCP-8000 controller and purchased an Aqualink A1 to control it. Have controller support now and it hasn't errored out on me yet. The verdicts still out since it's only been a few weeks but hopefully the stability continues as I really do like the pump.
 
Your situation is different because you power down the power supply.
Approx how long does the power cycle take? The caps may be able to hold the power a few milliseconds only.

Here's another idea, since you programmed the reboot, then you should be able to program to power down the pump, reboot, then power up the pump. or just simply power down and up the pump to clear the er01 upon startup.
 
The power cycle is very brief, maybe a second.

I like your suggestion, and have thought about programming the controller as you suggested or in a similar way. I'm 50/50 whether I will keep the pump or return it and get an older DC model that is more stable. I'm primarily concerned about an unplanned glitch in the power that could knock out the pump, and if it happened at just the wrong time it could end up being off for 8-10 hours before I'd discover it, long enough to harm tank livestock.

It looks like the A1 would fix the problem, but I'm not willing to spend another $70-80.

Why not put in a buffer period on startup of the reef angel? I haven't gotten very deep into programming on mine, but it seems like you should be able to program in a short delay on startup of the controller. So when the controller starts up, it delays the startup of the return pump for say a minute, or however long you want. That way, if you do have a power bump, it will act the same as your reboot.

I just ordered one of these for my tank, and without knowing for sure, I would be inclined to say that none of the other controllers are compatible. They main difference on this series is the sinusoidal motor control instead of pwm. Previous models all use pulse width modulation. I'm not a drives expert, but I would think that would make other controllers incompatible.
 
I have a DCT15000 and it gets powered down due to lightning storms here in SW Florida. Very often for just a second and occasional for longer. I've never had any issues with the pump starting up on it's own.
