anyone tried to using Jebo WP40?

[Sacohen]

I tried to post pictures to this to show how I have mines hook up, but they are too big. I think the sensor being on the side of the controller is the problem. I have mine inside the tank pointing a little away from the LED's. When my white LED's are on the controller is working in day mode and when my white LED's goes out it goes into night mode. The blue LED's have no effect on the sensor as they are on for an hour after the white goes out and the controller still goes into night mode. In the morning when my blue LED's comes on the controller is still in the night mode until the white LED's comes on. I have one sensor hook up to 2 controllers and I haven't had a problem since I put them on the tank.

I have the same issue, but when my blues actinc's go out an hour after my whites, it goes from night mode back to normal mode so it is running normal all night long until the blues kick back on at Noon, then it goes to night and when the whites come on at 1pm it goes to normal.

Just got my pump yesterday afternoon... I thought I had a defective pump/controller, but it was the power cord! How do you send a power cord that dosn't work!!! :angryfire: Kinda funny though, I unplugged the one from my MP60 to start the trouble shooting out... lol:lolspin:

Kinda like cannibalism :blown: on the MP60, the jebo has me almost ready to pull the trigger on a ReefAngel and another wp40... and sell the MP60 :eek1:

EDIT: I am going to try and pick up a 100K and 200K pot today from the shack and try them out, if they don't work there I will try to mod a photocell like mentioned earlier...

This is a common issue. I had it happen to me and I've seem 3 other posts of people how got a unit plugged it in and nothing then they replaced the supplied US power cord with one from a computer or something else and it worked fine.
Fish-Street.com is away of this and said the following in my e-mail to them...

Thanks for you quick reply for us, we have already report on the factory and change a new power cord now~

its funny watching my fish swim through the wave it puts out in the tank .. i guess they feel like they are back home in the ocean .

My clowns love it. They just surf the wave, but sometimes it kicks on when they are not expecting it and they get blown across the tank.
they just get back in the stream and have fun.

lol same with my sohal sceohon .. she is playing it in like she is home in the red sea again ..

I will check mines tonight to see if it comes out night mode when the blues goes out will let you know

 

[wgraham]

My tank is also in a wall so if there is any light in front of my tank it does not affect the sensor because it can't see the light as it is also behind the wall in the tank. But will check to make sure that it doesn't come back on.

I got mine from ebay already.

Got it in 2 days and I gotta say this thing is pretty awesome.

I had to buy a dimmer switch due to having way too much flow in my tank.

Good luck getting any support on it if needed.
This is probably some one who bought a bunch of them from Fish-Street.com an is reselling them.

According to Jebao, Fish-Street.com didn't even buy the product directly from them and Fish-Street.com and Jebao have not amazed me with their customer support of the product.

Only my opinion, but I know a couple of other feel the same way.

Good luck with it.

@ Sacohen.....Mine is doing the same thing. When the white channels on my EG leds goes off and the blues stay on- the sensor works but when the blues go off and the room is dark it switches back to whatever mode it was previously in. I have a power strip close to where the controller was. The strip has an illuminated on\ off switch that has a faint orange glow when it's on. By placing the controller close to this faint light it has worked great two nights in a row. Matter a fact I had just went down stairs and checked to make sure it was. Maybe a dim night light near the controller would do the same for those who are having the same problem.

I'm going to try moving my moonlights forward a little bit so they are in front of the sensor. Maybe that will be enough light to keep it in night mode.

It is advisable to use PWM to control the pump. It is designed to run at 24v and only 24 volts. You can reduce the voltage to reduce the speed, however it will increase heat and is not the right way to control a DC motor. PWM pulses 24 volts which therefore controls the speed of the motor. The cable from RA will correctly do this via the built in box when hooked to a RA or Apex.

Are you saying that it is advisable to utilize the dimmer over the PC adaptor? I am confused because in both instances it seems the voltage to the pump is being lowered to control the pump speed.

Yes, the lower voltage will work, but that's not how it's supposed to work. You *can* adjust the voltage to control the speed of the pump, but it's not advisable for the reason stated above. What you should do, and the stock controller does this, is supply a control voltage to the VA line, which in turn adjusts the speed of the pump through PWM. You could theoretically bypass the VA line and supply your own 24v PWM signal directly to the motor to control it that way, but I really don't know what is in between the VA line and the motor. Could be a PWM generator, could be a mosfet.

I appreciate you trying to explain but I am not following you....could you express in common layman's terms? Is the simple LED dimmer a better fit than the variable power supply from Amazon that has been mentioned here OR are both an improper fit due to unknown specifics?

Both are improper. If you want to control this pump the correct way, you need to send a 'dimming' signal the same way the stock controller does.

If my second pump would ever show up I can get it hooked up to a scope to see what's really being sent from the controller.

0-5 VDC analog. There's a big discussion about it on the Reef Angel website. They've already got it working with the RA.

Just got mine and plugged it in... am loving it so far!

I know. I have not read that thread but you are correct, it is 5V analog going to the VA line which can be achieved through the proper construction of a low pass filter, but what frequency is the signal? So far that has not been mentioned in this thread but it is important to prolonging the life of the motor.

I'll go lurk that thread to see if I can find out what I'm looking for.

So will installing a pot in line with the controller cable 0-5v wire and using the existing controller work also?

I think someone tried, or said it wouldn't work, for a reason I can't remember. It's in this thread somewhere.

I'm confused on your request of a frequency... analog signal would not have a frequency and would be a true steady voltage

I don't understand it 100%. Talking to a few guys at work in our motor control department, if I understand correctly, passing a PWM signal to a LPF would smooth out the signal which would then be averaged, but there would still be a frequency. What we don't know is how the pump is actually controlled on the inside. How does that 5V control the motor? As you stated earlier, 24V PWM is the way to control that motor, so where is the PWM coming from?
