Dimming Expansion module not working properly

Post by lmolenmaker »

Hi Guys,

I have my Reefangel for almost 2 years now. I have my WP25 hooked up to the dimming expansion for more than a year now, with no problems.

Lately I have noticed that at random times the pump is on continuously when it suppose to pulse. I also noticed that the pump didn't go at all at times when it suppose to be on. When the above happened, I checked the DC pump screen on the reefangel and it displays exactly what it supposed to do, same for the dimming channel screen. So the Reefangel is sending the correct information to the dimming channel.

Now when I switch the power of the dimming expansion module off and on again, the pump does exactly what it supposed to do.

Any suggestions?

I look forward to hearing from you.

Start by checking if there is any bad connection or water damage.

No water damage Roberto.

How do I check a bad connection? Do you mean replacing the usb cable of the module?

Roberto,

This is what I noticed, very strange. When the problem occurs, I switch off the power of the dimming expansion module, result nothing happens. When I leave the power on and take the little power plug out of the expansion module, result things back to normal.

Is something wrong with the module?

I look forward to hearing from you.

What is the little power plug that you are referring to?

Roberto,

That is the other end of the power supply cord for the dimming expansion module.

How often does it happen?
Do you also have other modules?
Can you inspect closely and see if there is no salt spray anywhere?

Roberto,

I have a water level module as well. And an expansion hub. Only my Jebao wave maker is connected to the Dimming expansion.

There is no salt creep or water damage, as my electrical cabinet is separate away from the tank and sump.

The problem occurs randomly. Maybe twice, three times a week.

Did you try moving that to a different USB port or try to use different USB cables and secure them so they don't move?

Roberto,

Sorry it took so long to reply, been away for a while.

Yes, i tried different ports and cables, with no luck. What I noticed now is that port 5 is clicking on and off as soon as I switch on the power of the dimming expansion module.

At the moment I have the following piece of code for my 3 pumps. They behave erratically and not with a consistent pulse:

ReefAngel.PWM.SetChannel(0,ShortPulseMode(10,90,50,false));
ReefAngel.PWM.SetChannel(1,ShortPulseMode(10,90,50,false));
ReefAngel.PWM.SetChannel(2,ShortPulseMode(10,90,50,false));

Is my dimming expansion malfunctioning?

Any help is appreciated. Thanks.

That what it looks like for some reason.
Open the case and let me know which revision of board you have.

Open the case of the ReefAngel or open the case of the expansion module?

And where can I find the information, what do I need to look for?

Hi Roberto,

Sorry, was out of town for business.

I opened the dimming expansion and it says: Reef Angel Dimming Expansion 1.2

Hope this is what you are looking for.

I look forward to hearing from you.

Yeah, that's what I wanted to know.
That is the latest revision. I'm not sure what is wrong with the module.
PM me if you want to send it back.
Roberto.
