Thanks for the suggestion on the indication E.
However i'll have a piezoelectric buzzer attached in parallel with the relay's coil that will sound when the sump pump is off and the air pump is on. Also, the air bubbles themselves are a pretty good indication. Normally the main aquarium will...
Thanks esp1,
Yes the line is protected from over amp. I'll also be using a GFCI device since water is in the area.
I think i'm going to use a couple of extension cords so i do not modify the cording on the sump and air pumps.
I'll have a male end plug into the GFCI outlet that will supply the...
Esp1, I have decided to add an air pump to the equation which will come on when the sump pump is off.
I'm wondering if i can just use the NO side of the same side of the relay that the sump pump is on.
Is there any problem hooking up more than one +120vac to the same common pole of the relay...
esp1 - Thank you for all of your help with this project. That schematic looks beautiful.
I will also put some kind of audible annunciator in parallel with the LED and the relay coil, but i can definitely build that with my limited skills :)
I won't put it together for a couple more weeks...
I think I still need to see the diagram.
However, I think I understand the idea.
12V+ attached to the level switch, a NO 12v relay, and a NC 12v relay, then back to the source in series.
the NO 12v relay will have 12v power on the load side that will supply the coil when the relay is energized...
yes esp1.
I was just thinking about the same issue last night. And if the pump remains off until manual reset the 3 second delay is not really required.
I think the more ideal solution would be to have the float switch trip the pump off instantly, then the pump stay off until some manual...
esp,
Oh, sorry for not being very clear.
For an aquarium sump you have water being pumped out continuously to the main aquarium, the aquarium then over flows and drains back into the sump. So for normal operation the sump pump is continuously pumping and the water level is constant.
the low...
I'm not sure what i'm looking at.
so, i can see what V2 and Relay 400 are in the diagram.
I'm confused at what is happening in the lower left side of the diagram with V1 and line sw1. it looks like it's representing the level switch
I was just assuming the level switch acted a lot like a...
I have considered that, and it may work well at first.
The issue is the aquarium service i'm operating in. The check valve may not have a 100% seal after a few months in the aquarium water has produced biological fouling. The valve would slow down the interval of pump restarts, but may not...
Firstly, I'm not well versed in the electronics world.
The goal of my home project is to provide an electronic shutoff for my aquarium sump pump when the level gets too low.
I'm looking at using a float switch to trigger a 9V power source (battery), the 9V signal will then trigger a normally...
