Great STUFF !!! Would this controller work for a flood table?
DISCLAIMER: Not sure which sensors the OP states to use, or what everyone else is using.
In my experience, I did fry some sensors. In one of the DIY's, was a link to Chicago Sensor http://www.chicagosensor.com/Miniature_Horizontal_Mount_Float_Switches.html
I used FLT231. If you read the spec sheets, its rated at 100VDC. But we are running 120VAC through them.
I wired up 1 controller and 8 more setups using these switches and the radio shack relay. Once in a while, I had a switch go bad. It really didnt seem like a big deal about the 120AC because it was so little amperage but I am not an electrical engineer.
The switch is a very simple device. If you have a multimeter, set it for ohms or continuity (sp?) and when you open and close the switch, it should beep/shut off or go from 0 to infinity.
After rereading your post, there is no way to reverse the switch.
leave both switches down in the bottom, turn your timer off. That should equate to your buckets draining, and water pumping back to the res. now lift the bottom float up, then the top float up. That should trigger the lamp/pump to come on
Turn the timer on, and leave the switches on the top down. That should equate to your buckets filling and your res pump filling the bucket. With the switches down, the pump/lamp should be on. Now lift the bottom switch, then the top switch. That should turn the lamp/pump off.
Remember both switches have to be activated, thats the whole point of this.
It took me a while to understand this whole procedure but after wiring up 9 of them, it was 2nd nature
Not sure what you reversed, but its possible you blew the relay
yes if the table was on the ground and the top of the table was level with the control bucket so that way you do not over flow the table. You do not want the table lower then the float switches. I know some people going like wtf?? why would you want to use it on a table. One reason I can think of is that you already own a E&F set up but the strain you are growing gets too tall and you need more vertical height. So what do you do? Go buy a new high dollar E&F bucket set? Hell no, just go plug the drain holes on that table, drop it to the ground and make yourself the bucket controller and get growing. Plus you can move your plants around the tray a little more easily until you put up a trellis.Great STUFF !!! Would this controller work for a flood table?
Looks like they changed their design in light of this thread. The new version only has one timer and is almost identical to the construction of the controller in this thread.hi all, can some1 please list all the parts needed to make this controler in uk spec (220v/240v)please please please,really need to make it and make it work proper, HELP help HELP any1
here's a wiring digram
dtfsux- If you're wiring it through a relay you should only be running 12V or 24V through the switches. I can't think of how you would wire it without the DPDT in the relay actually.
I was hoping someone could help me out with a slight modification to this controller bucket.I want my controller bucket just to be a drain bucket. No timer, and no high level high switches. I run trays that are on the ground and drip into them, and just use the controller bucket to empty the trays. I purchased all the supplies i need to make this and thought i could figure out how to bypass the timer, but i am stumped. I would be super stoked if someone could point me in the right direction...
Yeah i put it all together, minus the connections to the timer. What confuses me is the black power cord wire is supposed to only connect to the timer. Where should i attach that to? The white power cord wire, attaches to the relay, the timer and the drain receptacle. I just left out the timer connection for the white wire.
take the loose black wire and the white wire to the timer and put a plug on it and plug it into an outlet.
All the whites are together because they are the neutral and it is common.
The black is hot and is what is getting switched
I am 99% sure that will do what you want.
