Small Fishroom Construction pics

[ronrca]

Some more pics to update the automation process. We are not quite done as the sensors have to be redone. This pic is of the sensors. Very simple technique being used. Im using titantium rods that are also used as grounding probes in saltwater tanks.

The short rod on the right is the high water level sensor. The middle rod is ground and the one on the left is the low water level sensor. The way it works is the same technique used in the Aquatec Tank Level Controller (TLC) for RO systems (http://forum.simplydiscus.com//showthread.php?t=38410).

Both Solenoid valves connected to the power supply and ready to be used. You will notice that I still have the ball valves. I think they are still necessary for back up and if the solenoids require replacing/maintaince.

The wiring for the solenoid valves and sensors.

Thats it for now! Hope to have more soon!

Well, its been awhile since I had a chance to post an update. I have not been able to work too much on my fishroom setup however did manage to get 1 tank fully automated for my trial. I have been using this PLC for at least 6 months now. I just need to buy more float switches now to get the other tanks fully automated.

Here is a pic of the beast that runs my wc's. Its a Siemens PLC and works absolutly fabulous. Underneath is the battery backup and the switches that manually control all the pumps and lights. The push button is used to start the wc's.

Here's a quick pic of the float switches that I am using. I will try to get a pic of them installed as low and high lvl. The operation is very simple as it functions like a float valve however instead of actually closing a valve, it sends a signal to the PLC. I bought them thru omega.ca and they are not too expensive.

Here is a quick pic of the 2 65s that are running. O, btw, I have my own digital camera now so taking pics will be much easier.

Can you post a schematic diagram of your control system?

[john2gs]

Nice Set-up bro Ronrca!

and yeah...pls show us the schematic diagram of your set-up!

[Barb Newell]

AMAZING RON!!! If you ever want to visit ..... LOL I'd like my fishrooms like that!

Joe... Ive got some nice black veil babies available.

Thanks! I hope to slowly continue building however Im already cramped for space!

I dont have a PLC schematic diagram.........yet! I'll try to get one done. I do have a fishroom schematic, block and wiring diagrams for the plc though.

[ronrca]

A simple block or one line diagram of the connection to the plc, valves and pumps.

[ronrca]

And a very simply wiring diagram for the plc. Im not sure entirely sure if I labelled the inputs and outputs connectly. To be honest, I check starting wiring and terminating. I also had the help from my brother inlaw to write the program since I learned many years ago on the Allen Bradlys PLC rather than Siemens. That saved me alot of research, studying and a whole lot of time.

Great job, nice diagrams.

THanks Ron, very nicely done
