PLC and Hydraulics Pictures
(OP)
Hi All,
Some of you have been helping me on a project that I've been working on for the last 4 months. Well, I finished the bugger and trucked it to the remote site it will no doubt, live at, for the next 20 years. It controls the gates for exiting drinking water - different levels for clarity.
Here is one picture of it(name blocked out to protect the innocent), and links to some others.
Comments welcome.
And thanks for your help.

RE: PLC and Hydraulics Pictures
There are a few things to comment:
The service outlet (double) is just wounderful to find in a cabinet. I hope there is juice in it when the main switch is off?
Lots of TyWraps there. I would have used light spiral tubing. But, then, that is if changes were anticipated. Knowing you, I can see that you are not planning any changes.
Lots of wire identification, too. Is that what the customer wanted or is it what you wanted? A good thing, absolutely. But it costs.
I am not familiar with the wire colour coding. Is that a US standard? How do colours translate to potential and/or function?

No the courtesy outlet is dead when the main 480V 3Ph is off since it is provided via the 1kW transformer at the top right.
Yeah lots of ties.. :) But really there shouldn't be changes.
There was a labeling requirement by the customer. However I'm sure he was thinking those damnable digits in books. So labeling wire 471 requires you actually put on 3 labels: 4 and 7 and 1. This also provides no information at all.
We had a labeler but attempts to put the labels on the wires when there are a lot together like on the PLC looked onerous. So I gave tywrap flags a try. They are made to be written on with a Sharpie. I was able to devise a code system that was easy to interpret. I can actually tell what each wire does without my schematic.
There are some standard codes but I used the 'what color of terminal blocks can I get' method, and so, the wire matches the terminal block colors. I wanted the differentiation on the blocks because they are pretty narrow and this is where the customer meets the system. This led me back to the wire colors.
The system is 120Vac and 24Vdc so:
Black = 120Vac
Yellow = 120Vac Logic and Switched
White = Neutral
Red = +24V
Blue = 24V Return
Orange = 24V Logic and Switched.

As mentioned in another post somewhere (about another topic)
I think it was promoting your company thread,
"Have a good logo on the cabinet"
Cheers,

Is this the one we had a bet on?
Who won?
I think I remember the stakes were a cup of coffee.

Keep it up! Seems you devote it with passion.
A little comment, wiring are not too well arrange. Be aware to safety.
RE: PLC and Hydraulics Pictures
dbaird; Thanks much for the input! On the "list" you provided, the last item, I'm not sure on; "enclosure type" does this mean NEMA 4X ,12 etc? or?
On the original unit I'm replacing they had taken to writing on the face with Sharpies then to erase the marks they used a can of spray paint... I came up with the double silk-screening (white blocks) which I titled "NOTES". Then I stuck grease pencil on the front hung from a 3 inch chain and a magnet to allow comments to be written in the note areas. Comments like, "leave this gate off!". I'm interested to see if my scheme works.

"Thanks fbcybil; You realize that the three wires coming out the front are just a test jury rig?"
Your welcome! Oh yeah, you're aware of it. Anyway, it's design for its purpose.

Go to the end of the thread and look backwards.

RE: PLC and Hydraulics Pictures
But I forgot none of those jumpers!! Beside I can't stand coffee either. lololololo
BTW: Those switches cost a bundle $130 apiece for the complex ones, but they were worth it because the logic they provide removed all sorts of other stuff. Here's a shot of the replaced system. You can see the simpler result (IMO).

Another code or a sort of multi-standard?
RE: PLC and Hydraulics Pictures
Very nice and neat. I like the distance from floor using a
stool to sit on, prints in my lap and room for meter on
bottom of cabinet....yes I know, no trouble shooting for 20
years!

RE: PLC and Hydraulics Pictures
Seriously, I couldn't agree more. The hydralics people put flags on the uprights. I discussed no less than 8 times with them the location and spacing for the mounting flags. They still got it wrong, so I just plugged the enclosure holes and drilled the box again so I could put the box at a nice altitude.
