Excellent lecture. I've not been able to fully grasp ladder logic for a long time--especially holding circuits, but you have explained it thoroughly and in an extremely well laid out and organized manner. Your teaching style is impeccable, thank you.
This is sad and funny to me as a professional technician. I have paid for courses like this in the past, and this is vastly superior. These types of circuits are fundamental, and clear explanations really help comprehension. I am looking forward to moving through your series as I move towards the PLC series.
I don’t understand why more people don’t take advantage of videos like these. I’m studying for a test for a promotion and this video has better information than the electrical schooling I PAID for.
As a person with knowledge in the subject I can say with confidence that the way Jim approaches the subject is the best that I ever seen , this channel is treasure of resources.
This is absolutely amazing tutorial. I have just graduated from college with an Electrical Engineering degree. I want to make my career in Automation Industry. Thanks for the help.
you are so right, the first time i tried to dive right in and understand this it was very frustrating but i put my time in and now its like, yeah this is definitely making perfect sense thank you for making such a good and thorough teaching channel and you cover so very much for someone like myself who wants to jump from being a welder to working with electricity
Thank you for this video. I am a Ranken Technical graduate from St Louis, Missouri. Been out of school for 5 years & most been doing apartment & hotel maintenance. Not much PLC work since my first year out of school. This definitely helped me brush up & get more confident as I prepare to take this quiz for a new job working in an industrial facility. Didn't even have to get out my notes from school, this video helped all the information in the back of my head rush to the front if my head...
An excellent lecture. Well organized and easy to follow. Many thanks for your the time to prepare this video. I am a chemical engineer but need some basic knowledge of wiring diagrams. This is the best material I have found on the internet. Greetings from Poland.
I'm 2 weeks into an introductory Industrial Maintenance Tech course and was having some trouble with the electrical Ladder logic but after viewing this video, I finally feel more comfortable with this. Thanks for putting this out there. It really helps. All I can say is thank god for rewind...
Very nice! Glad you're making use of this material. Please tell your instructors and fellow students know about this resource and make sure to check out the complete motor control playlist at: ruclips.net/video/LM8U9FCMDx0/видео.html
brilliant lecture just in old school jim pytel style. Thank you so much for such valuable contents. You're definitely making this world a even better place.
One philosophical question. When you are good, great or the best at something ( like you ) , how you continue motivating yourself in your life ? . You must continue doing what you do best, or you have to switch and do other task ( like running the University .... ? ). That's a totally diferent topic or question what I'm asking, and luckily, I don't have that problem, because I'm not the best at what I do. But, I like to think and talking with smart, bright, intelligent and great people, and this is something that I like pretty much. As I mention a thousand times to you.... I love what you do !!!!!!!!. And you are the BEST !!!!!!!. Thanks for everyting !!!!!. Pablo.
So glad I found this. My instructor for electromechanical control systems just reads off of power points. He should recommend your video. It's fantastic. Easy to follow and great explanations. Btw, you just helped me with a very similar hw that I couldn't quite figure out. It has to do with 2 solenoids and a light coming on to show which one is active. I think my circuit will work now. I even added the e-stop. 10 million thank yous!!! Subscribed. :)
Very nice! Glad you're making use of this material. Please tell your classmates about these free resources. Here's the complete motor control playlist: ruclips.net/p/PLdnqjKaksr8qRPCFkU2Q8XQe0bfo99rs6
What up? Hey if you’re in town this weekend swing by the campus Saturday for the STEM fair 9-12. You’ll be jealous of all the cool new equipment we have now!
@bigbadtech Would love to! But I live in Phoenix now. Finished a MS in EE at ASU and I work in Tesla's battery dept (Megapacks Utility scale). All these levels of education and CGCC still boasts the most technically adept teacher I've had.
You are good! i was kindof frustrated with the general basics videos that i found about ladder logics and i was wondering why they didn't talk about the actual working ofthe keys, switches and the logic behind it! This has been Extremely Helpful and i'd recommend it to my friends for sure.
Jim, at 16:30 you spoke about a PBX switch which from your explanation i somewhat understand. I want to ask however about control circuits that uses 3 or 4 position key switches that when moved through their positions activate different parts of the circuit. How is this represented on a ladder diagram. Do you have lectures on this that you can point me to. I am currently using your videos to understand the ladder diagram of a control circuit using a four-position key switch.
It gets super difficult after 2 mechanically interlocked switches to draw it schematically so often people revert to using a "contact chart" or "target table" as illustrated in this lecture: ruclips.net/video/ENCdPsA9PXc/видео.html if the mechanical interlock spans several rungs it's often easier to use "house notation" as illustrated in this lecture: ruclips.net/video/f1Lj9I0vX6U/видео.html
Thanks for explaining this. While I am used to reading standard standard electrical schemactics, I had been throughly confused by this weird schemactic that came with a piece of used equipment I had purchased. Now I know what it was and will better understand how to interpret one in the future.
Excellent presentation. One comment is that at 12:05 its mentioned that there should not be an "output only:, I've often seen an indicating light just tied across as a "Control Power Available" indicator,
Outstanding lecture! The hard wired e-stop circuit shown here is the most straightforward way to stop a machine. Also NFPA-79 requires that e-stops be normally closed contacts, and cannot be integrated through a PLC. However, a safety relay or safety PLC (like a PILZ) may be used since they are designed for that purpose. I have seen machines that use normally open contacts for the e-stop and use the regular PLC to stop the machine without cutting power to the control transformer. These will not pass an electrical inspection. Thank you for demonstrating the correct way to control!
True dat! If there's one thing I learned from watching the Terminator is to never trust a machine. Check out the "PLC Interface" lecture at: ruclips.net/video/G4uo0Sm0uMo/видео.html where I expound upon the necessity of a fail safe means of killing a machine dead.
ohhh...im newbie to this channel...i like the way it is to refresh my college days.. but the way you discuss about diagram i noticed you fotgot to label to im losing fucos on where im am in the part of discussion but over all its nice...thanks..
Don't give me too much credit. I just turn the mike on, click record, and make it up as I go along. Just kidding. Thanks for the kind words. Lots of work goes into this material and I'm glad you're make use of it.
Lamp "C" is always on, alright? Just let it drain power continuously until it 🔥 burns out 😂😂😂. It's Title 24 compliant, don't worry. 😉😁 Seriously though, really LOVED the video, TY.
Jim I wanted to say how much I enjoy all your lectures. I wish I had gone to college w you as my professor. I'm very curious about something. Your lectures cover a very broad range of topics. How in the world did you learn all of it? What do you actually do for a living? Thanks!
Glad to hear you're making use of this material. I presently teach for the Electro-Mechanical Technology program at Columbia Gorge Community College. It's a program that really does include a bit of everything: electricity and electronics, hydraulics, pneumatics, mechanics, motor control, semiconductor devices and circuits, digital logic, PLCs, industrial control, programming, and power generation and transmission. As for my professional background I'm a former Captain in the US Army and I've worked in semiconductors and industrial windpower. You can't learn everything at once, however, you never have to stop learning.
Jim Pytel I knew it, ever since finding your videos a few months ago and experiencing your unique style of sarcasm in all of the videos I have watched I figured you had to have a military background. I retired from the Air Force on the enlisted side (MSgt) as a Civil Engineer in 2015 and I have plenty of experience working with the all branches but primarily the Army Engineers and Navy SeaBees during deployments to Iraq and Afghanistan. It’s funny how military folks have developed their own style of sarcasm and you Sir are no exception. BTW, thank you for your service and all of the content you’ve created. I’m definitely trying to make the most of it as I’ve changed careers or fields, I was a plumber and now I’m working as an instrumentation tech in Alaska at a coal fired power plant.
@@AKBRONCOSFAN007 Some people can't handle this level of sarcasm! Check out some of the angry comments in the "Basic PLC Instructions" lecture. It's like they have thin skin or something? Glad you're making use of this material. Lot's more coming your way.
I'll be at CGCC till at least this June. The motor control course is not fully online. In addition to these lectures the course necessitates a bi-weekly face to face lab.
Thanks for the great vids. @10:30 Could I actually blow a fuse in real life by only writing in a push button on a ladder rung all by itself? Or does that just mean that technically in real life a switch from X1 to X2 with no load in between would be a short circuit. I'm just wondering how the PLC works on the inside. I'm thinking that we are basically just giving this PLC logic to solve and that would be what determines what it does. Since there is no load on the rung I was thinking that PLC would do nothing. But now I'm wondering if that would just be giving the PLC instructions to short circuit itself. Ok another question @11:10 I see the part where you are talking about putting to lamps in series with one another. Does that effect the voltage coming out of the PLC? I would know not to wire the lamps in that way because then the voltage would for sure be wrong. What if we had different plc adresses for each load would that technically work but we just shouldn't do that. Or do we just not do that because everything needs to be properly documented? I am new to all of this so I apologize if I used words incorrectly.
All good questions ... however ... this lecture deals with hard wire relay based ladder logic (ie: real devices wired in series and parallel) and NOT the programmed instructions inside a PLC. There's a big difference between the two. Here's the full playlist for hard wired relay based ladder logic: ruclips.net/p/PLdnqjKaksr8qRPCFkU2Q8XQe0bfo99rs6 Once you're done with that here's the PLC playlist (in development): ruclips.net/p/PLdnqjKaksr8qxlMYRVTF2YzTm6RwtA7pc
Nice explanation, but in the example at 25:53 where you added the stop push button; be represented with the push button on the bottom of the ladders rung to illustrate that you are actually pushing rather than pulling? Judging by only a few moments later it appears the stop button you created penetrated the rung to stop operation. Maybe it doesn't matter, just an observation, I know breakers in simplified form can be shown as a stop partition that is on top of the rung, but those are also generally on the right side of the rung too, like the relay.
Thank you for taking the pain to do this beautiful lecture going from the simple circuit to the complex ones. You are speaking too fast though so I had to slow the video in order to keep up. Thank you so much.
the first stop button is on the wrong side, it is a normal push button that opens the circuit if you push it. the lock has to be the normal closed button which should be underneath not on the top. when you push it will not open, as shown now it is at the top so if you push it it will do nothing. it has to be underneath so that when you push it, the circuit opens.
Thank you for replying so quick. I’ll check out that playlist now. Might have a few questions for you later on so I’m sorry if you start see too much from me. Again, thank you.
If you can understand this, troubleshooting will come easy to you.... I took a course similar to this for industrial electrical services and since then, if you give me the diagram and schematics I can troubleshoot with the best
