Excellent video! I am so thankful for this video! I’m in an industrial electric class and have a new teacher that didn’t receive all relevant resources. There is no curriculum to teach… only labs handed out for us to google answers and wire as per drawings in the lab… sure we are learning, but we need a concise lesson in order to understand them. This video is absolutely great and even having a decent background understanding and familiarity with ladder logic and wiring, I felt overwhelmed with the connections being made in my head watching these videos!!! I will probably watch each one several times!!! Just so short sweet and tied in a bow in only 5-6 minutes! Priceless!! Thank you thank you thank you!!! Please keep it up! You have a gift! For Gods sake sell your videos in different series to small regional trade school/adult education type programs!! Thanks again! I’m sharing your videos with the administrators of my industrial electric class and of course my classmates! I can help drive views of your stuff but only you can really cash in on your gift to teach!!!!!!!
Great video! Ive had 3 people explain to me what a ladder logic is and watch a few videos and im still confused of how it works. This is the best explanation video ive watch! My light bulb is on now. Thanks!
Your a very wise teacher , your conscious of things that may hang up a new thinker and you break down the intellectual hang up ups . Like when you make it a point to show us "We just chose contact 1 but it could be contact 2 we just have to label it something ..."
I dont mean to be so off topic but does any of you know of a tool to log back into an Instagram account? I was stupid forgot my account password. I would appreciate any tricks you can give me
@Aries Royal i really appreciate your reply. I got to the site thru google and I'm trying it out atm. Looks like it's gonna take quite some time so I will get back to you later with my results.
Is it safe or ok to run 120 volt contactors and switches on a control box ? Can i use things like time delay relays as relays or is it best to drive contactors wit them ? Im worried a 120 system would burn up a coil on a normally closed contactor if it was held up for 3 hours . I feel like a 24 volt coil would have a higher duty cycle
If I understand correctly, between the physical switches and the make and brake symbols of a plc, the bits mediate. The bits have an initial value of '0', so it coincides with the normally open state of a contact, while the same is not true of the initial closed state of a contact in the ladder diagram, which for any contact to open, the input bit must change from 0 to 1
Hello Pedro. Yes I do, but it depend on many things. PLease email my Humber Collage email and we can go over exactly what you are looking for and I'll see if it is possible. Humber Mail: lars.kristjansen@humber.ca
Takes me back to the 70's when I used to service the old electro mechanical pin tables. There's more than a few' logic relays' in those old babes I can tell you, the schematics look like a plate of spaghetti. Solid state was the death knell for me and those things, where's the romance in a circuit board full of unserviceable chips?
greeting sir can help me to draw for a plc ladder diagram of two push buttons with three pilot lamps, in that when button one is pressed and released, lamp one lights and stay ON, when same button is pressed and released for the second time, lamp two lights and stays ON, also when same button is pressed and released for the third time, lamp three lights and stay ON .BUT when the second button is pressed, all the lamps goes OFF THANK YOU AM PETER IN UGANDA
Love the energy of the lecturing there and finally someone with solid grasp of English language.

Lars makes sense of relays, momentary buttons, NO/NC etc for me. Thanks Lars.
I really loved the enthusiasm behind your explanations. It made it fun and easy to watch. Time to embark on watching every video of yours.
I would kill for an instructor like this at my university. His way of communicating is digestible
Ha ha ha ah! That's awesome feedback Sean!
Thanks!
Amazing thank you for clearing my concepts!

Great video, easily explain it
This is a really cool video.
Thank you so much for this.
Superb explanation 👌
Fantastic video. Please do more of these type of videos .Good explanation
I turned the 999 likes into 1000😊 A good and simple to understand explanation.
I'm following a mechatronic diploma and your videos are really helpful. I'm the 500 subscriber
Yippee!!!! Congradulations on being $ 500!!!!
This was a better explanation than my teachers boring meeting
what a great video.
Thanks Elliot!
Perfect👍
Verry interesting 😊
Thank you Prof Lars, this is really helpful. Very well explained and completely uncluttered my mind on understanding the basic relay principle!

@Aries Royal It worked and I actually got access to my account again. I'm so happy!
Thanks so much you saved my ass :D
@Travis Kyson happy to help =)
Very, Nicely done!

Really nice. Do you offer a training course?

Question.
If L2 is energized by RC. Then how is a NC L2 energized with the Contact to RC is Open?
Thanks for the great Video!

YES

Thansk for the props Vinuja!
If i was a teacher i would be exactly like this
Well then, you should be Dylan! Teachers are born, not trained. If you feel you have it, then you have it! I know I do
😆
That squeeky marker made me cringe.
Can't stand the squeaking.of.the marker.
That's because you don't like chewing rubber 😂😂😂😂😂
Lol
you are racing what you are teaching. some people are not learning anything you are going too fast
