Wiring diagram/ladder diagram 2
Wiring diagram/ladder diagram 2
(OP)
I have trouble trying to understand converting wiring diagrams into ladder diagrams. In this wiring diagram it splits into different directions (like most) and it's hard to get a sense of direction to tie it all together. I have included the wiring diagram and an attempted drawing. Am I even on the right track? Thank you.





RE: Wiring diagram/ladder diagram 2
Yes, you're doing OK. You might want to add the terminal numbers on the relays and perhaps number your terminal strip from left to right, 1,2,3 etc.
Give the terminal strip a name e.g. TB1. Use a different symbol for the terminal strip terminals to differentiate from the relay terminals.
Add the contacts and indicate which relay they belong to e.g.
CR1
--||--
Note: Although the contact is NO/NC you only need to show the portion that's wired.
Just scratch it out on a scrap of paper until you get the idea of how it's wired then do a final drawing.

I was away on Friday. You are on the right track, missed a couple of contacts though. I think you probably appreciate how long it takes to draw a ladder diagram, I traced it out myself and it took a couple of hours. I will pdf them tomorrow and attempt to post them on the board (i haven't done that before)
What are you trying to do, code the equivalent into a PLC?

this is my "take" on the conversion.
Hope it makes sense

I draw this type of drawing all the time. Here's my take on converting the drawing.
I labeled the terminals from right to left.
This is a very typical start stop circuit. I imagine the CR's control something else once this is installed.
Good luck!
