Hi I little confused now , I learn electrical installation Level 3 , but I never did before very difficult, some people working on trade is very easy.

There are lots of people looking for experience. Lets hope you get someone who can offer you some.

Do you have a question on the Direct OnLine Forward/Reverse schematic?
Do you need it explaining to you?

Also, why not try and get into the Trainee section of the forum.
 
Hi what part is it you need help with? Did you tell your training provider your not happy with it?
 
Ok, I will explain how the circuit above works.
This is just the 'control' section of the motor.

You have 110V going through the Stop button and Overload contact. It stops there as all the other contacts are Open.
If someone was to press the Forward Start button the this would make the circuit going through the Forward Coil and energise that contactor. This would also make the Normally Open Forward contact close, latching (locking closed) the circuit through the Forward Coil, so when the Forward Start button is released the Forward N/O contact (which is now closed) keeps the circuit.
TO open the circuit the Stop button has to be pressed or the Overload contact has to open. (This happens the the motor detects an overload)

If someone now presses the Reverse Start button then the Reverse N/C contact opens the circuit for the Forward section and makes it for the Reverse section of the circuit.

Yes , I tell them because they give me drawings and that it , nearly 20 people, this is courses for adults learning not for professional people, I can’t doing too fast because I doing different jobs now ?

Don't leave the course, especially if you have already payed for it.
You may just have to look though YouTube & Google sites to find the information you want and to understand it better. Just keep trying.

The wire from the Overload contact (Pin 95) will connect to FWD Start button (4), REV Start button(4), FWD N/O (14) & REV N/O (14)
 
erm, you are missing the 110V transformer.

I don't see any power going into the assembly he has set up but I'm assuming all the parts he has are the correct ones and he has the correct voltage.
 
No just following drawings, This is not my just example.

Ok, so just so that I'm clear on this: You are just following the drawing and picture, to see how it works and not actually wiring anything up?
 
the forward and reverse contactors are both identical.
the difference is the power going to
forward contactor is wired L1 L2 L3 from left to right
reverse contactor is wired L3 L2 L1 from left to right
this gives either a clockwise or anticlockwise phase rotation.

it helps if you mark them as fw and rev before you start connecting anything as this will help you identify what you are wiring to.
