Basic Lift Circuit (Four floors)

This is basic lift circuit. when press P1 push button lift starts to work 1st floor to 2 nd floor. Then after time duration it is automatically reach to 3 rd floor. And samething happen in 3rd floor & 4 th floor.

We can do it mannually also by using P2 , P3 , P4 , P5 , P6 .
P2 -:4 - 3 floor
P3 -: 3 - 4 floor
P4 -: 2 - 3 floor
P5 -: 3 - 2 floor
P6 -: 2 - 1 floor

Modified Forward Reverse circuit

Difference in this circuit compare to Forward Reverse circit N/O push button used for Stop. PFR & overload are used for safety. Operation of the circuit as same as the Forward Reverse circit.

Forward Reverse circuit

 In this circuit when we push N/O start f push button motor stars to run Forward Direction.                       

When we want to run motor in reverse direction 1st push N/C push button & then push N/O starts R push button. To stop the circuit, push N/C push button.                                                  

Direct Circuit

In this circuit when we push N/O start 1 push button motor 1 starts to run.

When we want to run motor 2 we can do that pushing N/O start 2 push

button. When we want to stop the circuit motor 1 running or either motor 2

we can do that pushing N/C push button.

In this Circuit

When we push N/O start 1 push button first three phase motor 1 starts to Run.

When want to run 2nd motor have to push N/C push button & then have to

press N/O push botton 2  to run 2nd motor.
