  2. 2. 2- Turning an IM ON and OFF from two places A 3 ph motor can to be turned ON from two places using one of the push buttons S3 or S4 and be turned OFF using either PB S1 or S2. Design a program to accomplish this task.
  3. 3. 3- Reversing the direction of rotation of IM with stopping Direction of rotation of a 3 ph motor can to be reversed by pressing one of the pushbuttons S2 or S3 provided that the stopping PB S1 is pressed first. Design a program to accomplish this task.
  4. 4. 4- Reversing the direction of rotation of IM without stopping Direction of rotation of a 3 ph motor can to be reversed by pressing one of the pushbuttons S2 or S3 without needing to press the stopping PB S1 first. Design a program to accomplish this task.
