Star delta program making is very easy in Delta PLC. When the start push button is pushed then the main contractor and the star contractor must go ON and at the same time timer should start and after the timer has completed the pre-set time the Star contractor should be off and the delta contractor should become on. It should be noted that the main contractor should always be on.
