MACHINE CONTROLLER

Controller function

To design the controller we must know the motions and actions of

press well to determine the input and output needed in controller and

write the suitable program to do this motions and actions

The motions and actions required

When press on down switch press will stop the motion in up

direction and move downwards

When press on up switch the press will stop the motion in

down direction and move upwards

When stop switch was pressed stop any motion

When the press touch the upper limit switch stop motion in

upward direction

When the press touch the lower limit switch stop motion in

downwards direction and move upward

Green Led Indicator Light on when power switch is on and off

when the Emergency Stop Switch is Pressed

Red led indicator light on when Emergency stop Switch is

Pressed

Yellow Led Indicator light on when the press move downward

According to the required motions and actions we designe and

programing the circuit whiche achive the required functions
