Q2:
(33 Marks)
Design FBD for manufacturing system where a conveyor belt is used to move a cart through a tunnel for
processing. The process begins when a worker presses a start push button located at the start of the conveyor.
Once the start push button is pressed, the cart moves forward along the conveyor belt and enters the tunnel.
When the cart reaches the end of the tunnel, it stops automatically and remains in place for 10-minutes to
complete a required operation, such as cooling or drying. After the 10-minute delay, the cart automatically
returns to the starting point where the worker is stationed. The system then waits for the worker to press the
start push button again, at which point the process is repeated.
