To determine

Whether the component is generally normally closed or open when it is used for the function of start.

Expert Solution & Answer

Explanation of Solution

For the component that are used to start are generally normally open as initially they have open contacts and as the component is turned on the contacts get closed and the circuit starts to work.

Consider the Figure 28-2 the start button here is used to start the operation of the circuit and the other start button here is used to start the operation of the circuit. Where the other start button is connected in parallel to the already existing start button. So any one of both the switches can energize the coil M. Thus, the energized coil changes the position of the M contacts of the circuit. The contacts between the line and the load is then closed and the work starts. As the start button is released, the parallel connected auxiliary contacts gets closed and the circuit operation continues.

Thus, the switch is of normally open type.

Using a double-acting cylinder a work piece is removed and tipped onto a conveyor belt. Following are the sequence of operations 1. The operation is to be started using a push button (use the label START PB). Include a stop push button (use the label STOP PB) to stop the process at any time. (Use Memory ON circuit) 2. An acknowledgement signal (S1- Limit switch) is required when the piston is fully extended, to ensure that the work piece has been tipped onto the belt. 3. The extension should be slower than the retraction (use flow control valve) 4. The return stroke should be automatic. a. Design the Electro- Hydraulic Circuit with proper labeling. Include the components required b. Draw the Displacement -step diagram & Displacement -time diagram (include Cylinder, START PB, STOP PB, DCV and S1)
