Objective

Procedure

The circuit was constructed per the diagram provided. Operation of the double acting cylinder was influenced by both an AND gate and an OR gate. Either push button on the OR gate is designed to start the forward movement of the double-acting cylinder, and the idle stroke is operated by the 3/2 way roller level valve, which is contacted when the cylinder reaches full outward stroke.

Results

After the circuit was built, it was tested. At first, it was not working due to a loose connection, but when it was found and fixed, the circuit worked properly. The system’s cylinder defaulted to a retracted state. When either of the push-buttons of the OR-gate was pressed, the cylinder would extend, and stay after the push-button was released. Then, the cylinder would retract when the push-button for the AND-gate was pressed.
