When pressing either of the two pushbuttons in a control system, what is the expected action?

In a control system utilizing pushbuttons, the expected action when either pushbutton is pressed typically involves advancing the piston rod of the cylinder. This is a common operation in systems where pushbuttons are designed to activate a movement or process. The pressing of the pushbutton sends a signal to the control mechanism, which actuates the cylinder, allowing the piston rod to extend and perform its intended function.

Advancing the piston rod indicates that the system is engaging in active operation, which is a fundamental aspect of many automation and control applications. This action is consistent with the design of such systems, where user inputs are meant to initiate work cycles or tasks.

Other options, such as retracting the piston rod or placing the system in standby mode, would not typically occur with a simple pushbutton press, as these actions usually require different controls or conditions to be met. Similarly, resetting the system often involves a more specific mechanism than merely pressing a typical operational pushbutton.
