Putting a controller on manual control implies what action by the operator?

When a controller is put into manual control, it implies that the operator takes direct responsibility for managing the final control element of the process. In this mode, the automatic feedback loop, which typically adjusts the output based on changes in the process variable, is disabled. Instead, the operator can adjust the output as they see fit, directly influencing how the system operates.

The operator has the authority to make deliberate adjustments without relying on the automated calculations that would typically regulate the process based on sensor data. This manual intervention allows them to respond to unique situations or requirements that may not be effectively handled by automatic controls. Therefore, the focus is on the operator's direct control over the operational parameters of the system, reinforcing the idea that putting a controller in manual mode signifies a hands-on approach to managing the system output.
