Why must an operator pay particular attention to an auto/manual valve controller when it is placed in manual mode?

🔍 Key Concepts

• Automatic vs manual valve control – how the controller decides when to move the valve • Feedback from system parameters such as pressure, temperature, or level to the controller • What changes in the control loop when you switch from auto to manual

💭 Think About

• Ask yourself: in manual mode, what is the controller looking at when deciding whether to move the valve? Is it still reacting to the process, or only following the operator’s set position? • Consider what could happen to pressure, level, or flow if the valve stays at one fixed position while the system conditions keep changing. • Think about which options describe a change in the logic of control (how the valve responds) versus a change in where you physically operate or observe the valve.

✅ Before You Answer

• Identify which choices talk about the response to system parameters (pressure/level/flow) and which talk only about location of operation or indication. • Check which option would most clearly explain why the operator’s continuous attention becomes critical in manual mode. • Eliminate any choices that confuse local/remote operation with the actual control mode (auto vs manual).

Why must an operator pay particular attention to an auto/manual valve controller when it is placed in manual mode?

Manual valve control is not as stable as automatic valve control.

Valve position will no longer change in response to changes in system parameters.

The position of the valve can only be determined locally during manual control.

The valve can only be operated locally during manual control.
