Which is the display panel for operators?

• A. Human machine interface (HMI)
• B. Hydraulic control unit
• C. Start air valve
• D. Water wash reservoir

Answer: (A)

The display panel for operators is the Human-Machine Interface. The HMI is where operators view real-time process data, alarms, trends, and status indicators, and it often allows input to control the system or adjust setpoints. It centralizes information so you can monitor turbine parameters like temperatures, pressures, RPM, and fault codes at a glance and respond quickly. The other components have different roles: the hydraulic control unit manages the hydraulic actuators that operate valves and other mechanisms; the start air valve supplies the compressed air used to start the turbine; and the water wash reservoir stores the water used for compressor washing. None of these provide a general display interface for operators, which is what the HMI does.
