The VARTOMS Mode Selector is located on which panel?

• A. Main switch panel
• B. Overhead panel
• C. Left side panel
• D. Bottom instrument panel

Answer: (A)

The function of the VARTOMS Mode Selector is to choose the operating mode for the VARTOMS system, and it belongs on the main switch panel because that panel houses the primary controls that directly affect plant operation. Placing the mode selector there gives the operator quick, central access during startup, changes in load, or abnormal conditions, reducing the time and effort needed to reach the control. The main switch panel is designed for critical, high-impact controls, so keeping the mode selector there supports fast, coordinated action. Overhead panels are mainly for alarms and indicators or nonessential controls, which makes them less suitable for a mode selector that you want to access rapidly. Left side and bottom instrument panels are more about auxiliary controls or detailed instrumentation rather than central operational controls, so they don’t fit as well for this function.
