  1. What are your key responsibilities as a Central Control Room Operator?

    • Answer: My key responsibilities include monitoring and controlling critical systems, responding to alarms and alerts, troubleshooting issues, coordinating with other teams, maintaining detailed logs, ensuring the safety and security of the facility, and adhering to strict operational procedures.

  2. Describe your experience with SCADA systems.

    • Answer: I have [Number] years of experience working with SCADA systems, including [Specific SCADA systems used, e.g., Wonderware, Ignition, etc.]. My experience encompasses monitoring and controlling processes through the SCADA interface, configuring alarms, generating reports, and troubleshooting system issues.

  3. How familiar are you with different types of sensors and actuators?

    • Answer: I am familiar with various sensor types, including temperature sensors (thermocouples, RTDs), pressure sensors, flow sensors, level sensors, and gas detectors. I also understand the functionality of different actuators, such as valves, pumps, and motors, and how they interact with the controlled system.

  4. Explain your understanding of process control loops.

    • Answer: I understand that process control loops use feedback mechanisms to maintain a process variable at a desired setpoint. This involves sensors measuring the process variable, a controller comparing the measured value to the setpoint and adjusting the output to an actuator, which then changes the process variable. I am familiar with PID controllers and their tuning parameters.

  5. How do you handle multiple alarms simultaneously?
