Is it true that the LS can inadvertently slew when PDU Motor Control unit AC is set to ON even if in local with key removed?

Is it true that the LS can inadvertently slew when PDU Motor Control unit AC is set to ON even if in local with key removed?

• A. True
• B. False
• C. Only under specific conditions
• D. Only if the system is rebooted

Answer: (A)

The correct response indicates that it is true that the LS (Launch System) can inadvertently slew when the PDU (Power Distribution Unit) Motor Control unit AC is set to ON, even if the system is in local mode with the key removed. This condition suggests that the power to the motor control unit remains active, allowing potential unintended movement of the launch system regardless of the control mode being set to local or the key being removed. This emphasizes the importance of procedure adherence and safety precautions when managing the system's power controls, particularly in avoiding risks associated with inadvertent slew movements. Such unintended actions could occur due to electrical feedback or other factors that allow commands to bypass local safeguards. Understanding this feature informs operators of necessary precautions to prevent accidents during maintenance or when conducting operations.
