What role does the phase detector light play in the SENTINEL system?

The phase detector light in the SENTINEL system serves a critical role in ensuring the accuracy and functionality of the system’s operations. When the phase detector light indicates generator phase correctness, it confirms that the generator is operating within the required phase parameters. Achieving proper phase alignment is essential for the SENTINEL system to process information accurately and effectively manage air defense scenarios. If the phases are not aligned, it could lead to errors in system performance, potentially compromising mission effectiveness. The illumination of the phase detector light serves as a visual cue for operators, allowing them to quickly assess whether the system is in a suitable state for operation.
