In LPA 125 mode, when does the system load?

In the context of LPA (Low Pressure Alert) systems, the operation of loading is critical for maintaining system functionality and pressure stability. The correct choice indicates that the system is designed to initiate loading when the system pressure falls to 115 psig.

This value is specifically chosen because it serves as a threshold that allows for the timely activation of the loading mechanism. By setting the threshold at this pressure, the system can respond promptly to drops in pressure without allowing the system to reach too low a level, which could cause operational issues or insufficient pressure for proper function.

The choice of 115 psig as the activation point reflects a balance between efficient operation and the need to avoid excessive pressure drops that could lead to system instability. Maintaining pressure within specified ranges is essential for ensuring the reliability and safety of the engineering systems involved.
