Input Pressure Supervision Fault

What does 109 mean?

The input pressure supervision signal (P3.13.9.2) has dropped below either the alarm limit (ID 1109) or the fault limit (ID 1409), indicating an issue with the system's input pressure. This could affect pump or process operation, potentially leading to cavitation, poor performance, or system shutdown.
