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.

Complete Troubleshooting Guide

1. 1

   Check the process to identify any reasons for low input pressure, such as blockages, leaks, or pump issues.

2. 2

   Review the parameters in menu M3.13.9, specifically the alarm and fault limits, to ensure they are set appropriately.

3. 3

   Inspect the input pressure sensor and its connections for proper functioning, calibration, and wiring.
