External PID Feedback Supervision Fault

What does 105 mean?

The feedback value for the external PID controller is outside its configured supervision limits (P3.14.4.2 and P3.14.4.3) for a specified delay (P3.14.4.4). This indicates a problem with the external process feedback, potentially leading to unstable control or incorrect process regulation. It signifies a deviation in the external process variable.

Complete Troubleshooting Guide

1. 1

   Investigate the external process and its feedback loop for any anomalies or deviations.

2. 2

   Verify the parameter settings for the external PID controller, especially supervision limits (P3.14.4.2, P3.14.4.3) and delay (P3.14.4.4).

3. 3

   Inspect the external feedback sensor and its connections for proper functioning and calibration.
