Comparator 2 Limit Error

What does CP2 mean?

This fault triggers when the monitored value, chosen via H2-26 [Comparator 2 Monitor Selection], is found to be outside the acceptable operating range defined by H2-27 [Comparator 2 Lower Limit] and H2-28 [Comparator 2 Upper Limit]. This indicates a critical process parameter has deviated beyond its safe boundaries, suggesting a potential malfunction or abnormal system state that could lead to operational instability if not corrected.

Complete Troubleshooting Guide

1. 1

   Check the current value of the monitored parameter (H2-26) and verify the configured comparator limits (H2-27, H2-28) to determine which limit was violated.

2. 2

   Investigate the physical process or equipment associated with the monitored value to identify and resolve the root cause of its excursion outside the set limits.

3. 3

   Re-evaluate and adjust the comparator limits if the current settings do not accurately represent the safe operating parameters for the application.

4. 4

   Perform a Fault Reset once the underlying issue causing the monitor value deviation has been addressed and resolved.
