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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

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

2. 4

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