HMI: Settings/Opening and Settings/Closing
An alarm can be set against both the number of opening and closing operations if they
exceed a set threshold. The threshold is set here.

52a/52b contacts status
The 52a/52b auxiliary contacts are proximity switches that are there to reflect a direct
image of the circuit breaker position and indicate the status of the circuit breaker:
• 52a aux. contact:
• 52b aux. contact:
HMI: Measurements/Sensors
If for any one pole, the 52a and 52b contacts have the same value (like in example above)
for longer than the "pole discrepancy timeout" set, then a "Pole discrepancy" alarm is
raised. It alerts to the fact that there is a problem with the 52a and 52b contacts for one
pole and that the position of the CB for that pole might be incorrect.
