Note
The "current overshoot" or "current undershoot" monitoring mode is de󹪝ned with the setting
OFF for the upper and lower threshold.
Note
Deactivating monitoring
If the upper and lower threshold values are deactivated (OFF), monitoring will cease for:
• Current overshoot
• Current undershoot
• Blocking current
The following parameters continue to be monitored:
• Fault current (if activated)
• Incorrect phase sequence (if activated)
• Phase failure
The up-to-date measured value is displayed permanently.
The parameters are described in the Chapter "Parameters (Page 281)".
Menu-based operation is described in the Chapter "Menu-based operation (Page 44)".
