Hi,

The existing devices 7SJ624 has set undervoltage protection which I'd like to disable by CFC logic (CB extracted & Test Position) in order to be able to operate the CB in test position, but whatever I've tried was unsuccessful with message ˝fault active˝. Is there any way to do it without applying the voltage on the protection terminals?

Thanks,

First thanks for the answer. I've found ˝Current Supervision˝, it's in over/under voltage tab, Display additional settings, but I'm not sure I'll be able to upload it to the relay due to the same issue ˝Fault is active˝. However I'm going to try.

Finally solved. Undervoltage protection can be blocked via ''Menu-Control-Tagging-Set-(U<, U> blk>ON)'' on the protection itself.
