faults are registered if the earth fault detection function is set to “OFF” (Address

= Alarm Only) and an earth fault was already in queue so that the trip delay (T
Sens.E/F
) could expire.
Up to 200 earth fault messages can be stored for the last 8 earth faults.
All available indications are displayed and explained in Appendix B. In a specific case,
