7.1.1.4 Ground Fault Messages (Ground Fault messages associated with the sensitive ground fault
function)
For devices with sensitive ground fault detection, special ground fault records are
available. Messages are provided if the protection is set for “$ODUP2QO\” in Address
3101, and the ground fault remains long enough for the time delay to expire.
Up to 15 messages can be recorded for the last 3 faults.
All available messages are displayed in table form and explained in the Appendix. In
a specific case, only the applicable messages appear on the display.

If no messages are present for a fault record, then access is denied and the message

The messages within a ground fault record are listed in chronological order and num-
bered, from the oldest to the newest.
The inception of a ground fault is identified with the date (without year) and the time in
hours, minutes, and seconds (resolution to ms). See the example in Figure 7-9.
