Up to 10 disturbances can always be stored. If a new disturbance is to be recorded when
the memory is full, the oldest disturbance is over-written by the new one. The nominal
memory capacity for the disturbance recorder is measured with 10 analog and 48 binary
signals recorded, which means that in the case of long recording times, fewer than 10
disturbances are stored. If fewer analog signals are recorded, a longer total recording
time is available. This memory limit does not affect the rest of the disturbance report.

The indications, the fault locator result (when applicable), and the trip values are avail-
able on the local HMI. For a complete disturbance report, front communication with a
PC or remote communication with SMS is required.
