The trigger signal(s) and the edge are selected with SPA parameters V236...V237

and V241...V242; see Table 5.1.17.-5 and Table 5.1.17.-6. The recorder can also be

triggered manually with SPA parameter M1.

Triggering of the disturbance recorder is only possible if the recorder is not already

triggered.

5.1.11.5. Settings and unloading

The setting parameters for the disturbance recorder are V parameters V236...V238,

V240...V243 and V246, and M parameters M15, M18, M20 and M80...M83.

Unloading correct information from the recorder requires that M80 and M83 have

been set. Unloading is done by using a PC application. The uploaded recorder data

is stored in separate files defined by the comtrade® format.

5.1.11.6. Event code of the disturbance recorder

The disturbance recorder generates an event code on triggering (E31) and clearing

(E32) the recorder. The event mask is determined using SPA parameter V155.

5.1.12. Recorded data of the last events

The relay records up to five events. This enables the user to analyze the last five

fault conditions in the electrical power network. Each event includes the measured

voltages, start durations and time stamp, for instance. Additionally, information on

the number of starts of the stages and trips is provided.

Recorded data is non-volatile by default, provided that the battery has been inserted

and is charged. A master reset, that is, clearing of indications and memorized values

and unlatching of output contacts, erases the contents of the stored events and the

number of starts of the stages.
