77Unloading correct information from the recorder requires that M80 and M83 havebeen set. Unloading is done by using a PC application. The uploaded recorder datais stored in separate files defined by the comtrade® format.5.1.11.6. Event code of the disturbance recorderThe 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 eventsThe relay records up to five events. This enables the user to analyze the last fivefault conditions in the electrical power network. Each event includes the measuredcurrents, start durations and time stamp, for instance. Additionally, information onthe number of starts of the stages, trips and auto-reclose shots is provided.Recorded data is non-volatile by default, provided that the battery has been insertedand is charged. A master reset, that is, clearing of indications and memorized valuesand unlatching of output contacts, erases the contents of the stored events and thenumber of starts of the stages.The number of trips and auto-reclose shots is stored in the non-volatilememory (EEPROM) and is thereby not cleared when performing amaster reset. The number of trips can be erased by entering the value 1and the number of auto-reclose shots by entering the value 2 intoparameter V166.The relay collects data during fault conditions. When all start or thermal alarmsignals have been reset or a stage trips, the collected data and time stamp is stored asEVENT1 and the previously stored events move one step forward. When a sixthevent is stored, the oldest event is cleared.Feeder Protection RelayTechnical Reference ManualREF 610REF 6101MRS755310
