7SR224 Argus Description of Operation
6.4.4 Fault Records
Up to ten fault records can be stored and displayed on the Fascia LCD.
Fault records provide a summary of the relay status at the time of trip, i.e. the element that issued the trip, any
elements that were picked up, the fault type, LED indications, date and time. The Max Fault Rec. Time setting
sets the time period from fault trigger during which the operation of any LEDs is recorded.
When examined together the event records and the fault records will detail the full sequence of events leading to
a trip.
Fault records are stored in a rolling buffer, with the oldest faults overwritten. The fault storage can be cleared with
the DATA STORAGE>Clear Faults setting or using Reydisp Evolution via Relay > Data Records > Reset Data
Log Record.
6.4.5 Data Log
The Data log feature can be used to build trend and maximum/minimum demand records. Up to 10,080 individual
time stamped records of each phase current and voltage (where fitted) analogue signal are recorded and stored
at a user defined rate e.g. 7 days @ 1 minute intervals and > 1 year @ 1 hour intervals.
6.5 Metering
The metering feature provides real-time data available from the relay fascia in the ‘Instruments Mode’ or via the
data communications interface.
