Data Storage

The relay stores 2 types of data: Fault records, event records.
Data records are stored in the non-volatile memory. The Data Storage menu contains the settings for clearing
events and faults.
Fault Records (Trip Log)
The fault records are generated when the protection function detects a fault condition and the trip alert
message appears on the LCD. Up to 10 fault records can be stored and displayed on the fascia LCD.
The fault record provides a summary of the following relay status:
•
Settings group
•
Element that issued the trip
•
Any phase/earth picked up
•
Fault magnitude
•
LED indications
•
General alarm
•
Date and time
The trip alert message is displayed until you acknowledge the fault.
The fault and event records provide the full sequence of events that results to a trip for analysis.
The 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 in HMI
Event Records (Event Log)
The event recorder feature allows the time tagging of any status change (Event) in the relay. When an event
occurs, the actual event condition is logged as a record with a date and time stamp to a resolution of 1 ms.
The relay can store a maximum of 100 event records. When the operational log is full, any new record over-
writes the old records.
Stored events can be cleared by using the DATA STORAGE > Clear Events setting in HMI or from Reydisp
Evolution.
The following events are logged:
•
Status change of binary outputs
•
Status change of binary inputs
•
Change of settings
•
Device startup and shut down
•
Protection element operation
•
Critical or low battery
•
General alarm
•
Internal Relay Failure (IRF)
The Thermal level of the device can be cleared using the DATA STORAGE > Reset Thermal Level setting
in HMI or from Reydisp Evolution.
