3.6 Data Storage
Parameter: Energy Storage > Reactive Imp Energy Unit
•
Default Setting:
The energy increments define the resolution of the stored energy values reported by instruments and
communications protocols.
When the accumulated energy quantities reach a set increment, the relay issues a pulse to the binary
outputs i.e. Reactive Imp Pulse, (see
The direction of energy transfer is described in section

Event Log

3.6.5
The event recorder feature allows the time tagging of any change of state (Event) in the relay. As an event
occurs, the actual event condition is logged as a record along with a time and date stamp to a resolution of 1
millisecond. There is capacity for a maximum of 5000 event records that can be stored in the relay and when
the event buffer is full any new record will over-write the oldest.
The following events are logged:
•
Change of state of binary outputs
•
Change of state of binary inputs
•
Change of settings and settings group
•
Change of state of relay functions
The information available in the event log is defined in the Reydisp configuration tool. All logged data includes
date, time and its state.
Events are available over data comms channels. Filtered events are available from the relay fascia.

Default Setting:
This is used to delete all stored event records.
The faults can also be deleted from a communication command.
