The direction of energy transfer is described in section 3.2 Device Configuration .
Energy Storage Settings
Parameter: Energy Storage > Active Exp 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. Active Exp Pulse, (see 3.5 Binary Outputs ).
The direction of energy transfer is described in section 3.2 Device Configuration .

NOTE
Changing this parameter from the fascia will cause the device to restart to allow IEC 61850 to update.
