SME2-IS - Manual - 06 - 2021
FUNCTIONAL CHARACTERISTICS
Extended conguration
In the EXTENDED conguration, the SME2-IS connects directly to the router/UP and to the DY 800.
When a fault occurs, the SME2-IS transmits the information to the router/UP, which starts the auto-
mation function.
The automations on the router/UP send a series of IEC 61850 messages to the SME2-IS, to handle the
operation of the DY 800 and run the reclosing cycle if necessary.
The interface mode can be selected by setting the parameter Device conguration, in the Set\
Base menu.
Regardless of the conguration, one can also select the type of operation from the following options:
1. FSL1: BLIND wait always active
2. FSL2: BLIND wait for rst fault occurrence only
3. FRT
The automation mode can be selected by setting the parameter Selected automation function
in the menu Set \ Base.
