Function
If the current of one or more phases exceeds threshold I31 and a trip event is present, the protection
transmits the TRIP command after a non-programmable fixed time.
To check and simulate the trip times in relation to all the parameters, please consult:
• summary table of the protections with the operating characteristics (page 95)
• the graph with trip curve (page 102)
Parameter Description Default
Enable
Activates/deactivates the protection and its availability in the
parameters menu.
OFF
ZoneSelectivity
Activates/deactivates the function
NOTE: if at least two of the selectivity S, S2, I, 2I and MCR
are enabled, the input and output are shared with the OR
function; it is sufficient that even a selectivity is activated to
stimulate inputs and outputs

Disabled
Delay ON
Protection activation delay calculated from the presence of the
activation event onwards.
The value is given in seconds and can be set within the range: 0 s
÷ 100 ms, in 0.01 s steps.
NOTE: the protection trips if the event is present for longer
than the set time lag
0 s
Delay OFF
Protection deactivation delay calculated from disappearance of
activation event onwards.
The value is given in seconds and can be set within the range: 0 s
÷ 15 s, in 0.01 s steps.
NOTE: protection deactivates if event is not present for
longer than set delay
15 s
RELT - Ekip signalling 2K-3
If the RELT module is present a dedicated command (RELT Wizard) will be displayed. This will program the
2I protection and other related parameters; for details see page 244.
Commands by remote control
Two further temporary protection activation/deactivation commands are available when the unit is
connected to one or more Ekip Com modules:
• 2I Mode ON: activates the protection.
• 2I Mode OFF: deactivates the protection.
For further details consult the document 1SDH002031A1101
NOTE:
if the protection has been activated by command 2I ON Mode, it is deactivated by
command 2I OFF Mode or when the unit shuts down

When protection 2I is activated, the message “
2I active
” appears in the diagnostic bar and in the Alarm List
page, and the alarm led will be on steady.
