Zone selectivity With the Zone Selecitivity function:
• the IP addresses entered refer to actors with the role of interlock with respect to the current role
• the protections for which selectivity must be actuated by setting a mask, must be selected for each interlock
actor entered. Thus set, the function will now be indicated as logic in the following text so as to distinguish
it from the standard function, now also indicated as hardware in the following text
• thus selected, the protections add to those of the hardware S, I, 2I, MCR, G, D-Backward and D-Forward
• hardware selectivity only, or both hardware and logic selectivity can be selected
• diagnosis can be set, for each interlock release, to ascertain whether there is consistency between the
hardware and logic selectivity information
• a mask can be set for the purpose of identifying those protections whose received selectivity information
must be re-transmitted, regardless of whether the actor is in the alarm status. The mask is only applicable
to logic selectivity information
For further details about the Zone Selectivity function with Ekip Link , please consult page 85.
Connections The module must be assembled in the first vacant slot of the terminal box after Ekip Supply , either on the
circuit-breaker (fixed version) or on the fixed part (withdrawable version).

LEDs Description
Power
Signals the on status and correct communication with Ekip Touch:
• off: module off
• on steady or flashing synchronized with the Power led of Ekip Touch: module on
and communication with Trip unit present.
• flashing not synchronized with the Power led of Ekip Touch (2 fast flashes per
second): module on and communication with Trip unit absent.
Link ( 1 )
Indicates the communication state:
• off: incorrect connection, signal absent.
• on steady: connection correct
Activity ( 2 )
