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, 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 90.

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).
For references about the connection and terminals, please consult document 1SDM000091r0001; a cable
of the Class 6 S/FTP type (Class 6 with double screening S/FTP) must be used for the communication bus.
To connect the module to Ekip Touch, please consult document 1SDH001000r0514.

Power supply Ekip Link is supplied directly by the Ekip Supply module to which it is connected.

NOTE: communication between Ekip Touch and the module is interrupted in the absence of
auxiliary power supply

Interface the module has three signaling leds:

LEDs Description
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
Power
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.
Indicates the communication state:
Link (1) • off: incorrect connection, signal absent.
• on steady: connection correct
Indicates the communication state:
Activity (2) • off: no activity on line
• flashing: activity on line present (receiving and/or transmitting)
