IMPORTANT: the zone selectivity commands work with:
• Auxiliary power supply present.
• Circuit-breaker open and, in the case of the withdrawable version, in
connected or test position.
Zone Selectivity
IMPORTANT:
• The coil opening and closing commands work only with the release
powered by auxiliary power supply.
• Make sure that the coils are connected to the power supply source.
• The commands verify the operation of the release: eventual faults on Ekip
COM Actuator or the coils are not found by the test.
Test CB
Selecting the command Test CB opens a submenu containing the commands Open CB and
Close CB.
The commands allow you to activate coil opening and closing respectively: the correct sending
of the command is confirmed by a window with the message "Test Executed".
The correct operation of the entire command system (release, Ekip COM Actuator and opening
and closing coils) is verified with the opening and/or the closing of the circuit-breaker.
NOTE:
• The command Open CB is sent in the presence of a closed or open circuit breaker.
• The Close CB is activated in the presence of an open circuit-breaker.
The command Zone Selectivity allows you to select the line you want to check: Protection
S or Protection G.
The following are available for each command:
• Input, to check the state of the zone selectivity input.
• Output force, to force the state of the zone selectivity output high.
• Release Output, to release the override on the zone selectivity output.
Ekip Signalling
The submenus for testing the Ekip Signalling modules in the various versions 4K, 2K-1, 2K-2,
2K-3, 10K-1, 10K-2, 10K-3 allow you to send the command of Self-test.
The command activates an automatic sequence of test LED and contacts:
Phase Operation
1 Reset LED and output contacts .
Switch-on in sequence of all LEDs and the closing in sequence of all the
2
associated output contacts
3 Reset initial conditions
NOTE: with Ekip Signalling modules 2K-1, 2K-2, 2K-3, the sequence includes testing
of the LEDs of the inputs.
IMPORTANT: the self-test sequence involves the sending of the close command
of the output contacts: the check on the correct closing is the user's
responsibility.
