IMPORTANT:
• The coil opening and closing commands work only with the trip unit powered by
auxiliary power supply.
• Make sure that the coils are connected to the power supply source.
• The commands verify the operation of the trip unit: any possible faults on Ekip COM
Actuator or the coils are not found by the test.
Protection.
The following are available for each command:
• Input, to check the state of the Zone Selectivity input.
• Force output, in order to force the state of the Zone Selectivity output to high.
• Force Output, to trip unit the override on the Zone Selectivity output.
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.
to send the command Autotest.
The command activates an automatic sequence of test for the LEDs and contacts:
Phase Operation
1 Reset LEDs and output contacts
Switch-on in sequence of all LEDs and closing in sequence of all the associated output
2
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 autotest sequence involves the closing of the output contacts: the
check on the correct closing is the user's responsibility.
to the toroid to check correct operation.
NOTE: the test is available only with the toroid correctly connected, the trip unit in Rc
configuration, auxiliary power supply present.
Protection test
To perform the protection command test, follow this procedure:
Phase Operation
1 Make sure that the circuit-breaker is closed and that there are no currents circulating
2 Connect Ekip T&P or Ekip Bluetooth
3 Start the communication with Ekip Connect
4 Open the Information page and select the Test command, which opens the protection test page
5 Set up the test as required and verify that the trip unit functions properly
