3 - Test

Presentation The Ekip TT and Ekip T&P modules connected to the Ekip Dip allow you to perform various tests:
• Trip unit LED test
• Check on the presence of the internal battery
• Circuit-breaker opening test (trip test)
• Protection test.

LED test The LED test can be performed directly on Ekip Dip:
Phase Operation
1 Connect a module to the front test connector of frontal test.
2 Press the iTest pushbutton for at least 6 seconds, but less than 9 seconds.
3 When the protection LEDs light up, trip unit the iTest pushbutton.
Check the following switch-on sequence:
• S, I, G LEDs on fixed
4
• Led pre-alarm L and alarm L that alternate three times
• All the protection LEDs off

Battery test The battery check is integrated in the LED test procedure, except for the battery error signal:
• If the battery is absent or not working, after iTest is pressed the error is signalled by five flashes of the
pre-alarm LED L.
• If the battery is present and working, the LED test proceeds as in the normal procedure.

Protection test In order to perform the protection test, follow the instructions below:
Phase Operation
1 Make sure that the circuit-breaker is closed and that there are no primary currents.
2 Connect Ekip T&P to the front test connector.
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.

Opening test The opening test can be performed directly on the trip unit or from Ekip Connect.
To perform the test:
Phase Operation
1 Make sure that the circuit-breaker is closed and that there are no primary currents.
2 Connect a module to the front test connector of frontal test.
3 Press the iTest pushbutton for at least 9 seconds.
4 Check that the circuit-breaker opens and that the TU Reset button comes out

To perform the test from Ekip Connect:
Phase Operation
1 Make sure that the circuit-breaker is closed and that there are no primary currents.
2 Connect Ekip T&P to the front test connector.
3 Start the communication with Ekip Connect.
4 Select the trip test command.
5 Check that the circuit-breaker opens and that the TU Reset button comes out
