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
• 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.
