Presentation
The Ekip TT, Ekip T&P and Ekip Bluetooth modules connected to the Ekip Dip trip unit 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

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.
