• Autotest, for the check on the display and the LEDs.
• Trip Test, for the check on the circuit breaker opening command.
• Test CB, for the check on the controls of the circuit-breaker opening and closing coils
• Zone Selectivity, for the check on Zone Selectivity inputs and outputs.
In the presence of auxiliary power supply and contact type modules, the dedicated sections are enabled:
• Ekip Signalling 4K allows the check of LED and contacts of the module.
• Ekip Signalling 2K-1, 2K-2, 2K-3 allows the check of LED and contacts of the module.
• Ekip Signalling 10K-1, 10K-2, 10K-3 allows LEDs to be checked and contact closing commands to
be sent.
In the presence of an Rc type trip unit and auxiliary power supply, the dedicated test section is enabled:
• Rc Test allows you to check connection and proper operation of the toroid Rc
NOTE: access to the Test Menu requires the insertion of the password.
Using the Ekip T&P and Ekip Bluetooth test accessories it is also possible to check the operation of the
electronic protections from a PC, by simulating various installation conditions.
The sequence includes the following test phases:
Phase Operation
1 Screen with message "www.abb.com"
2 Darkening of the display
3 Color sequence with red, green, blue bands, with gradual increase of backlighting
4 Warning and Alarm LEDs switched on for 1 second
pressing the iTest key for at least 7 seconds.
When the key is pressed, an opening command is sent to the trip coil.
IMPORTANT: the opening command is performed with circuit-breaker closed and
absence of circulating currents.
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 (trip unit, Ekip Com Actuator and opening and closing
coils) is verified through the opening and/or the closing of the circuit-breaker.
