From the display it is possible to access the test area, where commands are available to check
certain functions of the Trip unit. Below are the details of all the commands available in the Test
menu (page 30).
Ekip T&P with Ekip Connect has a Protection test section to simulate the presence of current
signals or alarm voltages and verify times and reactions.
The Self-test command starts an automatic sequence of switching on the display and the LEDs
to allow verification of their operation.
The sequence includes the following test phases:
1. Screen with the text "www.abb.com"
2. Gradual fade of the writing on the display.
3. Lighting of the Warning and Alarm LEDs for one second.
Selecting the Trip test command opens a page that asks for confirmation to run the test operation
by pressing the iTEST button.
Once the button is released, an opening command is sent to the CB Trip coil.
IMPORTANT:
the opening command is sent with the circuit breaker closed and no current
flowing
following a command, the verification of the effective change of the actuator
status and of the information on the display are delegated to the user: make
sure that no alarms are noted on the diagnostic bar before performing the test
NOTE: to reset the TRIP signal press the iTEST button or send a TRIP RESET
command (via Ekip Connect or remotely)
Selecting the CB Test command opens a submenu with the commands Open CB and Close CB.
The commands activate the YO opening coils and YC closing coils respectively. The correct
transmission of the command is confirmed by the window with the word "Test Executed."
The correct operation of the entire control system (Trip unit and opening and closing coils) is
verified by opening and/or closing the circuit breaker.
IMPORTANT: coil opening and closing commands work only with the Trip unit switched
on by an auxiliary power supply.
Make sure the coils are connected to the power source
The commands check the Trip unit's operation. Any malfunctions of the coils
are not detected by the test
