• Reset the signal of the tripped protection. This operation can be performed when the circuit-breaker
is both open and closed and with currents present, by pressing the push-button for about 1 second
(the signal disappears when the push-button is released).
• With the trip unit off, check the information relating to the switch-off or tripping event.
NOTE: with the trip unit off, pressing of the iTest button switches on (for approximately 4
seconds):
• the power-on LED, if the trip unit is off due to an energy drop (primary current less than the
minimum level of operation, removal of auxiliary power supply with circuit-breaker open,
etc...).
• the protection tripped LED if the trip unit is off due to a protection trip.
following operations:
• Temporary energizing of the trip unit to check the status, and perform the trip test (option possible
with all the front interface modules).
• Analysis, supervision and setting of additional parameters through external communication test
units (Ekip T&P).
