Correlated measurements
The type of protection involved determines the measurements recorded at the moment of tripping:
Protection
against
Measurements recorded at the moment of the tripping
Current
Phase currents L1, L2, L3, Ne, Ig, Ige, Irc.
NOTE:
• Ne is available with four-pole or three-pole circuit brakers with external Neutral
• Ig is available with a trip unit in the LSIG version, in the case of trip due G
protection.
• Ige is available with a trip unit with a SGR toroid, in the case of trip due Gext
protection.
• Irc is available with a trip unit with a Rc toroid.
Temperature
Phase currents L1, L2, L3, Ne.
NOTE:
the temperature cannot be viewed from the display.
Access to the last trip
The information on the most recent opening, as well as in the Historicals menu, is accessible in three
different ways, according to the conditions of the trip unit:
Condition Access mode
1) Opening just happened.
2) Trip unit with auxiliary power supply
(always on).
The main page is temporarily replaced by the information page
on the opening just occurred.
The page is available until the reset of the trip unit (through the
iTest key).
1) Opening just happened.
2) Trip unit without auxiliary power supply
or Ekip Measuring Pro connected (off
with circuit-breaker open).
Pressing the iTest key displays (for few seconds) the
information page on the last trip.
1) Fast reading with trip unit on
From any page that is not a menu or a page opened from a
menu, press the iTest button four times.

Description
The trip unit can record the last 200 events, referring mainly to variations in state and operation.
Specifically, the recorded events can supply information on:
• Trip unit: configuration status of the bus, operating mode, active set, auxiliary power supply.
• Protections: delay in action or alarm.
• Connection states and connection alarms: circuit-breaker, current sensors, trip coil, Rating Plug.
• Tripping: state of the opening command, or signal of tripping due to protection.
NOTE: in the list of the events, the first available is the most recent one. If the trip unit has
exceeded the threshold of 200 events, the oldest ones are progressively overwritten.
