LEDs The LEDs are useful on Ekip Dip in order to distinguish and identify various types of information on the
protection trip unit, the circuit-breaker and state of the line currents.
Operational conditions
The operation of the LED is determined by the power supply conditions of the trip unit:
• With the trip unit energized (by current sensors or by auxiliary power supply or by Ekip TT or by
Ekip T&P) the LEDs are operational for all the signals.
• With the trip unit de-energized, the LEDs are limited to the signalling of the last switch-off or trip
event (combined with the check via iTest, described below).
NOTE: with the trip unit off, the operation of the LEDs is guaranteed if the internal battery
of the trip unit is working properly.
About
The LEDs combined with the protections provide various information, through different combinations of
lighting and blinking.
NOTE: all the combinations related to protection LED signals are described in chapter Self-
diagnosis and signalling , on page 42.
The power-on LED provides information about the power status of the protection trip unit:
• LED on (default configuration) fixed or blinking, signals trip unit energized.
• LED off signals trip unit de-energized.
NOTE: with Ekip T&P module and Ekip Connect software, it is possible to configure how the
power LED functions (LED fixed or blinking).
serigraph of the interface.
The values of the protections make reference to the current In, a nominal value defined by the Rating Plug.
IMPORTANT:
• Modification of the thresholds must be performed in the absence of protection alarms.
• Modifications carried out in alarm conditions are accepted by the trip unit when resting
condition is restored (absence of protection alarms).

IMPORTANT:
• Modification of the times must be performed in the absence of protection alarms.
• Modifications carried out in alarm conditions are accepted by the trip unit when resting
condition is restored (absence of protection alarms).
• Neutral allows activation and adjustment of the protections on the neutral pole.
• Frequency allows the selection of the installation frequency.
