LED The LEDs are useful on Ekip Dip in order to distinguish and identify various types of information
on the protection release, 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 release:
• With the release energized (by current sensors or by auxiliary power supply or by Ekip TT
or by Ekip T&P or by Ekip Bluetooth) the LEDs are operational for all the signals.
• With the release de-energized, the LEDs are limited to signalling of the last switch-off or
trip event (combined with the check via iTest, described below).
NOTE: with the release off, the operation of the LEDs is guaranteed if the internal
battery of the release is working properly.
Information
The LEDs combined with the protections provide various information, with 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 49.
The Power LED provides information on the power status of the protection release:
• LED on (default configuration) fixed or blinking, signals release energized.
• LED off signals release de-energized.
NOTE: With the Ekip T&P and Ekip Bluetooth modules and the Ekip Connect software
it is possible to configure how the Power LED functions (LED fixed or blinking).
on the serigraph of the interface.
The values of the protections make reference to the current In, a nominal value of the release
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 release
when resting condition is restored (absence of protection alarms).
specified on the serigraph of the interface.
IMPORTANT:
• Modification of the times must be performed in the absence of protection
alarms.
• Modifications carried out in alarm conditions are accepted by the release
when resting condition is restored (absence of protection alarms).
Settings Two further settings are available:
• Neutral allows the activation and adjustment of the protections on the Neutral channel
• Frequency allows the selection of the installation frequency.
