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
or by Ekip Bluetooth) 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
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 and Ekip Bluetooth modules and Ekip Connect software, it is possible
to configure how the power LED functions (LED fixed or blinking).
Protections: thresholds
The thresholds of all the protections can be modified with various dip-switches, as specified on the serigraph
of the interface.
The values of the protections make reference to the current In, a nominal value of the trip unit 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).
Protections: times
The times and the curves of the protections can be modified with various dip-switches, as 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 trip unit when resting
condition is restored (absence of protection alarms).
Settings
Two further settings are available:
•
Neutral
allows activation and adjustment of the protections on the neutral pole.
•
Frequency
allows the selection of the installation frequency.
