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.
iTest pushbutton
The iTest pushbutton is useful for three operations:
• Perform tests (circuit-breaker opening test and LED test).
• Reset the signal for intervention of the protection as a result of a trip.
• 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.
Test connector
The test connector allows the connection of Ekip TT, Ekip T&P and Ekip Bluetooth modules, in order to
perform the 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, Ekip Bluetooth).
