Protections: Thresholds; Protections: Times; Settings; Itest Pushbutton - ABB SACE Emax E1.2 Operating Instructions For The Design Engineer

Protections: thresholds The thresholds of all the protections can be modified with various dip-switches, as specified on the serigraph
Protections: times The times and the curves of the protections can be modified with various dip-switches, as specified on the
Settings Two further settings are available:
iTest pushbutton The iTest pushbutton is useful for three operations:
Test connector The test connector allows the connection of Ekip TT, Ekip T&P and Ekip Bluetooth modules, in order to

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 29.
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).
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).
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).
• Neutral allows activation and adjustment of the protections on the neutral pole.
• Frequency allows the selection of the installation frequency.
• 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.
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).
