Protections - ABB SACE Tmax XT2 User Manual

Protections

Principle of The protection functions are available with all models and versions of Ekip Touch.
Operation
Each protection is combined with a different signal (currents, voltages, frequencies, powers, etc.)
but the operating principle is common:
With the Ekip CI module, Ekip M Touch allows selecting a different TRIP configuration so that, if
TRIP
tripped, a contact of the Ekip CI module connected to an external contactor (Normal mode) is
triggered.
For more details see the Ekip M Touch parameters (page 66)
Many protection thresholds are shown on the display in two different sizes: the absolute and

relative values.
The relative value depends on the type of measurement:

Protection The protections listed in the following chapters are grouped by packages, whose availability
packages depends on the Trip unit model and version and possible installation as an additional package:

1. If the measured signal exceeds the threshold set, the specific protection activates (pre-
alarm and/or alarm condition).
2. The alarm is shown on the display, and, based on the protection parameters set, after a
time interval (timing) it can be converted into an opening command (TRIP) to the CB's
internal Trip coil.
NOTES:

If the measured signal falls below the threshold set before the tripping time has
elapsed, Ekip Touch exits the alarm and/or timing state and returns to normal
operating condition

All the protections have a default configuration: check the parameters and change
them as needed for installation before startup
NOTE: for I and G protections, the TRIP is always managed with a Trip Coil command
