Configuration The Circuit breaker-Configuration menu, allowing the presence of the External neutral sensor to be activated,
is available for the 3P CB (page 188).
Activation of the configuration with
External neutral (3P + N) enables:
• histograms of phase Ne in the Histograms page
• neutral current measurements
• submenu for configuring the Neutral protection (
Neutral Protection )
• neutral current recording in the case of TRIP
With 3P CB, the parameter is set by default as: 3P.
Ground protection
In the earth Circuit-breaker-Protections menu of the LSIG version of Ekip Touch you can:
• activate/deactivate the presence of external toroid S.G.R and relative Gext protection (page 187, 79).
• activate the presence of Rc Toroid and relative protection (page 187, 82).
• activate/deactivate the MDGF transformer presence and relative MDGF protection.
NOTE: Rc Toroid can be activated if the Measuring Measurements package and Rc version
Rating plug are present; Toroid presence in the menu can only be deactivated afterwards
by replacing the installed Rating plug
With Ekip Touch LSIG, the parameter is set by default as: Absent.
Line frequency Frequency adjustment is performed to set the installation frequency; the choice is between 50 Hz and 60 Hz.
NOTE: the measurements are taken on the basis of the set grid frequency: incorrect configuration
of the parameter may lead to abnormal measurements and protection
Ekip Touch is supplied with the parameter setting that suits the ordered configuration.
Modules
The Modules menu provides various options:
Parameter Description Default
Local/Remote
The parameter defines the mode in which the parameters are written
in the unit:
•
Local : parameter editing only via the display or service connector
•
Remote
: parameter editing only remotely (Ekip Com modules)
NOTES
:
• the Remote mode requires the presence of auxiliary
power supply and Ekip Com modules, otherwise it disables
automatically
•
However, the Local/Remote parameter can still be edited in
the Remote mode
Local
Local bus
The parameter enables communication between the Trip unit and
modules installed via terminal box or outside the unit to be activated.
Correct communication between unit and modules is confirmed by:
• population of the
Modules menu with all the modules connected
• Power Leds of the modules on and synchronized like the power led
of Ekip Touch
• absence of Local Bus alarm in the diagnosis bar
