Date of installation
Installation date of the circuit-breaker.
Load Profile Timers
SACE Emax 2 has 4 counters which display how long the maximum current measured has remained in each
percentage band.
The counters are expressed in seconds and the bands are: 0-49%In, 50-79%In, 80-89%In, >90%In.
Energy Store Time
The counter indicates the time that has elapsed since the last energy metering reset.
It is active and updated in the presence of at least one of the following: auxiliary supply, supply by Ekip T&P
or supply by Ekip Measuring.
Led Alive
The parameter allows the behaviour of the power-on LED indicator of the trip unit and of all modules that can
be connected to Ekip Supply to be changed. If activated:
• Trip unit: it comes on at a frequency of 0.5 Hz.
• Modules connected to Ekip Supply: if there are no communication errors, they synchronize with the flashes
of the trip unit LED.
If deactivated, the power-on leds on the respective devices come on with a steady light.
Open/Close Remote Direct
Command
The parameter controls two different command packages for remote circuit-breaker opening and closing:
•
Enabled
: commands 7 and 8 are valid (direct commands for
CB Open
and
CB Close
).
•
Disabled
: commands 7 and 8 are not valid.
IMPORTANT: in this case, remote circuit-breaker opening and closing can still be
obtained using the programmable YC COMMAND and YO COMMAND functions and
the Request circuit-breaker opening (28) and Request circuit-breaker closing (29)
commands.
Modules network settings
retention
It allows the communication parameters of the circuit-breaker to be controlled if the trip unit is replaced:
•
Overwrite
: the parameters of the new trip unit are valid, so it is advisable to make sure that the communication
parameter settings suit the communication network.
•
Keep module data
: the new trip unit updates its communication parameters with the ones in the Ekip
Com modules of the circuit-breaker, used up to that moment in the various communication networks.
The trip units are supplied with the parameter set as
Overwrite
.
Change Double Set of
parameters always
If activated, it allows the modification of the parameter set even when delay alarms are in progress.
Disabled
by default.
Repeat zone selectivity S/G HW
If
Enabled
, the propagation logic of HW signals for zone selectivity applies in accordance with the table
in the Technical Application Paper QT1.
Disabled
the HW selectivity signal is not
propagated by the protection trip unit.
Zone selectivity input functions
The zone selectivity inputs and some outputs can be configured in this section:
•
Standard
: input or output operation as per standard zone selectivity logic (see
or
); all selectivity functions have the
Standard
setting.
•
Customized
: the event that activates the zone selectivity input or output can be selected.
IMPORTANT: in the Customized configuration, the only zone selectivity activation
event is the one set and therefore standard selectivity operation is not active
(modification should only be performed by expert technical personnel).
