Access from the Ekip Connect
Setting the function
Apart from few parameters, the function can only be set via the Ekip Connect software (see the chapter
“16 - Other accessories", and the paragraph "Ekip Connect software”).
NOTE:
the parameters for setting the function are available only if the trip unit is equipped
with an Ekip Measuring module. In this case, the Advanced Power Controller menu on Ekip
Connect is activated, under which the following pages can be selected.
On the
Basic Information and Settings
page of the master, the Power Controller function needs to be
enabled.
On the
Advanced Information and Settings
page of the master, the following must be set:
• If at start-up, in order to be considered available, the loads can be both closed and open, or must be
closed, or if they are to be considered non-available in any case until the manual command for cancelling
alarms has been selected on the
Basic Information and Settings
page.
• Within the monitoring period (5 minutes by default; it can be set from the
Unit Configuration
page, used
for the general configuration of trip units and installation), how often the function is to be performed (the
energy at the end of the period must be estimated and the loads must be checked).
• In relation to this time, the percentage of delay with which loads can be disconnected and connected.
• In the presence of an external time synchronization signal, the master signalling input to which it is
connected (input of the Ekip Signalling 4K module installed on the trip unit, or the 2K or 10K modules
connected to the trip unit via Local Bus). For more information on synchronization, see the White Paper
"Load management with Ekip Power Controller for SACE Emax 2".
• Up to ten power limits, of which at least the first one must be set.
• For each day of the week, up to a maximum of four time bands (which must cover a total twenty four
hours), and for each time band one of the above-mentioned ten power limits.
On the
Parameters Load
pages of the master, the parameters of the loads must be set (separately for each
load):
• If the load has to be disconnected and connected manually, or automatically by the master.
• The priority level, from 1 to 15 (the higher the level, for example 15, the more important the load. The lower
the level, for example 1, the less important the load).
• The load type, in other words whether it is a real load or a generator.
• The number (from 0 to 2) and type of information on the state of the slaves on the supply side of the load
(open/closed, not available, in tripped position).
• The type of inputs, in other words, how the above state information is supplied (through physical connection
of inputs, or via Link Bus using one of the 15 Ekip Link modules that can be associated with the master).
• In case of physical inputs, to which signalling inputs of the master the above state signals are connected.
• The minimum time for which the load must remain connected.
• The minimum time for which the load must remain disconnected.
• The maximum time for which the load can remain disconnected.
• The start time and end time of a possible time slot in the day during which the load cannot be disconnected.
NOTE:
if the non-availability signal of a load is active, the load cannot be disconnected and
connected, and therefore it cannot be used for the function until it becomes available again.
