Parameters that can be the set and the commands of the function are:
Parameter Description
Number of
dataloggers
It selects the number of recordings (1 or 2).
NOTE: the recordings are independent, but they share the sampling frequency
and the type of memory.
Sampling
frequency
It determines the number of data logs recorded. There are four options available: 1200,
2400, 4800, 9600 Hz.
IMPORTANT:
• A high frequency allows a more accurate analysis of the data.
• The higher the frequency, the shorter the recording.
Datalogger 1
It allows the user to set the parameters and to manually command recording number 1.
• Stop Source: it selects the trigger event, on the occurrence of which the recording is
to be stopped.
• Stop Delay: it sets the delay after the trigger event after which recording is to be
stopped
• Restart command: it starts recording.
• Stop command: it stops the recording and saves it in memory.
IMPORTANT: the recording can only be downloaded with the Ekip
Connect application.
The selection of two recordings activates additional parameters and commands:
Parameter Description
Datalogger 2 Like Datalogger 1, but relevant to recording number 2.
Restart all It starts both the recordings.
Stop All It stops both the recordings and saves them in memory.
With Ekip Connect software it is possible to select the parameter Memory Type, not available on the display.
Such parameter allows to choose whether to keep the recording also with the trip unit off (non-volatile) or to
delete it if the auxiliary power disappears (volatile).
NOTE: the parameter is configured by default as non-volatile.
• If Memory Type = Non volatile, the life of the internal battery of Ekip Touch may be sensibly lower
than the declared value in case a recording is stored but auxiliary power supply is not present.
• If the Memory Type is Volatile and the auxiliary supply is lost, the datalogger will rerun the
recording when re-powered and the previously memorized data will be lost.
Operation counters
Path
Main page - Menu - About - Circuit-breaker
Description
In the presence of auxiliary power, the trip unit records a series information relating to the openings of the
circuit-breaker:
• The number of manual openings.
• The total number of operations (manual + trips).
By activating the communication with the trip unit, the following counters are also available:
• The number of openings due to tripping of protections.
• The number of openings due tripping of failed protections.
• The number of opening tests performed.
Summary table of basic
measurements
The following table summarises the basic measurements:
Quantities measured Monitor time Normal operating range Accuracy
Phase currents (I1, I2, I3, Ine) 0.03…16 In 0.2…1.2 In 1 %
Earth fault current (Ig) 0.08…4 In 0.2…1.2 In 2 %
NOTE: the accuracies refer to normal operating ranges, as established by IEC 61557-12.
