Presentation
Datalogger
The datalogger is a function which allows data associated with a trigger event to be recorded. The following
data are recorded:
• Analog measurements: line-to-line voltages and phase currents
• Digital events: protection events or alarms, circuit-breaker status signals, protection trips.
One or two independent recordings can be configured and, via Ekip Connect, all the associated information
can be downloaded, displayed and saved.
Function
When the datalogger is enabled and activated (
RESTART
), Ekip Touch continuously acquires data by filling
and emptying an internal buffer (
B
).
If a trigger event (
A
) occurs, Ekip Touch interrupts acquisition (
STOP
) immediately or after a time that can
be set by the user (
C
) and stores all the data of the window (
D
), which can then be downloaded to a PC for
reading and analysis.
IMPORTANT: the function requires an auxiliary voltage supply

Parameter
Description
Default
Enable
Activates/deactivates the function and its availability in the parameters
menu
NOTE
:
il the enable command is hidden when at least one
datalogger is activated
Off
Num. of
Datalogger
Determines the number of recordings (1 or 2)
NOTE
:
the recordings share the settings of the sampling
frequency and type of memory
1
Sampling
frequency
Establishes the number of samples acquired per second and the
recording window.
Four options are available: 1200 Hz (window= 13.6 s), 2400 Hz (6.8
s), 4800 Hz (3.4 s), 9600 Hz (1.7 s)
NOTE
:
•
A high frequency allows the data to be analyzed more
accurately
•
if there are two dataloggers, the recording window of each
recording is halved
9600 Hz
