4 - Datalogger

Presentation 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
Datalogger 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

Parameters 1 The parameters and commands of the function are available in the Settings - Datalogger menu (page 29).
Parameter Description Default
Activates/deactivates the function and its availability in the
parameters menu
Enable Off
NOTE: il the enable command is hidden when at least one
datalogger is activated
Determines the number of recordings (1 or 2)
NOTE: the recordings share the settings of the sampling
Num. of frequency and type of memory 1
Datalogger
IMPORTANT: Change the parameter with interrupted or
not started recording
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)
Sampling
frequency NOTE: 9600 Hz
• A high frequency allows the data to be analyzed more
accurately
• if there are two dataloggers, the recording window of each
recording is halved
Datalogger 1 Menu with the parameters of each Datalogger: trigger event,
and 2 recording delay and Restart/Stop commands
Restart and Synchronized start and stop commands of the two dataloggers,
Stop Both valid and available with Num. of Datalogger = 2
