Description of the function The function Datalogger allows the recording of data associated with a trigger event. The data recorded are:
analog measurements, i.e. phase currents and line-to-line voltages
digital events, i.e. protection events or alarms, circuit-breaker status signals, protection trips.
IMPORTANT: the function Datalogger requires an auxiliary voltage supply.
Operating principle When Data Logger is enabled and activated, the device continuously acquires data by filling and emptying an internal buffer (B).
If the trigger event is encountered (A), the device interrupts the acquisition immediately or after a user-definable time called the stop delay (C). Next, it saves all the data in the window (D), which can then be downloaded to a PC for reading and analysis.
A subsequent recording overwrites the previous one in the device memory.
Datalogger in Ekip Connect From Ekip Connect the following actions can be performed:
enable/disable the function
Start/Stop recording
configure recording parameters
download the recording to analyze it with function Data Viewer

Settings Data Logger
Configuration is mainly done in the "Options" window which is reached via "Download options" button from tooltip.
Options window mainly consisted of 2 parts ; "General" and "Trigger" sections.
In section "General", enabling of function and usual configuration for the datalogger is managed. User decides the number of the register in sample, sampling frequency and stop delay for that datalogger record.
Element
Description
Datalogger enabled
A button to enable/disable datalogger functionality
Number of register in sample
Number of register in sample (8, 16, 32)
Sampling frequency
Frequency of data collection. The higher the sampling frequency, the shorter the recording duration. (1200, 2400, 4800, 9600)
Stop delay
A button to set stop delay. It refers the duration, in seconds, of the recording after the trigger event. Maximum limit is 10 sec and available.
In section Trigger, user selects the desired trigger from the list of trigger event.
Start recording
With the device connected and communicating with Ekip Connect, click on Tools > Data Logger.
Check that the status of the command to enable the function (Download options --> Enable) is Enabled .
Click on and configure recording in "General" section.
To cancel the changes, click on Cancel. To save the configuration, click on OK : the settings are automatically saved and transmitted to the device.
Click on Trigger and set the trigger type.
To cancel the changes, click on Cancel. To save the configuration, click on OK: the settings are automatically saved and transmitted to the device.
Click on Start Datalogger: Recording is initialized.
Click on Stop Datalogger: Recording is stopped and ready to download.
IMPORTANT: once started, the function remains active on the device regardless of the status of the connection and communication with Ekip Connect.
Download a recording
With the device connected and communicating, click on Download Datalogger .
Note: the Download button is available only if there is a recording.
Select where to save the file and the interval of the recording you want to download: Ekip Connect saves an .abb file named according to the following syntax: CBTagName_Datalogger_YYYYMMDDhh:mm:ss.
Note: if communication with the device is via a point-to-point connection, it can take up to 5-10 minutes to download the file. With a bus network connection, the operation is faster.
Download only the recording interval with useful data to reduce download times.
Please consult the table below which shows the relation of frequency and register in sample with recordable datalogger file size.
Download only the recording interval with useful data to reduce download times.
