Data Logger

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.
Operating principle

 

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.

Number of register in sampleNumber of register in sample (8, 16, 32)
Sampling frequencyFrequency of data collection. The higher the sampling frequency, the shorter the recording duration. (1200, 2400, 4800, 9600)
Stop delayA 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

  1. With the device connected and communicating with Ekip Connect, click on Tools > Data Logger.
  2. Check that the status of the command to enable the function (Download options --> Enable) is Enabled .
  3. Click on Settings and configure recording in "General" section.
  4. To cancel the changes, click on Cancel. To save the configuration, click on OK : the settings are automatically saved and transmitted to the device.
  5. Click on Trigger  and set the trigger type.
  6. To cancel the changes, click on Cancel. To save the configuration, click on OK: the settings are automatically saved and transmitted to the device.
  7. Click on Start Datalogger: Recording is initialized.
  8. 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

  1. With the device connected and communicating, click on Download Datalogger .
Note: the Download button is available only if there is a recording.
  1. 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.
Bulb Icon Download only the recording interval with useful data to reduce download times.

Datalogger Pro 

The Data Logger Pro allows current and voltage waveform, alarms, and digital signals data associated with an event to be recorded. An SD card installed on the circuit breaker is necessary for this functionality, enabling longer recording durations. Additionally, the Pro version provides more variables compared to the basic version, offering a comprehensive overview of system events.

 

 Prerequisite:

  1. The tool is only available to operate if the "Datalogger Pro" Digital Upgrade is present and activated in the connected Sace Emax 3 breaker.
  2. The tool is operable with Flash memory (SD card), which should satisfy the following specifications:
  • Standard SD cards* <= 2GB are not supported.
  • Extended or HIGH capacity SD cards* up to 512GB are supported.
     
*A warning is generated if SD card size <48GB


When all the prerequisites are satified, the Datalogger Pro section will appear. Click on the Options button to perform the configuration.

 

By accessing the "General" section, parameters such as the number of registers in sample, sampling frequency, stop delay and the enabling of datalogger can be set.

Sampling frequencyFrequency of data collection. The higher the sampling frequency, the shorter the recording duration. (1200, 2400, 4800, 9600)
Stop delaySet the stop delay, which is available only if "Single trigger" modality is selected. It refers to the duration, in seconds, of the recording after the trigger event. Maximum limit is 10 seconds.

 

 

In the"Trigger" section there are two modalities available, "Single Trigger" or "Multi trigger". The latter one enables the possibility to set up to three different triggers.
  

Single Trigger

In Single trigger modality, you can set the Trigger type from the list of pre-defined trigger events or even a customized one according to your needs.

 

Multi Trigger

In Multi trigger modality, you can set trigger types independently for up to 3 triggers. A maximum of 30 total trigger events can be recorded during a single registration.

Download a recording

Click on Download Datalogger and you will be presented with a window containing dedicated sections to be filled and selected.

 

  
FilenameChoose the name of the datalogge file and the directory. By default file name is in CBTagName_Datalogger_YYYYMMDDhh:mm:ss format. File extension must always be ".abb" . 
Trigger offset selectionAllows you to select the trigger event to be downloaded in case the Multi Trigger modality is chosen.
Free offset selectionProvides a cursor on the timeline with which you can choose at which timestamp to start the download operation. It allows the download window to be centered on an absolute time. Available when the Multi Trigger modality is chosen.
Time windowTime-based window for selecting the start and end of the Download. You can reduce or enlarge the window by scrolling the two cursors.

 

The Datalogger file can be downloaded through Ekip Connect when the SD card is still mounted in the Ekip Aware trip unit or you can unmount the SD card and open directly the datalogger file in the Dataviewer tool. The maximum DataLogger file size in seconds downloadable through Ekip Connect without unmounting the SD card is defined by a precise combination of the number of registers and frequency used:

FrequencyRegister Size (s) 
12008218.453
16109.227
3254.613
6427.307
