2. Quick Start

1. Visit the elproCLOUD login, tipe in your credentials or register a new account.

2. Click on “Add Sensor” and tipe/scan the logger ID. Set the configuration you want the data logger to work with by clicking through steps 1-5.

3. Once you have finished the configuration, press the Start button for 3s. LIBERO G will operate in the set configuration and is ready for use.

4. Place LIBERO G in your application and monitor the captured data in elproCLOUD.

5. Upon arrival at the destination, the recipient can simply scan the QR code on LIBERO G to read the loggers data.

6. Detailed and video supported instructions for the configuration of LIBERO G in the elproCLOUD and further information can be found on the ELPRO online knowledge base.

3. System Overview

The LIBERO Gx realtime data logger family described in this document are used for temperature monitoring. The measured values are transmitted via the cellular network to a monitoring software (ELPRO Cloud) which stores and analyzes the data, provides alerts if alarm limits are violated, and generates reports. The system provides superior visibility and transparency in meeting GxP requirements. The sensor-based monitoring software is easily accessible via a web browser and is also used to configure the devices.

The following pages cover the key functionality of the Wireless data logger (LIBERO GS/GL/GF/GE/GF ext/GH) For more detailed software support, please visit our online knowledge base:

4.2 Display

4.3 States

LIBERO Gx devices are mainly used to monitor temperature-sensitive products throughout the entire supply chain. The device offers various configuration options. The device states are visualized below and further described in subsequent chapters. The workflow options may vary depending from configuration and device type (e.g. single use).

Shelflife

When delivered, the device is in SHELFLIFE state.

·         In this state, the device is not transmitting and the display is switched off.

·         By pressing the Info button (shortly), the battery level as well as the Start before Date / Expiry Date are visible

·         By pressing and holding the Start/Stop button for 3 seconds, the device will activate communication

Configuration

In the CONFIG mode, the device connects immediately to elproCLOUD to retrieve the configuration. The display shows CONFIG.

·         When entering this state, the device communicates in a higher frequency for the first 30 minutes

·         After the receipt of the configuration, the device enters START mode immediately

·         By pressing the Info button the Start before Date / Expiry Date is visible

Start

When the display shows START, the device is configured properly and can be started according to the chosen start option.

·         By pressing the Info button the Profile information / configured info field / Start before Date / Expiry Date is visible

·         By pressing the Start/Stop button, the device starts logging (TRANSIT or DELAY). The RUN icon on the display indicates a successful start.

The Start/Stop button is inactive for 2 minutes after start

To reconfigure a device, delete the sensor in the cloud and reset the device

Delay

Depending on the activation mode, the device will enter into DELAY or TRANSIT.

·         The display indicates the DELAY mode by showing DELAY.

if DELAY mode “press button to activate alarm limits” is configured, the display shows DELAY

if DELAY mode “time delay” is configured, the display shows the remaining time

·         By pressing the Info button the actual measurement value / configured info field are visible

Transit

In TRANSIT, the alarm limits are activated (if configured). The Alarm on/off icon appears (Alarm on).

·         By pressing the Start/Stop button, the device enters ARRIVED mode. The RUN icon on the display disappears.

Ensure to pack the device as such that the start / stop button is not pressed accidentally

·         By pressing the Info button the second measurement value (for LIBERO GH/GE) / configured info field are visible

Pause

When the alarm limits are deactivated, the device will enter PAUSE mode. The Alarming on/off icon changes to Alarming off. The device remains logging and transmitting.

·         By pressing the Info button the second measurement value (for LIBERO GH/GE) / configured info field are visible

Arrived

After terminating the TRANSIT mode, the device will enter ARRIVED mode. The RUN icon on the display disappears. The device will still log and communicate (interval 2 hours) for 72 hours or until stopped.

·         By pressing the Start/Stop button, the device enters STOP mode.

·         By pressing the Info button the measurement values / configured info field / Expiry Date are visible

Stop

In STOP mode, the device will not log any measurement data. The device first communicates at a faster interval (3 minutes) for 20 minutes to upload remaining buffered data, and then communicates at a reduced interval (12 hours) for 24 hours.

·         By pressing the Info button the configured info field / Expiry Date are visible

·         By pressing the Menu button, the following menu options are available (select by pressing Menu button):

Sleep

After stop, the device is in SLEEP mode.

·         In this state, the device is not transmitting and the display is switched off.

·         By pressing the Info button (shortly), the battery level as well as the Expiry Date are visible

·         By pressing the Start/Stop button for 3 seconds, the device will activate communication and enter STOP mode.
