2. Quick Start

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 and Communication Behaviour

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 Alarm on/off icon changes to Alarm 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 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.

4.4 Menu

The LIBERO G family feature a menu to operate the device:

·         To enter the menu, press the Menu button for at least three seconds

·         To switch between the menu options, press the Info button shortly

·         To select a menu item, press the Menu button for at least three seconds. To confirm, a selected menu item blinks once.

i the menu item FCT.RESET hast to be confirmed by pressing the Info button again shortly

·         to leave the menu

o   wait for 5 seconds

o   press the Start/Stop button

o   select the last menu item EXIT

All menu items and its availability are described in the table below (now menu available in SHELFLIFE / SLEEP mode)

5.1 Pairing procedure

5.2 Start before Date & Expiry Date

The Start before Date indicates the latest possible start of the device. The date (MMM/yyyy) is visible on the device label or via the display (before first device start)

• Device cannot be started afterwards (for Multi use devices: only applicable to initial start)

The Expiry Date indicates the end of the runtime of the device. The date (MMM/yyyy) is visible via the display (> Menu) or in the Cloud. The runtime is calculated from the initial start date.

• Device stops automatically (logging and communication)

6. Accessories

6.1 Bracket

ELPRO offers an optional bracket BRA_LIBERO Gx, part number 802286, for mounting of data loggers if required, i.e. to containers for cryogenic applications. The bracket is made of solid ABS plastic to protect the data logger but not influence the communication. It consists of an upper and a lower part. The LIBERO is inserted into the lower holder from above.

6.2 External Pt100 Probes for LIBERO GE

LIBERO GE can be used for different applications, depending on the sensor element. ELPRO offers standard probes for three main applications:

·         Cryogenic shipments and storage

·         Dry ice shipments and storage

·         Freezer (-25 °C..-15°C, typical) / fridge (+2 °C..+8 °C) / ambient (+15 °C..+25 °C) shipments and storage

i to ensure correct measurement values, do only use external sensor elements provided by ELPRO

6.2.1 Cryogenic shipments and storage

For cryogenic applications the LIBERO GE is usually mounted directly to the container or the container lid, using the optionally available bracket with the sensor leading into the tank. ELPRO offers an easy, turnkey service for mounting the assembly and calibration.
