Material safety data sheet according to provisions of directive 91/155/EEC and shipping information are available from ELPRO-BUCHS AG. Do not subject the batteries to mechanical stress nor dismantle them. The leaking battery fluid is highly corrosive and can generate severe heat when it comes into contact with moister or it can ignite fire.
3 System Overview The LIBERO CE data logger described in this document is a device for temperature monitoring using an external Pt100 probe. LIBERO CE saves the temperature measurements and can generate a PDF report when connected to a USB port on your computer. The PDF report contains all measured values and thus creates visibility and transparency to fulfil GxP requirements.
4 Device - LIBERO CE 4.1 Functionality and Modes After configuration, the device measures the temperature using the connected external sensor, stores the measured values and evaluates them with regard to the defined alarm criteria. The display indicates the current mode.

After the delay (if configured) has elapsed, the device switches to measurement mode. Depending on the device’s configuration, we can distinguish between the following two types of measurement mode. - Measurement mode without "Alarming ON/OFF" function: Displays the current temperature value (bottom, if configured), alarm indicator (top right, if configured) and the logging indicator (top left).

In stop mode there can be two different display states as seen below. Immediately after stopping, "Make PDF" appears. This will only disappear after the PDF report has been created by plugging the device into a USB port. This ensures that the user does not forget to read out the device. After the device has been read out, "Stop"...
4.2 Workflow 4.2.1 “Alarming ON/OFF” function not configured The following figure shows the sequence of modes if the "Alarming ON/OFF" function has not been configured (see chapter 6.1, section Alarm Conditions). 4.2.2 “Alarming ON/OFF” function configured The following figure shows the sequence of modes if the "Alarming ON/OFF" function has been configured (see chapter 6.1, section Alarm Conditions).
5.1.1 Cryogenic shipments and storage For cryogenic applications the LIBERO CE is usually mounted directly to the container, or the container lid, using the optional bracket with the sensor leading into the tank. ELPRO offers an easy, turnkey service for mounting the assembly and calibration.

ELPRO offers two standard probes with different probe lengths for this application: PRO_PT100_ST300D3_M8_CRYO (part number 802287) PRO_PT100_ST350D3_M8_CRYO (part number 802288) 1000353V02 DOC_Operation Manual LIBERO CE_EN.docx | Page 12 / 22...
5.1.2 Dry ice shipments and storage Also in dry ice applications, the LIBERO CE is usually attached to the outside of the container using the optional bracket and the sensor leads into the tank. ELPRO offers an easy, turnkey service for mounting the assembly and calibration.

5.1.3 Freezer / fridge / ambient shipments and storage For temperature monitoring of freezers, refrigerators or rooms, ELPRO offers two waterproof silicon Pt100 probes with different cable lengths as standard articles: PRO_PT100_P20D5_PLA1_M8 (part number 802290) PRO_PT100_P20D5_PLA2.65_M8 (part number 802291) 1000353V02 DOC_Operation Manual LIBERO CE_EN.docx | Page 15 / 22...
Waterproof silicon Pt100 probe for freezer/fridge/ambient temperature monitoring with M8 connector 5.1.4 Extension of sensor cables An extension cable with a length of 1m is also available. ATTENTION: The total cable length (including sensor and cable tail on the data logger) must not exceed 3 m.
Details regarding configuration of LIBERO Cx can be found in the corresponding manual (https://shop.elpro.com/daten/img/Documents/Operation%20Manuals/LIBERO/OM_LIBEROC_EN_web. pdf). In the following, only the differences or additional configuration options for the LIBERO CE are described. 1000353V02 DOC_Operation Manual LIBERO CE_EN.docx | Page 17 / 22...

Logging “Loop” was added as an additional logging mode, as LIBERO CE is a multi-use device. NOTE: If the memory of the logger is full, newly measured values will continuously overwrite the oldest values. 1000353V02 DOC_Operation Manual LIBERO CE_EN.docx | Page 18 / 22...

Alarm Conditions In the section "Alarm Mode" the possibility to select the inspection range has been added. The following options are available: All data: all recorded values are taken into consideration when assessing the alarm status (based on the configured alarm conditions) ...

(so stopping is basically possible, but the logger will hardly ever be stopped accidentally) Stop mode disabled (CAUTION: This turns LIBERO CE into a 3-year single-use device, as it cannot be stopped and therefore the configuration cannot be changed!)
