Automatic documentation and alarm functions
Documentation is an unavoidable and time-consuming part of everyday laboratory life. And, for many applications, data recording is required for more than just legal reasons: continuous recording and monitoring are crucial to the validity of tests and, in the case of incidents, these records document the course of events and responsibilities.
Liebherr appliances with Profi electronic controls have integrated data storage for automatic documentation purposes. All models can be integrated into the existing on-site infrastructure, individually or via serial interfaces.
Functions and accessories for documentation
24/7 monitoring
Appliances with a Profi electronics can be connected to an external alarm system by means of a potential-free contact. This ensures that the refrigeration process is continually monitored and documented, whether or not staff are present.
Integration into existing systems
The central data management system reduces the documentation-related workload. The RS 485 serial interface can be used to network up to 20 appliances. An optionally available interface converter connects the networked appliances to a computer, and the documentation software notifies the relevant personnel about any alarms by e-mail and provides all the data required.
Continuous documentation
In the event of uncertainty, the continuous documentation can reveal where the blame lies if temperature fluctuations and incidents activate alarms. The integrated data memory records over 2,000 temperature readings at regular intervals to enable differentiated analysis.
Simple data analysis
The optionally available infrared key, including documentation software, facilitates data analysis. The software visualises relevant information in different formats and charts. Furthermore, the program can be used to easily export data into Excel and Word.
Special emergency backup
For maximum safety, all LKPv and LGPv appliances have an SSR (solid state relay). This not only ensures precise temperature regulation but also perfect, year-round control of refrigeration technology.
