6.10.1 USB Data Recorder Operation (Units post 4/16)
The USB data recorder will register into a .txt file all the
data during the cycles of the machine; Blast Chilling or

The data is registered every minute and will include:
- Date and Time
- Cabinet Temperature
- Core Probe Temperature
- Type of Cycle
- Start and Stop Cycle

- Door Openings
- Alarms
The data is constantly stored on the internal recorder and
can be downloaded anytime from the internal recorder by
introducing a USB drive into the USB port on the machine.
Instructions to download the data:
1. Insert the USB drive.
IMPORTANT: wait until the LED of the USB drive
stops flashing, which means that all the data is
recorded on the USB drive.
2. Extract the USB drive.
3. On the USB drive you will find a file named lon00n000001.
txt which is a text file, delimited with ";" (semicolon).
Every time you insert the USB drive, a new log file will be
generated, with a progressive number (log00n000002.txt,
log00n000003.txt, etc).
Every file generated will contain the complete historical
data recorded, up to the moment of insertion of the USB
drive. As a consequence, the time to save the file on the USB
drive will increase from some seconds to several minutes,
depending on how much data is stored on the recorder.
NOTE: It's very important to wait until all the data recorded
on the USB drive before removing it, wait until the LED on
the USB drive stops flashing.
The best way to see the data on the file is using Microsoft
Excel (as an alternative you can open the file with a normal
text editor), following this sequence:
1. Launch Microsoft Excel.
2. Go to "open file".
3. Select "text file" on the type of file.
4. Open the file registered on the drive.
5. Select "delimited" file.
