Function description
LAUDA Versafreeze freezer cabinet models VF 15040, 60040 and 70040 are equipped with a high-performance
com- pressor and operate within a variable temperature range of -0 °C to -40 °C. Models VF 15085, 60085, and
70085 are equipped with two high-performance compressors and operate at a temperature range of -50 °C to -85 °C.
The air- cooled condenser on the back of the appliance releases heat extracted from the refrigeration compartment into
the room. The temperature controller maintains a constant temperature in line with the preset value.
The current temperature in the refrigeration compartment is shown on the controller display.
Function of data logger, history
The data logger starts automatically and records the temperature in the refrigeration compartment, the condenser tem-
perature, and the internal battery voltage every 120 seconds. Different views, e.g. days or hours, can be selected by tap-
ping the "Data logger, history" symbol.
To view past events, tap the
symbol to open a window for setting the start and end dates. Now choose the desired
start and end dates, tap to select, then press OK to confirm. Tap an hour or day to return to the current display. The data
logger is fitted with a 1 GB industrial SD card and can therefore record data for 2 years before the memory is full. When
the memory is full, the oldest data is overwritten first so that only the most recent data is retained. We recommend ex-
porting the data, e.g. every six months, depending on its importance, or performing more regular backups (see Data trans-
fer via USB).
Selection of displayed control curves:
Briefly tapping the symbols An1, A2F, or ba1 shows the designation of the symbols on the left of the display.
All three control curves are selected by default. In order to display only one control curve, the other control curves must
be deactivated. To deactivate a control curve, press the corresponding symbol and hold for approx. 3 seconds. The symbol
turns white and the control curve disappears. To activate the control curve, press the deactivated white symbol and hold
for approx. 3 seconds until it reverts back to its original color.
