Translation of the original operating manual
• Press the start button in order to start the rapid cooling process.
• During the rapid cooling process, the set temperature can be modified
within the range below the actual temperature.
The current status of the program will be displayed on the status bar.
The “RAPID_TEMP“ program will be stopped under the following
conditions:
• The set value is reached. In this case, the “RAPID_TEMP” program
stops with a sound signal and the standstill cooling will be activated.
• The stop button is pressed. The “RAPID_TEMP” program will be
stopped prematurely. No message will be issued when the set
temperature is reached.
• A parameter is changed (except for the temperature) or another input is
made. In this case, the “RAPID_TEMP” program will be aborted. No
message will be issued when the set temperature is reached.
After the stop, the previous program will be reloaded or the changed
parameters will be adopted as the new settings.
NOTE
The automatic lid opening function is suppressed after a rapid cooling
process in order to prevent the system from reheating.
NOTE
The delta T temperature monitoring system (see chapter (see chapter
6.3.2.6 - "
Parameters menu
"), Process) remains inactive as long as the
"RAPID_TEMP" program is active.
NOTE
If the "RAPID_TEMP" program is used, the temperature of the unloaded
aluminium bucket will be displayed. If samples, which have not been
precooled, are placed into the buckets, the displayed temperature will
deviate from the actual sample temperature.
Acceleration
This function is used to select an acceleration curve. One can select a
linear rise (curves 0-9) or a quadratic rise (curves 10-19). The acceleration
curves 20-29 can be programmed as desired.
Their shape is explained in detail in (see chapter 11.3 - "
Acceleration and
deceleration curves
").
Deceleration (Brake)
This function is used in order to select a curve that decelerates the
centrifuge to a standstill. Deceleration curves are inverted images of the
acceleration curves and are labelled with identical numbers. Deceleration
curve no. 0 represents a brakeless deceleration.
