6 OPERATION
6.1 Foreword
The devices can manage the following operating cycles:
-
blast chilling and storage
- hard blast chilling and storage
- deep freezing and storage
- soft deep freezing and storage.
For further information, see the next paragraphs
Every operating cycle can be preceded by pre-cooling; see paragraph 6.6 "Pre-cooling".
The temperature-controlled cycles are preceded by a test to verify the correct insertion of the needle probe; see
paragraph 6.7 " Test for verification of the correct insertion of the needle probe".
If the needle probe is not enabled, i.e. if parameter P3 is set at 0, the temperature-controlled cycles will be started
with time-control.
The following functions can also be used:
-
switching on sterilisation cycle UV light
- heating the needle probe.
For further information, see the next paragraphs
6.2 Blast chilling and storage
The temperature-controlled blast chilling and storage cycle is divided into the following two phases:
- blast
chilling
- storage
On conclusion of a phase, the device passes automatically to the next.
Operate as indicated to start the cycle:
1.
Make sure the device is in the "on" status.
2. Make sure that the keyboard is not locked and that no procedure is in progress.
3. Press and release the BLAST CHILLING key: the LED will flash.
4.1 If parameter r19 is set at 0, the display will show the work set-point during blast chilling; this value can also be
set via parameter r7.
4.2 If parameter r19 is set at 1, the display will show the blast chilling end temperature; this value can also be set
via parameter r3.
4.3 Press and release the UP or DOWN key within 15 s to modify the parameter value.
5. Press and release the START/STOP key: the LED will remain permanently on and the test to verify the
correct insertion of the needle probe will be started; see paragraph 6.7 " Test for verification of the correct
insertion of the needle probe".
5.1 If the test is completed successfully, the cycle will be started.
The maximum blast chilling duration count is started on condition that the temperature detected by the
needle probe is below that established with parameter r15.
5.2 If the test is not completed successfully, the cycle will be started with timed-control.
During blast chilling, the display shows the residual time of the blast chilling duration and the LED is
on.
To modify the residual time, operate as indicated:
5.2.1 Press and release the UP or DOWN key again to modify the time value: the display will flash.
5.2.2 Do not operate for 4 s: the display will stop flashing and remain on permanently.
The successive parameters establish the following values:
- parameter r1 establishes blast chilling duration
