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 and the LED will flash.
4. Press and release the HARD/SOFT key: the HARD LED will flash.
5.1 If parameter r19 is set at 0, the 3 digit display will show the work set-point during blast chilling; this value can
also be set via parameter r7.
5.2 If parameter r19 is set at 1, the 4 digit display will show the blast chilling end temperature; this value can also
be set via parameter r3.
5.3 Press and release the UP or DOWN key within 60 s to modify the parameter value:
6. Press and release the START/STOP key: the LED, the LED and the HARD LED will remain permanently
on and the test to verify the correct insertion of the needle probe will be started; see paragraph 6.14 " Test for
verification of the correct insertion of the needle probe".
6.1 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.
6.2 If the test is not completed successfully, the cycle will be started with timed-control; see paragraph 6.5
"Time-controlled hard blast chilling and storage".
Operate as indicated to stop the cycle:
7. Hold the START/STOP key down for 2 s.
During the hard blast chilling phase, the 3 digit display will show the temperature detected by the needle probe and
the 4 digit display shows the cabinet cell.
The successive parameters establish the following values:
- parameter r5 establishes the maximum blast chilling duration
- parameter r9 establishes the work set-point during the blast chilling hard phase
- parameter r13 establishes blast chilling hard phase end temperature.
When the temperature detected by the needle probe reaches the hard blast chilling phase end temperature, the device
automatically passes to blast chilling mode.
During blast chilling, the 3 digit display will show the temperature detected by the needle probe and the 4 digit display
shows the cabinet cell.
The successive parameters establish the following values:
- parameter r3 establishes the blast chilling end temperature
- parameter r5 establishes the maximum blast chilling duration
- parameter r7 establishes the work set-point during blast chilling.
To display the cabinet work set-point during blast chilling, press and release the BLAST CHILLING, DEEP FREEZING or
the HARD/SOFT key; to restore the normal display, press and release the same key again or do not operate for 60 s.
If the temperature detected by the needle probe reaches the blast chilling end temperature within the maximum blast
chilling duration, it means that blast chilling has been completed successfully, the device will automatically pass to
storage and the buzzer will be activated for the period of time established with parameter AA.
Press and release a key to silence the buzzer.
During storage, the 3 digit display shows the time taken to complete blast chilling successfully, the 4 digit display
shows the cabinet temperature and the LED is on.
Parameter r10 establishes the work set-point during storage.
If the temperature detected by the needle probe does not reach the blast chilling end temperature within the
maximum blast chilling duration, blast chilling will not be completed successfully but will continue, the LED will
flash and the buzzer will be activated.
