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
- parameter r7 establishes the work set-point during blast chilling.
Operate as indicated to stop the cycle:
6.
Hold the START/STOP key down.
During blast chilling, the display shows the temperature detected by the needle probe and the LED is on.
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 temperature, 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 15 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 display shows the temperature detected by the cabinet 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.
Press and release a key to restore normal display and to silence the buzzer.
To display the cabinet temperature, press and release the BLAST CHILLING key; to restore the normal display, press
and release the BLAST CHILLING key again or do not operate for 15 s.
When the temperature detected by the needle probe reaches the blast chilling end temperature, the device
automatically passes to storage in the same way as illustrated previously.
6.3 Hard blast chilling and storage
The temperature-controlled hard blast chilling and storage cycle is divided into the following three phases:
-
blast chilling hard phase
- 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 and the LED will flash.
If parameter r21 has value 1, press and release the BLAST CHILLING key to start the cycle with timed-control:
the LED and the LED will flash and the LED will switch off (press and release the BLAST CHILLING
key again to start the cycle with temperature-control).
