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.
6.4 Time-controlled blast chilling and storage
The time-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 and the LED will flash.
4. Press and release the TIME/TEMPERATURE key: the LED flashes and the LED will switch off.
5.1 If parameter r19 is set at 0, the 4 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 3 digit display will show the blast chilling duration; this value can also be set
via parameter r1.
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 and the LED will remain permanently on and the cycle
will be started.
Operate as indicated to stop the cycle:
7. Hold the START/STOP key down for 2 s.
During blast chilling, the 3 digit display shows the residual time of the blast chilling duration and the 4 digit display
shows the cabinet temperature.
To modify the residual time, operate as indicated:
8. Press and release the UP or DOWN key again to modify the time value: the display will flash.
9. 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.
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.
On expiry of the blast chilling duration, the device automatically passes to storage mode and the buzzer is activated
for the time period established with parameter AA.
Press and release a key to silence the buzzer.
During storage, the 3 digit display shows blast chilling duration, the 4 digit display shows the cabinet temperature and
the LED is on.
Parameter r10 establishes the work set-point during storage.
6.5 Time-controlled hard blast chilling and storage
The time-controlled hard blast chilling and storage cycle is divided into the following three phases:
- blast chilling hard phase
- blast chilling
- storage.
