During deep freezing, the display shows the residual time of the deep freezing 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 r2 establishes deep freezing duration
- parameter r8 establishes the work set-point during deep freezing.
Operate as indicated to stop the cycle:
6.
Hold the START/STOP key down.
During deep freezing, the display shows the temperature detected by the needle probe and the LED is on.
The successive parameters establish the following values:
-
parameter r4 establishes the deep freezing end temperature
- parameter r6 establishes the maximum deep freezing duration
- parameter r8 establishes the work set-point during deep freezing.
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 deep freezing end temperature within the maximum deep
freezing duration, it means that deep freezing 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 r11 establishes the work set-point during storage.
If the temperature detected by the needle probe does not reach the deep freezing end temperature within the
maximum deep freezing duration, deep freezing 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 DEEP FREEZING key; to restore the normal display, press
and release the DEEP FREEZING key again or do not operate for 15 s.
When the temperature detected by the needle probe reaches the deep freezing end temperature, the device
automatically passes to storage in the same way as illustrated previously.
6.5 Soft deep freezing and storage
The temperature-controlled soft deep freezing and storage cycle is divided into the following three phases:
-
deep freezing soft phase
- deep freezing
- 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 DEEP FREEZING key: the LED, the LED, the HARD LED and the LED will
flash.
If parameter r21 has value 1, press and release the DEEP FREEZING key to start the cycle with timed-control:
the LED, the LED, the HARD LED and the LED will flash and the LED will switch off (press and
release the DEEP FREEZING key again to start the cycle with temperature-control).
4. Press and release the HARD/SOFT key: the HARD LED will switch off.
