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.
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.
6.4 Deep freezing and storage
The temperature-controlled deep freezing and storage cycle is divided into the following two phases:
- 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).
4.1 If parameter r19 is set at 0, the display will show the work set-point during deep freezing; this value can also
be set via parameter r8.
If parameter r21 has value 1 and it has been decided to start the cycle with timed-control, the display will show
the duration of time-controlled deep freezing; this value can also be set via parameter r2.
4.2 If parameter r19 is set at 1, the display will show the deep freezing end temperature; this value can also be set
via parameter r4.
If parameter r21 has value 1 and it has been decided to start the cycle with timed-control, the display will show
the duration of time-controlled deep freezing; this value can also be set via parameter r2.
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, 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 6.7 " Test for
verification of the correct insertion of the needle probe".
If parameter r21 has value 1 and it has been decided to start the cycle with timed-control, also the will
remain permanently on and the cycle will be started with timed-control.
5.1 If the test is completed successfully, the cycle will be started.
The maximum deep freezing 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.
